Basic Installation ================== Briefly, the shell commands `./configure; make; make install' should configure, build, and install this package. The following more-detailed instructions are generic; see the `README' file for instructions specific to this package. Some packages provide this `INSTALL' file but do not implement all of the features documented below. The lack of an optional feature in a given package is not necessarily a bug. More recommendations for GNU packages can be found in *note Makefile Conventions: (standards)Makefile Conventions. The `configure' shell script attempts to guess correct values for various system-dependent variables used during compilation. It uses those values to create a `Makefile' in each directory of the package. It may also create one or more `.h' files containing system-dependent definitions. Finally, it creates a shell script `config.status' that you can run in the future to recreate the current configuration, and a file `config.log' containing compiler output (useful mainly for debugging `configure'). It can also use an optional file (typically called `config.cache' and enabled with `--cache-file=config.cache' or simply `-C') that saves the results of its tests to speed up reconfiguring. Caching is disabled by default to prevent problems with accidental use of stale cache files. If you need to do unusual things to compile the package, please try to figure out how `configure' could check whether to do them, and mail diffs or instructions to the address given in the `README' so they can be considered for the next release. If you are using the cache, and at some point `config.cache' contains results you don't want to keep, you may remove or edit it. The file `configure.ac' (or `configure.in') is used to create `configure' by a program called `autoconf'. You need `configure.ac' if you want to change it or regenerate `configure' using a newer version of `autoconf'. The simplest way to compile this package is: 1. `cd' to the directory containing the package's source code and type `./configure' to configure the package for your system. Running `configure' might take a while. While running, it prints some messages telling which features it is checking for. 2. Type `make' to compile the package. 3. Optionally, type `make check' to run any self-tests that come with the package, generally using the just-built uninstalled binaries. 4. Type `make install' to install the programs and any data files and documentation. When installing into a prefix owned by root, it is recommended that the package be configured and built as a regular user, and only the `make install' phase executed with root privileges. 5. Optionally, type `make installcheck' to repeat any self-tests, but this time using the binaries in their final installed location. This target does not install anything. Running this target as a regular user, particularly if the prior `make install' required root privileges, verifies that the installation completed correctly. 6. You can remove the program binaries and object files from the source code directory by typing `make clean'. To also remove the files that `configure' created (so you can compile the package for a different kind of computer), type `make distclean'. There is also a `make maintainer-clean' target, but that is intended mainly for the package's developers. If you use it, you may have to get all sorts of other programs in order to regenerate files that came with the distribution. 7. Often, you can also type `make uninstall' to remove the installed files again. In practice, not all packages have tested that uninstallation works correctly, even though it is required by the GNU Coding Standards. 8. Some packages, particularly those that use Automake, provide `make distcheck', which can by used by developers to test that all other targets like `make install' and `make uninstall' work correctly. This target is generally not run by end users. Compilers and Options ===================== Some systems require unusual options for compilation or linking that the `configure' script does not know about. Run `./configure --help' for details on some of the pertinent environment variables. You can give `configure' initial values for configuration parameters by setting variables in the command line or in the environment. Here is an example: ./configure CC=c99 CFLAGS=-g LIBS=-lposix *Note Defining Variables::, for more details. Compiling For Multiple Architectures ==================================== You can compile the package for more than one kind of computer at the same time, by placing the object files for each architecture in their own directory. To do this, you can use GNU `make'. `cd' to the directory where you want the object files and executables to go and run the `configure' script. `configure' automatically checks for the source code in the directory that `configure' is in and in `..'