For now I am do not want to add all of these to the already too large number of motion config options. Maybe based on feedback we can permanently change the constants and add an additional auto brightness option. Or maybe a combined option that sets more constant based on an algorithm.

The text_event/%C uses the time stamp for the first image detected in a new event. Default value is %Y%m%d%H%M%S. %C is an empty string when no event is in progress (gap period expired). Pre_captured and minimum_motion_frames images are time stamped before the event happens so %C in text_left/right does not have any effect on those images. * Added new option track_auto which is a boolean option (on or off) with default value off. This enables people to start Motion with auto tracking enabled. Changing the config value for track_auto and enabling the auto tracking via the httpd track/auto has the exact same effect. * Added 3 new tracking options: track_step_angle_x, track_step_angle_y, and track_move_wait. The options track_step_angle control the movement during auto tracking and are currently only active for the pwc type tracking. The idea is that they can later also be used for the generic tracking as it evolves. The track_move_wait controls the number of frames after the camera has moved (auto or manual) during which motion detection is disabled. This option should be set so low that the motion detection is re-enabled the minute the camera is standing still again. * Added new sql_query option. This in combination with convertion specifiers incl the two new %f and %n enables the user to use any database structure they please. Adding fields is now a simple matter of modifying the sql query. * Added the %t conversion specifier which is the thread (camera) number. * Added two new conversion specifiers: %f which is filename (full path) and %n which is filetype (sqltype) valid in on_picture_save, on_movie_start, on_movie_end and sql_query. This also means that filename is no longer appended at the end of the 3 on_xxxx commands. * http control had a number of small improvements. * Added the debian sub directory so that people can build the deb package. * Enhanced netcam compatibility with Lumenera and Pixord Cameras. * Netcam feature now supports both http and ftp. * Added an infinite retry scheme for netcams that are not available when Motion is started. Instead of just dying, Motion now retries every 10 seconds until the netcam is available. Until the netcam is available Motion enters a mode showing a grey image with a text information which is fed to webcam, timelapse, snapshots, vloopback etc. If the actual height and width of the netcam does not match the dimensions in the config file Motion will perform a quick restart. * Added a better error handling of a netcam that changes dimensions while Motion is running. Instead of just writing error messages Motion restarts quickly to recover from this change. * FreeBSD Code improvements including set/get hue, saturation, contrast and brightness, support large resolutions. * RPM specs file changed as suggested for use in the Livna repository. * Changed the sequence of events connected with creating files. Data is now written to the databases (if used) before an external comments is on (on_xxxx options) allowing the external program to use the new data in the database. * Motion is now also works on MaxOSX with similar feature set as FreeBSD. Bugfixes * netcam code now waits for the next frame to arrive for a limited period in order to avoid too many duplicate images. * Motion loop resets its frame timer when the image received is from a netcam. This lowers the actual framerate of Motion to the rate the netcam can actually keep up with. * Removed all warnings when running ./configure --with-developer-flags. * Fixed error message with unknown config option. * Fixed small mistake in allocating memory for cnt->imgs.common_buffer. * Implemented a speed-up patch of the draw text feature. * Introduced check for device image size being a multiple of 16. * Switchfilter feature repaired. * Fixed small bug where motion was detected when using a tracking camera and the camera moved to center position when gap period expires. * Implemented fix to configure so that LDFLAGS from the environment are used when making the Makefile. * Changed configure so that --with-jpeg-mmx is default off as a reaction to known problems seen when using the jpeg-mmx library. * The lightswitch and switchfilter features have changed to ensure that both algorithms work on raw unfiltered motion pixels which they both were designed for. * Fixed bug related to init of mutex in netcam code. * Fixed small bug where the displayed time in the grey error image shown during start with unavailable netcam could show a garbage value under rare circumstances. * Restored the function sigchild_handler so it contains the same code as before motion-3.2.1_snap9. They is done in an attempt to fix an old problem with zombie child processes that has shown up again. * Added a work-around so people in FreeBSD that uses a capture card where input 1 is not tuner can use motion if frequency is set -1 in motion.conf or thread#.conf 3.2.4 Detailed changes for 3.2.4 snap1 * Removed all warnings originating from the motion sources when running ./configure --with-developer-flags. The modifications were done by the following people: Peter Holik, Bill Brack, Angel Carpintero and Kenneth Lavrsen. We now encourage developers to ensure that new code is checked with --with-developer-flags and code made so that no new warnings shows originating from the motion sources. http://www.lavrsen.dk/twiki/bin/view/Motion/ReduceWarningsPatch * Fixed error message with unknown config option (Bill Brack) * Fixed small mistake in allocating memory for cnt->imgs.common_buffer (Angel Carpintero). * Implemented a speed-up patch of the draw text feature (Peter Holik). http://www.lavrsen.dk/twiki/bin/view/Motion/DrawTextspeedup * http control updated: (null) messages replaced by "disabled", last parameter in conf/list are displayed correctly and only in Main thread. When motion runs with only one thread, it displays "No threads". (Angel Carpintero) * Enhanced compatibility with Lumenera (Bill Brack) * http control: selectbox instead of a textfield for changing boolean configs (Peter Holik and Angel Carpintero). http://www.lavrsen.dk/twiki/bin/view/Motion/WebhttpEnhancements. * Introduced check for device image size being a multiple of 16 (Peter Holik). http://www.lavrsen.dk/twiki/bin/view/Motion/NetcamModulo16Patch * Added the debian sub directory so that people can build the deb package (Angel Carpintero). * Sync configure.in.freebsd (adding support for jpeg-mmx, developer-flags and some cosmetic changes ) (Angel Carpintero) * Implemented --with-developer-flags fixes in FreeBSD code (Angel Carpintero). * Implemented Threadnr in TLS (thread-local storage)patch. It puts the thread number into TLS and modifies motion_log() so that we do not have to drag the cnt struct around just to be able to print the thread number in the log and on the console. (Per Jönsson with additional removal of unused cnt by Kenneth Lavrsen). http://www.lavrsen.dk/twiki/bin/view/Motion/ThreadNrTlsPatch * Moved the motion_loop initialization into a new function motion_init (Bill Brack). * Removed old unused code related to read mode (not mmap) from V4L devices (Kenneth Lavrsen). * In v4l_start change map from unsigned char * to void * to be ANSI C compliant with mmap (Angel Carpintero) * http control: Changed disabled to (not defined) when displaying option list (Angel Carpintero) * netcam code now waits for the next frame to arrive for a limited period in order to avoid too many duplicate images (Bill Brack). * Motion loop resets its frame timer when the image received is from a netcam. This lowers the actual framerate of Motion to the rate the netcam can actually keep up with. (Kenneth Lavrsen) * Last --with-developer-flags warnings eliminated simply by swapping the order of the #include statements in the sources (Bill Brack and Kenneth Lavrsen). * FreeBSD Code improvements by Angel Carpintero * Implemented set/get hue , saturation , contrast and brightness. * Better support to capture with big resolution ( 640x480 , 768x576 ). * Update Readme adding information about "how to configure a capture card and settings" , update packages dependencies . * Remove support for libjpeg-mmx , motion segfault ( future fix ). * Cosmetics changes in configure.in.freebsd ( replace --without-v4l by without-bktr ). * Cleanup code and fix warnings. snap2 * Simplified rotation code based on the fact that images must have dimensions that are a multiple of 16 (Per Jönsson) http://www.lavrsen.dk/twiki/bin/view/Motion/RotateSimplificationPatch * Switchfilter feature repaired. It was called inside motion_detected() after overlays on cnt->img.out were added which meant that the feature also detected all the overlays, smartmasks, fixed mask and text. It is now moved to the motion_loop right after the lightswitch feature and before any overlays are added (Kenneth Lavrsen). * Fixed small bug where motion was detected when using a tracking camera and the camera moved to center position when gap period expires. The fix includes gathering the updating of reference frame in one place only in the motion_loop (Kenneth Lavrsen). * Implemented the new text option text_event and new conversion specifier %C. Option text_event defines the value %C which then can be used in filenames and text_right/text_left. The text_event/%C uses the time stamp for the first image detected in a new event. Default value is %Y%m%d%H%M%S. %C is an empty string when no event is in progress (gap period expired). Pre_captured and minimum_motion_frames images are time stamped before the event happens so %C in text_left/right does not have any effect on those images (Kenneth Lavrsen). http://www.lavrsen.dk/twiki/bin/view/Motion/EventConvertionSpecifierDiscussion * Renamed some variables related to time to be better descriptive of function and type (Kenneth Lavrsen). * Added new option 'sql_user_text'. This can be defined with the same conversion specifiers as text_xxx, on_xxxx and filenames. The SQL field text_left has been removed and replaced by a field user_text which is used for storing the interpreted value of sql_user_text (Kenneth Lavrsen) * Added new SQL field event_time_stamp of the type TIMESTAMP (Kenneth Lavrsen). snap3 * Enhancement to Netcam Code for Connection to Pixord Cameras (Bill Brack). http://www.lavrsen.dk/twiki/bin/view/Motion/NetcamFixPixordBug * Implemented fix to configure so that LDFLAGS from the environment are used when making the Makefile (Angel Carpintero). http://www.lavrsen.dk/twiki/bin/view/Motion/BugReport2005x09x15x185558 * Changed configure so that --with-jpeg-mmx is default off as a reaction to known problems seen when using the jpeg-mmx library (Angel Carpintero). * RPM specs file changed as suggested for use in the Livna repository. (Kenneth Lavrsen) * The lightswitch and switchfilter features have been moved up before the despeckle features are run. This should ensure that both algorithms work on raw unfiltered motion pixels which they both were designed for. (Kenneth Lavrsen) http://www.lavrsen.dk/twiki/bin/view/Motion/BugReport2005x10x05x212444 snap4 * Integrated NetcamWithFtp patch. To use ftp simply use a URL starting with ftp:// (Bill Brack). Code was additionally cleaned up by Kenneth Lavrsen. http://www.lavrsen.dk/twiki/bin/view/Motion/NetcamWithFTP * Changed error handling in vid_start so that failing to open the video device no longer causes an exit but a return with error code -1. (Kenneth Lavrsen) * Added the %t conversion specifier to show the thread number. (Angel Carpintero). http://www.lavrsen.dk/twiki/bin/view/Motion/ThreadConversionSpecifierPatch * Added help texts in conf.c and motion-dist.conf describing the %t specifier. Added a good example of use in motion-dist.conf. (Kenneth Lavrsen). * Fixed bug related to init of mutex in netcam code (Angel Carpintero). * Improved fix for netcam mutex init (Bill Brack). http://www.lavrsen.dk/twiki/bin/view/Motion/NetcamFixPthreadInit * Netcam_ftp code fixes (Angel Carpintero and Asbjørn Pettersen) http://www.lavrsen.dk/twiki/bin/view/Motion/NetcamWithFtpEnhancements * Enhanced ffmpeg detection (Angel Carpintero). http://www.lavrsen.dk/twiki/bin/view/Motion/BetterFFmpegDetection * Added two new conversion specifiers: %f which is filename (full path) and %n which is filetype (sqltype) valid in on_picture_save, on_movie_start, on_movie_end and sql_query. This also means that filename is no longer appended at the end of the 3 on_xxxx commands. (Kenneth Lavrsen) * Removed the sql_user_text option that was added in snap 2 (Kenneth Lavrsen) * Added new sql_query option. This in combination with convertion specifiers incl the two new %f and %n enables the user to use any database structure they please. Added fields is now a simple matter of modifying the sql query. The default is the same as the default in snap1. (Kenneth Lavrsen). * Changed the sequence of events connected with creating files. Data is now written to the databases (if used) before an external comments is on (on_xxxx options) allowing the external program to use the new data in the database (Kenneth Lavrsen). * Added an infinite retry scheme for netcams that are not available when Motion is started. Instead of just dying, Motion now retries every 10 seconds until the netcam is available. Until the netcam is available Motion enters the normal flow with the same grey image with a text information being fed to webcam, timelapse, snapshots, vloopback etc. Motion uses the width and height from the config file for this. It is a good idea to setup width and height so it is the same as the netcam. If the dimensions are the same Motion will switch over to the netcam seemlessly. If the dimensions are different Motion will perform a quick restart so all the many internal buffers can be initialized properly (Kenneth Lavrsen). * Added a better error handling of a netcam that changes dimensions while Motion is running. Instead of just writing error messages Motion restarts quickly to recover from this change. Note the now more well defined error coding for vid_next for both netcams and V4L cams. (Kenneth Lavrsen) snap5 * Fixed small bug where the displayed time in the grey error image shown during start with unavailable netcam could show a garbage value under rare circumstances. (Kenneth Lavrsen). * Restored the function sigchild_handler so it contains the same code as before motion-3.2.1_snap9. They is done in an attempt to fix an old problem with zombie child processes that has shown up again. http://www.lavrsen.dk/twiki/bin/view/Motion/BugReport2005x11x13x115016 (Kenneth Lavrsen). * Move the declaration of sig_handler_action and sigchild_action from the setup_signals function where they are local and will be destroyed and out in main just before setup_signals is called. Changed the function setup_signals so the two structs are passed as pointers. (Kenneth Lavrsen) Release * Added new option track_auto which is a boolean option (on or off) with default value off. This enable people to start Motion with auto tracking enabled. Changing the config value for track_auto and enabling the auto tracking via the httpd track/auto has the exact same effect. (Kenneth Lavrsen) * Added 3 new tracking options: track_step_angle_x, track_step_angle_y, and track_move_wait. The options track_step_angle control the movement during auto tracking and are currently only active for the pwc type tracking. The idea is that they can later also be used for the generic tracking as it evolves. The track_move_wait controls the number of frames after the camera has moved (auto or manual) during which motion detection is disabled. This option should be set so low that the motion detection is re-enabled the minute the camera is standing still again. Feature originally made by Moshe Van Der Sterre. Kenneth Lavrsen extended it to be more generic. http://www.lavrsen.dk/twiki/bin/view/Motion/PwcConfiguration * New Feature: Motion is now also supported on MaxOSX with similar feature set as for Free BSD. See README.MacOSX for details how to install it. (Angel Carpintero) http://www.lavrsen.dk/twiki/bin/view/Motion/MacOSXPatch * Added a work-around so people in FreeBSD that uses a capture card where input 1 is not tuner can use motion if frequency is set -1 in motion.conf or thread#.conf (Angel Carpintero). 3.2.3 Detailed changes for 3.2.3 Bugfix release only. No new features. * Fixed a bug in the http control code that failed to accept a client connecting in some systems (Peter Holik). * Fixed a series of bugs where several feature were using the image buffer after text was added for noise tuning, auto_brightness, reference frame update when tracking etc. When a netcam failed to produce an image the text added to the previous image became motion detected also. The code is not changed so that the ring buffer is used for timestamped images and the image used for detection is in a buffer cnt->imgs.image_virgin. (Kenneth Lavrsen). http://www.lavrsen.dk/twiki/bin/view/Motion/BugReport2005x08x15x140701 * Auto brightness used the first image in ring buffer instead of the latest image and it used an image with time stamping. It now uses the new cnt->imgs.image_virgin buffer. http://www.lavrsen.dk/twiki/bin/view/Motion/BugReport2005x08x15x160208 * Cleaned out unused code from httpd control (Angel Carpintero). * Option switch_filter used print_int instead of print_bool when motion.conf was saved (Kenneth Lavrsen). 3.2.2 Formal Release. Summary of changes Features * New completely rewritten netcam code. * Proxy servers are again supported by netcam feature * New conversion specifier %o for threshold * New convertion specifier %Q for number of labels * Drawing of mask and smartmask in setup mode improved * Compilation of motion on 64 bit machines improved * RPMs can now be built by non-root user * Improved the labelling algorithm so that locate feature and tracking features includes all labelled areas above threshold * Motion now supports the mjpeg webcam stream while saving PPM images. * New improved webcam feature. When you set webcam_motion on Motion will now stream at 1 fps instead of none. When motion is detected the webcam stream increases to the limit set in the config file. This change makes the webcam_motion much more interesting. The previous function always ended up with clients timing out. * Implemented the libjpeg-mmx patch. Installing the MMX version of libjpeg can increase performance. Especially for machines with very little CPU power. It only modifies the configure script. If you do not have the libjpeg-mmx the configure script with ignore this and use the standard libjpeg. Note that RPMS will be built without this * Improved descriptions in motion.conf * Many small code speed optimizations. * Added new feature: Double size text. A new config option 'text_double' can be set 'on' and this scales the text to double size. Default is off. * Improved error handling of missing picture frames from camera. Especially network cameras will often not be able to provide a picture frame from time to time. Motion would retry before and eventually and rather quickly exit the camera thread and maybe completely exit. The improved handling now makes a copy of the previous frame for 30 seconds (longer if cpu_low is activated because the implementation is 30 X framerate frames) and then show a grey image with a message saying the connection is lost and an ISO format time stamp of first poor connection. * Added a configure option --with-developer-flags which enables many compiler warnings that can be used by developers to make code more robust. Not for normal users building Motion. * Included a CODE_STANDARD text file to help new developers make patches that are easier to integrate without too much manual editing. Bug Fixes * Fixed a bug in the autobrightness algorithm * Fixed bug reporting errors when creating symlink to last snap * Improved code so that Motion no longer uses the tmpfile() function for buffering the frames of the mjpeg stream. * Implemented a fix/work around to a bug related to building and installing RPMs on Suse. * Improved signal handler * Code commented much more. * Many bugfixes to get Motion more stable (less segfaults) * Code improved to remove all warnings when compiled with gcc 4.0 * Better FreeBSD support * Replace functions not threadsafe with threadsafe functions. * Implemented a much easier to use motion_log function which replaces the calls to printf and syslog. This code change as no impact to the user. * Fixed a bug in video.c so that VIDEO_PALETTE_GREY cameras now actually work. * Updated the ffmpeg.c code so that Motion can now be built with ffmpeg CVS release from the June/July 2005 timeframe. 3.2.2 Detailed changes for 3.2.2 snap1 * Pthread deadlock in motion 3.2.1 fixed (Angel Carpintero) http://www.lavrsen.dk/twiki/bin/view/Motion/BugReport2005x05x26x125712 * http lockup bugfixes and ConvertSignalToSigaction only for webhttpd (Angel Carpintero) * alg_draw_location: Use temporary variables to store the values used in for() loops instead of compute them in each loop (Angel Carpintero). http://www.lavrsen.dk/twiki/bin/view/Motion/ImproveAlgDrawLocation * Small speed boost to the function draw_textn (Andrew Hamilton and Angel Carpintero). http://www.lavrsen.dk/twiki/bin/view/Motion/DrawTextnImprovement * Added two new convertion specifiers: %o for threshold and %Q for number of labels. (Kenneth Lavrsen) * Improved the config file description for pre_capture to get people to use small values (Kenneth Lavrsen). snap2 * Avoid Cleanup Segfault. Avoid Cleanup Segfault. Allocates filepath using strdup to avoid segfault is target_dir parameter is not supplied in motion.conf. Moves out from signal handler the cleanup for pipe and mpipe. (Angel Carpintero) http://www.lavrsen.dk/twiki/bin/view/Motion/AvoidCleanupSegfault * Major code cleanup concerning signedness of chars all over the code to allow compilation with gcc4.0 (like in Fedora Core 4) without any errors or warnings. This will probably require that some of the not yet included patches will have to be fixed because it it code all over the place that has been changed. (Kenneth Lavrsen) snap3 * Changed the order of drawing the red mask in setup mode so that the smartmask is drawn after the fixed mask (Joerg Weber). * Changed the configure script so that /usr/lib64 is also searched for the presence of ffmpeg (should fix the problem with 64 bit machines) (Kenneth Lavrsen). * Changed the configure script so that rpms can be made by normal non-root users (Angel Carpintero, Kenneth Lavrsen). snap4 * Fixed the ffmpeg code so that Motion also compiles against libavcodec build 4754 or later. (Per Jönsson) * Above change in configure script for 64 bit ffmpeg support also implemented in the freeBSD configure (Angel Carpintero) * Webhttp control interface fixed so it also works in FreeBSD (Angel Carpintero) * Improved the display of fixed mask. It is now shown as grey instead of red. This makes it easier to see the smart mask working when you also have a fixed mask (Joerg Weber). * Netcam First Header patch. If an error with jpeg decompression occurred at connecting to a mjpeg streaming webcam, this patch skips this jpeg and tries to decompress next jpeg up to MAX_HEADER_RETRIES (20) (Peter Holik). http://www.lavrsen.dk/twiki/bin/view/Motion/NetcamFirstHeader snap5 * Small improvement in framerate accuracy (Peter Holik). http://www.lavrsen.dk/twiki/bin/view/Motion/FramerateAdjust * Fixed a bug in the autobrightness algorithm (Per Johnsson) * Fixed a bug in the webhttpd code related to pan/tilt. Bug was introduced in snap4 (Angel Carpintero, Kenneth Lavrsen). * Improved the labelling algorithm so that locate feature and tracking features includes all labelled areas above threshold (Joerg Weber). http://www.lavrsen.dk/twiki/bin/view/Motion/ImprovedLabellingPatch * Fixed bug reporting errors when creating symlink to last snap (Bill Maidment) * Changed all use of localtime to localtime_r which is threadsafe (Kenneth Lavrsen). * Implemented a modified version of the WebcamCompressInMemory so that Motion no longer uses the tmpfile() function for buffering the frames of the mjpeg stream (Peter Holik). http://www.lavrsen.dk/twiki/bin/view/Motion/WebcamCompressInMemory * Modified the WebcamCompressInMemory patch so that Motion now supports the mjpeg webcam stream while being setup for saving PPM images (Kenneth Lavrsen). http://www.lavrsen.dk/twiki/bin/view/Motion/WebcamCompressInMemory * Major clean-up of code in picture.c and webcam.c so that function names and variable names are less confusing. Also added many comments in picture.c. (Kenneth Lavrsen). snap6 * Webcam code commented more (Kenneth Lavrsen) * New improved webcam feature. When you set webcam_motion on Motion will now stream at 1 fps instead of none. When motion is detected the webcam stream increases to the limit set in the config file. This change makes the webcam_motion much more interesting. The previous function always ended up with clients timing out. (Kenneth Lavrsen). snap7 * Implemented WebcamShortWriteHandling patch (Bill Brack) http://www.lavrsen.dk/twiki/bin/view/Motion/WebcamShortWriteHandlingPatch * Implemented the libjpeg-mmx patch. Installing the MMX version of libjpeg can increase performance. Especially for machines with very little CPU power. It only modifies the configure script. If you do not have the libjpeg-mmx the configure script with ignore this and use the standard libjpeg. Note that RPMS will be built without this (Peter Holik and Angel Carpintero). http://www.lavrsen.dk/twiki/bin/view/Motion/LibJpegMmx snap8 * Small code cleanup in webcam.c and picture.c and .h for the webcam code (Peter Holik and Kenneth Lavrsen) * Small code cleanup in motion.c for the variable holding the number of microseconds since epoch. The old code worked fine but relied on an integer overflow every 71 minutes. (Bill Brack and Kenneth Lavrsen) * Implemented a fix/work around to a bug related to building and installing RPMs on Suse. (Paul Beltrani) http://www.lavrsen.dk/twiki/bin/view/Motion/BugReport2005x07x14x212356 * Small speed optimization in the creation of reference frame (Peter Holik). * Complete rewrite of the Netcam code. Should fix many of the reported and still open netcam bugs. This is first release in a snapshot. Expect to find bugs. Testing is important. If you have a netcam please test this and report bugs. http://www.lavrsen.dk/twiki/bin/view/Motion/NetcamCodeRewritePatch snap9 * Fixed bug related to disabled webcam or duplicate webcam port. Error log accept(): Socket operation on non-socket continuously written to syslog. (Kenneth Lavrsen) http://www.lavrsen.dk/twiki/bin/view/Motion/BugReport2005x08x01x150922 * Fixed memory leak in webhttpd related to use of strdup (Angel Carpintero). * Improved the error reporting in the Netcam code and did a few minor corrections and code cleanups (Bill Brack). * Implemented a much easier to use motion_log function which replaces the calls to printf and syslog. The implementation to actually use this has been implemented in video.c and the Netcam code files. Rest will be in next snap. This code change as no impact to the user (Bill Brack). http://www.lavrsen.dk/twiki/bin/view/Motion/ErrorLoggingEnhancementPatch * Fixed a bug in video.c so that VIDEO_PALETTE_GREY cameras now actually work (Bill Brack). * Implemented the conversion of signal to sigaction which should be more thread safe. Hopefully this still keeps Motion from making Zombies. (Christophe Grenier). http://www.lavrsen.dk/twiki/bin/view/Motion/ConvertSignalToSigaction * Added new feature: Double size text. A new config option 'text_double' can be set 'on' and this scales the text to double size. Default is off. (Andrew Hamilton). http://www.lavrsen.dk/twiki/bin/view/Motion/TextScalingPatch snap10 * Error Logging Enhancement Patch v 1.3 (Angel Carpintero) including: http://www.lavrsen.dk/twiki/bin/view/Motion/ErrorLoggingEnhancementPatch * Populate the motion_log to the whole motion source code. * Fixed FreeBSD compilation. * Added the possibility to pass NULL as struct context * * Removed unused errno variables. * Fixed errno in rotate.c , set to 0. * Fixed some errno flags in webhttpd.c and motion.c * Fixed a bug when not motion.conf is found * Removed printf from all files * Fixed the conf_list[] index in motion.c * RotateBswapFix Patch v 2 (Per Jönsson) including: * cleanup in code comments * fix for __bswap_32 macro collision * fixed bug where initialization would be incomplete for invalid degrees of rotation * now uses motion_log for error reporting http://www.lavrsen.dk/twiki/bin/view/Motion/RotateBswapFix * Re-mplementation of optional Proxy Server for Network Cameras (Bill Brack). http://www.lavrsen.dk/twiki/bin/view/Motion/NetcamProxyServerPatch * Included a CODE_STANDARD text file to help new developers make patches that are easier to integrate without too much manual editing. (Kenneth Lavrsen) * Added the missing rotate feature in the new netcam code (Bill Brack) snap11 * Updated the ffmpeg.c code so that Motion can now be built with ffmpeg CVS release from the June/July 2005 timeframe (Per Jönsson). http://www.lavrsen.dk/twiki/bin/view/Motion/FfmpegCodecPatch * Improved error handling of missing picture frames from camera. Especially network cameras will often not be able to provide a picture frame from time to time. Motion would retry before and eventually and rather quickly exit the camera thread and maybe completely exit. The improved handling now makes a copy of the previous frame for 5 seconds (longer if cpu_low is activated because the implementation is 5 X framerate frames) and then show a grey image with a message saying the connection is lost and an ISO format time stamp of first poor connection. (Kenneth Lavrsen). * Implemented version 2 of the NetcamErrorImprovementPatch which should work with the improved error handler. Changes include: * Changes handling of non-streaming camera to include a separate thread. * Changes the value returned from netcam_next to the motion main loop to indicate the status of the image returned. * Many changes to the comments, and some enhancement to the logic, to begin the implementation of points agreed on the NetcamRetryErrorDiscussion page. * Implements the triple-buffering scheme proposed by PeterHolik (but not the "Without Locking" portion of his proposal). Version 2 however does not seems to recover when an mjpeg stream resumes after a period of not being available. (Bill Brack) http://www.lavrsen.dk/twiki/bin/view/Motion/NetcamErrorImprovementPatch * Note: Snap11 release as a developer sync release. Bug reports welcome. FreeBSD code changes not tested yet. Release * Netcam error handling improvements and cleanup from Valgrind analysis (Bill Brack). * Added a configure option --with-developer-flags which enables many compiler warnings that can be used by developers to make code more robust. Not for normal users building Motion (Bill Brack) * http-control: Fixed segfault when motion is restarted from command line ( kill -s 1 pid_motion ). Improved control code so Motion can Restart and Finish 'smoothly'. (Angel Carpintero). http://www.lavrsen.dk/twiki/bin/view/Motion/MotionHttpControl * Changed the 5 second missed camera signal timeout to 30 seconds. (Kenneth Lavrsen) * Fixed bug where an extra jpeg is saved if you have output_normal=best and you stop motion after an event has ended. (Kenneth Lavrsen) http://www.lavrsen.dk/twiki/bin/view/Motion/BugReport2005x08x05x173526 3.2.1 Detailed changes for 3.2.1 since 3.1.19_snap3 snap1 * Major new feature. XMLRPC is replaced by a simpler http remote control interface (implemented by Angel Carpintero) http://www.lavrsen.dk/twiki/bin/view/Motion/MotionHttpControl snap2 * Fixed netcam->userpass problem (Angel Carpintero) * Added support in configure for athlon64 from http://www.lavrsen.dk/twiki/bin/view/Motion/BugReport2005x01x30x190907 (Angel Carpintero and William M Brack) * Fixed some gcc warnings (William M Brack) * Code cleanup from a valgrind analysis (William M. Brack). snap3 * Added Best Preview Patch (Joerg Weber) http://www.lavrsen.dk/twiki/bin/view/Motion/BestPreviewShot snap4 * Fix for tracking control with http control (Angel Carpintero) * Added the new feature Setup Mode (Joerg Weber). This also enables much more error messages given to the console when in non-daemon mode while still preserving the messages in syslog which are important for daemon mode debugging. The patch is still being worked on and is not finished. Changes in the FreeBSD code are not yet tested. http://www.lavrsen.dk/twiki/bin/view/Motion/SetupModePatch Remove most command line options and replace them by an option to specify location to motion.conf and a few options related to setting up motion. (Joerg Weber). This is also included in SetupModePatch. * Small improvement of the http control interface (link to setting itself on the html response when setting parameter) (Kenneth Lavrsen) snap5 * Fixed a bug in noise tune which was most visible at very low light. (Joerg Weber and Kenneth Lavrsen) * Further improvement in the setup mode. Messages are now prefixed by the thread number in [brackets]. Moved 2 functions from motion.c to picture.c. The setup mode patch is now considered finished. (Joerg Weber) snap6 * Netcam fixes and debug code by Christopher Price http://www.lavrsen.dk/twiki/bin/view/Motion/NetcamStabilityPatch snap5_post1_video.c and snap5-post1 patches * Fixed netcam startup race condition. * Refactored image handling back to single unified function * Refactored reconnection algorithm * Jpeg only based connections should now use less cpu time * Temporarily removed support for devices that do not support content-length (in progress) * Synced syslog/printf style to new motion standard * Added developer debug trace defines/code * Defines now used for many constants snap7 * Improved console output in setup mode. Now also outputs threshold. (Joerg Weber) * Added some additional text to the motion http messages to the terminal so that you know where the messages come from. (Kenneth Lavrsen) Netcam Stability Patch version snap6-post1 (Christopher Price) * Added support for netcams without content-length header (streaming only) * Remove memmem from netcam_wget.