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 Lesser 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 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) 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., 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 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) year 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 Lesser General Public License instead of this License. vdr-plugin-streamdev/CONTRIBUTORS0000644000175000017500000001742713276341255016364 0ustar tobiastobiasSpecial thanks go to the following persons (if you think your name is missing here, please send an email to vdrdev@schmirler.de): Klaus Schmidinger for VDR as a whole for permission to use VDR 1.6.0 cRemux code for PES remuxing Sascha Volkenandt, the original author, for this great plugin The Metzler Brothers as a lot of code has been taken from their libdvbmpeg package Angelus (DOm) for providing Italian language texts for reporting problems with the Elchi-Patch Michal for sending a patch to select the HTTP streamtype via remote Rolf Ahrenberg for providing Finnish language texts for adding externremux.sh commandline parameter for silencing compiler warnings for adding PAT, PMT, PCR and EIT to HTTP TS streams for fixing a memory leak in buffer overflow situations for adding a return code check to vasprintf() for suggesting a fix of the Makefile's default target for a TS PAT repacker based on Petri Laine's VDR TS recording patch for making it possible to pass parameters to externremux.sh for removing pre VDR 1.4 legacy code for adding gettext support for fixing output format of some debug messages for replacing private members by cThread::Running()/Active() for improving externremux script termination for fixing PAT repacker version field for improving LIMIKUUTIO and PARENTALRATING patch detection for suggesting to include the charset in HTTP replies for requesting replacement of asprintf calls for suggesting to change the URL path from EXTERN to EXT for suggesting increased thread priorities for cStreamdevWriter/Streamer for adding "Hide mainmenu entry" option for polishing po file headers for adding the special meaning "show current channel" to channel 0 Rantanen Teemu for providing vdr-incompletesections.diff Thomas Keil for providing vdr-localchannelprovide.diff for maintaining the plugin for a while Artur Skawina for fixing an fd leak Norad for reporting a problem terminated externremux.sh children Udo Richter for fixing streamdev-server shutdown for speeding up cPluginStreamdevServer::Active() for adapting to VDR 1.5.0 API for adapting to VDR 1.7.1 for proper tsplay-0.2 patch detection greenman for reporting that the log could get flooded on connection failures.

Description: --------------- This PlugIn is a VDR implementation of the VTP (Video Transfer Protocol) Version 0.0.3 (see file PROTOCOL) and a basic HTTP Streaming Protocol. It consists of a server and a client part, but both parts are compiled together with the PlugIn source, but appear as separate PlugIns to VDR. The client part acts as a full Input Device, so it can be used in conjunction with a DXR3-Card, XINE, SoftDevice or others to act as a working VDR installation without any DVB-Hardware including EPG-Handling. The server part acts as a Receiver-Device and works transparently in the background within your running VDR. It can serve multiple clients and it can distribute multiple input streams (i.e. from multiple DVB-cards) to multiple clients using the native VTP protocol (for VDR-clients), or using the HTTP protocol supporting clients such as XINE, MPlayer and so on. With XMMS or WinAMP, you can also listen to radio channels over a HTTP connection. It is possible to attach as many clients as the bus and network can handle, as long as there is a device which can receive a specific channel. Multiple channels homed on the same transponder (which is determined by it's frequency) can be broadcasted with a single device. Additional clients can be programmed using the Protocol Instructions inside the PROTOCOL file. 2. Installation: ---------------- Let's say streamdev's version is 0.5.0 and vdr's version is 1.X.X. If you use anything else please exchange the version numbers appropriately (this way I don't have to update this section all the times;) ). After compiling the PlugIn as stated below, start either (or both) parts of it by specifying "-P streamdev-client" and/or "-P streamdev-server" on the VDR command line. What's important is that the client requests a channel using its Unique Channel ID. So, in order to find the channel at the server, it must have the same ID that is used on the client. You can achieve this by putting the server's channels.conf on the client, preferably after scanning. If you want to drive additional Input-Devices (with different sources) on the client, you can merge the channels.conf files. VDR will detect if the local device or the network device can receive the channels. Last, but not least you have to copy the streamdev-server folder into the "plugins/streamdev-server" subfolder of VDR's config-directory (which is equal to your video-directory if not specified otherwise). For example, if you didn't specify a separate config-directory, and set your video directory to "/video0", the directory has to be copied to /video0/plugins/streamdev-server. The directory contains a file named streamdevhosts.conf which you must adjust to your needs. The syntax is the same as for svdrphosts.conf, so please consult VDR's documentation on how to fill that file, if you can't do it on-the-fly. There's also a sample externremux.sh script in this directory. It is used by streamdev's external remux feature. The sample script uses mencoder by default. Please check the script for further information. You can specify a different script location with the -r parameter. The VDR commandline would then include a "-P 'streamdev-server -r /usr/local/bin/remux.sh'". Note the additional quotes, as otherwise -r will be passed to VDR and not to streamdev. 