. This is known as a "VPATH" build. With a non-GNU `make', it is safer to compile the package for one architecture at a time in the source code directory. After you have installed the package for one architecture, use `make distclean' before reconfiguring for another architecture. On MacOS X 10.5 and later systems, you can create libraries and executables that work on multiple system types--known as "fat" or "universal" binaries--by specifying multiple `-arch' options to the compiler but only a single `-arch' option to the preprocessor. Like this: ./configure CC="gcc -arch i386 -arch x86_64 -arch ppc -arch ppc64" \ CXX="g++ -arch i386 -arch x86_64 -arch ppc -arch ppc64" \ CPP="gcc -E" CXXCPP="g++ -E" This is not guaranteed to produce working output in all cases, you may have to build one architecture at a time and combine the results using the `lipo' tool if you have problems. Installation Names ================== By default, `make install' installs the package's commands under `/usr/local/bin', include files under `/usr/local/include', etc. You can specify an installation prefix other than `/usr/local' by giving `configure' the option `--prefix=PREFIX', where PREFIX must be an absolute file name. You can specify separate installation prefixes for architecture-specific files and architecture-independent files. If you pass the option `--exec-prefix=PREFIX' to `configure', the package uses PREFIX as the prefix for installing programs and libraries. Documentation and other data files still use the regular prefix. In addition, if you use an unusual directory layout you can give options like `--bindir=DIR' to specify different values for particular kinds of files. Run `configure --help' for a list of the directories you can set and what kinds of files go in them. In general, the default for these options is expressed in terms of `${prefix}', so that specifying just `--prefix' will affect all of the other directory specifications that were not explicitly provided. The most portable way to affect installation locations is to pass the correct locations to `configure'; however, many packages provide one or both of the following shortcuts of passing variable assignments to the `make install' command line to change installation locations without having to reconfigure or recompile. The first method involves providing an override variable for each affected directory. For example, `make install prefix=/alternate/directory' will choose an alternate location for all directory configuration variables that were expressed in terms of `${prefix}'. Any directories that were specified during `configure', but not in terms of `${prefix}', must each be overridden at install time for the entire installation to be relocated. The approach of makefile variable overrides for each directory variable is required by the GNU Coding Standards, and ideally causes no recompilation. However, some platforms have known limitations with the semantics of shared libraries that end up requiring recompilation when using this method, particularly noticeable in packages that use GNU Libtool. The second method involves providing the `DESTDIR' variable. For example, `make install DESTDIR=/alternate/directory' will prepend `/alternate/directory' before all installation names. The approach of `DESTDIR' overrides is not required by the GNU Coding Standards, and does not work on platforms that have drive letters. On the other hand, it does better at avoiding recompilation issues, and works well even when some directory options were not specified in terms of `${prefix}' at `configure' time. Optional Features ================= If the package supports it, you can cause programs to be installed with an extra prefix or suffix on their names by giving `configure' the option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'. Some packages pay attention to `--enable-FEATURE' options to `configure', where FEATURE indicates an optional part of the package. They may also pay attention to `--with-PACKAGE' options, where PACKAGE is something like `gnu-as' or `x' (for the X Window System). The `README' should mention any `--enable-' and `--with-' options that the package recognizes. For packages that use the X Window System, `configure' can usually find the X include and library files automatically, but if it doesn't, you can use the `configure' options `--x-includes=DIR' and `--x-libraries=DIR' to specify their locations. Some packages offer the ability to configure how verbose the execution of `make' will be. For these packages, running `./configure --enable-silent-rules' sets the default to minimal output, which can be overridden with `make V=1'; while running `./configure --disable-silent-rules' sets the default to verbose, which can be