[c|h] (no longer used) * Several miscellaneous code cosmetic changes * TODO: remove tests for memmem from configure snap8 * Added support for non-streaming (image based) netcams without content-length header. (3.2.1-snap7-post1 version of the Netcam Stability Patch by Christopher Price). * Improvement in the noise-tune algorithm (Joerg Weber) * Re-arranged many of the const char declarations so that they are always before any statements within a block { }. This is to avoid compiler errors with older but still used gcc versions such as 2.95. (Kenneth Lavrsen) * Changed the use of %zd to %llu in printf statements of size_t types. This is done to avoid compiler errors with older but still used gcc versions such as 2.95. (Kenneth Lavrsen) snap9 * Fixed even more gcc 2.95 compiler errors (declarations not at beginning of block) (Kenneth Lavrsen). * Removed a gcc 2.95 compiler warning (netcam.c:1036: warning: variable `pic' might be clobbered by `longjmp' or `vfork') (Kenneth Lavrsen) * The values for cnt->locate and cnt->new_img are now #defines in motion.h to enhance code readability (Kenneth Lavrsen). * The setting of sql_mask is now only done once per second to save CPU power (Kenneth Lavrsen) * Adding checking for conflict between control port and webcam port. Webcam port for a thread is disabled if it is set to the same value as the control port (Kenneth Lavrsen). * Fixed some file descriptor leaks in webcam.c and netcam.c (Christophe Grenier) * Added "motion-http:" prefix to error messages from the http control thread. (Kenneth Lavrsen) * Added additional error information when connection to MySQL fails (Kenneth Lavrsen) * Initiate cnt->event_nr to 1 to avoid code related to end of events and long mpeg films to be run during startup of Motion. (Kenneth Lavrsen) * Added new function in event.c close_anything_open() which is called from send_sms, send_mail and exec_command in order to prevent file descriptor and open sockets to be inherited by the shell causing freezing and instability. Code contributed by Christophe Grenier, Christopher Price and Kenneth Lavrsen. * Added new context global cnt_list.control_socket_server set by the httpd thread so that the above mentioned close_anything_open() can close open control sockets (Kenneth Lavrsen). * Renamed the top level global context structure to cnt_list so it can be reached from child threads and by above mentioned close_anything_open() (Christophe Grenier). snap10 * Fixed a problem when compiling with --without-v4l configuration. (Philip Marien) http://www.lavrsen.dk/twiki/bin/view/Motion/BugReport2005x03x27x112843 * Threw away the file descriptor leak fix from snap 9 because it caused more trouble than it fixed. Removed the close_anything_open() and the cnt_list.control_socket_server field. Replaced it all with a simple piece of code that all server daemons call when started: setsid() followed by for (i=getdtablesize(); i>2; --i) close(i). Dirty and simple. (Kenneth Lavrsen) http://www.lavrsen.dk/twiki/bin/view/Motion/BugReport2005x03x21x070534 * Fixed a bug where rate of fetching picture frames was disturned by the signal SIG_CHLD from exec_command programs terminating. The symptom was that the number of post_capture frames became inaccurate and motion in mpegs did not have constant time between frames. (Kenneth Lavrsen) * Fixed a bug where motion did not work with gap=1 (Kenneth Lavrsen). http://www.lavrsen.dk/twiki/bin/view/Motion/BugReport2005x01x30x073616 * Added the feature gap=0 which now also works. It disables gap completely so that one single mpeg file is created. You can end the event from the remote control interface make movie feature using for example cron. This makes Motion close the mpeg and make a new with event number increased by one. (Kenneth Lavrsen) * Improved the http remote control action features so that makemovie and snapshot for thread 0 (all) works on all threads instead of being ignored (Kenneth Lavrsen). * Moved some code in the beginning of the motion_loop to a position later to improve the accuracy of time calculations for the framerate (Kenneth Lavrsen) * Updated code so Motion again runs on FreeBSD (Angel Carpintero). * Removed check for memmem from configure (Angel Carpintero). * Updated http control interface so that an additional check is done before saving config files (Angel Carpintero). * Fixed a problem with URLs http://192.168.1.3:8080/0 which did not work without a trailing space (Angel Carpintero). snap11 * Implemented new Generic onxxxx features. Function --- Old Option --- New Option Start of event (first motion) --- execute --- on_event_start End of event (no motion for gap seconds) --- New! --- on_event_end Picture saved (jpg or ppm) --- onsave --- on_picture_save Movie starts (mpeg file opened) --- onmpeg --- on_movie_start Movie ends (mpeg file closed) --- onffmpegclose --- on_movie_end Motion detected --- New! --- on_motion_detected http://www.lavrsen.dk/twiki/bin/view/Motion/OnXxxCommandsPatch and http://www.lavrsen.dk/twiki/bin/view/Motion/OnXxxxFeatureDiscussion (Joerg Weber) * More Netcam Stability Fixes (snap10-post1-6) (Christopher Price) http://www.lavrsen.dk/twiki/bin/view/Motion/NetcamStabilityPatch * Destroy mutexes in netcam_cleanup(). * Add reconnection for netcam_start() - this may block other cameras from starting up!. * Added additional defines for reconnect retries. * Change reconnection timeouts to 60 seconds. * Reworked close(sock) in netcam_connect, to insure future changes won't forget to close the socket. * Reworked reconnection for netcam_start() - disabled by default, see source for INIT_RECONNECT_RETRIES. * Break some long lines in code. * Replaced sleep with nanosleep per suggestion by Kenneth Lavrsen. * Added additional header validation check. * Changed a couple fd references to use RBUF_FD. * Added error message if jpeglib error occurs. * Removed additional header validation check. * Limited times headers will be checked. * Removed mutex lock around netcam_start() in video.c, hopefully race conditions are fixed. * Added additional headers in http request. * Added back header validation (should fix netcam_read_header lockups). * Detect when there is no data on socket in netcam_read_ functions (should fix netcam_read_image_contentlength() and netcam_read_image_no_contentlength() lockups). * Rearranged timeout assignments for pthread_cond_timedwait() calls. * Adjusted TIMEOUT_COND_WHICH to 4 seconds. * Improvements of motion.conf help comments including improvements in new onxxxx options. (Kenneth Lavrsen) snap12 * Fixed a bug in the rgb2yuv420p function. (Daniel Ladd) http://www.lavrsen.dk/twiki/bin/view/Motion/BugReport2005x03x30x011107 * Fixed a bug of locate feature for movement images combined with the new output_normal best feature (Joerg Weber) * More Netcam Stability Fixes (snap11-post1-4) (Christopher Price) http://www.lavrsen.dk/twiki/bin/view/Motion/NetcamStabilityPatch * Reworked thread signal/wait conditions, should fix some race conditions. * Use gettimeofday() to determine thread timeouts, results in better accuracy. * Adjusted condition timeouts to smaller values due to usage of gettimeofday() and rework of thread signal/wait conditions. * Adjusted reconnection retries to 60 (every minute for an hour). * Fix bug where motion will not quit if requested when reconnecting. * Cruft, feature creep and redundant code removed. * Consolidated reconnection capability to unified netcam_reconnect function. * Rework netcam_start logic, minimize startup variables. * Rework netcam_stream_read and netcam_single_read logic. * Minor changes to netcam_next logic. * Fix bug in streaming camera without content-length, recent mod broke. * Fix bug in startup of single image reads without content-length. * Motion Guide refactored completely for 3.2.1 with better web navigation and auto generation of pages. Makefile updated so that the Motion TWiki topic MotionGuideOneLargeDocument is fetched when updating the guide and making releases. (Kenneth Lavrsen). snap13 * Removed the debug_parameter option which had no use. Programmers can still use it because the code is only commented out. This change required a small update in the code that rewrites motion.conf so that a remote control command to write the config files still adds a text header for the thread section at the end of motion.conf (Kenneth Lavrsen). * Changed the default values for a few options: quiet on, webcam_maxrate 1, threshold_tune off, webcam_quality 50 (Kenneth Lavrsen). * Changed some cosmetics in the way motion.conf is written (space after #) (Kenneth Lavrsen). * Updated the motion-dist.conf to use default values unless there is a reason not to (Kenneth Lavrsen). * Fix the compile issue with official ffmpeg packages from debian (Angel Carpintero). * More Netcam Stability Fixes (snap12-post1) (Christopher Price) * Newrote url parser, better syntax checking and error handling of urls. * Userpass now allowed in url (http://user:pass@example.com/). Netcam_userpass has precedence, it will override a userpass embedded in the url. http://www.lavrsen.dk/twiki/bin/view/Motion/NetcamStabilityPatch snap14 * Added basic authentication to the http control interface introducing new config option control_authentication. (Angel Carpintero) * Fixed memory leak when restarting Motion from http control (Angel Carpintero). * Small improvement in configure script for Debian (Angel Carpintero) * Added the ability to clear an option to off (bool), 0 (int) or undefined (string) by submitting blank entry field in the http control interface. (Angel Carpintero). snap15 * Added new feature which shows the fixed mask (in addition to the smart mask) in bright red on the Motion type images (Joerg Weber). http://www.lavrsen.dk/twiki/bin/view/Motion/FixedMaskFileOnMotionImagesPatch * Added new feature. When you specify a mask file in the config file and start Motion, and the mask file does not exist, Motion will create a new clear (white) mask file for you in the right size. Then it is easy to simply open the file in your favourite paint program and add the masking in black (Joerg Weber). http://www.lavrsen.dk/twiki/bin/view/Motion/FixedMaskFileOnMotionImagesPatch * Fixed a bug in the low_cpu feature where cpu load increased instead of decreasing because the framerate calculations were completely wrong. This was an old bug introduced in 3.0.1 (Kenneth Lavrsen). http://www.lavrsen.dk/twiki/bin/view/Motion/BugReport2005x04x24x205933 * Improved the auto-brightness algorithm. When auto-brightness is enabled the brightness option becomes a target value for the brightness level. This should also close a bug report (Kenneth Lavrsen). http://www.lavrsen.dk/twiki/bin/view/Motion/BugReport2005x02x26x195358 * http interface small fixes (motion-3.2.1_snap14-small-fixes 1.1) incl Add 'back' link to response_client errors (Angel Carpintero). http://www.lavrsen.dk/twiki/bin/view/Motion/MotionHttpControl * Started adding tuner_number as option. This is not fully implemented. First code is added and rest will be done in next snap. (Kenneth Lavrsen) snap16 * Made the http control interface more RFC compliant (Angel Carpintero). http://www.lavrsen.dk/twiki/bin/view/Motion/BugReport2005x05x02x180550 * Made the http control HTML responses nicer to look at as sources and therefore easier to debug errors (Kenneth Lavrsen). * Code style cleanup of webhttpd.c (Kenneth Lavrsen). * Fixed compatibility problem with Palantir. Fixed by making output more compatible with RFC (\r\n). Original fixes by Roberto Spadim and Angel Carpintero. However this fix made Firefox flicker even more than it normally does. Final fix which works in both Palantir client, Firefox and Cambozola was made by Kenneth Lavrsen. This closes the following bugs: http://www.lavrsen.dk/twiki/bin/view/Motion/BugReport2005x05x02x205307, http://www.lavrsen.dk/twiki/bin/view/Motion/BugReport2005x05x07x042849 snap17 * Fixed small bug when pre_capture buffer is resized during operation. (Joerg Weber). * In httpd control code: Fixed RAW syntax following API specs. (Angel Carpintero). http://www.lavrsen.dk/twiki/bin/view/Motion/MotionHttpControl * Added new conversion specifiers: %D (diffs), (noise) %K (motion center x), %L (motion center y), %i (locate width x) and %J (locate width y). These changes also required a refactoring of the alg_locate code. This change is part of the implementation of a generic tracking feature and it enables implementing external programs that can perform simple prediction features. (Kenneth Lavrsen) http://www.lavrsen.dk/twiki/bin/view/Motion/ExtendReplaceConversionSpecifiersDiscussion http://www.lavrsen.dk/twiki/bin/view/Motion/GenericTrackingPatch * Fixed a bug in switchfilter which caused motion detection to not work when the feature was enabled (Kenneth Lavrsen). Release * Change the working directory to / in daemon mode. This way you don't have to kill motion to umount the partition from where you start it. (Christophe Grenier) http://www.lavrsen.dk/twiki/bin/view/Motion/ChdirNetCamWgetPatch * In netcam-wget header_get() didn't always in add a \0 string terminator. This was fixed by Christophe Grenier http://www.lavrsen.dk/twiki/bin/view/Motion/ChdirNetCamWgetPatch * Fix for Unknown content type with lumenera cameras (Kenneth Lavrsen) http://www.lavrsen.dk/twiki/bin/view/Motion/BugReport2005x05x06x174416 * MotionHttpControl Patch motion-3.2.1_snap18-pre1 v,1.0 19 May 2005. Fixed some HTTP response codes and added header copyrights. (Angel Carpintero). http://www.lavrsen.dk/twiki/bin/view/Motion/MotionHttpControl * Implemented pthread fix by Christophe Grenier. http://www.lavrsen.dk/twiki/bin/view/Motion/PthreadFixPatch * Fixed problem compiling "ffmpeg reports only YUV420 is supported" when ffmpeg is a recent CVS version. (Angel Carpintero) http://www.lavrsen.dk/twiki/bin/view/Motion/BugReport2005x05x22x213229 * Man page updated. It is now semi-autogenerated in the Motion TWiki (Kenneth Lavrsen) http://www.lavrsen.dk/twiki/bin/view/Motion/MotionOptionsAlphabeticalManpage * Bug fix in netcam code: Sometimes motion try to free an invalid memory area (Angel Carpintero) http://www.lavrsen.dk/twiki/bin/view/Motion/BugReport2005x05x21x105335 * Small configure fix related to --without-v4l (Angel Carpintero) * Fixes for http control HTML code (Angel Carpintero) * Added init script to RPM (Angel Carpintero) 3.1.19 Detailed changes for 3.1.19 snapshot releases since 3.1.18 snap1 * Fixed bug which caused Motion 3.1.18 fail to save timelapse mpegs when setting ffmpeg_timelapse = 1 (fixed by Michael Reuschling) http://www.lavrsen.dk/twiki/bin/view/Motion/BugReport2005x01x31x211756 * Fixed several bugs in new netcam code introduced in 3.1.18 (Angel Carpintero) http://www.lavrsen.dk/twiki/bin/view/Motion/BugReport2005x01x16x030209 http://www.lavrsen.dk/twiki/bin/view/Motion/BugReport2005x02x01x071546 http://www.lavrsen.dk/twiki/bin/view/Motion/BugReport2005x02x03x035918 * Added patch that enables Motion to work with vloopback version 0.94 and kernel 2.6.10+. (patch by William M Brack). http://www.lavrsen.dk/twiki/bin/view/Motion/MotionAndVloopbackVideoDotCPatch snap2 * Following bugfixes all by Angel Carpintero * Netcam code: Change printf() to fprintf(). * Netcam code: Cleanup memory netcam (netcam.c , motion.c ). * Netcam code: Redesign of reconnection feature. * Configure: Added debug , conditional compile of xmlrpc-c * Fix a non allocated pointer to be freed. * Added fix to BugReport2005x02x11x170019 * Added fix to BugReport2005x02x11x150802 snap3 * Bugfixes by Angel Carpintero * fix motion.spec, motion.spec.in * typo in configure.in , configure.in.freebsd * fix version number 3.1.18 Formal Release - Summary of changes since 3.1.17. * Removed the Berkeley mpeg feature * New brightness, contrast, hue and saturation options. * Makefile with automatic check of dependencies and nicer user output. * Improvement of the rotate feature. * Added the new smart mask feature. * Added a new config option --without-optimizecpu which disables CPU specific compiler optimizations. * Configure help texts improved. * Added the pwc-10.0.5 version of pwc-ioctl.h. Also good for pwc 10.0.6. * Changing rotate, height and width via xmlrpc no longer affects the running program. This change is done because many internal data structures and memory allocations cannot handle change of image dimensions/size. * Enabled use of leading spaces when changing text_left and text_right via xmlrpc by using quotation marks if the value starts with a leading space. * Speed optimizations for dilate and labelling code. * Significant speed improvement in the motion detection algorithm. * Motion images are now gray scale instead of green. Smartmask is shown in red. * Implemented FreeBSD auto-detection CPU/ARCH fix. * Removed the never finished prediction feature. * Implemented a major improvement of noise_tune. * Implemented ffmpeg-0.4.9 support. * Default for option 'ffmpeg_video_codec' is now mpeg4. mpeg1 is now only supported with the old ffmpeg-0.4.8. * Option 'output_normal' value set to 'first' makes Motion only save a jpeg from the first motion detected picture frame in an event. * Implemented Streaming Netcam Without Curl which enables connecting to network cameras both with single jpeg frame mode and streaming mjpeg mode. This enables much higher framerates with Netcams. * Corrected a small error in the usage help text * Improved the help and doc texts for config option night_compensate. * Improved the signal handling of ctrl-C and kill. * Implemented a POSIX compliant SIGCHLD signal handler to avoid floods of warnings and script zombies in some RedHat versions. * Reporting of the changes of noise detection level is now only displayed in the console (daemon off) when the always_changes option is enabled. * Made the code in xmlrpc more correct and robust (handling of select()). * Fixed several bugs in the timelapse feature. Detailed changes for all 3.1.18 snapshot releases since 3.1.17 snap1 * Removed the Berkeley mpeg feature (code commented out) * Implemented a bugfixed version of http://www.lavrsen.dk/twiki/bin/view/Motion/BrightnessContrastPatch Released as snapshot for developers to merge other patches. The snap1 is not recommended for normal use. snap2 * Improved the Makefile with automatic check of dependencies and nicer output for the user. http://www.lavrsen.dk/twiki/bin/view/Motion/MakefileWithAutoDependencies * Implemented first phase of the rotate patch. Need to fix the storage method for image height and width http://www.lavrsen.dk/twiki/bin/view/Motion/RotatePatch snap3 * Implemented phase 2 of the rotate patch * Added brightness patch options to motion-dist.conf snap4 * Added the new smart mask feature. It is working but it is still under development. It currently outputs an extra smart mask timelapse movie when the normal timelapse is enabled. This will be removed in the final version. http://www.lavrsen.dk/twiki/bin/view/Motion/PatchSmartMask * Added a new config option --without-optimizecpu which disables the CPU specific compiler optimizations introduced with the rotate phase 2 patch. The purpose of the new option is to enable a packager to build an RPM or deb package which is not tied to a specific CPU type. * Man page updated with the new brightness and smart mask options. * Configure help texts improved. * Added the pwc-10.0.5 version of pwc-ioctl.h. * Changing rotate, height and width via xmlrpc no longer affects the running program. The user can change the options and write them to the config files and then restart motion. This change is done because many internal data structures and memory allocations cannot handle change of image dimensions/size. * Fixed the problem with leading spaces of text_left and text_right getting lost when saving with xmlrpc. For text_left and text_right Motion now puts the string in quotation marks if the value starts with a leading space. http://www.lavrsen.dk/twiki/bin/view/Motion/BugReport2004x10x24x135840 snap5 * Implemented the November 10 update for smartmask * Started resolving some of the signed vs unsigned char problems. There is still much to do here. snap5 is released to make the developers up2date. snap6 * Merged in the DilateNineSpeedPatch http://www.lavrsen.dk/twiki/bin/view/Motion/DilateNineSpeedPatch * Changed a few image char definitions to unsigned char. Still many to fix. snap7 * Implemented the 15-Nov-2004 Smartmask patch which removed the smartmask debugging timelapse code and instead adds the smartmask info to the motion images and jpegs as red areas. Normal motion is shown in black and white (greytones). This concludes Joerg Webers smartmask feature. The patch is now in ReleasedScheduled state for 3.1.18. * Implemented Angel Carpintero's FreeBSD auto-detection CPU/ARCH fix. * Merged in Per Johnsson's DilateFiveSpeedPatch http://www.lavrsen.dk/twiki/bin/view/Motion/DilateFiveSpeedPatch * Removed the prediction feature from the code (commented out for now). * Included fix by Jan X. http://www.lavrsen.dk/twiki/bin/view/Motion/BugReport2004x11x13x202132 snap8 * Implemented an improvement of Smartmask so that the mask is cleared when the smart_mask_speed is set from a non-zero to zero (by Joerg Weber) * Implemented an improvement of noise_tune with smart mask (and probably also in general) (by Joerg Weber) * Improved the picture control function so that cameras are only probed when needed to avoid USB errors. (Kenneth Lavrsen) * Implemented new ffmpeg patch (Per Jönsson) http://www.lavrsen.dk/twiki/bin/view/Motion/FfmpegPatch049 * Implemented new preview patch (Joerg Weber) http://www.lavrsen.dk/twiki/bin/view/Motion/PreviewShotsPatch * Removed commented code from obsolete Berkeley and Prediction features * Implemented labelling speed patch (Per Jönsson) http://www.lavrsen.dk/twiki/bin/view/Motion/LabelingSpeedPatch snap9 * Implemented Streaming Netcam Without Curl which enables connecting to network cameras both with single jpeg frame mode and streaming mjpeg mode. This enables much higher framerates with Netcams. (by Christopher Price and Angel Carpintero). http://www.lavrsen.dk/twiki/bin/view/Motion/StreamingNetcamWithoutCurl * Implemented a significant speed improvement in the motion detection algorithm (by Per Jönsson). http://www.lavrsen.dk/twiki/bin/view/Motion/AlgDiffStandardMmxPatch * Fixed a small bug which caused in jumpy mpeg1 videos with ffmpeg 0.4.8. snap10 * Corrected a small error in the usage help text http://www.lavrsen.dk/twiki/bin/view/Motion/BugReport2005x01x05x174139 * Improved the help text for config option night_compensate in docs, conf.c, motion man pages and config file. http://www.lavrsen.dk/twiki/bin/view/Motion/BugReport2005x01x06x103939 * Improved the Netcam patch (Angel Carpintero) http://www.lavrsen.dk/twiki/pub/Motion/StreamingNetcamWithoutCurl/ (pre2 patch fixes problem with not detecting Content-length and segfaults in netcam) * Improved the signal handling of ctrl-C as suggested by Per Jonsson http://www.lavrsen.dk/twiki/bin/view/Motion/BugReport2005x01x06x181426 * Implemented a POSIX compliant SIGCHLD signal handler as replacement for the traditional signal(SIGCHLD, SIG_IGN) which can cause floods of warnings in some RedHat versions. (Angel Carpintero and Kenneth Lavrsen) http://www.lavrsen.dk/twiki/bin/view/Motion/BugReport2004x10x26x134906 * Changed the reporting of the changes of noise detection level so that it is only displayed in the console (daemon off) when the always_changes option is enabled. (Kenneth Lavrsen) * Changed the ffmpeg>0.4.8 = no mpeg1 gcc warning message so that it is clear to people that it is information and not an error message. snap11 * Changed allocation of despeckle buffer to avoid a segfault when using a netcam where the image is wider than defined in motion.conf width. * The noise tune value displayed in the upper left corner along with number of changed pixels is no longer displayed (was there for debugging). * Improved the Netcam patch (Angel Carpintero) http://www.lavrsen.dk/twiki/pub/Motion/StreamingNetcamWithoutCurl/ (pre3 reconnection feature added) * Changed the SIGCHLD handler introduced in snap10 so that it is a shorter and faster function. Disabled this handler in the xmlrpc thread as this caused unnecessary loops of cpu cycles. Additionally made the code in xmlrpc more correct and robust (handling of select()) (Kenneth Lavrsen) * Fixed a bug in the timelapse feature. Both the rollover events of the timelapse video and timelapse shots could be missed if the CPU load was very high or the time was changes by ntp. Motion will now catch up a few seconds later if this happens. Also fixed the code for monthly rollover (Kenneth Lavrsen). http://www.lavrsen.dk/twiki/bin/view/Motion/BugReport2005x01x23x133554 Release * Fixed a bug in the timelapse feature. Both the rollover events of the timelapse video and timelapse shots could be missed if the CPU load was very high or the time was changes by ntp. Motion will now catch up a few seconds later if this happens. Also fixed the code for monthly rollover (Kenneth Lavrsen). http://www.lavrsen.dk/twiki/bin/view/Motion/BugReport2005x01x23x133554 * Small improvement in timelapse feature so that an image is added when the new mpeg is created and not waiting till the following timelapse (Kenneth Lavrsen). * Small improvement so that the timelapse rollover happens on the hour and not one timelapse past the hour (Kenneth Lavrsen). 3.1.17 Bugfix release snap1 * Removed annoying debug syslog message (input: #) * Implemented Peter Ilin's patch for handling vloopback pipes better when Motion receives SIGTERM or SIGHUB. * Implemented fix for compiling errors when building the FreeBSD version without bktr support. (http://www.lavrsen.dk/twiki/bin/view/Motion/FreeBSDFixCompile) * Commented out many unnecessary syslog debug only messages. The commented out code was first patched by Mike Lees patch related to syslog causing instability and hanging motion processes. (http://www.lavrsen.dk/twiki/bin/view/Motion/SyslogEventPatch). * Included Kalle Andersson's patch that ensures that Motion detaches from the stdin and stout devices so that a secure shell that was used to start Motion in daemon mode does not hang when you exit the shell. (http://www.lavrsen.dk/twiki/bin/view/Motion/DaemonDetachFromSTDIO) snap2 * Implemented a new lightswitch feature so that is now triggers lightswitch detected based on the percentage of pixels set by the lightswitch option which is now an integer instead of a boolean. When lightswitch is detected motion skips 5 frames to allow camera to settle. * Fixed a bug in the autobrightness function. * Fixed a bug in netcam_start() - wrong imgs.size calculation Release * Swapped width and height parameters in some functions. This has no influence on program execution. Just a cosmetic change. 3.1.16 Bugfix release snap1 * Fixed a configure error related to xmlrpc. * Fixed a bug in the SQL code related to file type. Release * Fixed a segfault problem in alg.c related to the locate feature. * Made motion more robust to whitespace in its config files. It now accepts CR LF (DOS/Windows) and whitespace only lines no longer gives warning messages in syslog. Also cleaned up the conf.c function structure a little bit. 3.1.15 Summary of changes from 3.1.14 to 3.1.15. New features: * ffmpeg now supports mpeg4 and msmpeg4 in addition to mpeg1. Timelapse mpegs are always made with mpeg1 because this allows appending to existing mpeg when motion or timelapse is restarted. This also meant a change of the configure option --with-libavcodec to --with-ffmpeg which now needs to point to the parent directory that holds libraries. * configure has been significantly improved so that most people can simply run ./configure, make and make install with no parameters and all libraries should be detected automatically if they are installed like in most distributions. * rotation feature added which allows the camera to be mounted upside down or in portrait. * SQL (Postgres and MySQL) table format has been changed. The time related fields such as minute, hour, day, month and year has been replaced by a timestamp field called 'time_stamp'. Additionally a field called 'frame' has been added so that each file can be correctly sorted based on time_stamp and frame (picture frame number within one second). An additional field called 'text_left' stores the displayed text given by config option 'text_left'. And a field 'camera' has been added which stores the thread number. * The %v (event) prefix has been removed from the default filename for timelapse mpegs. It makes little sense to have the current event number as part of the timelapse filename as default. * A new feature called 'labeling' was added which is a great enhancement to the motion detection algorithm. It ensures that only the largest area of movement is included in the detection and it prevents noise and wind from making false detection. It should also make tracking work better. * Angel Carpintero ported motion and it's main features to freeBSD. The freeBSD is still very much beta and because of limited access to hardware we need more people to test the various features. * Motion is now also released as an RPM with both mysql, postgres, libcurl and ffmpeg support. Bugfixes: * Fixed the problem with default strings being written to thread config files when using the XMLRPC command motion.conf.write. * Implemented improvement of vid_putpipe so that Motion does not spend time writing to a vloopback device which is not there. * Introduced reporting to syslog of writing to vloopback fails. * Memory clean-up improvements when Motion exits normally. * Fixed a small bug related to the filename given for onffmpegclose. * Provided more improvements of error handling. * Added additional error reporting to console. 3.1.15 Snapshot releases snap1 * Fixed the problem with default strings being written to thread config files when using the XMLRPC command motion.conf.write. snap2 * Implemented Ryan Ayers improvement of vid_putpipe so that Motion does not spend time writing to a vloopback device which is not there. Also introduced reporting to syslog of writing to vloopback fails. * Ryan Ayers improved configure's ability to find custom installations of ffmpeg. * Ryan Ayers provided misc. cosmetic changes in the code. * Ryan Ayers rewrote the ffmpeg functions completely added support for new codecs/formats mpeg4 and msmpeg4. mpeg1 was improved also. snap3 * Implemented Ryan Ayers simplified ffmpeg patch where 10 ffmpeg functions are reduced to 5. The memory leak related to an unused filehandle has been resolved. * Kenneth Lavrsen solved the timelapse related .mpeg.mpeg filename error. * Kenneth Lavrsen removed the memory leak in ffmpeg.c related to the use of strdup without a free. snap4 * Implemented Ryan Ayers snap3 based ffmpeg patch that cleans up the code significantly, forces timelapse. The list of improvements: * Forces timelapse to mpeg1 for the time being. * Removes FILE* f declaration in ffmpeg.h since we no longer need it. * Removes all picture_buf references. This was carried over from output_example.c in ffmpeg-0.4.8. However, we don't need it. That is allocating space for picture->data, but motion already takes care of this for us with the newimg variable. * Removed some old commented code ... tmpfilename, picture_buf stuff. * Included Angel Carpintero's memory clean-up improvements when Motion exits normally. snap5 * Added Per Jönsson's rotate feature. When set to non-zero some extra CPU time is used for the rotation. * Kenneth Lavrsen changed the ffmpeg code so that mpeg1 files are created using the libavcodec method and mpeg4 and msmpeg4 are created using the new libavframe method in ffmpeg. * Kenneth Lavrsen added seconds and frame fields to the database feature. This means that users must add these two fields to the table "security" in existing databases when upgrading to 3.1.15. * Kenneth Lavrsen removed the %v (event) prefix from the default filename for timelapse mpegs. It makes little sense to have the current event number as part of the timelapse filename as default. snap6 * Kenneth Lavrsen fixed a small bug related to the filename given for onffmpegclose. * Joerg Webers added the new labeling motion detection feature. * Angel Carpintero provided more improvements of error handling. snap7 * Kenneth Lavrsen changed the configure option --with-libavcodec to * --with-ffmpeg and updated Guide and man pages and text in code and config file to match the new shared library way of using ffmpeg * Angel Carpintero ported motion and it's main features to freeBSD. The freeBSD is still very much beta and because of limited access to hardware we need more people to test the various features. * Angel Carpintero created an updated specs file that enables Kenneth to build RPMs of Motion. snap8 * Kenneth Lavrsen added the new fields to the SQL security table camera (thread number), text (text_left) and time (timestamp). * Angel Carpintero improved error handling for the webcam functions. Release * Kenneth Lavrsen simplified the sql functions (1 instead of 3) and ensured that the text field is not assigned when text_left is an empty string. This allows for the field to be auto defaulted. * Added additional error reporting to console. 3.1.14 2004 May 31 * Included Ian McConnell's fix for snapshots when using the "lastsnap" filename. * Fixed the bug in advanced filename and text feature when event numbers go higher than 99. * Included Angel Carpintero's improvement of configure reporting of missing shared libraries (Kenneth Lavrsen improved it a little further). * Included Ian McConnell's timelapse close mpeg file when set to zero patch. * Changed motion-control to make a proper output from motion.conf.list. * Renamed ffmpeg_timelaps to ffmpeg_timelapse (we change now or never) * Corrected man page (\n). * Added setting access rights to 644 (755 for configure) when doing make dist. * Small improvement on xmlrpc-api.html document. * Included Angel Carpintero's fix for building motion without ffmpeg (missing #ifdef round newly added ffmpeg timelapse code) * Fixed missing init of viddev.frequency causing VIDIOCGCHAN errors. * Included Angel Carpintero's snap2 based patch for improving configure. XML-RPC changes of threshold and noise_level are now being used as long as threshold_tune and noise_level are not enabled. * Enabled the round robin feature to also work by changing frequency on the same device and same input. * Fixed the pre_capture feature so that it also stores the jpegs properly. * Fixed the ffmpeg_timelapse feature so that the calculated time is correct and the current image is used instead of an old image from position 0 in the pre_capture ring buffer. * Fixed ffmpeg routines so that also graytone images can be pre_captured and used with ffmpeg_timelapse. * Fixed the position of the incrementing of shots in the motion_loop so that it is correct before any functions use it. * Added quite many comments to the code to make it easier to maintain (more comments will be added). * Removed some old debugging printf's that were displayed in non-quiet mode. * Changed to snapshot feature from being alarm driven to being timer driven. This means that each thread can have its own interval value. The XML-RPC motion.action.snapshot still works. The SIGALRM method has been changed so that all thread that have the snapshot_interval non zero will take a snapshot when being signaled with SIGALRM. A negative value for snapshot_interval will activate the SIGALRM trigger but not the timing interval. * Implemented ffmpeg_timelapse_mode feature by James A. Russo. * Implemented RH (sysV) and Debian type control scripts for /etc/init.d by Angel Carpintero. * Implemented enhanced SQL features by James A. Russo. This adds logging of mpeg and prediction events to MySQL/PostgreSQL. James patch also replaced the mime file types by a more refined filetype scheme that allows more refined control for SQL and other future control. * Kenneth Lavrsen changed the enhanced SQL config from single sql_mask option to 5 sql_log_ options for more user friendly control. * Implemented Daniel Sterlings minimum_motion_frames feature. * Plugged a memory leak in the pre_capture feature. * Changed the behaviour of onsave back to original mode where also snapshots causes onsave command to be run. * Fixed a bug in frequency setting of V4L device. * Renamed snapshots_interval and snapshots_filename to snapshot_interval and snapshot_filename. * Changed the webcam_port value to 0 in motion-dist.conf to avoid that people get segmentation faults when having 2 or more cameras and * webcam_port not set in the thread config files. * Implemented Daniel Sterlings improved handling of config strings. This plugs the memory leak when changing string type options via XML-RPC. * It also makes the memory handling more elegant/optimal and finally it now allows strings to be as long as allowed by the environment variable PATH_MAX. * Kenneth and Daniel added many comments to motion.c and conf.c. * Daniel Sterling made the XMLRPC able to handle errors without crashing. * Daniel Sterling and Kenneth Lavrsen added a feature that checks for two threads having the same webcam_port. If this is the case the last thread gets its webcam disabled and a warning message is written to console and syslog. * Implemented Daniel Sterling's fix for a small calculation error in alg_diff_fast(). * Small improvements in messages sent to console and syslog during startup of Motion. 3.1.13 * Included Ian McConnell's despeckle feature (including extra improvement of the original patch). * Changed the name of motion.conf to motion-dist.conf to avoid make install overwrites your perfectly OK working motion.conf file when you re-install. * Updated the motion.spec.in. Not tested yet. * Included Matthias Kilian configure patch which enables configure to find and use a dynamic library of ffmpegs libavcodec.so . * Included Steffen Haas improved on screen display patch (plus some extra characters including a real space). * Changed the parsing of the motion.conf and thread.conf files so that spaces are now allowed. This also enables using a space in the user text. For XML-RPC you put text in "" if you need spaces. * Changed the XML-RPC function motion.conf.write so that undefined config options gets written into the main motion.conf file with the help line and the option prefixed by a '#'. Example # netcam_url value. * Added Mike Lees onffmpegclose feature which enabled a command to be executed each time a file generated by ffmpeg is closed. * Added Daniel Sterlings night compensate fix. * Added Angel Carpintero's improved configure process which automatically detects presence of xmlrpc-c and ffmpeg and makes the Makefile accordingly. * Included Ian McConnell's flexible on screen display feature and flexible strftime based path names. * Changed conf.c so that xml-rpc command motion.conf.write creates a much more user friendly motion.conf file. * Modified Ian's on screen display putting back the config parameter (draw)text_changes. If enabled the number of changed pixes are shown in the upper right corner of the image. * Removed the snap_override feature and reduced the oldlayout to an Berkeley mpeg_encode feature only renaming it to berkeley_single_directory. Instead the flexible filename feature now has oldlayout as default and the "new" directory layout specified in the motion.conf file. * Motion.conf sequency re-arranged so the important things comes first. * Changed names of many options to be more user friendly. * Renamed the options for displayed text to text_right, text_left and text_changes. * Change the parsing of config files so that the argument can be in quotation marks (" or ') allowing leading spaces for the text_left and text_right options. This means that you can place the text anywhere on the picture by using spaces and new lines \n. 3.1.12 * Removed vid_keepalive * Added reentrant warning to codestyle answer in FAQ. * Rewrite of PWC tracking code. * Tracking is inactive by default. * Motion-control action.quit fix. * Netcam with mask fixed. * Added tracking options to xmlrpc interface. * Ignore SIGPIPE (crashes webcam code). * Changed fast algorithm to imgs.size/10000 steps. * Renamed prerecord to pre_capture to be more consistent with post_capture. * Redone pre_capture completely. 3.1.12 rc1 * added pre-record. with configparameter n_prerecord one can set the number of frames that should be recorded *before* the motion starts. for this feature to work, you need to set post capture to at the value given for n_prerecord! also: n_prerecord must be at least 1 3.1.11 * found 2 memory-leaks (two 'FILE *' were not closed) in the webcam-interface * started working on support for logitech sphere/orbit tracking fixed bug in tracking routines (would sometimes use garbage coordinates) * added max-number-of-frames-limit to the webcaminterface (patch by Jeroen Vreeken) 3.1.10 * added Kenneth's fixes for ffmpeg instability and the problem with the "ioctl(VIDIOCGCHAN): Invalid argument" error * small optimisation of rgb24toyuv420p (about 6% faster) so for certain video-devices things might be a little faster * optimized alg_diff_fast: about 50% faster made it compile again with 2.6.0-test9 * noise tuning is now only done when there's no motion! * noise is resetted to the median of the tuned value and the configured value as soon as no motion is detected * fixed includes for mysql/psql (thanks Felix Finch!) 3.1.9 * motion now logs to syslog instead of stderr, that way it is still possible to see what is going wrong when motion runs as a daemon process. * motion will now exit nicely when memory allocation fails instead of segfaulting * low_cpu now takes the number of frames per second to process when no motion is detected instead of on/off * "quick motion detection" is now only performed when motion is in "idle" mode. * added Kenneth's patch: motion with ffmpeg-0.4.8 now compiles again! * small optimisation: if a file is created, the path is now only recreated when it did not already exist. 3.1.8 is the last version release by Jeroen Vreeken. New maintainers are: Kenneth Lavrsen (http://www.lavrsen.dk/) and Folkert van Heusden (http://www.vanheusden.com/). 3.1.8 Froze 3.1.8 Can't use the same variable name twice in ppm code... 3.1.7 Froze 3.1.7 Added codingstyle answer to faq yuv to rgb conversion for ppm images.