2.1 Compatibility: ------------------ This version is not compatible to VDR releases older than 1.7.25. Use one of the streamdev-0.5.x releases for older versions. 2.2 Compiling: -------------- The Makefiles are for VDR 1.7.36 and above. For VDR 1.7.33 and below, please replace the Makefiles in the main directory and in the client/ and server/ subdirectories with the corresponding Makefile-1.7.33 files. With VDR 1.7.34 and 1.7.35 YMMV ;) cd vdr-1.X.X/PLUGINS/src tar xvfz vdr-streamdev-0.5.0.tgz ln -s streamdev-0.5.0 streamdev cp -r streamdev/streamdev-server VDRCONFDIR/plugins/ cd ../.. make [options, if necessary] vdr make [options, if necessary] plugins To build only the plugin, change into the streamdev source folder and issue make To build only streamdev-server or only streamdev-client, use make server make client 2.3 Updating: -------------- If you are updating streamdev from an earlier release, you might have to perform some additional steps. Check which version you've been running before, then read below for the necessary changes. * Priorities: ------------- (Affected: 0.5.x and older) The server-side setting "Suspend behaviour" has been dropped in 0.6.0 in favour of priority based precedence. A priority of 0 and above means that clients have precedence. A negative priority gives precedence to local live TV on the server. So if "Suspend behaviour" was previously set to "Client may suspend" or "Never suspended", you will have to configure a negative priority. If the "Suspend behaviour" was set to "Always suspended", the default values should do. Configure the desired priorities for HTTP and IGMP Multicast streaming in the settings of streamdev-server. If you haven't updated all your streamdev-clients to at least 0.5.2, configure "Legacy Client Priority", too. In streamdev-client, you should set "Minimum Priority" to -99. Adjust "Live TV Priority" if necessary. * Location of files: -------------------- (Affected: 0.3.x, 0.4.x, 0.4.0pre, 0.5.0pre) Starting with streamdev 0.5.0, all additional files are kept in a directory called "streamdev-server" inside VDR's plugin config directory. It is the new default location of externremux.sh and the new place where streamdev-server expects the file "streamdevhosts.conf". You will have to move this file to its new location: streamdev 0.3.x: mv VDRCONFDIR/plugins/streamdevhosts.conf VDRCONFDIR/plugins/streamdev-server/ streamdev 0.4.x, 0.4.0pre and 0.5.0pre: mv VDRCONFDIR/plugins/streamdev VDRCONFDIR/plugins/streamdev-server/ Now check the contents of streamdevhosts.conf. Does it contain a "0.0.0.0/0" entry? If your VDR machine is connected to the Internet, this line gives *anyone* full access to streamdev, unless you took some other measures to prevent this (e.g. firewall). You might want to remove this line and enable HTTP authentication instead. * Handling of externremux script: --------------------------------- (Affected: 0.3.x, 0.4.0pre, 0.5.0pre) Streamdev server's externremux script became responsible for emitting all HTTP headers. A quick and dirty extension to your current script would be: echo -ne 'Content-type: video/mpeg\r\n' echo -ne '\r\n' However I encourage you to try the new externremux.sh script shipped with the streamdev source distribution. To emphasize the required change in externremux, the URL path for passing the stream through externremux has changed from EXTERN to EXT. 3. Usage: --------- Start the server core itself by specifying -Pstreamdev-server on your VDR commandline. To use the client core, specify -Pstreamdev-client. Both parts can run in one VDR instance, if necessary. Precedence between multiple clients and between client and server is controlled with priorities. For HTTP and IGMP Multicast, the priority is configured in streamdev-server's setup menu. A negative priority gives precedence to local live TV on the server. Zero and positive values give precedence to the client. The priority for VDR clients watching live TV is configured in the plugin setup of streamdev-client. For other client tasks (e.g. recording a client side timer) the same priority as on the client is used. With the parameter "Legacy client Priority" in streamdev-server's setup menu you can configure the priority for clients which cannot be configured to use negative priorities. It is used when an old client is detected an it requests priority "0". On the server, the main menu entry "Streamdev Connections" gives you a list of currently connected clients. Use the "red" key to terminate a connection. Note that depending on connection type and client, the client might re-connect sooner or later. The "blue" key in the server's main menu will suspend live TV on server. An image is displayed instead. This would allow a low priority client to switch to a different transponder. Enable "Client may suspend" in the server setup to allow VDR clients to suspend live TV remotely. In the server's setup there's also an option to suspend live TV when starting the server. The "auto" option will suspend live TV if there's no device with an MPEG decoder available which is typically the case on a headless server. NOTE: Precedence is mainly an issue on One-Card-Systems, since with multiple cards there is no need to switch transponders on the primary interface, if one of the other cards is idle (i.e. if it is not blocked by a recording). If all cards are in use (i.e. when something is recorded, or by multiple clients), this applies to Multiple-Card-Systems as well. If your client suffers from buffer underruns while watching live TV, you can configure buffering on the server side. Enter a reasonable value (e.g. 300ms) as "Live TV buffer delay (ms)" in the server setup. 