overridden with `make V=0'. Particular systems ================== On HP-UX, the default C compiler is not ANSI C compatible. If GNU CC is not installed, it is recommended to use the following options in order to use an ANSI C compiler: ./configure CC="cc -Ae -D_XOPEN_SOURCE=500" and if that doesn't work, install pre-built binaries of GCC for HP-UX. On OSF/1 a.k.a. Tru64, some versions of the default C compiler cannot parse its `' header file. The option `-nodtk' can be used as a workaround. If GNU CC is not installed, it is therefore recommended to try ./configure CC="cc" and if that doesn't work, try ./configure CC="cc -nodtk" On Solaris, don't put `/usr/ucb' early in your `PATH'. This directory contains several dysfunctional programs; working variants of these programs are available in `/usr/bin'. So, if you need `/usr/ucb' in your `PATH', put it _after_ `/usr/bin'. On Haiku, software installed for all users goes in `/boot/common', not `/usr/local'. It is recommended to use the following options: ./configure --prefix=/boot/common Specifying the System Type ========================== There may be some features `configure' cannot figure out automatically, but needs to determine by the type of machine the package will run on. Usually, assuming the package is built to be run on the _same_ architectures, `configure' can figure that out, but if it prints a message saying it cannot guess the machine type, give it the `--build=TYPE' option. TYPE can either be a short name for the system type, such as `sun4', or a canonical name which has the form: CPU-COMPANY-SYSTEM where SYSTEM can have one of these forms: OS KERNEL-OS See the file `config.sub' for the possible values of each field. If `config.sub' isn't included in this package, then this package doesn't need to know the machine type. If you are _building_ compiler tools for cross-compiling, you should use the option `--target=TYPE' to select the type of system they will produce code for. If you want to _use_ a cross compiler, that generates code for a platform different from the build platform, you should specify the "host" platform (i.e., that on which the generated programs will eventually be run) with `--host=TYPE'. Sharing Defaults ================ If you want to set default values for `configure' scripts to share, you can create a site shell script called `config.site' that gives default values for variables like `CC', `cache_file', and `prefix'. `configure' looks for `PREFIX/share/config.site' if it exists, then `PREFIX/etc/config.site' if it exists. Or, you can set the `CONFIG_SITE' environment variable to the location of the site script. A warning: not all `configure' scripts look for a site script. Defining Variables ================== Variables not defined in a site shell script can be set in the environment passed to `configure'. However, some packages may run configure again during the build, and the customized values of these variables may be lost. In order to avoid this problem, you should set them in the `configure' command line, using `VAR=value'. For example: ./configure CC=/usr/local2/bin/gcc causes the specified `gcc' to be used as the C compiler (unless it is overridden in the site shell script). Unfortunately, this technique does not work for `CONFIG_SHELL' due to an Autoconf bug. Until the bug is fixed you can use this workaround: CONFIG_SHELL=/bin/bash /bin/bash ./configure CONFIG_SHELL=/bin/bash `configure' Invocation ====================== `configure' recognizes the following options to control how it operates. `--help' `-h' Print a summary of all of the options to `configure', and exit. `--help=short' `--help=recursive' Print a summary of the options unique to this package's `configure', and exit. The `short' variant lists options used only in the top level, while the `recursive' variant lists options also present in any nested packages. `--version' `-V' Print the version of Autoconf used to generate the `configure' script, and exit. `--cache-file=FILE' Enable the cache: use and save the results of the tests in FILE, traditionally `config.cache'. FILE defaults to `/dev/null' to disable caching. `--config-cache' `-C' Alias for `--cache-file=config.cache'. `--quiet' `--silent' `-q' Do not print messages saying which checks are being made. To suppress all normal output, redirect it to `/dev/null' (any error messages will still be shown). `--srcdir=DIR' Look for the package's source code in directory DIR. Usually `configure' can determine that directory automatically. `--prefix=DIR' Use DIR as the installation prefix. *note Installation Names:: for more details, including other options available for fine-tuning the installation locations. `--no-create' `-n' Run the configure checks, but stop before creating any output files. `configure' also accepts some other, not widely useful, options.