Rewrote locate function, small things (like fish :) don't disturb the locate option anymore. Added break for -B option 1.0 froze 1.0 Went back to alarm for automated snapshots (signals should work with bttv now) Moved usage to conf.c Finished manpage Added check for existing target dir. Moved diff calculation and image_out generation out of main loop, adding other methods is easier this way. Removed sanity check for output formats since someone might want no pictures at all but only warning messages. Make snapshots separately from other pictures. New snapshot names: YYYYMMDDHHMMSS-snapshot Motion images are encoded to mpeg movies to. Made movie file names and counter sane. 0.99-2 froze 0.99-2 Added signal blocking during ioctls, bttv should now continue to work when receiving signals.

Moved image_ref update into diff for loop. *a option does not use alarm anymore, bttv card users can use it to (they just miss the SIGALRM option...) Added picture size settings for read. Moved read back in, after mmap failure motion we fall back to normal reads. Greyscale camera fix Added check for capture failure 0.6 froze 0.6 Fixed stupid typo for execute option (forgot the shift) Added -l option for locating and marking movement Added buffer flush to keep log files up to date 0.5 froze 0.5 Added contrib dir with infra red script Option to always output changes between images Output of motion images configure script 0.4 froze 0.4 Gave the help text a new look. Overall cleanup (moving defines to motion.h) Added -E option for executing external commands 0.3 froze 0.3 New homepage: http://motion.technolust.cx Fixed -t option (target path) Changed from read to mmap for bttv cards Added input and norm selection Added alarm signal handler and snapshot (-a) option (does not work with bttv....) 0.2 froze 0.2 Updated README and TODO Added SMS and mail alert messages Changed file name format to YYYYMMDDHHMMSS-fn.jpg (fn=framenumber) Added deamonize option Cleaned up includes Decaying reference picture added Renamed image1 and image2 to image_ref and image_new 0.1 Initial release motion-28b7cb2a4297c78b9c08c9ce29a648aeb22120d0/CODE_STANDARD000066400000000000000000000155701230376121600217440ustar00rootroot00000000000000Formatting rules for Motion code. Version 2.0 - 15 Jul 2008 Note: To understand them you must view this document with spaces and tabs visible. -------------------- RULE 1 Code is generally indented using 4 spaces Example /* allocate some memory and check if that succeeded or not. If it failed * do some error logging and bail out */ void * mymalloc(size_t nbytes) { void *dummy = malloc(nbytes); if (!dummy) { printf("Could not allocate %llu bytes of memory!\n", (unsigned long long) nbytes); syslog(EMERG, TYPE_ALL, "%s: Could not allocate %llu bytes of memory!", __FUNCTION__, (unsigned long long) nbytes); exit(1); } return dummy; } -------------------- RULE 2 If a line or statement is broken into two lines you will normally want the text in the 2nd line to align with text in the first line. The alignment is done using spaces making the code on the following lines appear in a natural way below the corresponding code above. Use common sense to enhance readability. Example /* allocate some memory and check if that succeeded or not. If it failed * do some error logging and bail out */ void * mymalloc(size_t nbytes) { void *dummy = malloc(nbytes); if (!dummy) { printf("Could not allocate %llu bytes of memory!\n", (unsigned long long) nbytes); syslog(EMERG, TYPE_ALL,"Could not allocate %llu bytes of memory!", __FUNCTION__, (unsigned long long) nbytes); exit(1); } return dummy; } Example cnt->sql_mask = cnt->conf.sql_log_image * (FTYPE_IMAGE + FTYPE_IMAGE_MOTION) + cnt->conf.sql_log_snapshot * FTYPE_IMAGE_SNAPSHOT + cnt->conf.sql_log_mpeg * (FTYPE_MPEG + FTYPE_MPEG_MOTION) + cnt->conf.sql_log_timelapse * FTYPE_MPEG_TIMELAPSE; Example char msg[] = "This is a very long message which we would like to break" "into two lines or more because otherwise the line gets" "too long to read. We align them below each other for readability" -------------------- RULE 3 Never use TABS to align anything. A tab may be 4 positions in one editor and 8 in another. A space is always a space. -------------------- RULE 4 Functions should be written with this syntax. GOOD EXAMPLE /* Comment block * A comment block should be at least one line saying what the function does. * It is better to make several lines explaining what it does, what it takes * for arguments and what it returns. It is a bad idea to try to use tabs to * align text in the comment block */ type function_name(parameters) { declarations declarations statements statements } Do not split the function declaration into two lines. Do not put the '{' after the function declaration. Put it on an empty line right after. Note that this rule is only for functions. BAD EXAMPLE type function_name(parameters) { declarations declarations statements statements } -------------------- RULE 5 Blocks follow K&R. GOOD EXAMPLE if ((picture=fopen(cnt->conf.mask_file, "r"))) { cnt->imgs.mask=get_pgm(cnt, picture, cnt->imgs.width, cnt->imgs.height); fclose(picture); } else { put_fixed_mask(cnt, cnt->conf.mask_file); printf("Hello world\n"); } BAD EXAMPLE (even though Kenneth loves this one personally) if ((picture=fopen(cnt->conf.mask_file, "r"))) { cnt->imgs.mask=get_pgm(cnt, picture, cnt->imgs.width, cnt->imgs.height); fclose(picture); } else { put_fixed_mask(cnt, cnt->conf.mask_file); printf("Hello world\n"); } GOOD EXAMPLE switch (expr) { case ABC: case DEF: statement; break; case UVW: statement; break; default: /* default case */ statement; } BAD EXAMPLE switch (expr) { case ABC: case DEF: statement; break; case UVW: statement; break; default: /* default case */ statement; } -------------------- RULE 6 Whitespace. To ensure that Motion code looks homogeneous and to enhance readability: 1. Do not use a space before a comma 2. Always leave at least one space after a comma 3. Use one space between a block start statement and a '{' 4. Do not use a space between a function name and the '(' 5. Use spaces to enhance readability (a non objective rule but at least think about it) 6. The '*' for pointers should be just before the variable name with no space. GOOD EXAMPLES int function_name(int *par1, int par2, int par3) { if (var1==2 || var2==3) { BAD EXAMPLES int function_name (int * par1 , int par2,int par3){ if (var1==2||var2==3){ -------------------- RULE 7 Comment your code That's worth repeating - PLEASE, PLEASE comment your code. We receive far too much code which is completely uncommented and where variable names are short and say nothing about their function. Use /* This style of comment for permament comments */ or /* * This style of comment for comments which * require more that one line */ Use // this style comments for something you add temporarily while testing and FIXME type comments. It is much easier to spot the temporary comments this way. -------------------- RULE 8 Use variable names that say what the variable is used for. Avoid x,t,vt type variable names. Use names like image, image_buffer, image_height, output_buffer Short names like i and j for loop index variable are a known good practice. Variable and function names are in lower case. Use '_' to separate words. MACROS are in uppercase. camelCase (mix of upper and lower case) is not allowed because it creates too many typos for many two finger typers. -------------------- BEST PRACTICES Not rules, but these suggestions make code easier to read. Use lots of white space and empty lines to group code. For example, large if statements are easier to read when there is an empty line before and after them. Use an empty line before a comment which describes the code lines below. Always use spaces in statements like thisvar->thismember>thisvar->thisothermember (bad) thisvar->thismember > thisvar->thisothermember (good) if (cnt->event_nr==cnt->prev_event||cnt->makemovie) (bad) if (cnt->event_nr == cnt->prev_event || cnt->makemovie) (good) frame_delay=(1000000L/cnt->conf.low_cpu)-frame_delay-elapsedtime; (bad) frame_delay = (1000000L / cnt->conf.low_cpu) - frame_delay - elapsedtime; (good) -------------------- This document can probably be enhanced more as time goes by. Hope it helps developers to understand the ideas. What happens if I do not follow the rules? Your code will probably be accepted, but developers will have to spend a lot of time rewriting the code to follow the standard. If this happens, he may make a less-than-complimentary remark. Please help the developers by at least trying to follow the spirit of this document. We all have our coding preferences, but if Motion is coded in 40 different styles, readability (and at the end quality) will become bad. motion-28b7cb2a4297c78b9c08c9ce29a648aeb22120d0/COPYING000066400000000000000000000430761230376121600210640ustar00rootroot00000000000000 GNU GENERAL PUBLIC LICENSE Version 2, June 1991 Copyright (C) 1989, 1991 Free Software Foundation, Inc. 675 Mass Ave, Cambridge, MA 02139, USA Everyone is permitted to copy and distribute verbatim copies of this license document, but changing it is not allowed. Preamble The licenses for most software are designed to take away your freedom to share and change it. By contrast, the GNU General Public License is intended to guarantee your freedom to share and change free software--to make sure the software is free for all its users. This General Public License applies to most of the Free Software Foundation's software and to any other program whose authors commit to using it. (Some other Free Software Foundation software is covered by the GNU Library General Public License instead.) You can apply it to your programs, too. When we speak of free software, we are referring to freedom, not price. Our General Public Licenses are designed to make sure that you have the freedom to distribute copies of free software (and charge for this service if you wish), that you receive source code or can get it if you want it, that you can change the software or use pieces of it in new free programs; and that you know you can do these things. To protect your rights, we need to make restrictions that forbid anyone to deny you these rights or to ask you to surrender the rights. These restrictions translate to certain responsibilities for you if you distribute copies of the software, or if you modify it. For example, if you distribute copies of such a program, whether gratis or for a fee, you must give the recipients all the rights that you have. You must make sure that they, too, receive or can get the source code. And you must show them these terms so they know their rights. We protect your rights with two steps: (1) copyright the software, and (2) offer you this license which gives you legal permission to copy, distribute and/or modify the software. Also, for each author's protection and ours, we want to make certain that everyone understands that there is no warranty for this free software. If the software is modified by someone else and passed on, we want its recipients to know that what they have is not the original, so that any problems introduced by others will not reflect on the original authors' reputations. Finally, any free program is threatened constantly by software patents. We wish to avoid the danger that redistributors of a free program will individually obtain patent licenses, in effect making the program proprietary. To prevent this, we have made it clear that any patent must be licensed for everyone's free use or not licensed at all. The precise terms and conditions for copying, distribution and modification follow. GNU GENERAL PUBLIC LICENSE TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION 0. This License applies to any program or other work which contains a notice placed by the copyright holder saying it may be distributed under the terms of this General Public License. The "Program", below, refers to any such program or work, and a "work based on the Program" means either the Program or any derivative work under copyright law: that is to say, a work containing the Program or a portion of it, either verbatim or with modifications and/or translated into another language. (Hereinafter, translation is included without limitation in the term "modification".) Each licensee is addressed as "you". Activities other than copying, distribution and modification are not covered by this License; they are outside its scope. The act of running the Program is not restricted, and the output from the Program is covered only if its contents constitute a work based on the Program (independent of having been made by running the Program). Whether that is true depends on what the Program does. 1. You may copy and distribute verbatim copies of the Program's source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice and disclaimer of warranty; keep intact all the notices that refer to this License and to the absence of any warranty; and give any other recipients of the Program a copy of this License along with the Program. You may charge a fee for the physical act of transferring a copy, and you may at your option offer warranty protection in exchange for a fee. 2. You may modify your copy or copies of the Program or any portion of it, thus forming a work based on the Program, and copy and distribute such modifications or work under the terms of Section 1 above, provided that you also meet all of these conditions: a) You must cause the modified files to carry prominent notices stating that you changed the files and the date of any change. b) You must cause any work that you distribute or publish, that in whole or in part contains or is derived from the Program or any part thereof, to be licensed as a whole at no charge to all third parties under the terms of this License. c) If the modified program normally reads commands interactively when run, you must cause it, when started running for such interactive use in the most ordinary way, to print or display an announcement including an appropriate copyright notice and a notice that there is no warranty (or else, saying that you provide a warranty) and that users may redistribute the program under these conditions, and telling the user how to view a copy of this License. (Exception: if the Program itself is interactive but does not normally print such an announcement, your work based on the Program is not required to print an announcement.) These requirements apply to the modified work as a whole. If identifiable sections of that work are not derived from the Program, and can be reasonably considered independent and separate works in themselves, then this License, and its terms, do not apply to those sections when you distribute them as separate works. But when you distribute the same sections as part of a whole which is a work based on the Program, the distribution of the whole must be on the terms of this License, whose permissions for other licensees extend to the entire whole, and thus to each and every part regardless of who wrote it. Thus, it is not the intent of this section to claim rights or contest your rights to work written entirely by you; rather, the intent is to exercise the right to control the distribution of derivative or collective works based on the Program. In addition, mere aggregation of another work not based on the Program with the Program (or with a work based on the Program) on a volume of a storage or distribution medium does not bring the other work under the scope of this License. 3. You may copy and distribute the Program (or a work based on it, under Section 2) in object code or executable form under the terms of Sections 1 and 2 above provided that you also do one of the following: a) Accompany it with the complete corresponding machine-readable source code, which must be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or, b) Accompany it with a written offer, valid for at least three years, to give any third party, for a charge no more than your cost of physically performing source distribution, a complete machine-readable copy of the corresponding source code, to be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or, c) Accompany it with the information you received as to the offer to distribute corresponding source code. (This alternative is allowed only for noncommercial distribution and only if you received the program in object code or executable form with such an offer, in accord with Subsection b above.) The source code for a work means the preferred form of the work for making modifications to it. For an executable work, complete source code means all the source code for all modules it contains, plus any associated interface definition files, plus the scripts used to control compilation and installation of the executable. However, as a special exception, the source code distributed need not include anything that is normally distributed (in either source or binary form) with the major components (compiler, kernel, and so on) of the operating system on which the executable runs, unless that component itself accompanies the executable. If distribution of executable or object code is made by offering access to copy from a designated place, then offering equivalent access to copy the source code from the same place counts as distribution of the source code, even though third parties are not compelled to copy the source along with the object code. 4. You may not copy, modify, sublicense, or distribute the Program except as expressly provided under this License. Any attempt otherwise to copy, modify, sublicense or distribute the Program is void, and will automatically terminate your rights under this License. However, parties who have received copies, or rights, from you under this License will not have their licenses terminated so long as such parties remain in full compliance. 5. You are not required to accept this License, since you have not signed it. However, nothing else grants you permission to modify or distribute the Program or its derivative works. These actions are prohibited by law if you do not accept this License. Therefore, by modifying or distributing the Program (or any work based on the Program), you indicate your acceptance of this License to do so, and all its terms and conditions for copying, distributing or modifying the Program or works based on it. 6. Each time you redistribute the Program (or any work based on the Program), the recipient automatically receives a license from the original licensor to copy, distribute or modify the Program subject to these terms and conditions. You may not impose any further restrictions on the recipients' exercise of the rights granted herein. You are not responsible for enforcing compliance by third parties to this License. 7. If, as a consequence of a court judgment or allegation of patent infringement or for any other reason (not limited to patent issues), conditions are imposed on you (whether by court order, agreement or otherwise) that contradict the conditions of this License, they do not excuse you from the conditions of this License. If you cannot distribute so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may not distribute the Program at all. For example, if a patent license would not permit royalty-free redistribution of the Program by all those who receive copies directly or indirectly through you, then the only way you could satisfy both it and this License would be to refrain entirely from distribution of the Program. If any portion of this section is held invalid or unenforceable under any particular circumstance, the balance of the section is intended to apply and the section as a whole is intended to apply in other circumstances. It is not the purpose of this section to induce you to infringe any patents or other property right claims or to contest validity of any such claims; this section has the sole purpose of protecting the integrity of the free software distribution system, which is implemented by public license practices. Many people have made generous contributions to the wide range of software distributed through that system in reliance on consistent application of that system; it is up to the author/donor to decide if he or she is willing to distribute software through any other system and a licensee cannot impose that choice. This section is intended to make thoroughly clear what is believed to be a consequence of the rest of this License. 8. If the distribution and/or use of the Program is restricted in certain countries either by patents or by copyrighted interfaces, the original copyright holder who places the Program under this License may add an explicit geographical distribution limitation excluding those countries, so that distribution is permitted only in or among countries not thus excluded. In such case, this License incorporates the limitation as if written in the body of this License. 9. The Free Software Foundation may publish revised and/or new versions of the General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns. Each version is given a distinguishing version number. If the Program specifies a version number of this License which applies to it and "any later version", you have the option of following the terms and conditions either of that version or of any later version published by the Free Software Foundation. If the Program does not specify a version number of this License, you may choose any version ever published by the Free Software Foundation. 10. If you wish to incorporate parts of the Program into other free programs whose distribution conditions are different, write to the author to ask for permission. For software which is copyrighted by the Free Software Foundation, write to the Free Software Foundation; we sometimes make exceptions for this. Our decision will be guided by the two goals of preserving the free status of all derivatives of our free software and of promoting the sharing and reuse of software generally. NO WARRANTY 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. END OF TERMS AND CONDITIONS Appendix: How to Apply These Terms to Your New Programs If you develop a new program, and you want it to be of the greatest possible use to the public, the best way to achieve this is to make it free software which everyone can redistribute and change under these terms. To do so, attach the following notices to the program. It is safest to attach them to the start of each source file to most effectively convey the exclusion of warranty; and each file should have at least the "copyright" line and a pointer to where the full notice is found. Copyright (C) 19yy This program is free software; you can redistribute it and/or modify it under the terms of the GNU General Public License as published by the Free Software Foundation; either version 2 of the License, or (at your option) any later version. This program is distributed in the hope that it will be useful, but WITHOUT ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU General Public License for more details. You should have received a copy of the GNU General Public License along with this program; if not, write to the Free Software Foundation, Inc., 675 Mass Ave, Cambridge, MA 02139, USA. Also add information on how to contact you by electronic and paper mail. If the program is interactive, make it output a short notice like this when it starts in an interactive mode: Gnomovision version 69, Copyright (C) 19yy name of author Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'. This is free software, and you are welcome to redistribute it under certain conditions; type `show c' for details. The hypothetical commands `show w' and `show c' should show the appropriate parts of the General Public License. Of course, the commands you use may be called something other than `show w' and `show c'; they could even be mouse-clicks or menu items--whatever suits your program. You should also get your employer (if you work as a programmer) or your school, if any, to sign a "copyright disclaimer" for the program, if necessary. Here is a sample; alter the names: Yoyodyne, Inc., hereby disclaims all copyright interest in the program `Gnomovision' (which makes passes at compilers) written by James Hacker. , 1 April 1989 Ty Coon, President of Vice This General Public License does not permit incorporating your program into proprietary programs. If your program is a subroutine library, you may consider it more useful to permit linking proprietary applications with the library. If this is what you want to do, use the GNU Library General Public License instead of this License. motion-28b7cb2a4297c78b9c08c9ce29a648aeb22120d0/CREDITS000066400000000000000000002425521230376121600210510ustar00rootroot00000000000000Thanks go to: Jeroen Vreeken *** Original writer of this great program! *** From 3.1.12 these contributions: * Rewrite of PWC tracking code. * Motion-control action.quit fix. * Added tracking options to xmlrpc interface. * Ignore SIGPIPE (crashes webcam code). * Changed fast algorithm to imgs.size/10000 steps. * Renamed prerecord to pre_capture to be more consistent with post_capture. * Redone pre_capture completely. Kalle Andersson * Created a patch that ensures that Motion detaches from the stdin and stout devices so that a secure shell that was used to start Motion in daemon mode does not hang when you exit the shell. Ryan Ayers * Implemented improvement of vid_putpipe so that Motion does not spend time writing to a vloopback device which is not there. Also introduced reporting to syslog of writing to vloopback fails. * Improved configure's ability to find custom installations of ffmpeg. * Misc. cosmetic changes in the code. * Rewrote the ffmpeg functions completely added support for new codecs/formats mpeg4 and msmpeg4. mpeg1 was improved also. * Misc. improvement of the mpeg4 feature and new ffmpeg code.

Bug was introduced in snap4 (Angel Carpintero, Kenneth Lavrsen). * Implemented the libjpeg-mmx patch. Installing the MMX version of libjpeg can increase performance. Especially for machines with very little CPU power. It only modifies the configure script. If you do not have the libjpeg-mmx the configure script with ignore this and use the standard libjpeg. Note that RPMS will be built without this (Peter Holik and Angel Carpintero). http://www.lavrsen.dk/twiki/bin/view/Motion/LibJpegMmx * Fixed memory leak in webhttpd related to use of strdup. * Error Logging Enhancement Patch v 1.3 including: * Populate the motion_log to the whole motion source code. * Fixed FreeBSD compilation. * Added the possibility to pass NULL as struct context * * Removed unused errno variables. * Fixed errno in rotate.c , set to 0. * Fixed some errno flags in webhttpd.c and motion.c * Fixed a bug when not motion.conf is found * Removed printf from all files * Fixed the conf_list[] index in motion.c * http://www.lavrsen.dk/twiki/bin/view/Motion/ErrorLoggingEnhancementPatch * http-control: Fixed segfault when motion is restarted from command line ( kill -s 1 pid_motion ).

This makes motion a lot more stable. Michael Finsterbusch * Add authentication methods 'Basic Authentication' and 'Digest Authentication' to the "Live Stream Server". http://www.lavrsen.dk/foswiki/bin/view/Motion/MotionStreamAuthPatch Mark Feenstra * Fix zombies on OpenBSD. http://www.lavrsen.dk/foswiki/bin/view/Motion/BugReport2010x04x28x054348 Miguel Freitas * Came up with the round robing idea. Aaron Gage * Pointed me to the vid_mmap/int problem when calling SYNC in video.c Giacomo Graziosi * Sqlite3 support http://www.lavrsen.dk/twiki/bin/view/Motion/SQLite3Patch Christophe Grenier * Fixed some file descriptor leaks in webcam.c and netcam.c. * Renamed the top level global context structure to cnt_list so it can be reached from child threads and by above mentioned close_anything_open() * Contributed with most of the code for new function in event.c close_anything_open() which is called from send_sms, send_mail and exec_command in order to prevent file descriptor and open sockets to be inherited by the shell causing freezing and instability. Code contributed by Christophe Grenier, Christopher Price and Kenneth Lavrsen. * Change the working directory to / in daemon mode. This way you don't have to kill motion to umount the partition from where you start it. http://www.lavrsen.dk/twiki/bin/view/Motion/ChdirNetCamWgetPatch * In netcam-wget header_get() didn't always in add a \0 string terminator. This was fixed. http://www.lavrsen.dk/twiki/bin/view/Motion/ChdirNetCamWgetPatch * Made a pthread fix. http://www.lavrsen.dk/twiki/bin/view/Motion/PthreadFixPatch * Implemented the conversion of signal to sigaction which should be more thread safe.