3.1 Usage HTTP server: ---------------------- You can use the HTTP part by accessing the server with a HTTP-capable media player (such as XINE, MPlayer, and so on, if you have appropriate MPEG2-codecs installed). In the PlugIn's Setup, you can specify the port the server will listen to with the parameter "HTTP Server Port". The parameter "HTTP Streamtype" allows you to specify a default stream type, which is used if no specific type has been requested in the URL (see below). The supported stream types are: TS Transport Stream (i.e. a dump from the device) PES Packetized Elemetary Stream (VDR's native recording format) ES Elementary Stream (only Video, if available, otherwise only Audio) EXT Pass stream through external script (e.g. for converting with mencoder) Assuming that you leave the default port (3000), point your web browser to http://hostname:3000/ You will be presented a menu with links to various channel lists, including M3U playlist formats. If you don't want to use the HTML menu or the M3U playlists, you can access the streams directly like this: http://hostname:3000/3 http://hostname:3000/S19.2E-0-12480-898 The first one will deliver a channel by number on the server, the second one will request the channel by unique channel id. Use the special channel number 0 to see the server's current live TV channel. In addition, you can specify the desired stream type as a path to the channel. http://hostname:3000/TS/3 http://hostname:3000/PES/S19.2E-0-12480-898 The first one would deliver the stream in TS, the second one in PES format. Possible values are 'PES', 'TS', 'ES' and 'EXT'. You need to specify the ES format explicitly if you want to listen to radio channels. Play them back i.e. with mpg123. mpg123 http://hostname:3000/ES/200 With 'EXT' you can also add parameters which are passed as arguments to the externremux script (e.g. http://hostname:3000/EXT;param1=value1;param2=value2/3) Check your externremux.sh script for the parameters it understands. For details on how to modify or write your own externremux.sh, please see the chapter upon externremux.sh further down. If you want to access streamdev's HTTP server from the Internet, do *not* grant access for anyone by allowing any IP in "streamdevhosts.conf". Instead, pass the "-a" commandline option to streamdev-server. It takes a username and a password as argument. Clients with an IP not accepted by "streamdevhosts.conf" will then have to login. The VDR commandline will have to look like this: vdr ... -P 'streamdev-server -a vdr:secret' ... Note the single quotes, as otherwise "-a" will be passed to VDR and not to streamdev-server. The login ("vdr" in the example above) doesn't have to exist as a system account. 3.2 Usage IGMP multicast server: -------------------------------- IGMP based multicast streaming is often used by settop boxes to receive IP TV. Streamdev's multicast server allows you to feed live TV from VDR to such a settop box. VLC is known to work well if you look for a software client. The advantage of multicasting is that the actual stream is sent out only once, regardless of how many clients want to receive it. The downside is, that you cannot simply multicast across network boundaries. You need multicast routers. For multicast streaming over the public Internet you would even need to register for your own IP range. So don't even think of multicasting via Internet with streamdev! Streamdev will send the stream only to one local ethernet segment and all clients must be connected to this same segment. There must not be a router in between. Also note that the client must not run on the streamdev-server machine. Each channel is offered on a different multicast IP. Channel 1 is available from multicast IP 239.255.0.1, channel 2 from 239.255.0.2 and so on. The upper limit is 239.255.254.255 which corresponds to channel 65279 (239.255.255.0/24 is reserved according to RFC-2365). Before you can use streamdev's multicast server, you might need to patch VDR. Binding an IGMP socket is a privileged operation, so you must start VDR as root. The multicast server is disabled by default. Enter the streamdev-server setup menu to enable it and - IMPORTANT - bind the multicast server to the IP of your VDR server's LAN ethernet card. The multicast server will refuse to start with the default bind address "0.0.0.0". Now edit your streamdevhosts.conf. To allow streaming of all channels, it must contain "239.255.0.0/16". Note that you cannot limit connections by client IP here. You can however restrict which channels are allowed to be multicasted. Enter individual multicast IPs instead of "239.255.0.0/16". By default, the linux kernel will refuse to join more than 20 multicast groups. You might want to increase this up to "number_of_channels + 1". Note that it's "number_of_channels", not "maximum_channel_number". #First 100 channels: bash# sysctl -w net.ipv4.igmp_max_memberships=101 #All channels: bash# COUNT=$(grep -c '^[^:]' PATH_TO_YOUR/channels.conf) bash# sysctl -w net.ipv4.igmp_max_memberships=$((COUNT + 1)) You need to run the sysctl command *before* VDR is started. The setting is lost after the next reboot. Check the documentation of your Linux distro on how to make the setting persist (i.e. have your distro change the value for you as part of the boot procedure). Most likely /etc/sysctl.conf is your friend. A multicast server never knows how many clients are actually receiving a stream. If a client signals that it leaves a multicast group, the server has to query for other listeners before it can stop the stream. This may delay zapping from one transponder to an other. The client will probably requests the new channel before the previous stream has been stopped. If there's no free DVB card, VDR won't be able to fulfill the request until a DVB card becomes available and the client resends the request. 3.3 Usage VDR-to-VDR server: ---------------------------- You can activate the VDR-to-VDR server part in the PlugIn's Setup Menu. It is deactivated by default. The Parameter "VDR-to-VDR Server Port" specifies the port where you want the server to listen for incoming connections. The server will be activated when you push the OK button inside the setup menu, so there's no need to restart VDR. If both, streamdev-client and streamdev-server are installed, the additional option "Loop prevention" will show up in the streamdev-server setup. If enabled, streamdev-client won't be considered when streamdev-server is looking for a device which is able to receive some channel. This is required if two or more VDRs mutually share their DVB devices through streamdev. Otherwise you would end up in a loop. 3.4 Usage VDR-to-VDR client: ---------------------------- Streamdev-client adds a "Suspend Server" item to VDR's mainmenu. With the setup parameter "Hide Mainmenu Entry" you can hide this menu item if you don't need it. "Suspend Server" is only useful if the server runs in "Offer suspend mode" with "Client may suspend" enabled. The parameter "Remote IP" uses an IP-Address-Editor, where you can just enter the IP number with the number keys on your remote. After three digits (or if the next digit would result in an invalid IP address, or if the first digit is 0), the current position jumps to the next one. You can change positions with the left and right buttons, and you can cycle the current position using up and down. To confirm the entered address, press OK. So, if you want to enter the IP address "127.0.0.1", just mark the corresponding entry as active and type "127001" on your remote. If you want to enter "192.168.1.12", type "192168112". The parameters "Remote IP" and "Remote Port" in the client's setup specify the address of the remote VDR-to-VDR server to connect to. The client is disabled by default, because it wouldn't make much sense to start the client without specifying a server anyway. Activate the client by setting "Simultaneously used Devices" to at least 1. Streamdev-client will allocate as many VDR devices as you configure here. Each of these devices opens one connection to the server and becomes associated with one of the server's devices (typically a DVB card) on demand. Only the needed PIDs are transferred, and additional PIDs can be turned on during an active transfer. This makes it possible to switch languages, receive additional channels on the same transponder and use plugins that use receivers themselves (like osdteletext). So for viewing live TV a single device is sufficient. But if the client needs to receive channels from different transponders simultaneously (e.g. for PiP or client side recordings) a second device becomes necessary. To allocate additional devices, just increase the number and push the OK button. There's no need to restart VDR. Deleting VDR devices on-the-fly is not possible. However requests to switch channels will be refused by redundant devices. The default timeout of 2 seconds for network operations should be sufficient in most cases. Increase "Timeout" if you get frequent timeout errors in the log. With "Filter Streaming" enabled, the client will receive meta information like EPG data and service information, just as if the client had its own DVB card. Link channels and even a client-side EPG scan have been reported to work. If you have TV programs with dynamically changing PIDs (such as some german regional programs like NDR), then you need to enable "Filter Streaming" to correctly receive them. You also need to set in VDRs DVB setup the option "Update channels" to at least "PIDs only" (or "names and PIDs") for this to work. "Filter streaming" uses internally a socketpair(2) to copy meta data to VDR. This socketpair may require larger than default buffering. If you see a mesage like the following in syslog, cStreamdevFilter::PutSection(Pid:18 Tid: 64): Dropped 2995 bytes, max queue: 328640 then you should increase the streamdev client "FilterSockBufSize" value. A good value is 3072000. You will need to first configure your linux to permit such a large buffer size: sysctl net.core.wmem_max=3072000 The precedence among multiple client VDRs receiving live TV from the same server is controlled with "Live TV Priority". With "Maximum Priority" and "Minimum Priority" you can keep VDR from considering streamdev in certain cases. If for instance you have a streamdev client with its own DVB card, VDR might use streamdev for recording. If this is not what you want, you could set the maximum priority to 0. As recordings usually have a much higher priority (default 50), streamdev is now no longer used for recordings. The two parameters define the inclusive range of priorities for which streamdev will accept to tune. Setting the minimum priority to a higher value than the maximum, you will get two ranges: "up to maximum" and "minimum and above". You can also configure the "Broadcast Systems / Cost" of the streamdev-client device. On a pure streamdev-client only system it doesn't matter what you configure here. But if your client is equipped with a DVB card, you should read on. VDR always prefers the cheapest device in terms of supported broadcast systems and modulations. A DVB-S2 card supports two broadcast systems (DVB-S and DVB-S2). The supported modulations are counted as well (QPSK, QAM32/64/128/256, VSB8/16, TURBO_FEC). So for a DVB-S2 card which does QPSK you'll get a total cost of three. A DVB-C card (one broadcast system) which can do QAM32, QAM64, QAM128, QAM256 would give you a total of five. Check your log for "frontend ... provides ... with ..." messages to find out the cost of your DVB cards. Then pick a suitable value for streamdev-client. With equal costs, VDR will usually prefer the DVB card and take streamdev for recordings. If streamdev's costs are higher, live TV will use your DVB card until a recordings kicks in. Then the recording will take the DVB card and live TV will be shifted to streamdev (you'll notice a short interruption of live TV). To receive channels from multiple servers, create additional instances of the streamdev-client plugin. Simply copy (don't link!) the binary to a different name (e.g. streamdev-client2): cd VDRPLUGINLIBDIR cp libvdr-streamdev-client.so.1.X.X libvdr-streamdev-client2.so.1.X.X Now add -Pstreamdev-client2 to the VDR commandline. In the VDR plugin setup a second streamdev-client entry should show up. Both instances have to be configured individually. 