Gerrit Hannaert * Fix v4l2_palette http://www.lavrsen.dk/twiki/bin/view/Motion/UvcvideoMjpegPatch Peter Holik * Netcam First Header patch. If an error with jpeg decompression occurred at connecting to a mjpeg streaming webcam, this patch skips this jpeg and tries to decompress next jpeg up to MAX_HEADER_RETRIES (20). http://www.lavrsen.dk/twiki/bin/view/Motion/NetcamFirstHeader * Small improvement in framerate accuracy. http://www.lavrsen.dk/twiki/bin/view/Motion/FramerateAdjust * Implemented a modified version of the WebcamCompressInMemory so that Motion no longer uses the tmpfile() function for buffering the frames of the mjpeg stream. http://www.lavrsen.dk/twiki/bin/view/Motion/WebcamCompressInMemory * Implemented the libjpeg-mmx patch. Installing the MMX version of libjpeg can increase performance. Especially for machines with very little CPU power. It only modifies the configure script. If you do not have the libjpeg-mmx the configure script with ignore this and use the standard libjpeg. Note that RPMS will be built without this (Peter Holik and Angel Carpintero). http://www.lavrsen.dk/twiki/bin/view/Motion/LibJpegMmx * Small code cleanup in webcam.c and picture.c and .h for the webcam code (Peter Holik and Kenneth Lavrsen). * Small speed optimization in the creation of reference frame. * Removed all warnings originating from the motion sources when running ./configure --with-developer-flags. The modifications were done by the following people: Peter Holik, Bill Brack, Angel Carpintero and Kenneth Lavrsen. http://www.lavrsen.dk/twiki/bin/view/Motion/ReduceWarningsPatch * Implemented a speed-up patch of the draw text feature. http://www.lavrsen.dk/twiki/bin/view/Motion/DrawTextspeedup * http control: selectbox instead of a textfield for changing boolean configs (Peter Holik and Angel Carpintero). http://www.lavrsen.dk/twiki/bin/view/Motion/WebhttpEnhancements. * Introduced check for device image size being a multiple of 16. http://www.lavrsen.dk/twiki/bin/view/Motion/NetcamModulo16Patch * Fixed netcamera bug related to separating frames in an mjpeg stream. From mailing list 23 Dec 2005. * Avoid open file descriptor when connecting to network cameras fails http://www.lavrsen.dk/twiki/bin/view/Motion/AvoidOpenfiledescriptors * Fix Segfault on reload or quit for vloopback (maybe other v4l1 devices too) http://www.lavrsen.dk/foswiki/bin/view/Motion/BugReport2009x06x17x090603 * Fix warning for __USE_GNU redefined http://www.lavrsen.dk/foswiki/bin/view/Motion/BugReport2009x06x17x122137 * Use static memory allocation in ffmpeg_deinterlace() http://www.lavrsen.dk/foswiki/bin/view/Motion/FfmpegDeinterlaceStatic * Atom optimizacion in configure.in http://www.lavrsen.dk/foswiki/bin/view/Motion/AtomOptimizations Wesley Hosking * For pointing me to the absence of a frame length check using read for capturing Peter Ilin * Patch for handling vloopback pipes better when Motion receives SIGTERM or SIGHUB Per Jönsson * Added the rotate feature. * Improved the Makefile with automatic check of dependencies and nicer output for the user. http://www.lavrsen.dk/twiki/bin/view/Motion/MakefileWithAutoDependencies * Improved rotate feature (speed) http://www.lavrsen.dk/twiki/bin/view/Motion/RotatePatch * Implemented new ffmpeg patch http://www.lavrsen.dk/twiki/bin/view/Motion/FfmpegPatch049 * Implemented labelling speed patch http://www.lavrsen.dk/twiki/bin/view/Motion/LabelingSpeedPatch * Improved the signal handling of ctrl-C http://www.lavrsen.dk/twiki/bin/view/Motion/BugReport2005x01x06x181426 * Fixed the ffmpeg code so that Motion also compiles against libavcodec build 4754 or later. * Fixed a bug in the autobrightness algorithm. * RotateBswapFix Patch v 2 including: * cleanup in code comments * fix for __bswap_32 macro collision * fixed bug where initialization would be incomplete for invalid degrees of rotation * now uses motion_log for error reporting http://www.lavrsen.dk/twiki/bin/view/Motion/RotateBswapFix * Implemented Threadnr in TLS (thread-local storage)patch. It puts the thread number into TLS and modifies motion_log() so that we do not have to drag the cnt struct around just to be able to print the thread number in the log and on the console. (Per Jönsson with additional removal of unused cnt by Kenneth Lavrsen). http://www.lavrsen.dk/twiki/bin/view/Motion/ThreadNrTlsPatch * Simplified rotation code based on the fact that images must have dimensions that are a multiple of 16. http://www.lavrsen.dk/twiki/bin/view/Motion/RotateSimplificationPatch Mike Kenney * Implemented a fix for the rare problem where some experienced that the move file names would only consist of the extension .mpg or .avi with no name in front. The root cause was the use of sprintf for appending to strings. (Mike Kenney and Kenneth Lavrsen) http://www.lavrsen.dk/twiki/bin/view/Motion/SupportQuestion2005x09x05x133031 http://www.lavrsen.dk/twiki/bin/view/Motion/SupportQuestion2006x06x19x174238 Rafis Khayrullin * Fix memory management in ffmpeg.c http://www.lavrsen.dk/twiki/bin/view/Motion/BugReport2006x12x19x062432 Matthias Kilian * Configure patch which enables configure to find and use a dynamic library of ffmpegs libavcodec.so Daniel Ladd * Fixed a bug in the rgb2yuv420p function. http://www.lavrsen.dk/twiki/bin/view/Motion/BugReport2005x03x30x011107 Kenneth Lavrsen (Currently project managing Motion) * Wrote the excellent Motion Guide. (Jeroen wrote this :-) ) * Fixed low_cpu to check for a 1sec. maximum wait. * Updated manpage for 3.0.0 * New usertext additions to draw.c * Fixed ffmpeg compatibility for ffmpeg 0.4.8 * Fixed ffmpeg instability problem * Fixed "ioctl(VIDIOCGCHAN): Invalid argument" error * Changed motion.conf to motion-dist.conf. * Changed the parsing of the motion.conf and thread.conf files so that spaces are now allowed. * Changed the parsing of the user defined on screen display text so that you can enclose a string in "" both in config file and using the XML-RPC interface. Ie. you can use spaces in the text. * Changed conf.c so that xml-rpc command motion.conf.write creates a much more user friendly motion.conf file. * Modified Ian's on screen display putting back the config parameter drawtext_changes. If enabled the number of changed pixes are shown in the upper right corner of the image. * Removed the snap_override feature and reduced the oldlayout to an Berkeley mpeg_encode feature only renaming it to berkeley_single_directory. Instead the flexible filename feature now has oldlayout as default and the "new" directory layout specified in the motion.conf file. * Motion.conf sequency re-arranged so the important things comes first. * Changed names of many options to be more user friendly. * Renamed the options for displayed text to text_right, text_left and text_changes. * Change the parsing of config files so that the argument can be in quotation marks (" or ') allowing leading spaces for the text_left and text_right options. This means that you can place the text anywhere on the picture by using spaces and new lines \n. * Fixed problem with strftime based names with event number %v when event numbers were higher than 99. * Changed motion-control to make a proper output from motion.conf.list. * Renamed ffmpeg_timelaps to ffmpeg_timelapse (we change now or never) * Corrected man page (\n) (thanks Daniel). * Added setting access rights to 644 (755 for configure) when doing make dist. * Small improvement on xmlrpc-api.html document. * Fixed missing init of viddev.frequency causing VIDIOCGCHAN errors. XML-RPC changes of threshold and noise_level are now being used as long as threshold_tune and noise_level are not enabled. * Enabled the round robin feature to also work by changing frequency on the same device and same input. * Fixed the pre_capture feature so that it also stores the jpegs properly. * Fixed the ffmpeg_timelapse feature so that the calculated time is correct and the current image is used instead of an old image from position 0 in the pre_capture ring buffer. * Fixed ffmpeg routines so that also graytone images can be pre_captured and used with ffmpeg_timelapse. * Fixed the position of the incrementing of shots in the motion_loop so that it is correct before any functions use it. * Added quite many comments to the code to make it easier to maintain (more comments will be added). * Removed some old debugging printf's that were displayed in non-quiet mode. * Changed to snapshot feature from being alarm driven to being timer driven. This means that each thread can have its own interval value. The XML-RPC motion.action.snapshot still works. The SIGALRM method has been changed so that all thread that have the snapshot_interval non zero will take a snapshot when being signaled with SIGALRM. A negative value for snapshot_interval will activate the SIGALRM trigger but not the timing interval. * Kenneth Lavrsen changed the enhanced SQL config from single sql_mask option to 5 sel_log_ options for more user friendly control. * Changed the behaviour of onsave back to original mode where also snapshots causes onsave command to be run. * Fixed a bug in frequency setting of V4L device. * A few lines of code for Dan's improved handling of config strings. * Daniel Sterling and Kenneth Lavrsen added a feature that checks for two threads having the same webcam_port. If this is the case the last thread gets its webcam disabled and a warning message is written to console and syslog. * Small improvements in messages sent to console and syslog during startup of Motion. * Fixed the problem with default strings being written to thread config files when using the XMLRPC command motion.conf.write. * Fixed memory leaks in new ffmpeg code. * Changed the ffmpeg code so that mpeg1 files are created using the libavcodec method and mpeg4 and msmpeg4 are created using the new libavframe method in ffmpeg. * Added seconds and frame fields to the database feature. * Fixed a small bug related to the filename given for onffmpegclose. changed the configure option --with-libavcodec to --with-ffmpeg and updated Guide and man pages and text in code and config file to match the new shared library way of using ffmpeg. * Added the new fields to the SQL security table camera (thread number), text (text_left) and time (timestamp). * Simplified the sql functions (1 instead of 3) and ensured that the text field is not assigned when text_left is an empty string. This allows for the field to be auto defaulted. * Added additional error reporting to console. * Implemented a new lightswitch feature so that is now triggers lightswitch detected based on the percentage of pixels set by the lightswitch option which is now an integer instead of a boolean. When lightswitch is detected motion skips 5 frames to allow camera to settle. * Fixed a bug in the autobrightness function. * Fixed a bug in netcam_start() - wrong imgs.size calculation. * Removed the obsolete Berkeley mpeg feature. * Corrected a small error in the usage help text http://www.lavrsen.dk/twiki/bin/view/Motion/BugReport2005x01x05x174139 * Improved the help text for config option night_compensate in docs, conf.c, motion man pages and config file. http://www.lavrsen.dk/twiki/bin/view/Motion/BugReport2005x01x06x103939 * Implemented a POSIX compliant SIGCHLD signal handler as replacement for the traditional signal(SIGCHLD, SIG_IGN) which can cause floods of warnings in some RedHat versions. (with Angel Carpintero) http://www.lavrsen.dk/twiki/bin/view/Motion/BugReport2004x10x26x134906 * Changed the reporting of the changes of noise detection level so that it is only displayed in the console (daemon off) when the always_changes option is enabled. (Kenneth Lavrsen) * Changed the ffmpeg>0.4.8 = no mpeg1 gcc warning message so that it is clear to people that it is information and not an error message. * Changed allocation of despeckle buffer to avoid a segfault when using a netcam where the image is wider than defined in motion.conf width. * The noise tune value displayed in the upper left corner along with number of changed pixels is no longer displayed (was there for debugging). * Changed the SIGCHLD handler introduced in snap10 so that it is a shorter and faster function. Disabled this handler in the xmlrpc thread as this caused unnecessary loops of cpu cycles. Additionally made the code in xmlrpc more correct and robust (handling of select()) (Kenneth Lavrsen) * Fixed a bug in the timelapse feature. Both the rollover events of the timelapse video and timelapse shots could be missed if the CPU load was very high or the time was changes by ntp. Motion will now catch up a few seconds later if this happens. Also fixed the code for monthly rollover. (Kenneth Lavrsen) http://www.lavrsen.dk/twiki/bin/view/Motion/BugReport2005x01x23x133554 * Small improvement in timelapse feature so that an image is added when the new mpeg is created and not waiting till the following timelapse (Kenneth Lavrsen). * Small improvement so that the rollover happens on the hour and not one timelapse past the hour (Kenneth Lavrsen). * Fixed a bug in noise tune which was most visible at very low light. * Re-arranged many of the const char declarations so that they are always before any statements within a block { }. This is to avoid compiler errors with older but still used gcc versions such as 2.9.5. * Changed the use of %zd to %llu in printf statements of size_t types. This is done to avoid compiler errors with older but still used gcc versions such as 2.95. * Fixed even more gcc 2.95 compiler errors (declarations not at beginning of block). * Removed a gcc 2.95 compiler warning (netcam.c:1036: warning: variable `pic' might be clobbered by `longjmp' or `vfork'). * The values for cnt->locate and cnt->new_img are now #defines in motion.h to enhance code readability. * The setting of sql_mask is now only done once per second to save CPU power. * Adding checking for conflict between control port and webcam port. Webcam port for a thread is disabled if it is set to the same value as the control port. * Added "motion-http:" prefix to error messages from the http control thread. (Kenneth Lavrsen) * Added additional error information when connection to MySQL fails. * Initiate cnt->event_nr to 1 to avoid code related to end of events and long mpeg films to be run during startup of Motion. * Added new function in event.c close_anything_open() which is called from send_sms, send_mail and exec_command in order to prevent file descriptor and open sockets to be inherited by the shell causing freezing and instability. Code contributed by Christophe Grenier, Christopher Price and Kenneth Lavrsen. * Added new context global cnt_list.control_socket_server set by the httpd thread so that the above mentioned close_anything_open() can close open control sockets. * Threw away the file descriptor leak fix from snap 9 because it caused more trouble than it fixed. Removed the close_anything_open() and the cnt_list.control_socket_server field. Replaced it all with a simple piece of code that all server daemons call when started: setsid() followed by for (i=getdtablesize(); i>2; --i) close(i). Dirty and simple. http://www.lavrsen.dk/twiki/bin/view/Motion/BugReport2005x03x21x070534 * Fixed a bug where rate of fetching picture frames was disturned by the signal SIG_CHLD from exec_command programs terminating. The symptom was that the number of post_capture frames became inaccurate and motion in mpegs did not have constant time between frames. * Fixed a bug where motion did not work with gap=1. http://www.lavrsen.dk/twiki/bin/view/Motion/BugReport2005x01x30x073616 * Added the feature gap=0 which now also works. It disables gap completely so that one single mpeg file is created. You can end the event from the remote control interface make movie feature using for example cron. This makes Motion close the mpeg and make a new with event number increased by one. * Improved the http remote control action features so that makemovie and snapshot for thread 0 (all) works on all threads instead of being ignored. * Moved some code in the beginning of the motion_loop to a position later to improve the accuracy of time calculations for the framerate. * Improvements of motion.conf help comments including improvements in new onxxxx options. * Motion Guide refactored completely for 3.2.1 with better web navigation and auto generation of pages. Makefile updated so that the Motion TWiki topic MotionGuideOneLargeDocument is fetched when updating the guide and making releases. * Removed the debug_parameter option which had no use. Programmers can still use it because the code is only commented out. This change required a small update in the code that rewrites motion.conf so that a remote control command to write the config files still adds a text header for the thread section at the end of motion.conf. * Changed the default values for a few options: quiet on, webcam_maxrate 1, threshold_tune off, webcam_quality 50. * Changed some cosmetics in the way motion.conf is written (space after #). * Updated the motion-dist.conf to use default values unless there is a reason not to. * Fixed a bug in the low_cpu feature where cpu load increased instead of decreasing because the framerate calculations were completely wrong. This was an old bug introduced in 3.0.1. http://www.lavrsen.dk/twiki/bin/view/Motion/BugReport2005x04x24x205933 * Improved the auto-brightness algorithm. When auto-brightness is enabled the brightness option becomes a target value for the brightness level. This should also close a bug report. http://www.lavrsen.dk/twiki/bin/view/Motion/BugReport2005x02x26x195358. * Made the http control HTML responses nicer to look at as sources and therefore easier to debug errors. * Code style cleanup of webhttpd.c. * Fixed compatibility problem with Palantir. Fixed by making output more compatible with RFC (\r\n). Original fixes by Roberto Spadim and Angel Carpintero. However this fix made Firefox flicker even more than it normally does. Final fix which works in both Palantir client, Firefox and Cambozola was made by Kenneth Lavrsen. This closes the following bugs: http://www.lavrsen.dk/twiki/bin/view/Motion/BugReport2005x05x02x205307, http://www.lavrsen.dk/twiki/bin/view/Motion/BugReport2005x05x07x042849 * Added new conversion specifiers: %D (diffs), (noise) %K (motion center x), %L (motion center y), %i (locate width x) and %J (locate width y). These changes also required a refactoring of the alg_locate code. This change is part of the implementation of a generic tracking feature and it enables implementing external programs that can perform simple prediction features. http://www.lavrsen.dk/twiki/bin/view/Motion/ExtendReplaceConversionSpecifiersDiscussion http://www.lavrsen.dk/twiki/bin/view/Motion/GenericTrackingPatch * Fixed a bug in switchfilter which caused motion detection to not work when the feature was enabled. * Fix for Unknown content type with lumenera cameras http://www.lavrsen.dk/twiki/bin/view/Motion/BugReport2005x05x06x174416 * Man page updated. It is now semi-autogenerated in the Motion TWiki http://www.lavrsen.dk/twiki/bin/view/Motion/MotionOptionsAlphabeticalManpage * Added two new convertion specifiers: %o for threshold and %Q for number of labels. * Improved the config file description for pre_capture to get people to use small values. * Major code cleanup concerning signedness of chars all over the code to allow compilation with gcc4.0 (like in Fedora Core 4) without any errors or warnings. This will probably require that some of the not yet included patches will have to be fixed because it it code all over the place that has been changed. * Changed the configure script so that /usr/lib64 is also searched for the presence of ffmpeg (should fix the problem with 64 bit machines). * Changed the configure script so that rpms can be made by normal non-root users. * Fixed a bug in the webhttpd code related to pan/tilt. Bug was introduced in snap4 (Angel Carpintero, Kenneth Lavrsen). * Changed all use of localtime to localtime_r which is threadsafe. * Modified the WebcamCompressInMemory patch so that Motion now supports the mjpeg webcam stream while being setup for saving PPM images. http://www.lavrsen.dk/twiki/bin/view/Motion/WebcamCompressInMemory * Major clean-up of code in picture.c and webcam.c so that function names and variable names are less confusing. Also added many comments in picture.c. * Webcam code commented more. * New improved webcam feature. When you set webcam_motion on Motion will now stream at 1 fps instead of none. When motion is detected the webcam stream increases to the limit set in the config file. This change makes the webcam_motion much more interesting. The previous function always ended up with clients timing out. * Small code cleanup in webcam.c and picture.c and .h for the webcam code (Peter Holik and Kenneth Lavrsen) * Small code cleanup in motion.c for the variable holding the number of microseconds since epoch. The old code worked fine but relied on an integer overflow every 71 minutes. (Bill Brack and Kenneth Lavrsen) * Fixed bug related to disabled webcam or duplicate webcam port. Error log accept(): Socket operation on non-socket continuously written to syslog. http://www.lavrsen.dk/twiki/bin/view/Motion/BugReport2005x08x01x150922 * Included a CODE_STANDARD text file to help new developers make patches that are easier to integrate without too much manual editing. * Changed the 5 second missed camera signal timeout to 30 seconds. * Fixed bug where an extra jpeg is saved if you have output_normal=best and you stop motion after an event has ended. (Kenneth Lavrsen). http://www.lavrsen.dk/twiki/bin/view/Motion/BugReport2005x08x05x173526 * Option switch filter used print_int instead of print_bool when motion.conf was saved. * Removed all warnings originating from the motion sources when running ./configure --with-developer-flags. The modifications were done by the following people: Peter Holik, Bill Brack, Angel Carpintero and Kenneth Lavrsen. http://www.lavrsen.dk/twiki/bin/view/Motion/ReduceWarningsPatch * Implemented Threadnr in TLS (thread-local storage)patch. It puts the thread number into TLS and modifies motion_log() so that we do not have to drag the cnt struct around just to be able to print the thread number in the log and on the console. (Per Jönsson with additional removal of unused cnt by Kenneth Lavrsen). http://www.lavrsen.dk/twiki/bin/view/Motion/ThreadNrTlsPatch * Removed old unused code related to read mode (not mmap) from V4L devices. * Motion loop resets its frame timer when the image received is from a netcam. This lowers the actual framerate of Motion to the rate the netcam can actually keep up with. * Last --with-developer-flags warnings eliminated simply by swapping the order of the #include statements in the sources (Bill Brack and Kenneth Lavrsen). * Switchfilter feature repaired. It was called inside motion_detected() after overlays on cnt->img.out were added which meant that the feature also detected all the overlays, smartmasks, fixed mask and text. It is now moved to the motion_loop right after the lightswitch feature and before any overlays are added. * Fixed small bug where motion was detected when using a tracking camera and the camera moved to center position when gap period expires. The fix includes gathering the updating of reference frame in one place only in the motion_loop. * Implemented the new text option text_event and new conversion specifier %C. Option text_event defines the value %C which then can be used in filenames and text_right/text_left. The text_event/%C uses the time stamp for the first image detected in a new event. Default value is %Y%m%d%H%M%S. %C is an empty string when no event is in progress (gap period expired). Pre_captured and minimum_motion_frames images are time stamped before the event happens so %C in text_left/right does not have any effect on those images. http://www.lavrsen.dk/twiki/bin/view/Motion/EventConvertionSpecifierDiscussion * Renamed some variables related to time to be better descriptive of function and type. * Added new option 'sql_user_text'. This can be defined with the same conversion specifiers as text_xxx, on_xxxx and filenames. The SQL field text_left has been removed and replaced by a field user_text which is used for storing the interpreted value of sql_user_text. * Added new SQL field event_time_stamp of the type TIMESTAMP. * RPM specs file changed as suggested for use in the Livna repository. * The lightswitch and switchfilter features have been moved up before the despeckle features are run. This should ensure that both algorithms work on raw unfiltered motion pixels which they both were designed for. http://www.lavrsen.dk/twiki/bin/view/Motion/BugReport2005x10x05x212444 * Added help texts in conf.c and motion-dist.conf describing the %t specifier. Added a good example of use in motion-dist.conf. * Added two new conversion specifiers: %f which is filename (full path) and %n which is filetype (sqltype) valid in on_picture_save, on_movie_start, on_movie_end and sql_query. This also means that filename is no longer appended at the end of the 3 on_xxxx commands. * Removed the sql_user_text option that was added in snap 2 * Added new sql_query option. This in combination with convertion specifiers incl the two new %f and %n enables the user to use any database structure they please. Added fields is now a simple matter of modifying the sql query. The default is the same as the default in snap1. * Change the sequence of events connected with creating files. Data is now written to the databases (if used) before an external comments is on (on_xxxx options) allowing the external program to use the new data in the database * Added an infinite retry scheme for netcams that are not available when Motion is started. Instead of just dying, Motion now retries every 10 seconds until the netcam is available. Until the netcam is available Motion enters the normal flow with the same grey image with a text information being fed to webcam, timelapse, snapshots, vloopback etc. Motion uses the width and height from the config file for this. It is a good idea to setup width and height so it is the same as the netcam. If the dimensions are the same Motion will switch over to the netcam seemlessly. If the dimensions are different Motion will perform a quick restart so all the many internal buffers can be initialized properly. * Added a better error handling of a netcam that changes dimensions while Motion is running. Instead of just writing error messages Motion restarts quickly to recover from this change. Note the now more well defined error coding for vid_next for both netcams and V4L cams. * Fixed small bug where the displayed time in the grey error image shown during start with unavailable netcam could show a garbage value under rare circumstances. * Restored the function sigchild_handler so it contains the same code as before motion-3.2.1_snap9. They is done in an attempt to fix an old problem with zombie child processes that has shown up again. http://www.lavrsen.dk/twiki/bin/view/Motion/BugReport2005x11x13x115016 * Move the declaration of sig_handler_action and sigchild_action from the setup_signals function where they are local and will be destroyed and out in main just before setup_signals is called. Changed the function setup_signals so the two structs are passed as pointers. * Added new option track_auto which is a boolean option (on or off) with default value off. This enable people to start Motion with auto tracking enabled. Changing the config value for track_auto and enabling the auto tracking via the httpd track/auto has the exact same effect. * Added 3 new tracking options: track_step_angle_x, track_step_angle_y, and track_move_wait. The options track_step_angle control the movement during auto tracking and are currently only active for the pwc type tracking. The idea is that they can later also be used for the generic tracking as it evolves. The track_move_wait controls the number of frames after the camera has moved (auto or manual) during which motion detection is disabled. This option should be set so low that the motion detection is re-enabled the minute the camera is standing still again. Feature originally made by Moshe Van Der Sterre. Kenneth Lavrsen extended it to be more generic. http://www.lavrsen.dk/twiki/bin/view/Motion/PwcConfiguration * Implemented fix for missed snapshots with slow network cameras http://www.lavrsen.dk/twiki/bin/view/Motion/BugReport2006x02x07x162149 * Added some constants in video.c function v4l_picture_controls() which can help people hack an optimal set of values for controlling auto brightness for their particular camera. For now I am do not want to add all of these to the already too large number of motion config options. Maybe based on feedback we can permanently change the constants and add an additional auto brightness option. Or maybe a combined option that sets more constant based on an algorithm. http://www.lavrsen.dk/twiki/bin/view/Motion/BugReport2006x02x07x212816 * Fixed a syntax error in picture.c get_pgm() which caused the program to segfault when a mask file size did not match the picture size. Now the program correctly gives an error message and continues without the mask. http://www.lavrsen.dk/twiki/bin/view/Motion/BugReport2005x10x08x150720 * ffmpeg_filename has changed name to movie_filename to prepare for alternative movie encoding to the current ffmpeg based implementation and ffmpeg_filename will then be a bad name. * Fixed bug where variables time_last_frame and time_current_frame had been extended to also be used for snapshot feature but declaration was hidden between #ifdef HAVE_FFMPEG. http://www.lavrsen.dk/twiki/bin/view/Motion/BugReport2006x03x09x012244 * text_changes now shows a '-' when motion detection is paused instead of just showing 0 http://www.lavrsen.dk/twiki/bin/view/Motion/FeatureRequest2006x03x16x095713 * Improved reporting of thread numbers during startup in setup mode. (Peter Smith and Kenneth Lavrsen) http://www.lavrsen.dk/twiki/bin/view/Motion/SlightlyImprovedThreadCreationLogging * Implemented a fix for the rare problem where some experienced that the move file names would only consist of the extension .mpg or .avi with no name in front. The root cause was the use of sprintf for appending to strings. (Mike Kenney and Kenneth Lavrsen) http://www.lavrsen.dk/twiki/bin/view/Motion/SupportQuestion2005x09x05x133031 http://www.lavrsen.dk/twiki/bin/view/Motion/SupportQuestion2006x06x19x174238 * Altered the risky use of sprintf to snprintf in all places related to use with config strings that can become very long. * Removed the minimum_gap feature which was utterly useless * Added new feature: minimum_frame_time which enables capturing at a lower rate than 2 frames per second (Kenneth Lavrsen and Angel Carpintero) * Fixed the check for ffmpeg version. In rev 5503 of ffmpeg the FFMPEG_VERSION_INT was removed from libavcodec/avcodec.h. Instead we now use the equivalent LIBAVFORMAT_BUILD >= 4616 which is the 0.4.9pre1 version of ffmpeg. * Smartmask overlay feature did not set intensity correctly. * Fixed the thread number assignment which could goof up if netcams started very quickly before all thread were created at startup. * Fixed name space clash with libjpeg8 http://www.lavrsen.dk/foswiki/bin/view/Motion/BugReport2010x01x22x084753 Mike Lees * Added the onffmpegclose feature. * Fixed a serious stability issue related to syslog not being a fully re-entrant function. * Implemented the new brightness, contrast, hue, saturation features http://www.lavrsen.dk/twiki/bin/view/Motion/BrightnessContrastPatch Wim Lewis * Added EXIF feature for jpeg images , http://www.lavrsen.dk/foswiki/bin/view/Motion/ExifTaggingPatch Michal Licko * Track pan/tilt support for uvcvideo ( Michal Licko ,Dirk Wesenberg and Angel Carpintero ) http://www.lavrsen.dk/twiki/bin/view/Motion/LinuxUvcTrackingPatch Michael Luich * Added codec Ogg/Theora as new output format for regular movies. http://www.lavrsen.dk/foswiki/bin/view/Motion/OggTimelapse Bill Maidment * Fixed bug reporting errors when creating symlink to last snap. Philip Marien * Fixed a problem when compiling with --without-v4l configuration. Jeroen Massar * IPV6 for http-control and webcam stream not netcam yet http://www.lavrsen.dk/twiki/bin/view/Motion/IPv6 (Jeroen Massar & Angel Carpintero) Lionnel Maugis * ffmpeg code Andrew McCarthy * Added the netcam functionality to the original axis code. Ian McConnell * Fixed the problem with Netcams and mask files. * New despeckle feature. * Flexible on screen display feature based on strftime. * Flexible strftime based path names. * Fixed problem with snapshot names when name is lastsnap. * Fix for snapshots when using the "lastsnap" filename. * Provided "timelapse closes mpeg file when set to zero" feature. Randy McEoin * For adding the onmpeg command. Marcel J.E. Mol * new show.cgi and genhtml.sh, -a without alarm, both motion and normal images, various improvements and ideas Sean Murphy * Executing external commands nemosoft * For his differential view in the camstream program. It inspired me (Jeroen) to make this. And for a great program to test my video loopback support. (www.smcc.demon.nl/camstream/) nullset? * For the ir script to turn motion and lights on and of Onakra * Fix choose v4l2 palette , http://www.lavrsen.dk/twiki/bin/view/Motion/BugReport2008x01x21x043812 Mikko Paananen * Changed netcam open to use pipes and fixed authentication. Bill Payne, * External pipe to allow external video encoders http://www.lavrsen.dk/twiki/bin/view/Motion/DarkwindHackeronMotionPatching (Angel Carpintero, Bill Payne) Bowser Pete * Add swf codec to video creation. Asbjørn Pettersen * Netcam_ftp code fixes (Angel Carpintero and Asbjørn Pettersen) http://www.lavrsen.dk/twiki/bin/view/Motion/NetcamWithFtpEnhancements Pawel Pierscionek * Signal blocking during ioctls. * Greyscale blowup optimization Philippe Possemiers * For fixing the bug that prevented external commands, mail and sms from being called at the first event. * And for writing the send_jpg.py script. Alan Post * Pointed me to the exit(-1) instead of exit(1) calls. Christopher Price * Implemented Streaming Netcam Without Curl which enables connecting to network cameras both with single jpeg frame mode and streaming mjpeg mode. This enables much higher framerates with Netcams. (with Angel Carpintero). http://www.lavrsen.dk/twiki/bin/view/Motion/StreamingNetcamWithoutCurl * Netcam fixes and debug code by Christopher Price http://www.lavrsen.dk/twiki/bin/view/Motion/NetcamStabilityPatch * snap5_post1_video.c and snap5-post1 patches * Fixed netcam startup race condition. * Refactored image handling back to single unified function * Refactored reconnection algorithm * Jpeg only based connections should now use less cpu time * Temporarily removed support for devices that do not support content-length (in progress) * Synced syslog/printf style to new motion standard * Added developer debug trace defines/code * Defines now used for many constants * Netcam Stability Patch version snap6-post1 * Added support for netcams without content-length header (streaming only) * Remove memmem from netcam_wget.[c|h] (no longer used) * Several miscellaneous code cosmetic changes * Netcam Stability Patch version 3.2.1-snap7-post1 * Added support for non-streaming (image based) netcams without content-lengthheader. * Contributed code for new function in event.c close_anything_open() which is called from send_sms, send_mail and exec_command in order to prevent file descriptor and open sockets to be inherited by the shell causing freezing and instability. Code contributed by Christophe Grenier, Christopher Price and Kenneth Lavrsen. * More Netcam Stability Fixes (snap10-post1-6) http://www.lavrsen.dk/twiki/bin/view/Motion/NetcamStabilityPatch * Destroy mutexes in netcam_cleanup(). * Add reconnection for netcam_start() - this may block other cameras from starting up!. * Added additional defines for reconnect retries. * Change reconnection timeouts to 60 seconds. * Reworked close(sock) in netcam_connect, to insure future changes won't forget to close the socket. * Reworked reconnection for netcam_start() - disabled by default, see source for INIT_RECONNECT_RETRIES. * Break some long lines in code. * Replaced sleep with nanosleep per suggestion by Kenneth Lavrsen. * Added additional header validation check. * Changed a couple fd references to use RBUF_FD. * Added error message if jpeglib error occurs. * Removed additional header validation check. * Limited times headers will be checked. * Removed mutex lock around netcam_start() in video.c, hopefully race conditions are fixed. * Added additional headers in http request. * Added back header validation (should fix netcam_read_header lockups). * Detect when there is no data on socket in netcam_read_ functions (should fix netcam_read_image_contentlength() and * netcam_read_image_no_contentlength() lockups). * Rearranged timeout assignments for pthread_cond_timedwait() calls. * Adjusted TIMEOUT_COND_WHICH to 4 seconds. * More Netcam Stability Fixes (snap11-post1-4) (Christopher Price) http://www.lavrsen.dk/twiki/bin/view/Motion/NetcamStabilityPatch * Reworked thread signal/wait conditions, should fix some race conditions. * Use gettimeofday() to determine thread timeouts, results in better accuracy. * Adjusted condition timeouts to smaller values due to usage of gettimeofday() and rework of thread signal/wait conditions. * Adjusted reconnection retries to 60 (every minute for an hour). * Fix bug where motion will not quit if requested when reconnecting. * Cruft, feature creep and redundant code removed. * Consolidated reconnection capability to unified netcam_reconnect function. * Rework netcam_start logic, minimize startup variables. * Rework netcam_stream_read and netcam_single_read logic. * Minor changes to netcam_next logic. * Fix bug in streaming camera without content-length, recent mod broke. * Fix bug in startup of single image reads without content-length. * More Netcam Stability Fixes (snap12-post1) (Christopher Price) http://www.lavrsen.dk/twiki/bin/view/Motion/NetcamStabilityPatch * Newrote url parser, better syntax checking and error handling of urls. * Userpass now allowed in url (http://user:pass@example.com/). Netcam_userpass has precedence, it will override a userpass embedded in the url. Dietz Proepper * Always output diff count and output image type selection rasca * A lot of the code in motion.c comes from his vidcat program which is part of the w3cam package. (jpeg creation and parts of the image capture function) (www.hdk-berlin.de/~rasca/w3cam/) Michael Reuschling * Fixed bug which caused Motion 3.1.18 fail to save timelapse mpegs when setting ffmpeg_timelapse = 1 (fixed by Michael Reuschling) http://www.lavrsen.dk/twiki/bin/view/Motion/BugReport2005x01x31x211756 Petter Reinholdtsen * Adding the install option to the makefile. Isaac Richte * V4L2 fourcc GRBG not supported, updated default value for v4l2_palette 17. http://www.lavrsen.dk/foswiki/bin/view/Motion/BugReport2009x10x29x222753 Marius Rieder * Handle mjpeg decoding and fix colour issue adding mjpegtools dependency http://www.lavrsen.dk/twiki/bin/view/Motion/MjpegColorIssue http://www.lavrsen.dk/twiki/bin/view/Motion/MjpegToYUV420pPatch (Marius Rieder, Angel Carpintero). James A. Russo. * Implemented ffmpeg_timelapse_mode feature. * Implemented enhanced SQL features. This adds logging of mpeg and prediction events to the MySQL/PostgreSQL feature. * Replaced the mime file types by a more refined filetype scheme that allows more refined control for SQL and other future control. Jason Sharpee * Avoid random errors , initialising some structs for V4L1 http://www.lavrsen.dk/twiki/bin/view/Motion/BugReport2007x11x26x010755 (Jason Sharpee & Angel Carpintero) Pete Shipley * Fix the problem that happens in FreeBSD and Debian Sarge because version of ffmpeg is LIBAVFORMAT_BUILD < 4629. ( Angel Carpintero and Pete Shipley) http://www.lavrsen.dk/twiki/bin/view/Motion/BugReport2006x01x12x120335 Gunnar Skjold * Fixed http pause feature so that pausing thread 0 now pauses all threads. http://www.lavrsen.dk/twiki/bin/view/Motion/BugReport2006x07x10x111239 Peter Smith * Improved reporting of thread numbers during startup in setup mode. (Peter Smith and Kenneth Lavrsen) http://www.lavrsen.dk/twiki/bin/view/Motion/SlightlyImprovedThreadCreationLogging * Ffmpeg code mutex locking fix http://www.lavrsen.dk/twiki/bin/view/Motion/BugReport2006x04x07x164654 * Ffmpeg avicodec logging improved (Peter Smith and Kenneth Lavrsen) http://www.lavrsen.dk/twiki/bin/view/Motion/FfmpegAvicodecLogging * Improved upon a few ambiguous log messages which may be emitted by the Event handling code with regards to Ffmpeg (Peter Smith) http://www.lavrsen.dk/twiki/bin/view/Motion/LoggingEventFix Roberto Spadim * Fixed compatibility problem with Palantir. Fixed by making output more compatible with RFC (\r\n). Original fixes by Roberto Spadim and Angel Carpintero. However this fix made Firefox flicker even more than it normally does. Final fix which works in both Palantir client, Firefox and Cambozola was made by Kenneth Lavrsen. This closes the following bugs: http://www.lavrsen.dk/twiki/bin/view/Motion/BugReport2005x05x02x205307, http://www.lavrsen.dk/twiki/bin/view/Motion/BugReport2005x05x07x042849 Daniel Sterling * Studies of the performance of Motion. * Night compensation fix. * Changed the webcam_port value to 0 in motion-dist.conf to avoid that people get segmentation faults when having 2 or more cameras and webcam_port not set in the thread config files. * Implemented improved handling of config strings. This plugs the memory leak when changing string type options via XML-RPC. It also makes the memory handling more elegant/optimal and finally it now allows strings to be as long as allowed by the environment variable PATH_MAX. * Kenneth and Daniel added more comments to motion.c and conf.c. * Made the XMLRPC able to handle errors without crashing. * Daniel Sterling and Kenneth Lavrsen added a feature that checks for two threads having the same webcam_port. If this is the case the last thread gets its webcam disabled and a warning message is written to console and syslog. * Fixed a calculation error in alg_diff_fast(). Tommy Svensson * Wrote the original patch for supporting pan/tilt with Logitech Quickcam Sphere/Orbit Timo Taskinen * Added Flash video format (FLV) to ffmpeg. http://www.lavrsen.dk/twiki/bin/view/Motion/FeatureRequest2007x07x19x131921 technolust.cx * For hosting motion.technolust.cx Mark Thomas * Created the original thread patch for motion enabling motion to watch multiple cameras. Dirk Traenapp * Added the mpeg creation on exit and SIGUSR1, also made the start for max_mpeg_time. * Found the 'strtok' call that caused motion to crash under RH7.0 Jukka Ukkonen * On FreeBSD configure defines a redundant freebsd for motion. Fixed by replacing -D__freebsd_ by BSD macro included in sys/param.h for BSD platforms. (JukkaUkkonen and Angel Carpintero) http://www.lavrsen.dk/twiki/bin/view/Motion/BugReport2006x07x08x070417 Moshe Van Der Sterre * Added 3 new tracking options: track_step_angle_x, track_step_angle_y, and track_move_wait.

Kenneth Lavrsen extended it to be more generic. http://www.lavrsen.dk/twiki/bin/view/Motion/PwcConfiguration Folkert Van Heusden * Maintained the code from version 3.1.9 till 3.1.12-rc1 Including features like.. * Error reporting to syslog. * Better memory allocation. low_cpu feature extension to configurable frame rate. * First work on Logitech Sphere/Orbit tracking. * Implemented original pre-record feature. Misc code optimisations * Closed 2 memory-leaks (two 'FILE *' were not closed) in the webcam-interface. James Van Vleet * CPU VIA Ezra C3 autodetection support added. http://www.lavrsen.dk/twiki/bin/view/Motion/VIAEzraC3Patch Simon Walls * Netcam Keepalive and HTTP/1.1 http://www.lavrsen.dk/twiki/bin/view/Motion/FeatureRequest2007x01x22x231542 * Better debug in netcam for "Error reading image header" http://www.lavrsen.dk/twiki/bin/view/Motion/BugReport2008x02x27x092849 (Simon Walls) Sean Watkins * Created a centralized logging function that became event() Joerg Weber * Added the new labeling motion detection feature. * Added the new Smartmask feature. * Implemented new preview patch (Joerg Weber) http://www.lavrsen.dk/twiki/bin/view/Motion/PreviewShotsPatch * Implemented an improvement of Smartmask so that the mask is cleared when the smart_mask_speed is set from a non-zero to zero * Implemented an improvement of noise_tune with smart mask (and probably also in general) * Added Best Preview Patch http://www.lavrsen.dk/twiki/bin/view/Motion/BestPreviewShot * Added the new feature Setup Mode (Joerg Weber). This also enables much more error messages given to the console when in non-daemon mode while still preserving the messages in syslog which are important for daemon mode debugging. http://www.lavrsen.dk/twiki/bin/view/Motion/SetupModePatch * Fixed a bug in noise tune which was most visible at very low light. * Improved console output in setup mode. Now also outputs threshold. * Improvement in the noise-tune algorithm. * Implemented new Generic onxxxx features. Function --- Old Option --- New Option Start of event (first motion) --- execute --- on_event_start End of event (no motion for gap seconds) --- New! --- on_event_end Picture saved (jpg or ppm) --- onsave --- on_picture_save Movie starts (mpeg file opened) --- onmpeg --- on_movie_start Movie ends (mpeg file closed) --- onffmpegclose --- on_movie_end Motion detected --- New! --- on_motion_detected http://www.lavrsen.dk/twiki/bin/view/Motion/OnXxxCommandsPatch and http://www.lavrsen.dk/twiki/bin/view/Motion/OnXxxxFeatureDiscussion * Fixed small bug when pre_capture buffer is resized during operation. * Changed the order of drawing the red mask in setup mode so that the smartmask is drawn after the fixed mask. * Improved the display of fixed mask. It is now shown as grey instead of red. This makes it easier to see the smart mask working when you also have a fixed mask. * Improved the labelling algorithm so that locate feature and tracking features includes all labelled areas above threshold. http://www.lavrsen.dk/twiki/bin/view/Motion/ImprovedLabellingPatch * Make the creation of reference frame and the decay mechanism depending on how much motion was detected relative to threshold setting. http://www.lavrsen.dk/twiki/bin/view/Motion/ReferenceFramePatch * Removed low_cpu feature. * Removed night_compensate feature * Implemented a new reference frame algorithm to improve object recognition and location. * Improved smartmask feature: real moving objects don't trigger the mask anymore. * Added area_detect feature. * Add draw a RED box around the movement as default. * Split locate_motion into separate 'mode' and 'style' option to allow all possible combinations. * Gapless_event mode. * Limit detection rate to 3fps at framerates above 5fps, to reduce CPU load. * Fixed mask overlay in setup mode is now green instead of white. Dirk Wesenberg * Track pan/tilt support for uvcvideo ( Michal Licko ,Dirk Wesenberg and Angel Carpintero ) http://www.lavrsen.dk/twiki/bin/view/Motion/LinuxUvcTrackingPatch Tristan Willy * Wrote Axis 2100 support and added the check for ~/.motion/motion.conf Robert Eugene Wood * Inverse pixels for locate box. Andreas Wrede * Allow compile with NetBSD and make LP64 compliant video_freebsd.c Damian Wrobel * Fix a segfault adding correct size to be used for bayer2rgb24(). http://www.lavrsen.dk/twiki/bin/view/Motion/BugReport2007x03x30x175913 Yieldtech * These guys are making a complete linux based security system with motion as one of its components. * They did the mysql support, new fileformat and the symbolic link to the snapshots. You can find them at yieldtech.cz Christian W. Zuckschwerdt * Modified the Makefile and configure files to be more flexible.

A: Appearantly the behaviour of strtok in glibc has changed somewhat. This problem should be fixed as of 2.3 Q: Were does motion look for the config file? A: First it will look for 'motion.conf' in the current directory, next it will try to find '.motion/motion.conf' in your home directory (pointed to by the HOME environment variable). If these don't exist it will try to open '/usr/local/etc/motion.conf' if you specified /usr/local as the prefix to configure (this is the default). Q: What codingstyle is used for motion? A: Motion follows the same style as the linux kernel. Read Documentation/Codingstyle in the kernel tree for some good reasons. Also be aware that motion is multithreaded and as such all functions should be reentrant, using static variables is usually a bad idea. motion-28b7cb2a4297c78b9c08c9ce29a648aeb22120d0/INSTALL000066400000000000000000000001571230376121600210530ustar00rootroot00000000000000Very simple: type: ./configure followed by: make And make install Next read the README motion-28b7cb2a4297c78b9c08c9ce29a648aeb22120d0/Makefile.in000066400000000000000000000315341230376121600220720ustar00rootroot00000000000000################################################################################ # Makefile for Motion # ################################################################################ # Copyright 2000 by Jeroen Vreeken # # # # This program is published under the GNU public license version 2.0 or later. # # Please read the file COPYING for more info. # ################################################################################ # Please visit the Motion home page: # # http://www.lavrsen.dk/twiki/bin/view/Motion # ################################################################################ CC = @CC@ INSTALL = install ################################################################################ # Install locations, controlled by setting configure flags. # ################################################################################ prefix = @prefix@ exec_prefix = @exec_prefix@ bindir = @bindir@ mandir = @mandir@ sysconfdir = @sysconfdir@ datadir = @datadir@ datarootdir = @datarootdir@ docdir = $(datadir)/doc/@PACKAGE_NAME@-@PACKAGE_VERSION@ examplesdir = $(datadir)/@PACKAGE_NAME@-@PACKAGE_VERSION@/examples ################################################################################ # These variables contain compiler flags, object files to build and files to # # install. # ################################################################################ CFLAGS = @CFLAGS@ -Wall -DVERSION=\"@PACKAGE_VERSION@\" -Dsysconfdir=\"$(sysconfdir)\" LDFLAGS = @LDFLAGS@ LIBS = @LIBS@ VIDEO_OBJ = @VIDEO@ OBJ = motion.o logger.o conf.o draw.o jpegutils.o vloopback_motion.o $(VIDEO_OBJ) \ netcam.o netcam_ftp.o netcam_jpeg.o netcam_wget.o track.o \ alg.o event.o picture.o rotate.o webhttpd.o \ stream.o md5.o @FFMPEG_OBJ@ @SDL_OBJ@ @RTPS_OBJ@ SRC = $(OBJ:.o=.c) DOC = CHANGELOG COPYING CREDITS INSTALL README motion_guide.html EXAMPLES = *.conf motion.init-Debian motion.init-Fedora motion.init-FreeBSD.sh PROGS = motion DEPEND_FILE = .depend ################################################################################ # ALL and PROGS build Motion and, possibly, Motion-control. # ################################################################################ all: progs ifneq (,$(findstring freebsd,$(VIDEO_OBJ))) @echo "Build complete, run \"gmake install\" to install Motion!" else @echo "Build complete, run \"make install\" to install Motion!" endif @echo progs: pre-build-info $(PROGS) ################################################################################ # PRE-BUILD-INFO outputs some general info before the build process starts. # ################################################################################ pre-build-info: @echo "Welcome to the setup procedure for Motion, the motion detection daemon!

This version has been tested with TV Card ( Miro PCTV pro ), but should work by any framegrabber supported by bktr driver. * How configure your capture card * 1-. Load the bktr modules type as root : kldload bktr_mem.ko kldload bktr.ko You can setup this in your /boot/loader.conf adding : bktr_mem_load="YES" bktr_load="YES" 2-. Configure your card settings ( tuner type , format and card ). Type as root : sysctl hw.bt848.card=1 ( Miro pctv ) sysctl hw.bt848.tuner=10 ( PHILIPS_FR1216_PAL ) sysctl hw.bt848.format=0 ( PAL ) or add to /etc/sysctl.conf adding : hw.bt848.card=1 hw.bt848.tuner=10 hw.bt848.format=0 * To compile motion in FreeBSD ( should work in OpenBSD and NetBSD ) : autoconf ./configure of CC=gcc34 ./configure ( to override the default gcc version) gmake gmake install ( ./configure --without-bktr , to work only with network cameras ). Tested in FreeBSD 4.9/4.1x/5.x/6.x . Packages needed (dependencies for 6.x): - autoconf-2.59_2 - gcc-3.4.6_20051206 - m4-1.4.4 - linuxthreads-2.2.3_19 only if you don't want native freebsd pthread - jpeg-6b_4 or above - gmake-3.80_2 ( GNU Make ) - ffmpeg-0.4.9.p1_6 ( mpeg1/4 video encoders ). - mysql-server , mysql-client ( database backend support ). - postgresql-devel , postgresql ( database backend support ). - kernel with bktr support ( GENERIC kernel has by default support ). * webcams pwc based - pwcbsd-1.4.1_1 ( with mmap support ) - v4l_compat-1.0.20060801 run : ./configure --with-pwcbsd ; gmake ; gmake install * TODO * -------- - Improve the capture method ( double buffer , async capture ). - Detect pixelformat , palettes format , etc ... - Implement tuner capture ( now only video / svideo capture implemented ). - Code clean up. - And many others ...

Makes Motion so it only supports network cameras. --without-sdl Compile without sdl support to get stream in SDL window. --with-jpeg-turbo=DIR Specify the prefix for the install path for jpeg-turbo for optimized jpeg handling (optional). --with-jpeg-mmx=DIR Specify the prefix for the install path for jpeg-mmx for optimized jpeg handling (optional). If this is not specified motion will try to find the library /usr/lib/libjpeg-mmx.a /usr/local/lib/libjpeg-mmx.a. --with-ffmpeg=DIR Specify the prefix for the install path for libavcodec/libavformat (part of ffmpeg) be able to encode mpeg movies realtime. If this is not specified motion will try to find the libraries in /usr and /usr/local. --with-ffmpeg-headers=DIR Specify the prefix for ffmpeg headers. --without-sqlite3 Disable sqlite3 support in motion. --without-mysql Disable mysql support in motion. --with-mysql-lib=DIR Normally, configure will scan all possible default installation paths for mysql libs. When it fails, use this command to tell configure where mysql libs installation root directory is. --with-mysql-include=DIR Normally, configure will scan all possible default installation paths for mysql include. When it fails, use this command to tell configure where mysql include installation root directory is. --without-pgsql Disable PostgreSQL support in motion. --with-pgsql-lib=DIR Normally, configure will scan all possible default installation paths for pgsql libs. When it fails, use this command to tell configure where pgsql libs installation root directory is. --with-pgsql-include=DIR Normally, configure will scan all possible default installation paths for pgsql include. When it fails, use this command to tell configure where pgsql include installation root directory is. --without-optimizecpu Exclude autodetecting platform and cpu type. This will disable the compilation of gcc optimizing code by platform and cpu. --with-developer-flags Causes practically all of the possible gcc warning flags to be set. This may produce a large amount of warnings. Some influential environment variables: CC C compiler command CFLAGS C compiler flags LDFLAGS linker flags, e.g. -L if you have libraries in a nonstandard directory LIBS libraries to pass to the linker, e.g. -l CPPFLAGS (Objective) C/C++ preprocessor flags, e.g. -I if you have headers in a nonstandard directory CPP C preprocessor Use these variables to override the choices made by `configure' or to help it to find libraries and programs with nonstandard names/locations.

These pictures are not very useful for normal presentation to the public but they are quite useful for testing and tuning and making mask files as you can see exactly where motion sees something moving. Motion is shown in greytones. If labelling is enabled the largest area is marked as blue. Smart mask is shown in read. .TP .B Normal image A "normal" image is the real image taken by the camera with text overlayed. .TP .B Threads and config files If Motion was invoked with command line option -c pathname Motion will expect the config file to be as specified. When you specify the config file on the command line with -c you can call it anything. .br If you do not specify -c or the filename you give Motion does not exist, Motion will search for the configuration file called 'motion.conf' in the following order: .br 1. Current directory from where motion was invoked .br 2. Then in a directory called '.motion' in the current users home directory (shell environment variable $HOME). E.g. /home/goofy/.motion/motion.conf .br 3. The directory defined by the --sysconfdir=DIR when running .configure during installation of Motion (If this option was not defined the default is /usr/local/etc/) .br If you have write access to /usr/local/etc then the editor recommends having only one motion.conf file in the default /usr/local/etc/ directory. .br Motion has a configuration file in the distribution package called motion-dist.conf. When you run 'make install' this files gets copied to the /usr/local/etc directory. .br The configuration file needs to be renamed from motion-dist.conf to motion.conf. The original file is called motion-dist.conf so that your perfectly working motion.conf file does not accidentally get overwritten when you re-install or upgrade to a newer version of Motion. .br If you have more than one camera you should not try and invoke Motion more times. Motion is made to work with more than one camera in a very elegant way and the way to do it is to create a number of thread config files. Motion will then create an extra tread of itself for each camera. If you only have one camera you only need the motion.conf file. The minute you have two or more cameras you must have one thread config file per camera besides the motion.conf file. .br So if you have for example two cameras you need motion.conf and two thread config files. Total of 3 config files. .br An option that is common to all cameras can be placed in motion.conf. (You can also put all parameters in the thread files but that makes a lot of editing when you change a common thing). .br An option that is unique to a camera must be defined in each thread file. .br The first camera is defined in the first thread file called from motion.conf. The 2nd camera is defined in the 2nd thread file called from motion.conf etc. .br Any option defined in motion.conf will be used for all cameras except for the cameras in which the same option is defined in a thread config file. .br Motion reads its configuration parameters in the following sequence. If the same parameter exists more than one place the last one read wins. .br 1. Motion reads the configuration file motion.conf from the beginning of the file going down line by line. .br 2. If the option "thread" is defined in motion.conf, the thread configuration file(s) is/(are) read. .br 3. Motion continues reading the rest of the motion.conf file. Any options from here will overrule the same option previously defines in a thread config file. .br 4. Motion reads the command line option again overruling any previously defined options. .br So always call the thread config files in the end of the motion.conf file. If you define options in motion.conf AFTER the thread file calls, the same options in the thread files will never be used. So always put the thread file call at the end of motion.conf. .br If motion is built without specific features such as ffmpeg, mysql etc it will ignore the options that belongs to these features. You do not have to remove them or comment them out. .br If you run the webcontrol command http://host:port/0/config/writeyes, motion will overwrite motion.conf and all the thread.conf files by autogenerated config files neatly formatted and only with the features included that Motion was built with. If you later re-build Motion with more features or upgrade to a new version, you can use your old config files, run the motion.conf.write command, and you will have new config files with the new options included all set to their default values. This makes upgrading very easy to do. .TP .B Conversion Specifiers for Advanced Filename and Text Features The table below shows all the supported Conversion Specifiers you can use in the options text_left, text_right, snapshot_filename, picture_filename, movie_filename, timelapse_filename, on_area_detected, on_camera_lost, on_event_start, on_event_end, on_picture_save, on_movie_start, on_movie_end, and on_motion_detected. .br In text_left and text_right you can additionally use '\n' for new line. .TP .B %a The abbreviated weekday name according to the current locale. .TP .B %A The full weekday name according to the current locale. .TP .B %b The abbreviated month name according to the current locale. .TP .B %B The full month name according to the current locale. .TP .B %c The preferred date and time representation for the current locale. .TP .B %C Text defined by the text_event feature .TP .B %d The day of the month as a decimal number (range 01 to 31). .TP .B %D Number of pixels detected as Motion.

Motion Overview

What is Motion?

Motion is a program that monitors the video signal from one or more cameras and is able to detect if a significant part of the picture has changed. Or in other words, it can detect motion.

The program is written in C and is made for the Linux operating system.

Motion is a command line based tool. It has absolutely no graphical user interface. Everything is setup either via the command line or via a set of configuration files (simple ASCII files that can be edited by any ASCII editor).

The output from motion can be:

  • jpg files
  • ppm format files
  • mpeg video sequences

How do I get Motion and what does it cost?

Motion is an open source type of project. It does not cost anything. Motion is published under the GNU GENERAL PUBLIC LICENSE (GPL) version 2 or later. It may be a bit difficult to understand all the details of the license text (especially if your first language is not English). It means that you can get the program, install it and use it freely. You do not have to pay anything and you do not have to register anywhere or ask the author or publisher for permission. The GPL gives you both rights and some very reasonable duties when it comes to copying, distribution and modification of the program. So in very general terms you do not have to worry about licensing as a normal hobby user. If you want to use Motion in a commercial product, if you want to distribute either modified or original versions of Motion - for free or for a fee, you should read the license carefully. For more information about free software and the GPL, I encourage you to study the very interesting documents about the subject available the of the Free Software Foundation pages about the Philosophy of the GNU Project.

Maintenance and Support

Both Motion and the Motion Guide are written by people that do all this as a hobby and without asking for any payments or donations. We have a life other than developing Motion and its documentation. This means that bugfixes and updates to this guide are done as our time and families allow it. You are however encouraged to participate and contribute in a very active mailing list. It is a list with a very "positive attitude" and with many contributors that propose features, post patches, discuss problems and patiently answer newbie questions with a very positive spirit. Expect 1-10 emails per day.

To get motion direct your browser to the Motion Homepage.

On the Download Files page you will find a links to the latest stable version both as sources and binaries for some of the most popular Linux distributions. You will also find links to development versions. Snapshot releases are special test releases that are normally very stable. Every day a Motion Daily Source Snap is created from the Motion Subversion

Motion was originally written by Jeroen Vreeken who still actively participates in the development of Motion and later Folkert van Heusden continued as a lead programmer with Kenneth Lavrsen responsible for Motion Guide, website and releases on Sourceforge.

From version 3.1.12 Motion is now project managed entirely by Kenneth Lavrsen, and the project now shift towards being developed by many contributers.

For support we encourage you to join the mailing list instead of writing to Jeroen, Folkert or Kenneth directly. We are all very active on the mailing list and by using the mailing list much more users will have benefit of the answers. Newbies and stupid questions are welcome on the list. Contributions in the form of patches are also very welcome on the mailing list.

Which version to download and use?

Versions 3.2.X are the current version. There is at the moment no development branch. The versions 3.1.X ended at 3.1.20 and there will be no more 3.1.X releases. If you use use a version older than 3.2.X you are encouraged to update.

Since 3.1.13 quite many options have been renamed to make setting up Motion easier. From 3.1.17-18 some unfinished features have been removed. The Berkeley mpeg feature is now removed because the ffmpeg feature is now mature and much better working. At version 3.1.18 a new network camera feature was introduced replacing the old cURL based netcam code and introducing support of mjpeg streaming cameras. However this new code was quite difficult to get stable. During the development of 3.2.2 the network camera code was totally rewritten again learning from our experience and now finally it seems to be stable.

Since 3.2.3 Debian users can find binary packages on the Motion Sourceforge file download page. You can find Debian versions of Motion in different Debian repositories but they are all out of date and hardly ever get updated.

You can find more information and links at the Motion Homepage.

FreeBSD

Motion is originally developed for Linux and it is still mainly developed and supported for this platform. From version 3.1.15 an experimental port has been made by Angel Carpintero. Not all features of Motion are supported at this time and it still needs a lot of test time on different hardware. Angel is very interested in feedback. Join the Motion Mailing List and give your feedback there. Patches for bugfixes and for enabling the missing features are very welcome. The rest of this guide is still mainly targeted for Linux users. Follow this topic to Install FreeBSD.

MacOSX

From Motion version 3.2.4 it is now also possible to build and install Motion under MacOSX. Feature set it the same as for FreeBSD. See the MacOSX topic for specific help how to install Motion and its dependencies on MacOSX. Again this port has been contributed by Angel Carpintero.

Documentation

You have the following sources of information:

Supported Hardware

Input devices: Here we are thinking about the cameras.

Motion supports video input from two kinds of sources.

Standard video4linux devices (e.g. /dev/video0). Motion has no drivers for cameras. Installing the camera itself is outside the scope of this document. But here are some nice links.

Network cameras (which are actually cameras with a built in web server that can be connected directory to your network).

Known Problems

See also the Frequently Asked Questions and Bug Reports for known open bugs.

Kernel 2.6 and pwc. Note that for kernel 2.6 there is a new release of the Philips WebCam (pwc) drivers 10.0.X. It is recommended to install this. At the time of this being written the 2.6.12+ kernels have a version of pwc built-in but it is a cripled version which can only support very small picture size. You can however download the latest source code of the pwc driver (at this time 10.0.11) and build it without having to rebuild your kernel. But you will need to have either the kernel sources or a special kernel-header package installed to compile it. See Installation of PWC page which is also hosted in this wiki.

If you use use a Logitech Quickcam Orbit or Sphere using the driver pwc/pwcx and kernel 2.6.X you should replace the file in the Motion sources called pwc-ioctl.h with the one that comes with the your pwc version. Motion is shipped with 3 versions of pwc-ioctl.h-VERSION. Rename the one that fits your major pwc version number best to pwc-ioctl.h (after renaming the current to something else). There has been some small adjustments in the API that requires that you have the right header file.

Camera picture dimensions must be multiple of 16 Dimentions of camera image must have both height and width that are a multiple of 16. Thís is normally not a problem. All standard sizes like 640, 480, 352, 320, 288, 240, ...etc are multiples of 16. But if you intend to monitor a network camera which is saving jpeg images you may have to pay attention to the dimensions of the picture.

ffmpeg_filename has changed name to movie_filename The 3.2.5 release contains a motion_guide and man page in which it was forgotten to change ffmpeg_filename to movie_filename. Please note that the option that defines the filenames for mpeg movies is now called movie_filename. This change is made because we may soon implement alternatives to ffmpeg and then ffmpeg_filename will be a bad name. This is fixed in release 3.2.5.1.

error: `time_current_frame' undeclared (first use in this function) A bug in 3.2.5 and 3.2.5.1 where a bugfix related to snapshot feature has created a new bug when you compile Motion without ffmpeg libs installed. This is fixed in 3.2.6.

How do I install Motion?

Motion is mainly distributed as source files that you must compile yourself. There is also an RPM made on Fedora Core 3. And Debian packages are available for selected versions.

The short overview of the steps to install Motion from sources.

  • Preparation: Motion uses a number of shared libraries that must be installed on your computer before you can build Motion. The needed shared libraries depends on the features you wish to use. Features network camera, ffmpeg, MySQL and PostgreSQL needs specific shared libraries installed. See preparation section for more information.

  • Download the motion source files (distributed as tar'ed and compressed files). Place the file in a place of your own choice.

  • Untar and uncompress the file to the place you want the program installed. Editor recommends placing the motion source file directory in /usr/local. If you do not have write access to the /usr/local directory (you are under the mercy of an ignorant system administrator with a severe case of paranoia) - you can install the program in a directory in your home directory. You will then need to read the next section about how to configure before you compile the program. Below is shown the exact commands using version 3.2.X installed in /usr/local as an example (replace /path/to with the actual placement of the tar.gz file). 
    cd /usr/local
tar -xvzf /path/to/motion-3.2.X.tar.gz
  • You will now have created a directory called motion-3.2.X. You can rename it to motion (mv motion-3.1.X motion). I recommend creating a symbolic link to the current version. This way you can more easily experiment with different version simply by changing the link. 
    ln -s motion-3.2.X motion
  • Now change to the new directory 
    cd motion
  • Run configure. You can start with the defaults. If you need to modify the installation parameters you can read the next section. 
    ./configure
  • Build the code 
    make
  • Install the code, manual page, etc 
    make install
  • In /etc/motion/etc you will find a file called motion-dist.conf. If it is the first time you install Motion - rename this file to motion.conf and edit as a minimum the settings: videodevice, input, norm, frequency, width, height and target_dir. That should get you going.

  • Run the program. To enable more features you must modify the config file. 
    motion

Preparation For Install

Note: If you're using SuSE 9.2, you might want to ADDITIONALLY have a look at Compiling on SuSE 9.2. As mentioned on that page as well, you will still need to read the instructions here as well.

Before you start you may need to install a number of shared libraries that Motion uses. If they are missing the feature will simply normally not be included. Most of these libraries can be found on the CDs of your distribution. A few will have to be downloaded from the Internet. Note that when you install software using pre-compiled binaries (Redhat type RPMs, Debian debs etc) you normally only get what is needed to run the programs themselves. In order to compile other programs from source that uses these pre-compiled libraries you also need to installed the development packages. These are normally called the same name as the package suffixed by -devel or -dev. These development packages contains the header files (xxx.h) that Motion needs to build with the shared libraries. If you build a library from sources you already have these header files. It is recommended to simply install the pre-compiled binary packages and their development brothers.

This is a list of shared libraries used by Motion and the RPM packages that provides them.

Motion will always need these libraries to be built and work
Library RPM Packages Debian Packages
libm, libresolv, libdl, libpthread, libc, ld-linux, libcrypt, and libnsl glibc and glibc-devel libc6 , libc6-dev ,libglib1.2
libjpeg libjpeg and libjpeg-devel libjpeg62 and libjpeg62-dev ( optional libjpeg-mmx-dev )
libz zlib and zlib-devel zlib1g and zlib1g-dev

For generating mpeg films with ffmpeg you need this library:
(See also the section Generating MPEG films with ffmpeg for how to install ffmpeg and libavformat/libavcodec)
Motion must be installed with revision 0.4.8 or 0.4.9pre1 of ffmpeg. Motion will also work with later CVS snapshots of ffmpeg but the API of the ffmpeg libraries changes all the time and without warning. If you have problems compiling Motion or with running an RPM of Motion you may try with an older CVS snapshot of ffmpeg. The Motion developers will like to know when ffmpeg changes and breaks Motion so we can fix it. Please file a bug report then with the exact date of the ffmpeg CVS version you have trouble with.

Configure Script

Configure is script that you run to setup the build environment for the C-compiler. It generates the "Makefile" which the program "make" uses to compile and install the software.

To run configure your current directory must be the motion directory. You type

./configure

You can add the parameter ./configure --help to get help on the different switches.

This is walk through of the options.

Option Description
Defaults for the options
are specified in brackets [ ] 		Editors comment
-h, --help display this help and exit  
--help=short display options specific to this package This command shows the options special to motion. Recommended
--help=recursive display the short help of all the included packages  
-V, --version display version information and exit Gives no useful information
-q, --quiet, --silent do not print `checking...' messages Not very useful. Output to screen is only a few lines anyway.
--cache-file=FILE cache test results in FILE. [disabled] No function
-C, --config-cach alias for `--cache-file=config.cache' No function
-n, --no-create do not create output files Used for testing if other switches produce error - without writing anything to the disk
--srcdir=DIR find the sources in DIR. [configure dir or `..'] DIR is a directory path. Editor recommends having the current directory being the motion installation directory and not using this switch. Then it defaults to the same directory as where the configure script is which is the current directory.
Installation directories:    
--prefix=PREFIX install architecture-independent files in PREFIX
[/usr/local] 		The default /usr/local means that the executable binary "motion" is installed in /usr/local/bin, the manual page in /usr/local/man/man1, the document files in /usr/local/docs/motion-version, configuration file in /usr/local/etc, and some examples config files in /usr/local/examples/motion-versionEditor recommends keeping this default setting.
If you are experimenting with many parallel versions it may be interesting to set the PREFIX to e.g. /usr/local/motion and then add /usr/local/motion/bin to your search path (or simply cd /usr/local/motion/bin before execution).
This way you can change version just by changing the symbolic link in /usr/local/motion as suggested earlier in this guide.
If you are installing the software on a machine where you have no access to the /usr/local but have write access to a home directory, then you should change this to point to a directory within your home tree.
Example: --prefix=$HOME
--exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
[PREFIX] 		If you set this it only defines an alternative installation directory for the executable binary.
Note: The executable binary will be placed in a directory "bin" below the directory specified by this option
Editor recommends leaving this as default (i.e. not setting it).
--bindir=DIR user executables [EPREFIX/bin] With this option you can control exactly in which directory the executable binary is installed. The previous option automatically adds the bin directory. Here you are in fill control.
--sbindir=DIR System admin executables [EPREFIX/sbin] Not used by motion. Ignore it.
--libexecdir=DIR program executables [EPREFIX/libexec] Not used by motion. Ignore it.
--datadir=DIR read-only architecture-independent data [PREFIX/share] Not used by motion. Ignore it.
--sysconfdir=DIR read-only single-machine data [PREFIX/etc] This is where motion both installs the default configuration file and also where it later searches for it.
Motion searches for the configuration file "motion.conf" in the following order:

    1. Current directory from where motion was invoked
    2. $HOME/.motion
    3. The sysconfig directory set by this switch. If not defined the default is /usr/local/etc/

Editor recommends leaving this at default. Be careful if you run "make install" again. This will overwrite the motion.conf file that you have edited and experimented with for hours. Make sure to keep a copy in a safe place. Alternatively, copy the working file to the motion base install directory. Then make install will simply copy the same file back again.
--sharedstatedir=DIR modifiable architecture-independent data [PREFIX/com] Not used by motion. Ignore it.
--localstatedir=DIR modifiable single-machine data [PREFIX/var] Not used by motion. Ignore it.
--libdir=DIR object code libraries [EPREFIX/lib] Not used by motion. Ignore it.
--includedir=DIR C header files [PREFIX/include] Not used by motion. Ignore it.
--oldincludedir=DIR C header files for non-gcc [/usr/include] Not used by motion. Ignore it.
--infodir=DIR info documentation [PREFIX/info] Not used by motion. Ignore it.
--mandir=DIR man documentation [PREFIX/man] Editor recommends the default.
Optional Packages:    
--with-ffmpeg=DIR Specify the path for the directory prefix in which the library and headers are installed.
If not specified configure will search in /usr/ and /usr/local/ 		DIR is the directory PREFIX in which the ffmpeg shared libraries and their headers are installed.
If you install ffmpeg from sources and use the default directories or if ffmpeg is installed as a binary package (RPM or deb) you do not need to specify the directory prefix. Configure will find the libraries automatically. If you installed ffmpeg from sources and specified a different --prefix when building ffmpeg you must use the same value for the DIR ( --with-ffmpeg=DIR).
For more information on FFmpeg see the FFmpeg project home page.
FFmpeg is a package that enables streamed video mpeg signal from your web camera to a browser.
Editor recommends installing ffmpeg from source and in the directory /usr/local/ffmpeg and build ffmpeg with ./configure --enable-shared.
This places libraries in /usr/local/lib and headers in /usr/local/include.
--without-ffmpeg Do not compile with ffmpeg Use this if you do not want to compile with ffmpeg. If ffmpeg is not installed you do not need to specify that Motion must build without ffmpeg.
--with-mysql-lib=DIR Lib directory of MySQL Normally, configure will scan all possible default installation paths for MySQL libs. When its fail, use this command to tell configure where MySQL libs installation root directory is.
--with-mysql-include=DIR Include directory with headers for MySQL Normally, configure will scan all possible default installation paths for MySQL include. When its fail, use this command to tell configure where MySQL include installation directory is. This is the directory with the MySQL header files.
--without-mysql Do not compile with MySQL support Use this if you do not want to include MySQL support in the package.
This can also be useful if you get compilation errors related to MySQL and you actually do not need the feature anyway.
--with-pgsql=DIR Include PostgreSQL support. DIR is the PostgreSQL base install directory, defaults to /usr/local/pgsql.
Set DIR to "shared" to build as a dynamic library, or "shared,DIR" to build as a dynamic library and still specify DIR. 		Default is that make searches in the normal installation directories of most distributions.
See section later about PostgreSQL about potential problem during compilation. There is an easy workaround for it.
--without-pgsql Do not compile with PostgreSQL support Use this if you do not want to include PostgreSQL support in the package.
This can also be useful if you get compilation errors related to PostgreSQL and you actually do not need the feature anyway.
--without-v4l Exclude using v4l (video4linux) subsystem. Makes Motion so it only supports network cameras. Can be used if you do not need V4L support and maybe lack some of the libraries for it.
--with-linuxthreads Use linuxthreads in BSD instead of native phtreads Only relevant for BSD. In Linux we always use this per default.
--without-bktr Exclude to use bktr subsystem , that usually useful for devices as network cameras ONLY used in *BSD
--with-jpeg-mmx=DIR Specify the prefix for the install path for jpeg-mmx for optimized jpeg handling (optional). If this is not specified motion will try to find the library /usr/lib/libjpeg-mmx.a /usr/local/lib/libjpeg-mmx.a. Considered experimental
--without-optimizecpu Exclude autodetecting platform and cpu type. This will disable the compilation of gcc optimizing code by platform and cpu. Use this if the optimization causes problems. Typically if you build on some non X386 compatible CPU.
Developers options    
--with-developer-flags Add additional warning flags for the compiler. This option is for developers only. It produces a flood of warnings that helps the developer to write more robust code. These warnings are normally harmless but can sometimes be a latent defect.
For more information about these flags, see CompileWithDeveloperFlags

Make

When you run make, all the C-source files are automatically compiled and linked. Just look out for error messages.

Make uses a file called "Makefile" which is generated by the "configure" script you just ran. If you have special needs you can manually edit this file. Next time you run configure a new Makefile will be generated and your changes are lost.

ALERT! Attention!

If you have run make before, you should run a make clean before running make again. This cleans out all the object files that were generated the previous time you ran make. If you do not run make clean first before you rebuild Motion you may not get the additional feature included. For example: If you built Motion without ffmpeg support and then add it later - and rebuild Motion without running make clean first - the ffmpeg feature does not get compiled into the Motion binary.

First time you build motion run ./configure, make, make install. If you need to build it again (to run with different configure options) run ./configure, make clean, make, make install.

Make Install

make install simply copies all the nice files that were generated during the compilation/linking that make did.

Makes the directories (if they do not already exist)(path shown are the defaults): /usr/local/bin, usr/local/man/man1, /usr/local/etc, /usr/local/share/doc/motion-3.2.X, and /usr/local/share/doc/examples/motion-3.2.X.

Copies the following files from the base motion directory (assuming the default PREFIX /usr/local was used when running configure - otherwise adjust to the actuals you chose)

  • Executable binary "motion" to /usr/local/bin
  • Manual page "motion.1" to /usr/local/man/man1
  • Document files "CHANGELOG, COPYING, CREDITS, INSTALL, and README to /usr/local/share/doc/motion-3.2.X
  • Example configuration files "*.conf" to /usr/local/share/doc/examples/motion-3.2.X
  • Configuration file "motion-dist.conf" to /usr/local/etc
Note that the any existing files are overwritten. The default config file motion-dist.conf is named like this so that you do not get your working motion.conf file overwritten when you upgrade Motion.

Un-install

From the motion base installation directory you simply run make uninstall

And delete the base installation directory in /usr/local and any link pointing to it. If you have forgotten where you installed it or someone else did it for you, simply search for the files and directories starting with motion. If the filenames and the directories match the names described in the "Make Install" section of this document, you can safely delete them.

Additional Make Options

The make command can be run with several options. make, make install and make uninstall has already been described above.

make clean
deletes all the binary files (object files) and the motion binary generated by make. It also deletes temporary files and any jpg files that motion has saved in the motion source directory. It is very important to always run make clean before you run make if you change the configuration (like adding features such as ffmpeg) and rebuild motion.

make distclean
deletes the files: config.status, config.log, config.cache, Makefile, and motion.spec.

make updateguide
fetches a fresh new copy of this guide and place it in your motion source directory. Note that the pictures are not downloaded.

make dist
performs make clean, make distclean and make updateguide in one single operation.