4. Other useful Plugins: ------------------------ 4.1 Plugins for VDR-to-VDR clients: ----------------------------------- The following plugins are useful for VDR-to-VDR clients (i.e. VDRs running the streamdev-client): * remotetimers (http://vdr.schmirler.de/) Add, edit, delete timers on client and server * timersync (http://phivdr.dyndns.org/vdr/vdr-timersync/) Automatically syncronizes timer lists of client and server. All recordings will be made on the server * remoteosd (http://vdr.schmirler.de/) Provides access to the server's OSD menu * epgsync (http://vdr.schmirler.de/) Import EPG from server VDR * femon (http://www.saunalahti.fi/~rahrenbe/vdr/femon/) Display signal information from server's DVB card. SVDRP support must be enabled in femon's setup 4.2 Plugins for Server: ----------------------- * dummydevice (http://phivdr.dyndns.org/vdr/vdr-dummydevice/) Recommended on a headless server (i.e. a server with no real output device). Without this plugin, a budget DVB card could become VDR's primary device. This causes unwanted sideeffects in certain situations. 4.3 Alternatives: ----------------- * xineliboutput (http://phivdr.dyndns.org/vdr/vdr-xineliboutput/) With its networking option, xineliboutput provides an alternative to streamdev. You will get the picture of the server VDR, including its OSD. However you won't get independent clients, as they all share the same output. 5. externremux.sh: ------------------ When selecting streamtype "EXT", the TS stream from VDR is passed through an external program for further processing. By default a script installed at VDRCONFDIR/plugins/streamdev/externremux.sh is expected, however you may specify a different location as parameter -r to the streamdev-server plugin (see chapter upon Installation above). The TS stream is passed to the script on stdin, the resulting stream is expected on stdout. The following parameters are passed to the script in the environment: * Information on the channel: REMUX_CHANNEL_ID VDR channel ID REMUX_CHANNEL_NAME Channel name REMUX_VTYPE Video type (2 for MPEG-2) REMUX_VPID Video PID (undefined if audio only) REMUX_PPID PCR PID (undefined if equal to VPID) REMUX_TPID Teletext PID (undefined if not available) REMUX_APID Space separated list of audio pids REMUX_ALANG Space separated list of audio languages REMUX_DPID Space separated list of dolby pids REMUX_DLANG Space separated list of dolby languages REMUX_SPID Space separated list of subtitle pids REMUX_SLANG Space separated list of subtitle languages REMUX_PARAM_* All (user supplied) parameters (e.g. REMUX_PARAM_x) * Information on the connection (CGI like) REMOTE_ADDR Client IP SERVER_NAME Local IP SERVER_PORT Local port SERVER_PROTOCOL Streamdev protocol (HTTP, VTP, IGMP) SERVER_SOFTWARE Streamdev version All HTTP headers converted to uppercase, '-' replaced by '_' (e.g. USER_AGENT) The script should perform the following steps (pseudocode): if (SERVER_PROTOCOL == HTTP) write headers (including Content-Type) to STDOUT write empty line to STDOUT if (REQUEST_METHOD == HEAD) exit endif endif while (read STDIN) remux to STDOUT wend onSIGINT/SIGKILL: cleanup and exit 6. Known Problems: ------------------ * In VDR before 1.7.30 viewing encrypted channels is an issue as Streamdev doesn't provide a (dummy) CAM. So out of the box, VDR won't ever try to receive encrypted channels from streamdev. Pick one of the following solutions to work around the problem: 1. Force VDR to use streamdev. Open the channels menu on the client (or edit its channels.conf if you know how to do this) and set the CA field of all channels that only the server can decrypt to streamdev's device index. Usually streamdev will get number 9 or 10. Streamdev logs the actual device number when starting up. So please consider the logs for the correct value. Remember to fill in hexadecimal values if you are using an editor to modify your channels.conf (number 10 becomes an "a", number 11 a "b", ...). 2. Apply either patch "patches/vdr-1.6.0-1.7.29-intcamdevices.patch" or patch "patches/vdr-1.6.0-1.7.29-ignore_missing_cam.diff" to your client VDR. Intcamdevices is the clean solution, but it modifies the VDR API. So you will need to recompile all of your plugins. The ignore_missing_cam patch is trivial, no need to recompile other plugins. However it is not suitable for clients with a DVB card of their own. vdr-plugin-streamdev/common.c0000644000175000017500000000557513276341255016141 0ustar tobiastobias/* * $Id: common.c,v 1.12 2010/07/19 13:49:24 schmirl Exp $ */ #include #include #include "common.h" #include "tools/select.h" using namespace std; const char *VERSION = "0.6.1-git"; const char cMenuEditIpItem::IpCharacters[] = "0123456789."; cMenuEditIpItem::cMenuEditIpItem(const char *Name, char *Value): cMenuEditItem(Name) { value = Value; curNum = -1; pos = -1; step = false; Set(); } cMenuEditIpItem::~cMenuEditIpItem() { } void cMenuEditIpItem::Set(void) { char buf[1000]; if (pos >= 0) { in_addr_t addr = inet_addr(value); if ((int)addr == -1) addr = 0; int p = 0; for (int i = 0; i < 4; ++i) { p += snprintf(buf + p, sizeof(buf) - p, pos == i ?