Upgrading From Older Version

If you are upgrading from motion 3.0.X or from an older version of 3.1.X you should note that many options have been removed from version 3.1.13 and forward and many new have arrived. You still have most of the old features. The options have been changed for two reasons. New more flexible features and to simplify getting started with Motion. With 3.2.1 the changes are significant. You should also note these major differences.
  • The use of thread files has completely changed. Read the section "The Config Files" carefully.
  • The mask file format has changed. Read the section about "Mask File"
  • Pre_capture feature introduced in 3.1.12
  • Advanced filename feature enables very flexible filename definitions (3.1.13)
  • onffmpegclose options enables running external scripts when mpeg file is closed (3.1.13)
  • despeckle feature improves motion detection and noise immunity (3.1.13)
  • Minimum_motion_frames feature prevents short noise events from being saved (3.1.14)
  • If you use the database features you need to note that from version 3.1.15 and forward the fields have been redefined. Removed are second, minute, hour, day, month and year. Instead these six have been replaced by a real timestamp field called time_stamp. The relatively new field 'type' has been renamed to 'file_type' to avoid reserved SQL words. A new field 'text_left' has been added which stores the text given by the config option text_left. And last a field called 'camera' has been added which stores the thread number.
  • From 3.1.15 the ffmpeg feature now also supports mpeg4 and msmpeg4. The build process of Motion now use ffmpeg libraries as shared libraries. The --with-libavcodec has been replaced by a --with-ffmpeg which only needed to specify if you are installing ffmpeg from sources in a non-standard location. If you have installed ffmpeg from sources already you will need to rebuild by running (from within the ffmpeg source file root) ./configure --enable-shared followed by make and make install. If you had installed ffmpeg from a binary RPM or deb you probably don't have to do anything.
  • Rotate feature was introduced in 3.1.15
  • Berkeley mpeg feature has been removed in 3.1.18 (use ffmpeg - it is much better)
  • Incomplete prediction feature was removed in 3.1.18. (lack of interest in finishing it)
  • Smart Mask feature introduced in 3.1.18
  • output_normal can now also have the value "first" which means only save first jpg from each event (3.1.18)
  • ffmpeg-0.4.9 is now supported. Motion detection mpegs can no longer be saved as mpeg1 (ffmpeg does not support non-standard framerates in 0.4.9) (3.1.18)
  • Motion now supports most (not all) mjpeg streaming cameras (3.1.18).
  • output_normal can now have values "first" or "best". It is used when you need to present a link to an mpeg movie shown as a single jpeg image. "First" saves the first picture frame in the new event. "Best" saves the picture frame with most motion content (most changed pixels) when the event is over. "on" still saves all motion detection picture frames plus pre and post captured images. With "best" you can set jpeg_filename = "preview" and it gets the same filename as the mpeg file but with extension .jpg. Option "locate" can also take the value "preview" which makes it only draw a rectangel on the jpeg but not on the mpeg movie. (3.2.1)
  • The xmlrpc remote control interface is replaced by a much nicer http remote control interface. (3.2.1)
  • All the options that calls external programs have been made much more generic. New onxxxx options have been added. Execute, sms and mail have been replaced by the generic on_event_start. (3.2.1)
  • New setup mode makes setting all the detection options much easier.
  • netcam now also supports proxies (3.2.2) and ftp (3.2.4)
  • text on the pictures can be set to double size (3.2.2)
  • Tracking with Logitech Sphere/Orbit improved (3.2.4)
  • SQL database feature is now fully configurable so you can control which fields you have in the database.
  • Many new conversion specifiers have been added which can be used both in filenames, commands, text, and SQL database features (3.2.2-3.2.4)
  • Stepper motor tracking feature extended to also include a Y axis (3.2.5)
  • ffmpeg_filename has been renamed to movie_filename to prepare for alternative implementation to mpeg files made with ffmpeg (3.2.5)
  • New feature: ffmpeg_deinterlace which can de-interlace using the ffmpeg libs (3.2.5)
  • New feature: minimum_frame_time which enables Motion to run at frame rates below 2. minimum_gap feature was removed since this was useless and the new minimum_frame_time feature replaces it with much better function. (3.2.7)
  • New feature: process_id_file which writes a PID file when started and removes it when stopped (3.2.7)
  • V4L2 support with many new supported palettes : V4L2_PIX_FMT_SBGGR8, V4L2_PIX_FMT_SN9C10X, V4L2_PIX_FMT_JPEG, V4L2_PIX_FMT_UYVY (3.2.8)
  • ffmpeg_video_codec allow swf (3.2.8)
  • V4L2 fix support for : V4L2_PIX_FMT_MJPEG (3.2.9)
  • ffmpeg_video_codec allow flv and ffv1(3.2.9)

Running Motion

Important Definitions

Motion is invoked from the command line. It has no GUI. Everything is controlled from config files. From version 3.2 the command line is only used to define location of config file and a few special runtime modes (setup and non-daemon).

A few important definitions.

  • A snapshot is a picture taken at regular intervals independently of any movement in the picture.
  • A "motion" image/mpeg shows the pixels that have actually changed during the last frames. These pictures are not very useful for normal presentation to the public but they are quite useful for testing and tuning and making mask files as you can see exactly where motion sees something moving. Motion is shown in greytones. If labelling is enabled the largest area is marked as blue. Smart mask is shown in read.
  • A "normal" image is the real image taken by the camera with text overlayed.

The Config Files

If Motion was invoked with command line option -c pathname Motion will expect the config file to be as specified. When you specify the config file on the command line with -c you can call it anything.

If you do not specify -c or the filename you give Motion does not exist, Motion will search for the configuration file called 'motion.conf' in the following order:

  1. Current directory from where motion was invoked
  2. Then in a directory called '.motion' in the current users home directory (shell environment variable $HOME). E.g. /home/goofy/.motion/motion.conf
  3. The directory defined by the --sysconfdir=DIR when running .configure during installation of Motion
    (If this option was not defined the default is /usr/local/etc/)
If you have write access to /usr/local/etc then the editor recommends having only one motion.conf file in the default /usr/local/etc/ directory.

Motion has a configuration file in the distribution package called motion-dist.conf. When you run 'make install' this file gets copied to the /usr/local/etc directory.

The configuration file needs to be renamed from motion-dist.conf to motion.conf. The original file is called motion-dist.conf so that your perfectly working motion.conf file does not accidentally get overwritten when you re-install or upgrade to a newer version of Motion.

If you have more than one camera you should not try and invoke Motion more times. Motion is made to work with more than one camera in a very elegant way and the way to do it is to create a number of thread config files. Motion will then create an extra tread of itself for each camera. If you only have one camera you only need the motion.conf file. The minute you have two or more cameras you must have one thread config file per camera besides the motion.conf file.

So if you have for example two cameras you need motion.conf and two thread config files. Total of 3 config files.

An option that is common to all cameras can be placed in motion.conf. (You can also put all parameters in the thread files but that makes a lot of editing when you change a common thing).

An option that is unique to a camera must be defined in each thread file.

It is often seen that people copy the entire motion.conf into the thread config files and change a few options. This works but it not recommended because it is more difficult to maintain and overview. Keep all the common options in motion.conf and the few unique only in the thread config files

The first camera is defined in the first thread file called from motion.conf. The 2nd camera is defined in the 2nd thread file called from motion.conf etc.

Any option defined in motion.conf will be used for all cameras except for the cameras in which the same option is defined in a thread config file.

Motion reads its configuration parameters in the following sequence. If the same parameter exists more than one place the last one read wins.

  1. Motion reads the configuration file motion.conf from the beginning of the file going down line by line.
  2. If the option "thread" is defined in motion.conf, the thread configuration file(s) is/(are) read.
  3. Motion continues reading the rest of the motion.conf file. Any options from here will overrule the same option previously defines in a thread config file.
  4. Motion reads the command line option again overruling any previously defined options.
So always call the thread config files in the end of the motion.conf file. If you define options in motion.conf AFTER the thread file calls, the same options in the thread files will never be used. So always put the thread file call at the end of motion.conf.

Nearly all config options can be unique for a specific camera and placed in a thread config file. There are a few options that must be in motion.conf and cannot be in a thread config file: control_authentication, control_html_output, control_localhost, control_port, daemon, and thread.

If motion is built without specific features such as ffmpeg, mysql etc it will ignore the options that belongs to these features. You do not have to remove them or comment them out.

If you run the http control command http://host:port/0/config/writeyes, motion will overwrite motion.conf and all the thread.conf files by autogenerated config files neatly formatted and only with the features included that Motion was built with. If you later re-build Motion with more features or upgrade to a new version, you can use your old config files, run the motion.conf.write command, and you will have new config files with the new options included all set to their default values. This makes upgrading very easy to do.

Command Line Options

ALERT! In Motion 3.2.1 and forward most command line options have been removed and replaced them by an option to specify location to motion.conf and a few options related to setting up motion. There are now only few command line options left and they are basically all new.

SYNOPSIS 

motion [ -hns ] [ -c config file path]

Option Description Editors comment
-n Run in non-daemon mode. Instead of running Motion in the background Motion runs in the terminal window writing messages when things happen. If you have problems getting Motion to start or work, run Motion in this mode to get more messages that can help you solve the problem.
-s Run in setup mode. Also forces non-daemon mode
-c config file path Full path and filename of config file. E.g. /home/kurt/motion.conf. Default is /usr/local/etc unless specified differently when building Motion. Many RPMs and debian packages will most likely use /etc or /etc/motion as default
-h Show help screen.  
-d level Debugging mode This mode is used for developers to enable debug messages. Normal users will not need to use this mode unless a developer request to get additional information in the attempt to resolve a bug. Mainly the netcam code has debugging features. The level defines how much debugging info you get. A high number displays all debugging.
-p process_id_file Full path of process ID file Full path and filename of process id file (PID file). This is optional. If none is given as command line option or in motion.conf (process_id_file) Motion will not create a PID file.

Config File Options

These are the options that can be used in the config file.

All number values are integer numbers (no decimals allowed). Boolean options can be on or off.

Some configuration options are only used if Motion is built on a system that has the matching software libraries installed (MySQL, PostgreSQL and FFMPEG).

MySQL

  • mysql_db, mysql_host, mysql_user, mysql_password

PostgreSQL

  • pgsql_db, pgsql_host, pgsql_user, pgsql_password, pgsql_port

FFMPEG (libavcodec)

  • ffmpeg_cap_new, ffmpeg_cap_motion, ffmpeg_filename, ffmpeg_timelapse, ffmpeg_timelapse_mode, ffmpeg_bps, ffmpeg_variable_bitrate, ffmpeg_video_codec

Options in Alphabetical Order.

Signals (sent with e.g. kill command)

A signal can be sent from the command line by typing e.g. kill -s SIGHUP pid, where the last parameter is the process ID which you get by typing ps -ef ¦ grep motion. The PID is the first on the list which is the parent process for the threads. Motion responds to the following signals:

Signal Description Editors comment
SIGHUP The config file will be reread. This is a very useful signal when you experiment with settings in the config file.
SIGTERM If needed motion will create an mpeg file of the last event and exit  
SIGUSR1 Motion will create an mpeg file of the current event.  

Error Logging

Motion reports errors to the console when it runs in non-daemon mode. And it outputs even more information when run in setup mode.

Error logging has been implemented so that errors during daemon (background) mode are logged in the syslog.

The syslog is in most Linux systems the file /var/log/messages (e.g. RedHat/Fedora) or /var/log/syslog and /var/log/user.log (e.g. Debian).

Motion Guide - Basic Features

Capture Device Options - The Basic Setup

Before you can start using motion you need to know some basics about your camera. Either you have a camera connected directly to your computer. In this case it is a video4linux type of camera. Or you connect to a network camera using a normal web URL.

video4linux (V4L) devices

You need to install your camera with the right driver. It is out of scope of this document to tell you how to do this and it depends on which type of camera.

Once installed the camera(s) will have the device names /dev/video0, /dev/video1, /dev/video2...

FreeBSD has a different naming of devices. When you build Motion for FreeBSD the default device name is /dev/bktr0. Under FreeBSD a TV card has a special device for controlling the tuner (e.g. /dev/tuner0). The option tunerdevice is only valid when Motion is built and running under FreeBSD. For Linux do not include this option in the config file (remove or comment out).

USB cameras take a lot of bandwidth. A USB camera connected to a USB 1.1 port or hub consumes all the bandwidth. Even with a small framesize and low framerate you should not expect to have more than one camera per USB 1.1 controller. If you need more than 1 USB camera add extra USB PCI cards to your computer. There exists cards that have 4 inputs each with their own controller and with full bandwidth. Many 4-input cards only have 1 controller. USB cameras do not have the feature of selecting input channels. To disable the input selection the option input must be set to the value 8 for USB cameras.

Composite video cards are normally made with a chip called BT878 (older cards have a BT848). They all use the Linux driver called 'bttv'.

There are cards with more then one video input but still only one BT878 chip. They have a video multiplexer which input is selected with the config option input. Input channel numbers start at 0 (which is why the value 8 and not 0 disables input selection). There are video capture cards available with 4 or 8 inputs but only one chip. They present themselves as one single video device and you select input using the 'input' option. If you define e.g. 4 thread config files with the same videodevice name but different input numbers Motion automatically goes into round robin mode. See the round robin section for more information. Many TV tuner cards have the input channels: TV Tuner = 0, Standard composite video = 1, S-VHS = 3. Other have TV=0, composite video 1= 1, composite video = 2, S-VHS = 3. For video capture cards input 1 is normally the composite video input.

Some capture cards are specially made for surveillance with for example 4 inputs. Others have a TV tuner, a composite input (phono socket) and perhaps also a S-VHS input. For all these cards the inputs are numbered. The numbering varies from card to card so the easiest is to experiment for 5 minutes with a program that can show the videostream. Use a program such as Camstream or xawtv to experiment with the values.

If you use the TV tuner input you also need to set the frequency of the TV channel using the option frequency. Otherwise set 'frequency' to 0.

Finally you need to set the TV norm. Values: 0 (PAL), 1 (NTSC), 2 (SECAM), 3 (PAL NC no colour). Default is 0 (PAL). If your camera is a PAL black and white you may get a better result with norm=3 (PAL no colour).

If the netcam_url option is defined all the video4linux options are ignored so make sure the netcam_url option is commented out if you do not need it.

These are the parameters used for video4linux devices

auto_brightness

  • Type: Boolean
  • Range / Valid values: on, off
  • Default: off
  • Option Topic

Let motion regulate the brightness of a video device. Only recommended for cameras without auto brightness

Motion will try to adjust the brightness of the video device if the images captured are too dark or too light. This option will be most useful for video devices like web cams, which sometimes don't have such an option in hardware.

The auto_brightness feature will adjust the brightness of the device up or down until the value defined by the option brightness is reached (1 = dark, 255 = bright). If brightness is zero auto_brightness will try to adjust to the average brightness level 128.

You need to know if the camera supports auto brightness. Most cameras have auto everything. If your video device already does this for you this option might cause oscillations. If you do not know assume that it has and do not use the Motion auto brightness feature. At least not to start with.

brightness

  • Type: Integer
  • Range / Valid values: 0 - 255
  • Default: 0 (disabled)
  • Option Topic

The brightness level for the video device.

Value 0 means that Motion does not set the brightness value but leaves it unchanged.

If this setting is used in conjunction with the auto_brightness feature then this setting is the average brightness level in the range 1 (dark) to 255 (bright) that the auto_brightness feature will try to achieve by adjusting the device brightness up and down.

contrast

  • Type: Boolean
  • Range / Valid values: 0 - 255
  • Default: 0 (disabled)
  • Option Topic

The contrast level for the video device.

Disabled (Value 0) means that Motion does not set the contrast value.

framerate

  • Type: Integer
  • Range / Valid values: 2 - 100
  • Default: 100 (no limit)
  • Option Topic

Maximum number of frames to be captured from the camera per second.

The faster you fetch pictures from the camera the more CPU load you get and the more pictures get included when Motion is detected.

Motion will stop storing pictures if the framerate is set to less than 2.

Set this parameter to the maximum number of images per second that you want to store either as images or as mpeg films.

To set intervals longer than one second use the 'minimum_gap' option instead.

frequency

  • Type: Boolean
  • Range / Valid values: 0 - 999999
  • Default: 0 (Not set)
  • Option Topic

The frequency to set the tuner to (kHz). Valid range: per tuner spec, default: 0 (Don't set it)

This option is only relevant if you have a TV tuner card where you can select the tuner frequency. Your tuner card must support this feature.

height

  • Type: Integer
  • Range / Valid values: Device Dependent
  • Default: 288
  • Option Topic

The height of each frame in pixels.

The height of the image in pixels. Motion does not scale so should be set to the actual size of the v4l device. In case of a net camera motion sets the height to the height of the first image read.

Motion actually set the size of the image coming from the video4linux device.

Your camera or capture/TV card will not support any picture size. You must know which frame size (width and height) the camera supports. If you do not know start with width 320 and height 240 which most cameras and capture cards supports.

For some device drivers like pwc (driver for Philips USB cameras) setting the size to a non-standard value makes the driver create an image of the nearest smaller size and create a gray band around the image to fit the size given by motion. Note that it is the driver and not motion that generates the gray band. Motion will try to detect motion in the entire image including the gray band.

Motion requires that dimensions of camera image must have both height and width that are a multiple of 16. Thís is normally not a problem. All standard sizes like 640, 480, 352, 320, 288, 240, ...etc are multiples of 16.

hue

  • Type: Integer
  • Range / Valid values: 0 - 255
  • Default: 0 (disabled)
  • Option Topic

The hue level for the video device.

Normally only relevant for NTSC cameras.

input

  • Type: Integer
  • Range / Valid values: 0 - 7, 8 = disabled
  • Default: 8 (disabled)
  • Option Topic

Input channel to use expressed as an integer number starting from 0. Should normally be set to 1 for video/TV cards, and 8 for USB cameras.

This parameter is really used only with video capture cards that has more than one input.

However if you set the input number to e.g. 1 for a USB camera (ov511 or pwc driver) motion writes an error message back. If you set it to 8 it does not give you any warning.

If you have a video capture card you can define the channel to tune to using this option. If you are using a USB device, network camera or a capture card without tuner you should set the value to the default 8.

Many TV tuner cards have the input channels: TV Tuner = 0, Standard composite video = 1, S-VHS = 3. Other have TV=0, composite video 1= 1, composite video = 2, S-VHS = 3. It is recommended to set the parameter to 8 for USB cameras as your first try. For video capture cards input 1 is normally the composite video input.

minimum_frame_time

  • Type: Integer
  • Range / Valid values: 0 - 2147483647
  • Default: 0
  • Option Topic

Minimum time in seconds between the capturing picture frames from the camera. Default: 0 = disabled - the capture rate is given by the camera framerate.

This option is used when you want to capture images at a rate lower than 2 per second.

When this is enabled the framerate option is used only to set the pace the Motion service the webcam port etc. Running Motion at framerate 2 is normally fine.

ALERT! This feature is introduced in Motion 3.2.7

norm

  • Type: Discrete Strings
  • Range / Valid values: 0 (PAL), 1 (NTSC), 2 (SECAM), 3 (PAL NC no colour)
  • Default: 0 (PAL)
  • Option Topic

Select the norm of the video device. Values: 0 (PAL), 1 (NTSC), 2 (SECAM), 3 (PAL NC no colour). Default: 0 (PAL)

This value is only used for capture cards using the BTTV driver.

rotate

  • Type: Discrete Strings
  • Range / Valid values: 0, 90, 180, 270
  • Default: 0 (not rotated)
  • Option Topic

Rotate image the given number of degrees. The rotation affects all saved images as well as mpeg movies.

The rotation feature is used when the camera is hanging upside down (180 degrees) or if you choose a picture format in portrait instead of the normal landscape (90 or 270 degrees).

Note that the CPU load increases when using this feature with a value other than 0. Also note that Motion automatically swaps width and height if you rotate 90 or 270 degrees, so you don't have to touch these options.

saturation

  • Type: Integer
  • Range / Valid values: 0 - 255
  • Default: 0 (disabled)
  • Option Topic

The colour saturation level for the video device.

tunerdevice

  • Type: String
  • Range / Valid values: Max 4095 characters
  • Default: /dev/tuner0
  • Option Topic

The tuner device used for controlling the tuner in a tuner card. This option is only used when Motion is compiled for FreeBSD.

Make sure to remove or comment out this option when running Motion under Linux.

videodevice

  • Type: String
  • Range / Valid values: Max 4095 characters
  • Default: /dev/video0 (FreeBSD: /dev/bktr0)
  • Option Topic

The video device to be used for capturing. Default for Linux is /dev/video0. for FreeBSD the default is /dev/bktr0.

This is the video4linux device name. Ignore this for net cameras.

width

  • Type: Integer
  • Range / Valid values: Device Dependent
  • Default: 352
  • Option Topic

The width in pixels of each frame. Valid range is camera dependent.

Motion does not scale so should be set to the actual size of the v4l device.

In case of a net camera motion sets the height to the height of the first image read.

Motion actually set the size of the image coming from the video4linux device.

Your camera or capture/TV card will not support any picture size. You must know which frame size (width and height) the camera supports. If you do not know start with width 320 and height 240 which most cameras and capture cards supports.

For some device drivers like pwc (driver for Philips USB cameras) setting the size to a non-standard value makes the driver create an image of the nearest smaller size and create a gray band around the image to fit the size given by motion. Note that it is the driver and not motion that generates the gray band. Motion will try to detect motion in the entire image including the gray band.

Motion requires that dimensions of camera image must have both height and width that are a multiple of 16. Thís is normally not a problem. All standard sizes like 640, 480, 352, 320, 288, 240, ...etc are multiples of 16.

Network Cameras

Motion can connect to a network camera through a normal TCP socket. All you need to give it is the URL. The URL given must return either one single jpeg picture or an mjpeg stream. For the time being Motion cannot connect to a video stream such a mpeg, mpeg4, divx. The URL must return one single jpeg image or an mjpeg stream! You can connect through a proxy server.

Also watch out that you do not use a URL that create an HTML page with an embedded jpg. What must be returned is the jpg picture itself or the raw mjpeg stream.

When the netcam_url is defined all the video4linux options above are ignored!!

If the connection to a network camera is lost - Motion will reuse the last good image for approx 30 seconds. AFter 30 seconds the image is replaced by a grey image with a text telling that the signal is lost and when the connection was lost. This text and its date format is not configurable and there are no plans to make it configurable in order to keep the number config options under control.

Note that Motion requires that dimensions of camera image must have both height and width that are a multiple of 16. Thís is normally not a problem. All standard sizes like 640, 480, 352, 320, 288, 240, ...etc are multiples of 16. But if you intend to monitor a network camera which is saving jpeg images you may have to pay attention to the dimensions of the picture.

The network camera feature has been completely re-written in Motion 3.2.2. We believe the netcam feature is much more stable now that it was in previous versions. Motion tries to reconnect to the camera if the connection is lost. There is no official standard for mjpeg and we know that there are probably still some cameras that are not yet supported. If you run into a problem please file a Bug Report with as much information about the format as possible. A binary raw dump of the first 2-3 frames with headers and boundary strings is very useful. You can see how to make it on the special topic NetcamMjpegStreamDumps. When you have the file you can upload it to the same topic.

netcam_proxy

  • Type: String
  • Range / Valid values: Max 4095 characters
  • Default: Not defined
  • Option Topic

URL to use for a netcam proxy server, if required. The syntax is http://myproxy:portnumber

Use this if you need to connect to a network camera through a proxy server.

Example of syntax: "http://myproxy.mydomain.com:1024

If the proxy port number is 80 you can ommit the port number. Then the syntax is use "http://myproxy.mydomain.com" .

Leave this option undefined if you do not use a proxy server.

netcam_url

  • Type: String
  • Range / Valid values: Max 4095 characters
  • Default: Not defined
  • Option Topic

Specify an url to a downloadable jpeg file or raw mjpeg stream to use as input device. Such as an AXIS 2100 network camera.

Example of URL: http://www.gate.com/pe1rxq/jeroen.jpg.

Motion can connect to a network camera through a normal TCP socket. All you need to give it is the URL. The URL given must return either one single jpeg picture or an mjpeg stream. For the time being Motion cannot connect to a video stream such a mpeg, mpeg4, divx. The URL must return one single jpeg image or an mjpeg stream!

Also watch out that you do not use a URL that create an HTML page with an embedded jpg. What must be returned is the jpg picture itself or the raw mjpeg stream.

When the netcam_url is defined all the video4linux options are ignored!!

Motion can also fetch jpeg pictures via ftp. You then use the ftp:// syntax instead.

netcam_userpass

  • Type: String
  • Range / Valid values: Max 4095 characters
  • Default: Not defined
  • Option Topic

For network cameras protected by username and password, use this option for HTTP 1.1 Basic authentication. The string is specified as username:password. Do not specify this option for no authentication.

To use no authentication simply remove this option from the config file comment it out with "#" or ";" in front.

Round Robin feature

This feature is automatically activated where multiple threads are sharing the same video device (for example /dev/video0). Each thread can then set different input channels to change camera with the input option or by tuning the tuner with frequency option.

ALERT! Round Robin is not relevant for Network cameras or standard USB web cameras. The Round Robin feature is used with video capture cards which have multiple inputs per video chip.

ALERT! Note that round robin is not the ideal way to run multiple cameras. When the capture card changes input it takes a little while before the decoder chip has syncronized to the new camera. You can improve this if you have expensive cameras with a syncronize input. Only one camera can be decoded at a time so if you have 4 cameras connected 3 of the camera threads will need to wait for their turn. The fact that cameras have to take turns and the fact that you have to skip a few frames after each turn dramatically lowers the possible framerate. You can get a high framerate by viewing each camera for a long time. But then you may miss the action on one of the inactive cameras. If you can affort it avoid Round Robin and buy the more expensive type of capture cards that has one decoder chip per input. If you only need 2 or 3 cameras you can also simply put 2 or 3 cheap TV cards in the computer. Linux has no problem working with multiple TV cards.

  • If multiple threads use the same video device, they each can capture roundrobin_frames number of frames before having to share the device with the other threads.
  • When another thread wants to watch another input or frequency or size the first roundrobin_skip number of frames are skipped to allow the device to settle.
  • The last option switch_filter is supposed to prevent the change of camera from being detected as Motion. Its function is not perfect and sometimes prevents detection of real motion. You should start with having the option disabled and then try with the option enabled to see if you can skip less frames without loosing the detection of the type of motion you normally want to detect.

These are the special Round Robin options

roundrobin_frames

  • Type: Integer
  • Range / Valid values: 1 - 2147483647
  • Default: 1
  • Option Topic

Specifies the number of frames to capture before switching inputs, this way also slow switching (e.g. every second) is possible.

The Round Robin feature is automatically activated where multiple threads are sharing the same video device. Each thread can then set different input channels or frequencies to change camera.

If multiple threads use the same video device, they each can capture roundrobin_frames number of frames before having to share the device with the other threads.

roundrobin_skip

  • Type: Integer
  • Range / Valid values: 1 - 2147483647
  • Default: 1
  • Option Topic

Specifies the number of frames to skip after a switch. (1 if you are feeling lucky, 2 if you want to be safe).

The Round Robin feature is automatically activated where multiple threads are sharing the same video device. Each thread can then set different input channels or frequencies to change camera.

When another thread wants to watch another input or frequency or size the first roundrobin_skip number of frames are skipped to allow the device to settle.

switchfilter

  • Type: Boolean
  • Range / Valid values: on, off
  • Default: off
  • Option Topic

Turns the switch filter on or off. The filter can distinguish between most switching noise and real motion. With this you can even set roundrobin_skip to 1 without generating much false detection.

This is a round robin related feature used when you have a capture card with multiple inputs (controlled by the 'input' option) on the same videodevice.

ALERT! This feature was seriously broken until Motion 3.2.4

Motion Detection Settings

These are the options that controls the detection of motion. Further details follows after.

despeckle

  • Type: String
  • Range / Valid values: EedDl
  • Default: Not defined
  • Option Topic

Despeckle motion image using combinations of (E/e)rode or (D/d)ilate. And ending with optional (l)abeling.

A way of tuning (by removing or enhancing) noise in the motion image. Options for the despeckle feature are any of 'e', 'E', 'd' or 'D'. This can be combined by a trailing 'l' (letter l) which enables the labeling feature. Default: Not Defined (Don't despeckle and label).

Wind blowing grass and trees around or poor light conditions can cause a lot of dots (or noise) to appear in the motion image (See the section on Tuning Motion). This feature removes (or enhances!) this noise and so improves the reliability of motion.

The 'e' option removes diamonds, 'E' removes squares and alternating eE will remove circles. Each e/E you add will shrink the noise by a pixel all the way around. So 'despeckle Ee' will remove circles of radius 2. However, this will also shrink the detection by 2 and will affect the threshold. So to remove noise and then restore the detected motion to its original size try 'despeckle EedD'.

After the despeckle feature is done you can let the labeling feature search for areas of connected pixels and "label" each area. The program will now trigger motion based on the number of changed pixels in the largest area. In other words, the largest labeled area has to be above the threshold to trigger a motion detected.

The value EedDl is a good starting point. The possible combinations are endless and it requires many experiments to find the best combination. Just remember that the labeling feature only works as intended if it runs after the despeckle feature. Ie. the letter 'l' must be the last letter and only one 'l'.

If you have very few problems with false detections leave this option either blank or at EedD which will remove most of the single pixel noise. A very detailed technical explanation of the despeckle part can be found at the webpage of the author of this feature Ian McConnell's Webcam: Motion Web Page

gap

  • Type: Integer
  • Range / Valid values: 0 - 2147483647
  • Default: 60
  • Option Topic

Gap is the seconds of no motion detection that triggers the end of an event. An event is defined as a series of motion images taken within a short timeframe.

Recommended value is 60 seconds (Default). The value 0 is allowed (but not recommended) and disables events causing all Motion to be written to one single mpeg file and no pre_capture. You can force an event to end and a new to begin using the http control 'http://host:port/thread_number/action/makemovie'. Disabling events has bad side effects on noise_tune and smartmask. Both features can only work properly outside an event. When gap is set to 0, both features don't work properly anymore.

An event is defined as a series of motion images taken within a short timeframe. E.g. a person walking through the room is an event that may have caused 10 single jpg images to be stored. This option defines how long a pause between detected motions that is needed to be defined as a new event.

The gap timer starts after the last motion is detected and post_capture images have been saved and appended to open movie mpeg files.

Any motion detected before the gap timer times out resets the gap timer so it starts counting over again.

Detailed Description

The option 'gap' is important. It defines how long a period of no motion detected it takes before we say an event is over. An event is defined as a series of motion images taken within a short timeframe. E.g. a person walking through the room is an event that may have caused 10 single jpg images to be stored. Motion detected includes post_captured frames set by the 'post_capture' option. The 'gap' option defines how long a pause between detected motions that is needed to be defined as a new event. A good starting value is 60 seconds.

The way 'gap' works in more technical terms is:

  • Gap is a timer that timeout 'gap' seconds after the last video frame with motion is detected.
  • If 'post_capture' is activated then the gap timer starts counting after the last image of the post_capture buffer has been saved.
  • The gap timer is reset and starts all over each time new motion is detected, so you will not miss any action by having a short 'gap' value. It will just create more events (e.g. more mpegs files)

The gap value impacts many functions in Motion.

  • When the gap timer runs out the event number is increased by one next time motion is detected. When you use the %v conversion specifier in filenames or text features this means that the number in filename or text increased by one.
  • The pre_capture feature only works at the beginning of an event. So if you have a very large 'gap' value pre_capture is not working very often.
  • When you make mpegs using the ffmpeg features a new mpeg file is started at the beginning of an event when the first motion is detected. When 'gap' seconds has passed without motion (and post_captured frames saved) the mpeg files is completed and closed.
  • Do not use large gap values to generate one large mpeg4 file. If Motion stops working this mpeg4 file never gets properly completed and closed and you will not be able to view it.
  • Some of the tracking features sets the camera back to the center position when an event is over.

Note that 'gap' and 'minimum_gap' have nothing to do with each other.

lightswitch

  • Type: Integer
  • Range / Valid values: 0 - 100
  • Default: 0 (disabled)
  • Option Topic

Ignore sudden massive light intensity changes given as a percentage of the picture area that changed intensity.

Experiment to see what works best for your application.

Note: From version 3.1.17 (snap release 2 and on) this option has changed from a boolean (on or off) to a number in percent between 0 and 100. Zero means the option is disabled.

The value defines the picture areas in percent that will trigger the lightswitch condition. When lightswitch is detected motion detection is disabled for 5 picture frames. This is to avoid false detection when light conditions change and when a camera changes sensitivity at low light.

low_cpu

  • Type: Integer
  • Range / Valid values: 0 - 100
  • Default: 0 (disabled)
  • Option Topic

When this option is not zero motion will be in a low cpu mode while not detecting motion. In low cpu mode Motion reduces the framerate to the value given for this option. Value zero means disabled.

This is smart for running a server that also does other tasks such as running Apache, MySQL etc. Motion grabs this lower number of frames per second until it detects motion. Then it speeds up to normal speed and take pictures as set by the option "framerate".

mask_file

  • Type: String
  • Range / Valid values: Max 4095 characters
  • Default: Not defined
  • Option Topic

PGM file to use as a sensitivity mask. This picture MUST have the same width and height as the frames being captured and be in binary format.

Full path of the PGM (portable gray map) mask file (binary format).

If you have one or more areas of the camera image in which you do NOT want motion detected (e.g. a tree that moves in the wind or a corner of the picture where you can see cars/pedestrians passing by) you need a mask file. This file is a picture that you create in your favorite photo editing program. The areas that you want detected must be white. The error that you want ignored must be black. The pgm image must be the same size (number of pixels high and wide) as the pictures that are taken by the camera (video4linux device).

You can adjust sensitivity by using gray tones.

If you do not have a mask file disable this option by not having it in the config file or comment it out ("#"or ";" as first character in line). If you are using the rotate option, note that the mask is applied after the rotation.

Detailed Description

The mask file must be a pgm format image file (portable gray map). Note that you must choose the BINARY format.

The feature is simple. Create an image of exact the same size as the ones you get from your video device (camera). Make a purely white picture and paint the areas that you want to mask out black. You can also make gray areas where you want to lower the sensitivity to motion. Normally you will stick to pure black and white.

One easy method for generating the mask file is as follows.

You can just take a motion captured picture, edit it with black and white for the mask and save it as a pgm file. If you cannot save in this format save as a grayscale jpg and then you can convert it to pgm format with

djpeg -grayscale -pnm [inputfile] > mask.pgm

(assuming you have djpeg installed - part of the jpeg lib package).

Note that the mask file option masks off the detection of motion. The entire picture is still shown on the picture. This means that you cannot use the feature to mask off an area that you do not want people to see.

Below are an example of a webcam picture and a mask file to prevent the detection cars in the street.

Normal picture. Notice the street is visible through the hedge.

max_mpeg_time

  • Type: Integer
  • Range / Valid values: 0 (infinite) - 2147483647
  • Default: 3600
  • Option Topic

The maximum length of an mpeg movie in seconds. Set this to zero for unlimited length.

minimum_gap

  • Type: Integer
  • Range / Valid values: 0 - 2147483647
  • Default: 0 (no minimum)
  • Option Topic

The minimum time between two shots in seconds.

This is the minimum gap between the storing pictures while detecting motion.

The value zero means that pictures can be stored almost at the framerate of the camera. Normally you will set this to 0

This option has nothing to do with the 'gap' option.

ALERT! From motion 3.2.7 this feature has been removed because it was in practical a useless feature. It prevented saving more than one picture per minimum_gap seconds but the capturing and motion detect was still run at full framerate loading the CPU heavily. From 3.2.7 a new feature called minimum_frame_time has been introduced which lower the capture rate. So it gives the same effect as minimum_gap did but additionally lower the CPU load significantly.

minimum_motion_frames

  • Type: Boolean
  • Range / Valid values: 1 - 1000s
  • Default: 1
  • Option Topic

Picture frames must contain motion at least the specified number of frames in a row before they are detected as true motion. At the default of 1, all motion is detected. Valid range is 1 to thousands, but it is recommended to keep it within 1-5.

Note that the picture frames are buffered by Motion and once motion is detected also the first frames containing motion are saved so you will not miss anything.

The feature is used when you get many false detections when the camera changes light sensitivity or light changes.

Experiment for best setting. Even though Motion accepts large values you should set this to a relatively low number (below 10). For each step larger than 1 Motion reserves space in RAM for the picture frame buffer. If you have a large value Motion will miss many frames from the camera while it is processing the all the pictures in the buffer.

night_compensate

  • Type: Boolean
  • Range / Valid values: on, off
  • Default: off
  • Option Topic

When this option is set the noise threshold will be lowered if the picture is dark. This will improve the sensitivity in dark places. However it might also increase the number of false alarms since most cameras also increase light sensitivity with their AGC (Automatic Gain Control) and this will increase noise.

It has normally been the advice not to use this with 'noise_tune' turned on. However the latest experience is that with the new improved noise_tune algorithm it actually works fine in combination with 'night_compensate'.

noise_level

  • Type: Integer
  • Range / Valid values: 1 - 255
  • Default: 32
  • Option Topic

The noise level is used as a threshold for distinguishing between noise and motion.

This is different from the threshold parameter. This is changes at pixel level. The purpose is to eliminate the changes generated by electric noise in the camera. Especially in complete darkness you can see the noise as small grey dots that come randomly in the picture. This noise can create false motion detection. What this parameter means is that the intensity of a pixel must change more than +/- the noise threshold parameter to be counted.

noise_tune

  • Type: Boolean
  • Range / Valid values: on, off
  • Default: on
  • Option Topic

Activates the automatic tuning of noise level.

This feature makes Motion continuously adjust the noise threshold for distinguishing between noise and motion. The 'noise_level' setting is ignored when activating this feature. This is a new feature and new algorithm. It may give different results depending on camera and light conditions. Report your experience with it on the Motion mailing list. If it does not work well, deactivate the 'noise_tune' option and use the manual setting of 'noise_level' instead.

output_all

  • Type: Boolean
  • Range / Valid values: on, off
  • Default: off
  • Option Topic

Picture are saved continuously as if motion was detected all the time.

This feature is not meant to be the normal mode of operation. Especially not if you have the output_normal or output_motion features enabled since it will keep on saving pictures on the disk and you will soon run out of disk space. So be careful with this command.

If your frame rate is 10 pictures per second motion will save 10 new picture pr second until the disk is full.

It does all the normal actions that are done when motion is detected. It saves pictures on the harddisk, execute external scripts, etc as fast as the frame rate of the camera. So it is probably a good idea to run with a low framerate when using this feature and to not use activate all the features that saves files on the disk.

The idea of this feature is that you can turn the feature on and off for a short period of time to test or to generate continuous mpeg films when needed.

post_capture

  • Type: Integer
  • Range / Valid values: 0 - 2147483647
  • Default: 0 (disabled)
  • Option Topic

Specifies the number of frames to be captured after motion has been detected.

The purpose of this is mainly to create smooth video clips each time motion is detected. Use it to you personal taste (and disk space)..

This option is the preferred way to create continuous movies. Post_capture does not consume extra RAM and it does not create pauses in the movie even with large values.

If you only store mpegs movies and do not have output_normal on, then the recommended post_capture value is what is equivalent to 1-5 seconds of movie.

pre_capture

  • Type: Integer
  • Range / Valid values: 0 - 100s
  • Default: 0 (disabled)
  • Option Topic

Specifies the number of previous frames to be outputted at motion detection. Recommended range: 0 to 5, default=0. Do not use large values! Large values will cause Motion to skip video frames and cause unsmooth mpegs. To smooth mpegs use larger values of post_capture instead.

Motion buffers the number of picture frames defined by 'pre_capture'. When motion is detected the pictures in the buffer are included in the video clip generated by ffmpeg. The effect is that it seems the program knew in advance that the event was going to take place and started the recording before it actually happened. This is a nice feature that give more complete video clips of an event.

If pre_capture is set to 0 the feature is disabled. Keep this value below 5.

The recommended value would be approx 0.5 second of video so the value should be defined so it fits the framerate and the desired pre-capture time. E.g. 0.5 second at 20 frames pr second would mean a value of 5. You should never use a value larger than 10.

You can in theory have up to 100s of pre-captured frames but naturally this makes motion leave a larger footprint in the memory of the computer. More important Motion is processing all the buffered images including saving jpegs, encoding mpegs, writing to databases and executing external programs after the first image is detected as Motion.

Motion will not grab another image until this is done. This means that even moderate values for pre_capture combined with high framerates will mean that you will miss quite many frames of Motion. It is therefore recommended to use relative small values for pre_capture. Depending on your chosen framerate and depending on the features enabled values from 1-5 are sensible.

If you wish to create smooth mpegs during events using large pre_capture values will do the opposite! It will create a long pause where a lot of action is missed.

To get a smooth mpeg use a large value for post_capture which does not cost any performance hit or RAM space.

smart_mask_speed

  • Type: Integer
  • Range / Valid values: 0 - 10
  • Default: 0 (disabled)
  • Option Topic

Slugginess of the smart mask. Default is 0 = DISABLED. 1 is slow, 10 is fast.

Smartmask is a dynamic, self-learning mask. Smartmask will disable sensitivity in areas with frequent motion (like trees in the wind). Sensitivity is turned on again after some time of no more motion in this area. The built mask is a bit larger at the borders than the actual motion was. This way smartmask works more reliable when sudden moves occur under windy conditions.

smart_mask_speed - tunes the slugginess of the mask. It accepts values from 0 (turned off) to 10 (fast). Fast means here that the mask is built quick, but it is also not staying very long with no more motion. Slow means that it takes a while until the mask is built but it also stays longer. A good start value for smart_mask_speed is 5. This setting is independent from the framerate. The attack and decay time is constant over all available framerates.

When smartmask is enabled and motion is also configured to either write motion-images or motion-mpegs, the current smartmask is copied as an overlay into the black/white motion-pictures/mpegs in red colour. Same thing happens to the webcam stream when Motion runs in setup_mode. That way you can easily adjust smart_mask_speed.

Detailed Description

The mask_file option provides a static mask to turn off sensitivity in certain areas. This is very usefull to mask a street with cars passing by all day long etc...

But imagine a scenario with large bushes and big trees where all the leaves are moving in the wind also triggering motion from time to time even with despeckle turned on. Of course you can also define a static mask here, but what if the bushes are growing during spring and summer? Well, you have to adapt the mask from time to time. What if the camera position moves slightly? What if someone grows new plants in your garden? You always have to setup a new static mask.

The answer to this problem is the smart mask feature introduced in Motion 3.1.18. A dynamic, self-learing mask.

Smart mask will disable sensitivity in areas with frequent motion (like trees in the wind). Sensitivity is turned on again after some time of no more motion in this area. The built mask is a bit larger at the borders than the actual motion. This way smartmask works more reliably when sudden moves occur under windy conditions.

threshold

  • Type: Integer
  • Range / Valid values: 1 - 2147483647
  • Default: 1500
  • Option Topic

Threshold for declaring motion. The threshold is the number of changed pixels counted after noise filtering, masking, despeckle, and labelling.

The 'threshold' option is the most important detection setting. When motion runs it compares the current image frame with the previous and counts the number of changed pixels after having processed the image with noise filtering, masking, despeckle and labeling. If more pixels than defined by 'threshold' have changed we assume that we have detected motion. Set the threshold as low as possible so that you get the motion you want detected but large enough so that you do not get detections from noise and plants moving. Note that the larger your frames are, the more pixels you have. So for large picture frame sizes you need a higher threshold.

Use the -s (setup mode) command line option and/or the text_changes config file option to experiment to find the right threshold value. If you do not get small movements detected (see the mouse on the kitchen floor) lower the value. If motion detects too many birds or moving trees, increase the number. Practical values would be from a few hundred to 2000 indoors and 1000-10000 outdoors.

threshold_tune

  • Type: Boolean
  • Range / Valid values: on, off
  • Default: off
  • Option Topic

Activates the automatic tuning of threshold level.

This feature makes Motion continuously adjust the threshold for declaring motion.

The threshold setting is ignored when activating this feature. It may give different results depending on your camera, light conditions, indoor/outdoor, the motion to be detected etc. If it does not work well, deactivate the 'threshold_tune' option and use the manual setting of threshold instead.

Image File Output

The following options controls how Motion generates images when detection motion.

output_motion

  • Type: Boolean
  • Range / Valid values: on, off
  • Default: off
  • Option Topic

Output pictures with only the moving object. This feature generates the special motion type movies where you only see the pixels that changes as a graytone image. If labelling is enabled you see the largest area in blue. Smartmask is shown in red.

Motion images shows the motion content of the pictures. This is good for tuning and testing but probably not very interesting for the general public.

Default is not to store motion images. Motion pictures are stored the same place and with the same filename as normal motion triggered pictures except they have an "m" appended at the end of the filename before the .jpg or .ppm. E.g. the name can be 01-20020424232936-00m.jpg.

output_normal

  • Type: Discrete Strings
  • Range / Valid values: on, off, first, best
  • Default: on
  • Option Topic

Normal image is an image that is stored when motion is detected. It is the same image that was taken by the camera. I.e. not a motion image like defined by output_motion. Default is that normal images are stored.

If you set the value to 'first' Motion saves only the first motion detected picture per event.

If you set it to "best" Motion saves the picture with most changed pixels during the event. This is useful if you store mpegs on a webserver and want to present a jpeg to show the content of the mpeg on a webpage. "best" requires a little more CPU power and resources compared to "first".

Set to 'off' to don't write pictures ( jpeg or ppm ).

ppm

  • Type: Boolean
  • Range / Valid values: on, off
  • Default: off
  • Option Topic

Output ppm images instead of jpeg. This uses less CPU time, but causes a LOT of hard disk I/O, and it is generally slower than jpeg.

The recommendation is to always use jpg except if you have a specific need to store high quality pictures without any quality loss. For web cameras you should always choose jpg. Note that the built in webcam server requires that this parameter is set to off.

quality

  • Type: Integer
  • Range / Valid values: 1 - 100
  • Default: 75
  • Option Topic

The quality for the jpeg images in percent.

100 means hardly compressed. A small number means a much smaller file size but also a less nice quality image to look at. 50 is a good compromise for most.

Tuning Motion

Motion 3.2 introduces a new feature Setup Mode. This is a great new feature with really make tuning all the settings of Motion much more easy and transparent. In setup mode two things happen:

  1. With 'motion -s' Motion runs in console mode instead of daemon. It outputs a lot of useful information for each frame from the camera. Each message is prefixed by [number] where number is the camera number (thread number).
  2. When you look at the mjpeg webcam stream you see a black image with numbers. What you see is the number of changed pixels, number of labeled areas and noise setting. When something moves you see the pixels detected as Motion in black and white. The largest labelled area (assuming despeckle is enabled and with the 'l' at the end) is blue. It is only the blue areas which is counted as Motion. If smartmask is enabled you see this as red areas.

Here is a suggestion how to initially setup Motion.

  • Disable despeckle (comment it out in motion.conf).
  • Disable smartmask
  • Enable both http control and webcam by setting port numbers. Example 8080 for control and 8081 for webcam.
  • Start Motion in setup mode
  • View the webcam stream. Either with Cambozola or with Firefox. http://localhost:8081/ Firefox often needs to reload the page before it works. Bug in Firefox. Internet Explorer cannot show the stream unless you make a webpage on your Apache with Cambozola applet.
  • Open new browser window and connect to the http interface. http://localhost:8080/ . You can now control and change almost anything while Motion is running. You cannot resize the image. That was too hard to code. To disable a feature enter a space.
  • Start by experimenting with noise level. Do this both during daylight and during darkness. You will be surprised to see how much noise a camera makes during night. Try using the automatic noise feature. It should work for most.
  • Now try the despeckle feature. Enable it using the recommended default EedDl. If this is not enough experiment. Remember that the l must be the last letter. It is fun to play with.
  • Set the threshold to what you want to trigger Motion.

In normal mode you can use the same setting with two browser windows and experiment with settings of the camera if needed.

From the web interface you can ask Motion to write all your changes back to the config files (motion.conf and thread config files). It will even tidy them up for you so they look nice.

There are two sets of options to adjust.

Normal picture frame

outputnormal1.jpg

Motion type picture frame with despeckle. Note that the largest area is blue and only this is counted as Motion.

The Motion image shows how Motion maintains a "reference frame" which is not just the last picture frame but a matematical calculation of the past images. This enlarges real Motion and ensures that it is not easy to sneak in slowly.

Generating MPEG films with ffmpeg

The ffmpeg option can generate mpeg films very fast and "on the fly". This means that the mpeg film is growing each time motion is detected.

Some people on the Motion mailing list have had trouble building the ffmpeg package because they did not have the NASM assembler package installed. So pay attention to this if you run into problems.

ffmpeg exists as binary packages for most distributions including RPMs and debian packages.

Ffmpeg is an interesting project. The releases have not been very consistent over time. The official releases are out of date now. So we are forced to take our chance and checkout a version from their CVS server and hope that we are lucky in getting a version that works. See ffmpeg project page. We encourage the maintaners of such an important project to introduce better release schedules in the near future for the benefit of opensource software.

In order to help people finding a version of ffmpeg that works we have started testing the Motion package with a selection of binaries and a CVS snapshot. The CVS source snapshot of ffmpeg which is certified with Motion is available on the Related projects file area on the Motion Sourceforge project

Motion works with the following versions of ffmpeg:

  • ffmpeg-0.4.8. With this release Motion supports mpeg1, mpeg4 and msmpeg4. Lately newer distributions have problems building this 2003 release of ffmpeg so many of you no longer have this option.
  • ffmpeg-0.4.9pre1. Is supported starting from Motion version 3.1.18. With this release Motion supports mpeg4 and msmpeg4 but not mpeg1. The reason is that the ffmpeg team has decided no longer to support non-standard framerates in their mpeg1 encoder library. Also ffmpeg-0.4.9pre1 gives people problems on newer distributions.
  • ffmpeg from CVS. This may work. We cannot continuously monitor and try every time a new source file is checked into ffmpeg. You will have to try.
  • ffmpeg RPMs. Currently each Motion release is tested with the current Livna ffmpeg rpm package for Fedora. See the Download Files page for direct links to the version which has been certified with the latest Motion release.
  • ffmpeg debian binaries. Latest versions from the debian repository for Debian Sarge works fine with Motion.
  • Certified ffmpeg CVS snapshot for latest Motion release is available from the Motion Sourceforge Related Projects file area

The timelapse feature always runs mpeg1 with both ffmpeg 0.4.8 and 0.4.9 and newer. Motion simply creates the timelapse film with a standard mpeg1 framerate. Note : maximum size for timelapse files is 2GB.

In principle Motion can be made to support many other formats. It requires additional coding in Motion. You are welcome to submit patches. All ffmpeg related code is in the source file ffmpeg.c. It is not trivial to do because the ffmpeg libraries not documented at all. All you have is a couple of code examples.

To build ffpmeg from source follow these steps:

Download the ffmpeg and untar it to /usr/local/ffmpeg. Then it should be a simple matter of entering the ffmpeg directory and run the commands 

cd /usr/local/ffmpeg
./configure --enable-shared
make
make install

This creates the libavcodec.so and libavformat.so libraries under /usr/local/lib and header files under /usr/local/include/ffmpeg.

You probably need to do one more step.

Make sure you have 'root' privileges for the next steps.

Open the file /etc/ld.so.conf in your favorite text editor.

Add this line of text if it is not already there - otherwise go to the next step (ldconfig).

/usr/local/lib Run the command ldconfig.

Motion should now be able to find the shared libraries for ffmpeg (libavcodec.so and libavformat.so) in /usr/local/lib.

You can also find a pre-compiled binary package (e.g. rpm or deb) and install this. Normally an rpm will place the libavcodec.so under /usr/lib. There are various RPMs available from different repositories. Some need additional RPMs that are actually not needed by Motion but need to be installed to satisfy dependencies. The editor has tried different RPMs of ffmpeg-0.4.8 and they all seem to work.

Motion then need to be built by running ./configure, make and make install. (Note that with earlier versions of motion you had to specify the location of libavcodec. Now configure searches for the shared library in /usr/lib and /usr/local/lib by default.)

Note that if you install ffmpeg from source and already have ffmpeg installed from an RPM, the Motion configure may very well find the binary library from the rpm instead of the sources. Make sure to uninstall any old ffmpeg RPMs before you install ffmpeg from sources.

These are the config file options related to ffmpeg.

ffmpeg_bps

  • Type: Integer
  • Range / Valid values: 0 - 9999999
  • Default: 400000
  • Option Topic

Bitrate of mpegs produced by ffmpeg. Bitrate is bits per second. Default: 400000 (400kbps). Higher value mans better quality and larger files. Option requires that ffmpeg libraries are installed.

To use this feature you need to install the FFmpeg Streaming Multimedia System.

Experiment to get the desired quality. The better quality the bigger files. This option is ignored if ffmpeg_variable_bitrate is not 0 (disabled).

ffmpeg_cap_motion

  • Type: Boolean
  • Range / Valid values: on, off
  • Default: off
  • Option Topic

Use ffmpeg libraries to encode motion type mpeg movies where you only see the pixels that changes.

Works like ffmpeg_cap_new but outputs motion pixel type pictures instead.

This feature generates the special motion type movie where you only see the pixels that changes as a graytone image. If labelling is enabled you see the largest area in blue. Smartmask is shown in red. The filename given is the same as the normal mpegs except they have an 'm' appended after the filename before the .mpg. E.g. 20040424181525m.mpg

To use this feature you need to install the FFmpeg Streaming Multimedia System

ffmpeg_cap_new

  • Type: Boolean
  • Range / Valid values: on, off
  • Default: off
  • Option Topic

Use ffmpeg libraries to encode mpeg movies in realtime.

Generates a new film at the beginning of each new event and appends to the film for each motion detected within the same event. The current event ends when the time defined by the 'gap' option has passed with no motion detected. At the next detection of motion a new mpeg film is started.

To use this feature you need to install the FFmpeg Streaming Multimedia System

Must not be included in config file without having ffmpeg installed.

ffmpeg_deinterlace

  • Type: Boolean
  • Range / Valid values: on, off
  • Default: off
  • Option Topic

Use ffmpeg to deinterlace video. Necessary if you use an analog camera and see horizontal combing on moving objects in video or pictures.

To use this feature you need to install the FFmpeg Streaming Multimedia System

Must not be included in config file without having ffmpeg installed.

ffmpeg_timelapse

  • Type: Boolean
  • Range / Valid values: 0 - 2147483647
  • Default: 0 (disabled)
  • Option Topic

Create a timelapse movie saving a picture frame at the interval in seconds set by this parameter. Set it to 0 if not used.

This feature uses ffmpegs libavcodec to encode a timelaps movie saving a picture frame at the interval in seconds set by this parameter. Setting this option to 0 disables it.

The feature gives your viewer the chance to watch the day pass by. It makes a nice effect to film flowers etc closeup during the day. Options like frame_rate, snapshot, gap etc have no impact on the ffmpeg timelapse function.

Note that the timelapse format is always mpeg1 independent of ffmpeg_video_codec. This is because mpeg1 allows the timelapse to stop and the file to be reopened and more film appended.

To use this feature you need to install the FFmpeg Streaming Multimedia System.

(renamed from ffmpeg_timelaps to ffmpeg_timelapse in 3.1.14)

ffmpeg_timelapse_mode

  • Type: Discrete Strings
  • Range / Valid values: hourly, daily, weekly-sunday, weekly-monday, monthly, manual
  • Default: daily
  • Option Topic

The file rollover mode of the timelapse video.

Note that it is important that you use the conversion specifiers in ffmpeg_filename that ensure that the new timelapse file indeed is a new file. If the filename does not change Motion will simply append the timelapse pictures to the existing file.

The value 'Manual' means that Motion does not automatically rollover to a new filename. You can do it manually using the http control interface by setting the option 'ffmpeg_timelapse' to 0 and then back to your chosen value. Value 'hourly' rolls over on the full hour. Value 'daily' which is the default rolls over at midnight. There are two weekly options because depending on where you come from a week may either start on Sunday or Monday. And 'monthly' naturally rolls over on the 1st of the month.

ffmpeg_variable_bitrate

  • Type: Integer
  • Range / Valid values: 0, 2 - 31
  • Default: 0 (disabled)
  • Option Topic

Enables and defines variable bitrate for the ffmpeg encoder. ffmpeg_bps is ignored if variable bitrate is enabled. Valid values: 0 (default) = fixed bitrate defined by ffmpeg_bps, or the range 2 - 31 where 2 means best quality and 31 is worst.

Experiment for the value that gives you the desired compromise between size and quality.

ffmpeg_video_codec

  • Type: Discrete Strings
  • Range / Valid values: mpeg1 (ffmpeg-0.4.8 only), mpeg4, msmpeg4, swf, flv, ffv1
  • Default: mpeg4
  • Option Topic

Codec to be used by ffmpeg for the video compression. Timelapse mpegs are always made in mpeg1 format independent from this option.

mpeg1 gives you files with extension .mpg. It is only supported by the old ffmpeg version 0.4.8. The ffmpeg team decided no longer to support non-standard framerates for mpeg1 from ffmpeg version 0.4.9pre1.

mpeg4 or msmpeg4 give you files with extension .avi

msmpeg4 is recommended for use with Windows Media Player because it requires with no installation of codec on the Windows client.

swf gives you a flash film with extension .swf

flv gives you a flash video with extension .flv

ffv1 , FF video codec 1 for Lossless Encoding ( experimental )

This option does not affect the timelapse feature. Timelapse is always recorded in mpeg1 format because we need to be able to append to an existing file. mpeg4 does not easily allow this.

See also the section Advanced Filenames where the two additional options ffmpeg_filename and timelapse_filename are defined.

If you want to use this feature you can read about the FFmpeg Streaming Multimedia System

Snapshots - The Traditional Periodic Web Camera

Motion can also act like a traditional web camera.

snapshot_interval

  • Type: Integer
  • Range / Valid values: 0 - 2147483647
  • Default: 0 (disabled)
  • Option Topic

Make automated snapshots every 'snapshot_interval' seconds.

The snapshots are stored in the target directory + the directory/filename specified by the snapshot_filename option.

This is the traditional web camera feature where a picture is taken at a regular interval independently of motion in the picture.

See the also snapshot_filename option in the section Advanced Filenames.

Text Features

Text features are highly flexible. You can taylor the text displayed on the images and films to your taste and you can add your own user defined text.

This is how the overlayed text is located.

  





 

 CHANGES





 



TEXT_LEFT

TEXT_RIGHT
YYYY-MM-DD
HH:MM:SS 

You are allowed to put the text in quotation marks. This allows you to use leading spaces. By combining spaces and new lines '\n' you can place your text anywhere on the picture. Experiment to find your preferred look. When setting the text using http remote control the text must be URL encoded. The browser does this for you. If you need to set it with a command line tool, use a browser first and let it make the encoded URL for you. Then you can copy paste it to your script file or cron line or whatever you want to use.

Below are the options that controls the display of text. The 'locate' option is not a text feature but described here because it is related to information overlayed on the output images.

The text_event feature is special in that it defines the conversion specifier %C which can be used both for text display and for filenames.

locate

  • Type: Boolean
  • Range / Valid values: on, off, preview
  • Default: off
  • Option Topic

Locate and draw a box around the moving object. Value 'preview' makes Motion only draw a box on a saved preview jpeg image and not on the saved mpeg movie.

The value 'preview' only works when 'output_normal' is set to either 'first' or 'best'.

text_changes

  • Type: Boolean
  • Range / Valid values: on, off
  • Default: off
  • Option Topic

Turns the text showing changed pixels on/off.

By setting this option to 'on' the number of pixels that changed compared to the reference frame is displayed in the upper right corner of the pictures. This is good for calibration and test. Maybe not so interesting for a greater public. Set it to your personal taste.

text_double

  • Type: Boolean
  • Range / Valid values: on, off
  • Default: off

Draw characters at twice normal size on images.

This option makes the text defined by text_left, text_right and text_changes twice the normal size. This may be useful when using large picture formats such as 640 x 480.

text_event

  • Type: String
  • Range / Valid values: Max 4095 characters
  • Default: %Y%m%d%H%M%S
  • Option Topic

This option defines the value of the speciel event conversion specifier %C. You can use any conversion specifier in this option except %C. Date and time values are from the timestamp of the first image in the current event.

The idea is that %C can be used filenames and text_left/right for creating a unique identifier for each event.

Option text_event defines the value %C which then can be used in filenames and text_right/text_left. The text_event/%C uses the time stamp for the first image detected in a new event. %C is an empty string when no event is in progress (gap period expired). Pre_captured and minimum_motion_frames images are time stamped before the event happens so %C in text_left/right does not have any effect on those images.

text_left

  • Type: String
  • Range / Valid values: Max 4095 characters
  • Default: Not defined
  • Option Topic

User defined text overlayed on each in the lower left corner. Use A-Z, a-z, 0-9, " / ( ) @ ~ # < > \ , . : - + _ \n and conversion specifiers (codes starting by a %).

text_left is displayed in the lower left corner of the pictures. If the option is not defined no text is displayed at this position.

You can place the text in quotation marks to allow leading spaces. With a combination is spaces and newlines you can position the text anywhere on the picture.

Detailed Description

A conversion specifier is a code that starts by % (except newline which is \n). The conversion specifiers used has the same function as for the C function strftime (3). The most commonly used are:

  • %Y = year
  • %m = month as two digits
  • %d = date
  • %H = hour
  • %M = minute
  • %S = second
  • %T = HH:MM:SS

These are unique to motion

  • %v = event
  • %q = frame number
  • %t = thread (camera) number
  • %D = changed pixels
  • %N = noise level
  • %i = width of motion area
  • %J = height of motion area
  • %K = X coordinate of motion center
  • %L = Y coordinate of motion center
  • %C = value defined by text_event

With a combination of text, spaces, new lines \n and conversion specifiers you have some very flexible text features.

For a full list of conversion specifiers see the section Conversion Specifiers for Advanced Filename and Text Feature.

text_right

  • Type: String
  • Range / Valid values: Max 4095 characters
  • Default: %Y-%m-%d\n%T
  • Option Topic

User defined text overlayed on each in the lower right corner. Use A-Z, a-z, 0-9, " / ( ) @ ~ # < > , . : - + _ \n and conversion specifiers (codes starting by a %). Default: %Y-%m-%d\n%T = date in ISO format and time in 24 hour clock

text_right is displayed in the lower right corner of the pictures. If the option is not defined no text is displayed at this position.

You can place the text in quotation marks to allow leading spaces. With a combination is spaces and newlines you can position the text anywhere on the picture.

A major difference from text_left is that if this option is undefined the default is %Y-%m-%d\n%T which displays the date in ISO format YYYY-MM-DD and below the time in 24 hour clock HH:MM:SS.

  • %L = Y coordinate of motion center
  • %C = value defined by text_event

With a combination of text, spaces, new lines \n and conversion specifiers you have some very flexible text features.

For a full list of conversion specifiers see the section Conversion Specifiers for Advanced Filename and Text Feature.

Advanced Filenames

Motion has a very advanced and flexible automated filenaming feature.

By using conversion specifiers (codes that consist of a '%' followed by a letter) you can build up the filenames including sub directories for pictures and movies using any combination of letters, numbers and conversion specifiers which are codes that represents time, date, event number and frame numbers.

The option target_dir is the target directory for all snapshots, motion images and normal images. The default is the current working directory (current working directory of the terminal from which motion was started). You will normally always want to specify this parameter.

Note that the options snapshot_filename, jpeg_filename, ffmpeg_filename, and timelapse_filename all allow specifying directories by using '/' in the filename. These will all be relative to target_dir. This means in principle that you can specify target_dir as '/' and be 100% flexible. It also means that Motion can write files all over your harddisk if you make a mistake. It is recommended to specify the target_dir as deep or detailed as possible for this reason. And note that targer_dir does not allow conversion specifiers.

The conversion specifier %C which is defined by the option text_event is interesting in connection with filenames because it can be used to create files and directories for each event in a very flexible way.

The convertion specifier %t (thread/camera number) is also very useful. Here is an example of filename definitions in motion.conf: 

target_dir /usr/local/webcam
snapshot_filename cam%t/%v-%Y%m%d%H%M%S-snapshot
jpeg_filename cam%t/%v-%Y%m%d%H%M%S-%q
ffmpeg_filename cam%t/%v-%Y%m%d%H%M%S
timelapse_filename cam%t/%Y%m%d%H-timelapse

The smart thing is that this defines the filename of all your camera threads in motion.conf so you do not need to specify target dir and filenames in the thread config files. In the above example an mpegfile for camera thread 3 will be saved as a filename similar to /usr/local/webcam/cam3/28-20051128130840.avi

NOTE: Unless you use the minimum_gap option to limit the number of shots to less then one per second - you must use the frame modifier %q as part of the jpeg_filename. Otherwise the pictures saved within the same second will overwrite each other. The %q in jpeg_filename ensures that each jpeg (or ppm) picture saved gets a unique filename.

ALERT! Security Warning! Note that the flexibility of this feature also means you have to pay attention to the following.

  • Anyone with access to the remote control port (http) can alter the values of these options and save files anywhere on your server with the same privileges as the user running Motion. Anyone can access your control port if you have not either limited access to localhost or limited access using firewalls in the server. You should always have a router between a machine running Motion with remote control enabled and the Internet and make sure the Motion control port is not accessible from the outside.
  • Anyone with local access to the computer and edit rights to the motion.conf file can alter the values of these options and save files anywhere on your server with the same privileges as the user running Motion. Make sure the motion.conf file is maximum readonly to anyone else but the user running Motion.
  • It is a good idea to run Motion as a harmless user. Not as root.

These are the advanced filename options in motion.conf

ffmpeg_filename (now called movie_filename)

ALERT! This option was renamed to movie_filename in 3.2.5 to enable better integration of alternative movie libraries to the current ffmpeg solution.

  • Type: String
  • Range / Valid values: Max 4095 characters
  • Default: %v-%Y%m%d%H%M%S
  • Option Topic

File path for motion triggered ffmpeg movies (mpeg) relative to target_dir. This option was renamed to movie_filename in 3.2.5 to enable better integration of alternative movie libraries to the current ffmpeg solution.

Default value is equivalent to legacy 'oldlayout' option For Motion 3.0 compatible mode (directories based on date and time) choose: %Y/%m/%d/%H%M%S

File extension .mpg or .avi is automatically added so do not include this.

This option uses conversion specifiers which are codes that start by % and then a letter. The conversion specifiers used has the same function as for the C function strftime (3). The most commonly used are:

  • %Y = year
  • %m = month as two digits
  • %d = date
  • %H = hour
  • %M = minute
  • %S = second
  • %T = HH:MM:SS

These are unique to motion

  • %v = event
  • %q = frame number
  • %t = thread (camera) number
  • %D = changed pixels
  • %N = noise level
  • %i = width of motion area
  • %J = height of motion area
  • %K = X coordinate of motion center
  • %L = Y coordinate of motion center
  • %C = value defined by text_event

If you are happy with the directory structures the way they were in earlier versions of motion use %v-%Y%m%d%H%M%S for 'oldlayout on' and %Y/%m/%d/%H%M%S for 'oldlayout off'.

jpeg_filename

  • Type: String
  • Range / Valid values: Max 4095 characters
  • Default: %v-%Y%m%d%H%M%S-%q
  • Option Topic

File path for motion triggered images (jpeg or ppm) relative to target_dir. Value 'preview' makes a jpeg filename with the same name body as the associated saved mpeg movie file.

Default value is equivalent to legacy 'oldlayout' option. For Motion 3.0 compatible mode (directories based on date and time) choose: %Y/%m/%d/%H/%M/%S-%q

This option uses conversion specifiers which are codes that start by % and then a letter. The conversion specifiers used has the same function as for the C function strftime (3). The most commonly used are:

  • %Y = year
  • %m = month as two digits
  • %d = date
  • %H = hour
  • %M = minute
  • %S = second
  • %T = HH:MM:SS

These are unique to motion

  • %v = event
  • %q = frame number
  • %t = thread (camera) number
  • %D = changed pixels
  • %N = noise level
  • %i = width of motion area
  • %J = height of motion area
  • %K = X coordinate of motion center
  • %L = Y coordinate of motion center
  • %C = value defined by text_event

If you are happy with the directory structures the way they were in earlier versions of motion use %v-%Y%m%d%H%M%S-%q for 'oldlayout on' and %Y/%m/%d/%H/%M/%S-%q for 'oldlayout off'.