The localchannelprovide patch became obsolete with VDR 1.7.21. - Added option to suspend live TV when the server starts - Set device occupied when streamdev switches away LiveTV on the server, to reduce the risk that the VDR main loop immediately switches back, resulting in a black screen on the client (reported by hummel99) - Fixed channel switch issues with priority > 0 (reported by hummel99) - Removed noisy debug messages - Fixed HTTP menu destruction - API change of VDR 2.1.2 - Fixed priority handling, messed up when adding multi-device support - Added HTTP "Server" header (suggested by hivdr) - Ignore dummy file extensions (.ts, .vob, .vdr) when parsing HTTP URIs - Select start position for replaying a recording by parameter pos=. Supported values are resume, mark.#, time.#, frame.# or a plain # representing a percentage if < 100 or a byte position otherwise (thanks to hivdr) - Start cSuspendCtl hidden or it will prevent idle shutdown (thanks to thomasjfox) - Fixed recordings menu inode numbers: ino_t is a long long on some systems - Updated Slovak translation (thanks to Milan Hrala) - Adapted Makefiles to VDR 1.7.36+ (thanks to macmenot). Old makefiles have been renamed to Makefile-1.7.33. - API changes of VDR 1.7.38 (thanks to mal@vdr-developer) - Added simple recordings menu in HTTP server - Restructured menuHTTP classes - Added RSS format for HTTP menus - Recordings can now also be selected by struct stat "st_dev:st_ino.rec" - Implemented multi-device support for streamdev client (suggested by johns) - Basic support for HTTP streaming of recordings - Close writer when streamer is finished - Don't abort VTP connection if filter stream is broken - Restructured cStreamdevStreamer: Moved inbound buffer into actual subclass. - In cStreamdevStreamer dropped Activate(bool) and moved its code into Start(). - Moved cStreamdevFilterStreamer to livefilter.[hc] - Return HTTP/1.1 compliant response headers plus some always useful headers - Return HTTP URL parameters ending with ".dlna.org" as response headers - Store HTTP URL parameters in a map - Support HTTP HEAD requests with external remuxer - Fixed always using priority 0 for HTTP HEAD requests - Start writer right after creating it - Corrected typos (thanks to Ville Skyttä) - Fixed compiler error in client/device.c with VDR < 1.7.22 (reported by Uwe@vdrportal) - Updated Italian translation (thanks to Diego Pierotto) - Added DeviceName() and DeviceType() to client device. The server IP and the number of the device used on the server are returned respectively. 2012-05-29: Version 0.6.0 - Reimplemented some client device methods - Proper fix for "client sends ABRT after TUNE". Obsoletes many hacks in client - Added CLOCK_MONOTONIC timestamp and thread id to Dprintf - Silenced warning (thanks to Rolf Ahrenberg) - Updated Finnish translation (thanks to Rolf Ahrenberg) - Replaced server-side suspend modes with priority based precedence handling - Client-side priority handling for VDR >= 1.7.25 and servers running VTP > 1.0 - Introduced VTP protocol version numbering for easier compatibility handling between different client and server versions. The server includes the protocol version in its greeting string, the client reports its version with the new command "VERS". - Dropped compatibility of streamdev-server with VDR < 1.7.25 2012-05-12: Version 0.5.2 - Use fileno() to retrieve the fd from a FILE structure (submitted by an anonymous user) - New special meaning "show current channel" when channel 0 is requested.

Please update "Minimum Priority" in streamdev-client setup. - Use the new streamdev-client setup option "Live TV Priority" to control precedence among multiple clients. The VDR option "Primary Limit" which has previouly been used for this purpose has been dropped in VDR 1.7.25. - Timout for network operations now configurable in streamdev-client setup - Added timeout to Connect() - Report the server-side HTTP status "503 Service unavailable" instead of the client-side error "409 Conflict" when a channel is unavailable (suggested by Methodus) - Update of po headers and Finnish translation (thanks to Rolf Ahrenberg) - support for non-cycle-free setups (e.g. where two VDRs mutually share their DVB cards through streamdev-client/-server). Must be enabled in streamdev-server setup. Obsoletes recursion patches. - API change of VDR 1.7.22 - VDR 1.7.22 obsoletes cap_net_raw patch. Added cap_net_raw patch for VDR 1.7.5 - 1.7.21. - Update and UTF-8 conversion of Finnish po files (thanks to Rolf Ahrenberg) - Added "Hide mainmenu entry" option on server (thanks to Rolf Ahrenberg) - Added server menu with list of clients. Connections can be terminated with the "red" key. The former main menu action of suspending live TV moved to the "blue" key. - code cleanup and optimization (thanks to Ville Skyttä) - properly shutdown IGMP timeout handler thread when the plugin is stopped. Fixes occasional segfaults on VDR exit. - fixed memory leak in libdvbmpeg read_pes (thanks to Ville Skyttä) - dropped several unused functions in libdvbmpeg - restricted VTP command RENR to liemikuutio patch < 1.32. Build fails with newer versions of this patch (thanks to Ville Skyttä) - updated outdated COPYING file and FSF address (thanks to Ville Skyttä) - include SDT and TDT in TS streams - the icy-name HTTP header sent with radio streams makes VLC pick the wrong demuxer. Send icy-name only for ES audio streams. - fixed regression of "live TV must be switched in VDR main thread" change: deadlock in IGMP streaming server when switching live TV. - streamdev-client returns true in its AvoidRecording() method introduced with VDR 1.7.19. Note however that the impact of NumProvidedSystems is higher. - updated device selection to code of VDR 1.7.19 - adaption to VDR 1.7.12 cReceiver API change - increased WRITERBUFSIZE. Has been reported to fix some ringbuffer overflows (thanks to Lubo¨ Dole¸el) - check availability of channel if VTP command TUNE is called without prior PROV call (e.g. client side EPG scan) - added support for VDR 1.7.19 SignalStrength/SignalQuality - analog video channels use the same transponder and pid for different channels, so streamdev-client must always issue TUNE command - server must close the VTP connection also if filter stream is broken - fixed missing #ifdefs for new NumProvidedSystems setup option - new externremux.sh mencoder config options: audio pid by language code (-alang) and verbosity (-msglevel) (thanks to Pekko Tiitto) - writer must not spend too much time waiting in select() without checking if the thread has been cancelled - added Spanish translation (thanks to Javier Bradineras) - live TV must be switched in VDR main thread - dropped compatibility with VDR < 1.5.16 - return value of streamdev-clients cDevice::NumProvidedSystems() now configurable in plugin setup 2011-02-11: Version 0.5.1 - updated copy of GetClippedNumProvidedSystems to the version used since VDR 1.7.15 (reported by carel@vdrportal) - fixed the code deciding if a device is in use for live TV or not.

The server stores channel and priority requested with the PROV command and re-uses these values in a subsequent TUNE for the same channel. The new PRIO command is used to update the receiver's priority if necessary. - added parameter HEIGHT to externremux.sh - fixed syslog messages reporting local instead of remote IP and port - fixed regression of the GetDevice(...) change. Filter streaming to clients with a recent VDR version no longer worked. - log an error if externremux.sh is missing or not executable - since VDR 1.5.0 cDevice::GetDevice(...) is no longer a query only method. It detaches all receivers of the device it returns. So it is no longer suitable for testing the availability of a device. Added a copy of VDR's cDevice::GetDevice(...) without the detach receivers part as a workaround until a better solution is available - added dsyslog messages to help troubleshouting channel switch issues - VTP command SUSP didn't attach the player to the primary device - fixed incompatibilities with older make versions - replacing a connections receiver is now an atomic operation. Solves stuttering audio/video due to lost TS packets when adding/removing PIDs - disabled attribute warn_unused_result in libdvbmpeg - slightly increased thread priorities of cStreamdevWriter/Streamer (suggested by Rolf Ahrenberg) - fixed missing support for invisible channel groups (groups without name) in HTTP menu (reported by Timothy D. Lenz) - don't quote actual program call in externremux.sh, so you can run the program through e.g. nice or taskset just by extending the variable which holds the program name - in externremux.sh each mencoder audio and video codec has a dedicated variable for a default option string now. Still you can override each default option with an URL parameter - externremux.sh mencoder now uses scale parameter with negative height instead of -xy for scaling (suggested by vel_tins@vdrportal) - added FPS (frames per second) parameter to externremux.sh (suggested by vel_tins@vdrportal) - don't use std::map.at(). It's not available in older libstdc++ version (reported by Matthias Prill) - fixed extremux x264 using value of ABR for VBR (thanks to vel_tins@vdrportal) 2010-07-20: Version 0.5.0b - fixed wrong URL path in m3u playlists (reported by Norman Thiel) 2010-07-20: Version 0.5.0a - set externremux.sh executable in distribution archive - externremux quality value should be wlan54, not wlan45 (reported by wolfi.m@vdrportal) 2010-07-19: Version 0.5.0 - using SIGINT in externremux to kill mencoder works better than SIGTERM; especially x264 still needs a SIGKILL sometimes - added --remove-destination to cp commands installing plugins - fixed "plugin doesn't honor APIVERSION" (reported by carel@vdrportal) - updated Italian translation (thanks to Diego Pierotto) - config option "client may suspend" hidden if not applicable - updated and enhanced README - separated language resources of client and server - restructured build process - added support for HTTP method HEAD - rewrite of externremux.sh, including support for various URL parameters, logging and improved shutdown - start externremux script in a separate process group - changed HTTP URL path for externremux from EXTERN to EXT (suggested by Rolf Ahrenberg) - HTTP headers now have to be emitted by externremux script - pass channel related information and URL parameters to externremux script through environment - implement CGI like interface for externremux script - dropped "Synchronize EPG" feature.