The value 'preview' only works when 'output_normal' is set to 'best'. It makes Motion name the best preview jpeg file (image with most changed pixels during the event) with the same body name as the mpeg movie created during the same event. The purpose is to create a good single image that represents the saved mpeg moview so you can decide if you want to see it and spend time downloading it from a web page.

movie_filename

  • Type: String
  • Range / Valid values: Max 4095 characters
  • Default: %v-%Y%m%d%H%M%S
  • Option Topic

File path for motion triggered ffmpeg movies (mpeg) relative to target_dir. This was previously called ffmpeg_filename.

ALERT! This option was renamed from ffmpeg_filename to movie_filename in Motion 3.2.5.

Default value is equivalent to legacy 'oldlayout' option For Motion 3.0 compatible mode (directories based on date and time) choose: %Y/%m/%d/%H%M%S

File extension .mpg or .avi is automatically added so do not include this.

This option uses conversion specifiers which are codes that start by % and then a letter. The conversion specifiers used has the same function as for the C function strftime (3). The most commonly used are:

  • %Y = year
  • %m = month as two digits
  • %d = date
  • %H = hour
  • %M = minute
  • %S = second
  • %T = HH:MM:SS

These are unique to motion

  • %v = event
  • %q = frame number
  • %t = thread (camera) number
  • %D = changed pixels
  • %N = noise level
  • %i = width of motion area
  • %J = height of motion area
  • %K = X coordinate of motion center
  • %L = Y coordinate of motion center
  • %C = value defined by text_event

If you are happy with the directory structures the way they were in earlier versions of motion use %v-%Y%m%d%H%M%S for 'oldlayout on' and %Y/%m/%d/%H%M%S for 'oldlayout off'.

snapshot_filename

  • Type: String
  • Range / Valid values: Max 4095 characters
  • Default: %v-%Y%m%d%H%M%S-snapshot
  • Option Topic

File path for snapshots (jpeg or ppm) relative to target_dir.

Default value is equivalent to legacy 'oldlayout' option. For Motion 3.0 compatible mode (directories based on date and time) choose: %Y/%m/%d/%H/%M/%S-snapshot

File extension .jpg or .ppm is automatically added so do not include this A symbolic link called lastsnap.jpg (or lastsnap.ppm) created in the target_dir will always point to the latest snapshot, unless snapshot_filename is exactly 'lastsnap'

This option uses conversion specifiers which are codes that start by % and then a letter. The conversion specifiers used has the same function as for the C function strftime (3). The most commonly used are:

  • %Y = year
  • %m = month as two digits
  • %d = date
  • %H = hour
  • %M = minute
  • %S = second
  • %T = HH:MM:SS

If you are happy with the directory structures the way they were in earlier versions of motion use %v-%Y%m%d%H%M%S-snapshot for 'oldlayout on' and %Y/%m/%d/%H/%M/%S-snapshot for 'oldlayout off'.

For the equivalent of the now obsolete option 'snap_overwrite' use the value 'lastsnap'.

target_dir

  • Type: String
  • Range / Valid values: Max 4095 characters
  • Default: Not defined = current working directory
  • Option Topic

Target directory for picture and movie files.

This is the target directory for all snapshots, images files and movie files. The default is the current working directory (current working directory of the terminal from which motion was started). You will normally always want to specify this parameter as an absolute path.

Note that the options snapshot_filename, jpeg_filename, ffmpeg_filename, and timelapse_filename all allows specifying directories. These will all be relative to 'target_dir'. This means in principle that you can specify target_dir as '/' and be 100% flexible. It also means that Motion can write files all over your harddisk if you make a mistake. It is recommended to specify the target_dir as deep or detailed as possible for this reason.

timelapse_filename

  • Type: String
  • Range / Valid values: Max 4095 characters
  • Default: %v-%Y%m%d-timelapse
  • Option Topic

File path for timelapse mpegs relative to target_dir (ffmpeg only).

Default value is equivalent to legacy 'oldlayout' option.

For Motion 3.0 compatible mode (directories based on date and time) choose: %Y/%m/%d-timelapse

File extension .mpg is automatically added so do not include this.

This option uses conversion specifiers which are codes that start by % and then a letter. The conversion specifiers used has the same function as for the C function strftime (3). The most commonly used are:

  • %Y = year
  • %m = month as two digits
  • %d = date

  • %i = width of motion area
  • %J = height of motion area
  • %K = X coordinate of motion center
  • %L = Y coordinate of motion center
  • %C = value defined by text_event

If you are happy with the directory structures the way they were in earlier versions of motion use %v-%Y%m%d-timelapse for 'oldlayout on' and %Y/%m/%d-timelapse for 'oldlayout off'.

Conversion Specifiers for Advanced Filename and Text Features

The table below shows all the supported Conversion Specifiers you can use in the options text_event, text_left, text_right, sql_query, snapshot_filename, jpeg_filename, ffmpeg_filename, timelapse_filename, on_event_start, on_event_end, on_picture_save, on_movie_start, on_movie_end, and on_motion_detected.

Webcam Server

Motion has simple webcam server built in. The video stream is in mjpeg format.

Each thread can have its own webcam server. If you enable the webcam server (option webcam_port to a number different from 0) and you have more than one camera, you must make sure to include webcam_port in each thread config file and set webcam_port to different and unique port numbers or zero (disable). Otherwise each webcam server will use the setting from the motion.conf file and try to bind to the same port. If the webcam_port numbers are not different from each other Motion will disable the webcam feature.

Note: The webcam server feature requires that the option ppm is set to off. (I.e. saved images are jpeg images).

The webcam_maxrate and webcam_quality options are important to limit the load on your server and link. Don't set them too high unless you only use it on the localhost or on an internal LAN. The option webcam_quality is equivalent to the quality level for jpeg pictures.

The webcam_limit option prevents people from loading your Network connection by streaming for hours and hours. The options defines the number of picture frames sent as mjpeg Motion will allow without re-connecting (e.g. clicking refresh in the browser).

The option webcam_localhost is a security feature. When enabled you can only access the webserver on the same machine as Motion is running on. If you want to present a live webcam on your web site this feature must be disabled.

The webserver generates a stream in "multipart jpeg" format (mjpeg). You cannot watch the stream with most browsers. Only certain versions of Netscape works. Mozilla and Firefox brosers can view the mjpeg stream but you often have to refresh the page once to get the streaming going. Internet Explorer cannot show the mjpeg stream. For public viewing this is not very useful. There exists a java applet called Cambozola which enabled any Java capable browser to show the stream. To enable the feature to a broad audience you should use this applet or similar.

To use the webcam feature with Cambozola is actually very simple.

1. Create a html page in which you will want the streamed picture.

2. In the html page include this code 

<applet code=com.charliemouse.cambozola.Viewer
    archive=cambozola.jar width="320" height="240" style="border-width:1; border-color:gray; border-style:solid;">
    <param name=url value="http://www.myurl.com:8081">
</applet>

Where the width and height is the image size of the video stream.

Replace www.myurl.com:8081 by the real url and port number of your choice.

3. In the same directory you place the cambozola.jar file. No need to build the java applet from source. Simply use the applet in the package.

4. Enable the feature in motion.conf.

You can also view the live webcam stream using MPlayer like this: 

mplayer -demuxer lavf http://www.myurl.com:8081/stream.mjpg

Note that the stream.mjpg part is important, without it you will get a LAVF_check: no clue about this gibberish! error from libavformat.

These are the special webcam parameters.

webcam_limit

  • Type: Integer
  • Range / Valid values: 0 - 2147483647
  • Default: 0 (unlimited)
  • Option Topic

Limit the number of frames to number frames. After 'webcam_limit' number of frames the connection will be closed by motion. The value 0 means unlimited.

Number can be defined by multiplying actual webcam rate by desired number of seconds. Actual webcam rate is the smallest of the numbers framerate and webcam_maxrate.

webcam_localhost

  • Type: Boolean
  • Range / Valid values: on, off
  • Default: on
  • Option Topic

Limits the access to the webcam to the localhost.

By setting this to on, the webcam can only be accessed on the same machine on which Motion is running.

webcam_maxrate

  • Type: Integer
  • Range / Valid values: 1 - 100
  • Default: 1
  • Option Topic

Limit the framerate of the webcam in frames per second. Default is 1. Set the value to 100 for practically unlimited.

Don't set 'webcam_maxrate' too high unless you only use it on the localhost or on an internal LAN.

webcam_motion

  • Type: Boolean
  • Range / Valid values: on, off
  • Default: off
  • Option Topic

If set to 'on' Motion sends slows down the webcam stream to 1 picture per second when no motion is detected. When motion is detected the stream runs as defined by webcam_maxrate. When 'off' the webcam stream always runs as defined by webcam_maxrate.

Use this option to save bandwidth when there is not anything important to see from the camera anyway.

Note that this feature was greatly improved from Motion version 3.2.2. Before 3.2.2 the option stopped the webcam stream except when Motion was detected. This made the feature not very useful because it made it difficult to connect to the webcam stream and most mjpeg viewers would timeout and give an error message. From 3.2.2 the feature has been greatly improved and actually quite recommendable.

webcam_port

  • Type: Integer
  • Range / Valid values: 0 - 65535
  • Default: 0 (disabled)
  • Option Topic

TCP port on which motion will listen for incoming connects with its webcam server.

Note that each camera thread must have its own unique port number and it must also be different from the control_port number.

A good value to select is 8081 for camera 1, 8082 for camera 2, 8083 for camera 3 etc etc.

webcam_quality

  • Type: Integer
  • Range / Valid values: 1 - 100
  • Default: 50
  • Option Topic

Quality setting in percent for the mjpeg picture frames transferred over the webcam connection. Keep it low to restrict needed bandwidth.

The mjpeg stream consists of a header followed by jpeg frames separated by content-length and boundary string. The quality level defines the size of the individual jpeg pictures in the mjpeg stream. If you set it too high you need quite a high bandwidth to view the stream.

Remote Control with http

Motion can be remote controlled via a simple http interface. http is the language a normal web browser talks when it requests a web page. The web server answers back with some simple http headers followed by a webpage coded in HTML.

Most Motion config options can be changed while Motion is running except options related to the size of the captured images and mask files which are loaded only when Motion starts. So only your fantasy sets the limit to what you can change combining cron and the remote control interface for Motion.

So the most obvious tool to use to remote control Motion is any web browser. All commands are sent using the http GET method which simply means that the information is sent via the URL and maybe a query string. You can use any browser (Firefox, Mozilla, Internet Explorer, Konquerer, Opera etc). You can also use the text based browser lynx to control Motion from a console. It navigates fine through the very simple and minimalistic http control interface of Motion.

The details about how to control Motion via the URL is described in detail in the Motion http API topic.

But it is probably simpler to connect to the control port with a browser, navigate to the function you want, and copy the URL from the browser URL entry line. If your control_port is 8080 and you browse from the same machine on which Motion runs simply look up http://localhost:8080/ and navigate around. Connecting from a remote machine is done by using a domain name (example http://mydomain.com:8080/) or the IP address of the machine (example http://192.168.1.4:8080/). The option control_localhost must be off to allow connection from a remote machine.

If you want to use a script or cron to automatically change Motion settings while Motion runs you use a program that can fetch a webpage. We simply just throw away the html page that Motion returns. Programs commonly available on Linux machines are wget and lwp-request. Here is an example of how to start and stop motion detection via cron. These two lines are added to /etc/crontab. 

0 9 * * * root /usr/bin/lwp-request http://localhost:8080/0/detection/start > /dev/null
0 18 * * * root /usr/bin/lwp-request http://localhost:8080/0/detection/pause > /dev/null

If you want to use the http remote control from your own software (for example your own PHP front end) you can set the new motion.conf option html_output off. Then Motion answers back with very basic text only and no html around it. A bit like the xmlrpc interface did.

To remote control Motion from a web pages you can for example use PHP. In PHP it takes this simple code line to send a remote commend to Motion. Here we pause motion detection for camera 2

readfile('http://localhost:8080/2/detection/pause');

What happened to XMLRPC?

XMLRPC is replaced by a simpler http remote control interface. It is still being worked on but it is absolutely useable now and much nicer to work with than xmlrpc. Another advantage is that you do not need to install xmlrpc libraries. It is all written in standard C.

ALERT! Security Warning! Note that this feature also means you have to pay attention to the following.

  • Anyone with access to the remote control port (http) can alter the values of any options and save files anywhere on your server with the same privileges as the user running Motion. They can execute any command on your computer with the same privileges as the user running Motion. Anyone can access your control port if you have not either limited access to localhost or limited access using firewalls in the server. You should always have a router between a machine running Motion with remote control enabled and the Internet and make sure the Motion control port is not accessible from the outside.
  • If you limit control port to localhost you still need to take care of any user logging into the server with any kind of terminal session.
  • It is a good idea to run Motion as a harmless user. Not as root!!

These are the config file options that control Motion.

These must be placed in motion.conf and not in a thread config file.

control_authentication

  • Type: String
  • Range / Valid values: Max 4096 characters
  • Default: Not defined
  • Option Topic

To protect HTTP Control by username and password, use this option for HTTP 1.1 Basic authentication. The string is specified as username:password. Do not specify this option for no authentication. This option must be placed in motion.conf and not in a thread config file.

By setting this to on, the control using http (browser) can only be accessed using login and password ( following the Basic Authentication defined in HTTP RFC).

control_html_output

  • Type: Boolean
  • Range / Valid values: on, off
  • Default: on
  • Option Topic

Enable HTML in the answer sent back to a browser connecting to the control_port. This option must be placed in motion.conf and not in a thread config file.

The recommended value for most is "on" which means that you can navigate and control Motion with a normal browser. By setting this option to "off" the replies are in plain text which may be easier to parse for 3rd party programs that control Motion.

control_localhost

  • Type: Boolean
  • Range / Valid values: on, off
  • Default: on
  • Option Topic

Limits the http (html) control to the localhost. This option must be placed in motion.conf and not in a thread config file.

By setting this to on, the control using http (browser) can only be accessed on the same machine on which Motion is running.

control_port

  • Type: Integer
  • Range / Valid values: 0 - 65535
  • Default: 0 (disabled)
  • Option Topic

Sets the port number for the http (html using browser) based remote control. This option must be placed in motion.conf and not in a thread config file.

This sets the TCP/IP port number to be used for control of motion using http (browser). Port numbers below 1024 normally requires that you have root privileges. Port 8080 is a fine choice of port to use for the purpose.

External Commands

Motion can execute external commands based on the motion detection and related events. They are all described in this section. The option quiet is also included in this section.

A redesign of the external commands was due. They were not very easy to understand, not all were flexible enough and some were missing. So a new external command feature set was made for 3.2.1 and on.

This is how the new script commands look like:

Function Old Option New Option Argument Appended
Start of event (first motion) execute on_event_start None
End of event (no motion for gap seconds) New! on_event_end None
Picture saved (jpg or ppm) onsave on_picture_save Filename of picture
Movie starts (mpeg file opened) onmpeg on_movie_start Filename of movie
Movie ends (mpeg file closed) onffmpegclose on_movie_end Filename of movie
Motion detected (each single frame with Motion detected) New! on_motion_detected None

Mail and sms has been removed because they were not configurable. If you want to send event-based mails or sms, just use one of those commands above and send the mail from that script. See What happened to mail and sms?

ALERT! Security Warning! Note that this feature also means you have to pay attention to the following.

  • Anyone with access to the remote control port (http) can execute any command on your computer with the same privileges as the user running Motion. Anyone can access your control port if you have not either limited access to localhost or limited access using firewalls in the server. You should always have a router between a machine running Motion with remote control enabled and the Internet and make sure the Motion control port is not accessible from the outside.
  • If you limit control port to localhost you still need to take care of any user logging into the server with any kind of GUI or terminal session. All it takes is a browser or single command line execution to change settings in Motion.
  • It is a good idea to run Motion as a harmless user. Not as root!!

These are the options

on_event_end

  • Type: String
  • Range / Valid values: Max 4095 characters
  • Default: Not defined
  • Option Topic

Command to be executed when an event ends after a period of no motion. The period of no motion is defined by option gap. You can use Conversion Specifiers and spaces as part of the command.

Full path name of the program/script.

This can be any type of program or script. Remember to set the execution bit in the ACL and if it is a script type program such as perl or bash also remember the shebang line (e.g. #!/user/bin/perl) as the first line of the script.

The command is run when an event is over. I.e. the number of seconds defined by the time 'gap' has passed since the last detection of motion and motion closes the mpeg file.

on_event_start

  • Type: String
  • Range / Valid values: Max 4095 characters
  • Default: Not defined
  • Option Topic

Command to be executed when an event starts. An event starts at first motion detected after a period of no motion defined by gap. You can use ConversionSpecifiers and spaces as part of the command.

Full path name of the program/script.

This can be any type of program or script. Remember to set the execution bit in the ACL and if it is a script type program such as perl or bash also remember the shebang line (e.g. #!/user/bin/perl) as the first line of the script.

The command is run when an event starts. I.e. the first motion is detected since the last event.

This option replaces the former options 'mail', 'sms' and 'execute'.

on_motion_detected

  • Type: String
  • Range / Valid values: Max 4095 characters
  • Default: Not defined
  • Option Topic

Command to be executed when a motion frame is detected. You can use Conversion Specifiers and spaces as part of the command.

Do not write "none" if you do not want to execute commands. Simply do not include the option in the file or comment it out by placing a "#" or ";" as the first character on the line before the execute command.

on_movie_end

  • Type: String
  • Range / Valid values: Max 4095 characters
  • Default: Not defined
  • Option Topic

Command to be executed when an ffmpeg movie is closed at the end of an event. You can use Conversion Specifiers and spaces as part of the command. Use %f for passing filename (with full path) to the command.

Full path name of the program/script.

This can be any type of program or script. Remember to set the execution bit in the ACL and if it is a script type program such as perl or bash also remember the shebang line (e.g. #!/user/bin/perl) as the first line of the script.

The command is run when an event is over. I.e. the number of seconds defined by the time 'gap' has passed since the last detection of motion and motion closes the mpeg file.

This option was previously called onffmpegclose.

Note that from Motion 3.2.4 the path name of the picture file is no longer appended to the command. Instead you can use the conversion specifier %f to insert the picture filename (full path) anywhere in the command.

Most common conversion specifiers

  • %Y = year, %m = month, %d = date
  • %H = hour, %M = minute, %S = second
  • %v = event
  • %q = frame number
  • %t = thread (camera) number
  • %D = changed pixels
  • %N = noise level
  • %i and %J = width and height of motion area
  • %K and %L = X and Y coordinates of motion center
  • %C = value defined by text_event
  • %f = filename with full path
  • %n = number indicating filetype

on_movie_start

  • Type: String
  • Range / Valid values: Max 4095 characters
  • Default: Not defined
  • Option Topic

Command to be executed when an mpeg movie is created. You can use Conversion Specifiers and spaces as part of the command. Use %f for passing filename (with full path) to the command.

Full path name of the program/script.

This can be any type of program or script. Remember to set the execution bit in the ACL and if it is a script type program such as perl or bash also remember the shebang line (e.g. #!/user/bin/perl) as the first line of the script. When you use ffmpeg the film is generated on the fly and on_movie_start then runs when the new mpeg file is created. Often you will want to use the on_movie_end option which runs when the mpeg file is closed and the event is over.

This option was previously called onmpeg.

Note that from Motion 3.2.4 the path name of the picture file is no longer appended to the command. Instead you can use the conversion specifier %f to insert the picture filename (full path) anywhere in the command.

Most common conversion specifiers

  • %Y = year, %m = month, %d = date
  • %H = hour, %M = minute, %S = second

  • %N = noise level
  • %i and %J = width and height of motion area
  • %K and %L = X and Y coordinates of motion center
  • %C = value defined by text_event
  • %f = filename with full path
  • %n = number indicating filetype

on_picture_save

  • Type: String
  • Range / Valid values: Max 4095 characters
  • Default: Not defined
  • Option Topic

Command to be executed when an image is saved. You can use Conversion Specifiers and spaces as part of the command. Use %f for passing filename (with full path) to the command.

Full path name of the program/script.

This can be any type of program or script. Remember to set the execution bit in the file access control list (chmod) and if it is a script type program such as perl or bash also remember the shebang line (e.g. #!/usr/bin/perl) as the first line of the script.

Note that from Motion 3.2.4 the path name of the picture file is no longer appended to the command. Instead you can use the conversion specifier %f to insert the picture filename (full path) anywhere in the command.

  • %K and %L = X and Y coordinates of motion center
  • %C = value defined by text_event
  • %f = filename with full path
  • %n = number indicating filetype

quiet

  • Type: Boolean
  • Range / Valid values: on, off
  • Default: off
  • Option Topic

Be quiet, don't output beeps when detecting motion.

Only works in non-daemon mode.

What happened to mail and sms?

The 6 new on_xxxxx options replace the former execute, mail and sms options.

They are quite generic and flexible. These small bash scripts gives to the same functionality as mail and sms BUT you have all the flexibility you want to extend the messages, change the 'from' email address etc.

Sending email at start of event

Script written by JoergWeber 
#!/bin/sh

# Motion sample script to send an e-mail at start of an event.
# Replaces the former 'mail' option.
# Just define this script as 'on_event_start'-script in motion.conf like that:
# on_event_start send_mail "%Y-%m-%d %T"

#change to suit your needs:
#location of 'mail' binary
MAIL="/usr/bin/mail"
#Destination e-mail address
TO="root@localhost"
#Subject of the e-mail
SUBJECT="Motion detected"

#Don't change anything below this line

Tracking Control

This is still at the experimental stage. Read more about it motion tracking page.

Tracking Feature with Logitech Quickcam Sphere/Orbit

Motion supports controlling the pan and tilt feature of a Logitech Quickcam Sphere/Orbit.

Motion can move the camera to a fixed position given in degrees pan (left-right) and tilt (down-up). Movement can be set with absolute coordinates or relative to current position. There is also an auto tracking feature for the Logitech Quickcam Sphere/Orbit but it is not very mature. It is fun to play with but not very useful yet. See this topic of how KennethLavrsen controls his Sphere: LogitechSphereControl.

For a detailed description of http remote control see the section Remote Control with http.

Motion has special tracking options which use either a serial stepper motor controller, an iomojo smile cam or a Philips WebCam driver compatible pan/tilt camera such as the Logitech Quickcam Sphere or Orbit.

To disable tracking, set this to 0 and the other track options are ignored.

Value 1 is for the special Motion Tracking project using a stepper motor and a home made controller.

Value 2 is for the iomojo smilecam

Value 3 is for pwc type USB tracking cameras such as the Logitech Quickcam Sphere/Orbit which is driven by the pwc (Philips WebCam) driver. To use this camera your version of pwc must be at least 8.12.

Value 4 is the generic track type. Currently it has no other function than enabling some of the internal Motion features related to tracking. Eventually more functionality will be implemented for this type.

Value 5 is for uvcvideo type USB tracking cameras such as the Logitech Quickcam Sphere/Orbit MP (new Model) which is driven by the uvcvideo driver. This option was added in Motion 3.2.8.

Using Databases

Motion can be compiled with both MySQL and PostgreSQL database support. When enabled Motion adds a record to a table in the database as specified by the sql_query. The query contains the fields that are used and the value are given by using conversion specifiers for dynamic data like filename, time, number of detected pixels etc. Motion does not place any binary images in the database and it cannot remove old records.

Motion only adds records to the database when files are created. The database contains records of saved files which means to get a record in the database the feature that enables for example motion detection, timelapse, snapshots etc must be enabled. The sql_log options defines which types of files are logged in the database.

The following sql_log options are common to both MySQL and PostgreSQL.

sql_log_image

  • Type: Boolean
  • Range / Valid values: on, off
  • Default: on
  • Option Topic

Log to the database when creating motion triggered image file.

Configuration option common to MySQL and PostgreSQL. Motion must be built with MySQL or PostgreSQL support to use this feature.

sql_log_mpeg

  • Type: Boolean
  • Range / Valid values: on, off
  • Default: off
  • Option Topic

Log to the database when creating motion triggered mpeg file.

Configuration option common to MySQL and PostgreSQL. Motion must be built with MySQL or PostgreSQL support to use this feature.

sql_log_snapshot

  • Type: Boolean
  • Range / Valid values: on, off
  • Default: on
  • Option Topic

Log to the database when creating a snapshot image file.

Configuration option common to MySQL and PostgreSQL. Motion must be built with MySQL or PostgreSQL support to use this feature.

sql_log_timelapse

  • Type: Boolean
  • Range / Valid values: on, off
  • Default: off
  • Option Topic

Log to the database when creating timelapse mpeg file

Configuration option common to MySQL and PostgreSQL. Motion must be built with MySQL or PostgreSQL support to use this feature.

sql_query

  • Type: String
  • Range / Valid values: Max 4095 characters
  • Default: insert into security(camera, filename, frame, file_type, time_stamp, text_event) values('%t', '%f', '%q', '%n', '%Y-%m-%d %T', '%C')
  • Option Topic

SQL query string that is sent to the database. The values for each field are given by using convertion specifiers

Most common conversion specifiers

  • %Y = year, %m = month, %d = date
  • %H = hour, %M = minute, %S = second
  • %v = event
  • %q = frame number
  • %t = thread (camera) number
  • %D = changed pixels
  • %N = noise level
  • %i and %J = width and height of motion area
  • %K and %L = X and Y coordinates of motion center
  • %C = value defined by text_event
  • %f = filename with full path
  • %n = number indicating filetype

See the "MySQL" section for detailed information about the database itself.

MySQL

You can use the MySQL database to register each file that is stored by motion.

You need to generate a new database with a name of your own choice. You must enter this name in the config file (mysql_db option). The default value for the option sql_query requires that you create a new database in MySQL with a new table called "security" with the following fields:

insert into security(camera, filename, frame, file_type, time_stamp, text_event) values('%t', '%f', '%q', '%n', '%Y-%m-%d %T', '%C')

  • camera (int) - camera (thread) number
  • filename (char60) - filename (full path)
  • frame (int) - the number of the picture frame
  • file_type (int) - file type as a number - see table below.
  • time_stamp (timestamp) - timestamp for the picture in native database format
  • text_event (timestamp) - The text from the text_event option which by default is compatible with timestamps in SQL.

Note from version 3.2.4 the introduction of sql_query completely redefines the way you setup the SQL feature. It is now 100% flexible and can easily be made compatible with your existing Motion database from earlier versions of Motion.

These are the file type descriptions and the file type numbers stored in the database.

Normal image 1
Snapshot image 2
Motion image (showing only pixels defined as motion) 4
Normal mpeg image 8
Motion mpeg (showing only pixels defined as motion) 16
Timelapse mpeg 32

You can create the table using the following SQL statement.

CREATE TABLE security (camera int, filename char(80) not null, frame int, file_type int, time_stamp timestamp(14), text_event timestamp(14));

If you choose to use text_event for a non-timestamp value you can instead define something like.

CREATE TABLE security (camera int, filename char(80) not null, frame int, file_type int, time_stamp timestamp(14), text_event char(40));

Remember to update grant table to give access to the mysql username you choose for motion.

It would be too much to go into detail about how to setup and use MySQL. After all this is a guide about Motion. However here are some hints and links.

Video4Linux Loopback Device

You can use this driver for looking at motion in realtime. The video4linux driver is written by the same author that first created Motion. You can find the source and a brief description at the video4linux loopback device web page.

The video4linux device is a Kernel module which installs itself as a video pipe. It has an input and an output. The module simply takes anything that comes on its input and send it out at the output. The purpose of this is to create a standard video4linux type video device that other programs can then use. You may now ask: "What do I need that for?".

Only one program can access a video device at a time. When motion is using a camera - no other program can access the same camera. But motion is made to be able to feed a video signal to the video loopback device. This way an additional program such as Camstream, Xawtv, a video stream server etc can watch the signal from a camera that motion uses already. What you see is not the live camera stream but the exact same picture that motion uses for detecting motion and the same pictures that are saved/streamed. You can also choose to see the "motion" type images where you see the pixels that are changing - live. Originally the video4linux pipe was used as an interface between Motion and a Webcam server. Since version 2.9 Motion has had its own webserver so this usage is no longer very relevant.

When you install the video loopback device it will create an input - for example /dev/video5 and an output - for example /dev/video6. You can then tell motion to "pipe" the video signal to the /dev/video5 and look at the pictures live using e.g. Camstream on /dev/video6. Camstream is "fooled" to think it is looking at a real camera.

Installing

Installing the video loopback device is not difficult. At least not when you have this document available.

First you must prepare your system for more video devices. You will need two extra devices for each video pipe that you want.

For example if you have 4 cameras they will probably run at /dev/video0, /dev/video1, /dev/video2, and /dev/video3. So you will need additional 8 video devices. This is easy to do. 

mknod /dev/video4 c 81 4
mknod /dev/video5 c 81 5
mknod /dev/video6 c 81 6
mknod /dev/video7 c 81 7
mknod /dev/video8 c 81 8
mknod /dev/video9 c 81 9
mknod /dev/video10 c 81 10
mknod /dev/video11 c 81 11

Note that the video device number is the same as the last parameter given on each line.

You may need to set the ownership and permissions (chown and chmod) to be the same as the video devices that were already there.

Now you need to install the video loopback device.

Download the latest video4linux loopback device . Place the file in a place of your own choice.

Untar and uncompress the file to the place you want the program installed. Editor recommends /usr/local/vloopback.

cd /usr/local

tar -xvzf /path/to/vloopback-1.1-rc1.tar.gz

You now have a directory called vloopback-1.1-rc1. You can rename it to vloopback (mv vloopback-1.1-rc1 vloopback). I recommend creating a symbolic link to the current version. This way you can more easily experiment with different versions simply by changing the link.

ln -s vloopback-1.1-rc1 vloopback

Now change to the new directory

cd vloopback

Build the code

make

There is a good chance that the make will not work and give you a long list of errors. To run make the following must be available on you machine.

  • The kernel source files must be installed.
  • The source files must be available at /usr/src/linux.
    E.g. the new Red Hat 7.3 does not have a link to the sources called linux. Instead there is a link called linux-2.4. This is easy to fix. Just create a link to the real source tree. Do not rename! Add a link using this command (replacing the kernel version number with the one you have on your machine)
    ln -s /usr/src/linux-2.4.18-4 /usr/src/linux
  • Alternatively you can change the vloopback makefile so that the "LINUXSRC=/usr/src/linux" line is changed to the actual path. I recommend the link solution since this may solve other similar problems that you can get when installing other software.

When compiling on a newer Linux distribution you may get a warning about a header file malloc.h. To remove this warning simply change the header reference as suggested by the warning.

In vloopback.c you replace the line

#include <linux/malloc.h>

with the line

#include <linux/slab.h>

Install the code you built as a Kernel module. There are two options: pipes should be set to the number of video loopbacks that you want. Probably one for each camera. The dev_offset defines which video device number will be the first. If dev_offset is not defined the vloopback module will install itself from the first available video device. If you want the cameras to be assigned to the lower video device numbers you must either load vloopback after loading the video device modules OR use the dev_offset option when loading vloopback. Vloopback then installs itself in the sequence input 0, output 0, input 1, output 1, input 2, output 2 etc. Here is shown the command for our example of 4 cameras and 4 loopback devices and the first loopback device offset to /dev/video4.

/sbin/insmod /usr/local/vloopback/vloopback.o pipes=4 dev_offset=4

When you run the command you may get a warning about tainting the Kernel. Just ignore this. You can choose to copy the vloopback.o file into a directory in the /lib/modules tree where the insmod/modprobe programs are already looking for modules. Then the command gets simpler (/sbin/insmod vloopback pipes=.....).

If you want the loopback device to load during boot, you can place the call in one of the bootup scripts such as /etc/rc.d/rc.local. Vloopback should be loaded before you start motion.

To activate the vloopback device in motion set the 'video_pipe' option in the motion.conf file. You can also view the special motion pictures where you see the changed pixels by setting the option 'motion_video_pipe' in motion.conf. When setting the video_pipe and/or motion_video_pipe options either specify the input device as e.g. /dev/video4. You can also set the parameter to '-' which means that motion will find the first vacant video loopback device input. If you have more than one camera you may want to control which loopback device each thread uses. Then you need to define the specific device name in motion.conf for the first camera and in each thread config file for the other cameras. If you set the video_pipe parameter to '-' in the motion.conf file and not setting it in the thread config files, motion automatically assign video devices in the same sequence as the threads are loaded. You can combine both video_pipe and motion_video_pipe but then naturally you will need twice as many pipes.

De-activating should be done with this command

/sbin/modprobe -r vloopback

Description of the motion.conf options related to video loopback device.

motion_video_pipe

  • Type: String
  • Range / Valid values: Max 4095 characters
  • Default: Not defined
  • Option Topic

The video4linux video loopback input device for motion images. If a particular pipe is to be used then use the device filename of this pipe, if a dash '-' is given motion will use /proc/video/vloopback/vloopbacks to locate a free pipe. Default: not set

Using this you can view the results in real time. E.g. by using the program camstream. The difference between this option and the video-pipe option is that this option shows the motion version of the images instead of the normal images.

Disable this option by not having it in the config file (or comment it out with "#" or ";").

video_pipe

  • Type: String
  • Range / Valid values: Max 4095 characters
  • Default: Not defined
  • Option Topic

The video4linux video loopback input device for normal images. If a particular pipe is to be used then use the device filename of this pipe. If a dash '-' is given motion will use /proc/video/vloopback/vloopbacks to locate a free pipe.

Using this you can view the results in real time. E.g. by using the program camstream.

Disable this option by not having it in the config file (or comment it out with "#" or ";").