I hope that's not already claimed by someone ;). This Protocol was created for Video Transfers over a Network. It is a text- based protocol like the FTP, and is used by a client to communicate with a server providing different types of video data, such as live streams, recordings or disc media. The basic communication consists of short text commands sent by the client, answered by numerical codes accompanied by human-readable messages. All messages should be finished by a full CR/LF line-ending, which should preferably written as "\015\012", as this is fully platform-independent. Nevertheless, a client or (especially) a server should also act on "\n" line-endings. The MPEG data is being transmitted over a separate data connection. TODO: - PORT behaviour changed - TUNE syntax changed - connection IDs - new command PLAY Response Code Summary Code Meaning 220 Last command ok / connection ready 221 Service is closing the connection afterwards 500 The command was not recognized 501 The parameters couldn't be interpreted correctly 550 Action not taken, for various reason 551 Action not taken, a subsequent connection was unsuccessful 560 Live-Stream not available currently [changed in 0.0.3] 561 Capability not known [new in 0.0.2] 562 Pid currently not available [new in 0.0.3] 563 Stream not available currently [new in 0.0.3] Command Reference Command: Connect to VTP Server Responses: 220 - The server is ready Description: Upon connection to the server (which usually listens at port 2004), the first thing the client has to expect is a welcome message with the "220" response code. The client may now send a CAPS command, to tell the server it's capabilities. Command: CAPS Responses: 220 - This capability is known and will be used from now on. 561 - This capability is unknown, try anotherone Description: This command tells the server to serve media data in a specific format, like "PES" (for MPEG2-PES) or "TS" (for MPEG2-TS). A client can do several CAPS commands until the server accepts one. So a client should try all formats it can handle, descending from the most preffered one. If no such command is sent, streaming is defaulted to PES. Capabilities currently used: TS Transport Stream (all PIDs belonging to a channel) TSPIDS Only in conjunction with TS: Stream PIDs separately upon request (this enables the ADDP/DELP commands) PES Program Elementary stream (Video and primary Audio stream) [new in 0.0.2,updated in 0.0.3] Command: PROV Responses: 220 - Media available for receive 501 - The parameters were incorrect 550 - The media couldn't be identified 560 - This server can currently not serve that media Description: With this command, the server is asked if the given media can be received. The Priority is a number between 0 and 100 (in case a media can not be received by an unlimited number of clients, the server shall grant higher priorities before lower ones, and it shall also quit streams with lower permissions if a higher one is requested), or -1 to ask the server if this media is available at all. The Media is a string defining the wanted media type. This is currently for free use, it could for example carry a VDR unique channel id, to specify a TV channel. Command: PORT
    Responses: 220 - The data connection was opened 501 - The parameter list was wrong 551 - The data connection was refused by the client or timed out Description: The PORT command tells the server the target of a following media transmission. The parameter Id specifies an index which is used to establish multiple data connections over one control connection. It is used later in the ABRT command to close a specific data connection. The second parameter argument has six comma-separated fields, of which the first four represent the target IP address, in the byte-order as the dot-notation would be printed. The last two fields represent the target port, with the high-byte first. To calculate the actual values, you could use the following: Field(5) = (RealPort & 0xFF00) shr 8 Field(6) = RealPort & 0xFF Reversed: RealPort = (Field(5) shl 8) + Field(6) After receiving the port command, the data connection is opened but no data is transferred, yet. Id's currently used: 0 Data connection for live streams 1 Data connection for saved streams [changed in 0.0.3] Command: TUNE Responses: 220 - Data connection was opened successfully 550 - The media couldn't be identified 560 - The live stream is unavailable Description: This command tells the media server to start the transfer over a connection to a remote target established by the PORT command before. Please look at the PROV command for the meaning of the parameters. The server begins to send MPEG data. After the transfer has been started, the response code "220" is sent. Command: ADDP Responses: 220 - The requested Pid is transferring 560 - The requested Pid is not available currently Description: This tells the server to start the transfer of a specific Pid over a data connection established by the PORT command before. Command: DELP Responses: 220 - The requested Pid is transferring 560 - The requested Pid was not transferring Description: This tells the server to stop the transfer of a specific Pid enabled by DELP before. Command: ABRT Responses: 220 - Data connection closed Description: This one should be sent before requesting another media or when a media isn't needed anymore. It terminates the data connection previously opened by PORT. Command: QUIT Responses: 221 - Connection is being closed afterwards Description: This commands terminates the client connection.