It gives you an easy, convenient way to say "open and decompress this media file for me, I don't care how you do it" and get frame- and sample-accurate access (usually), without having to bother with the sometimes less than straightforward and less than perfectly documented libav API. The library is written in C++, but the public API is pure C, so if you can link to a C library, you can use FFMS2. The source is available under the MIT license, but the license of the binaries depends on how libav was compiled. There are optional components that require a GPL libav, and if those are compiled in FFMS2 itself becomes covered by the GPL as well. ## Avisynth plugin For the end user, the most visible use of FFMS is the implementation of an [Avisynth](http://www.avisynth.org) source plugin that uses the FFMS library to open media files. This plugin is a part of the FFMS2 project and is available for download here; for documentation see the UserGuide. ### Features In addition to being able to open almost any common audio or video format, the Avisynth plugin has a number of more or less unique properties that other Avisynth source filters lack: * It is the only source filter that has support for Unicode filenames that are not representable in the system codepage. * It is the only source filter that has proper variable framerate (VFR) support. * It is the only general-purpose (i.e. not restricted to one or a few formats) source filter that will work reliably when running Avisynth under Wine. * It is the only general-purpose source filter that does not rely on external decoders. * It is (probably) the only source filter that supports mid-stream video resolution switches. ### Versions and variants If you're confused by all the different variants, here's a small explanation: * Vanilla (no suffix): standard 32-bit version. If you don't know what you want, you want this. * -x64: 64-bit version; mostly for use with 64-bit Avisynth. * -avs-cplugin: Variant of the Avisynth plugin written in C. Primary purpose is to get access to the new colorspaces available in Avisynth 2.6. * SDK: software developer's kit, for people who want to develop Windows applications that use FFMS2, using Microsoft Visual Studio 2008 or later. Packages marked rNUMBER are testing builds made in-between releases. Download them if you need some bleeding-edge feature or just want to test out the upcoming version. Do note that they may be less stable than the official release versions. ### Why is it called FFmpegSource, that makes no sense at all!?! FFMS originated as an Avisynth file reader plugin, and those are traditionally called FooSource, where Foo usually is the method used to open the file. For historical reasons the entire project is still called FFmpegSource, although these days the name is pretty misleading and makes people think it has something to do with FFmpeg's source code or somesuch. To avoid confusion, it's probably better to refer to the library as FFMS (2, since version 1 was only an Avisynth plugin...) and keep the FFmpegSource name for the Avisynth plugin. ffms2-2.19/aclocal.m4000066400000000000000000001445451221270604600143370ustar00rootroot00000000000000# generated automatically by aclocal 1.14 -*- Autoconf -*- # Copyright (C) 1996-2013 Free Software Foundation, Inc. # This file is free software; the Free Software Foundation # gives unlimited permission to copy and/or distribute it, # with or without modifications, as long as this notice is preserved. # This program is distributed in the hope that it will be useful, # but WITHOUT ANY WARRANTY, to the extent permitted by law; without # even the implied warranty of MERCHANTABILITY or FITNESS FOR A # PARTICULAR PURPOSE. m4_ifndef([AC_CONFIG_MACRO_DIRS], [m4_defun([_AM_CONFIG_MACRO_DIRS], [])m4_defun([AC_CONFIG_MACRO_DIRS], [_AM_CONFIG_MACRO_DIRS($@)])]) m4_ifndef([AC_AUTOCONF_VERSION], [m4_copy([m4_PACKAGE_VERSION], [AC_AUTOCONF_VERSION])])dnl m4_if(m4_defn([AC_AUTOCONF_VERSION]), [2.69],, [m4_warning([this file was generated for autoconf 2.69.

Also, it might not be ## supported by the other compilers which use the 'gcc' depmode. ## - Using -M directly means running the compiler twice (even worse ## than renaming). if test -z "$gccflag"; then gccflag=-MD, fi "$@" -Wp,"$gccflag$tmpdepfile" stat=$? if test $stat -ne 0; then rm -f "$tmpdepfile" exit $stat fi rm -f "$depfile" echo "$object : \\" > "$depfile" # The second -e expression handles DOS-style file names with drive # letters. sed -e 's/^[^:]*: / /' \ -e 's/^['$alpha']:\/[^:]*: / /' < "$tmpdepfile" >> "$depfile" ## This next piece of magic avoids the "deleted header file" problem. ## The problem is that when a header file which appears in a .P file ## is deleted, the dependency causes make to die (because there is ## typically no way to rebuild the header).

FFmpegSource2 API Documentation

FFmpegSource2 (FFMS2) is a wrapper library around Libav/FFmpeg, plus some additional components to deal with file formats libavformat has (or used to have) problems with. It gives you a convenient way to say "open and decompress this media file for me, I don't care how you do it", without having to bother with the sometimes less than straightforward and less than perfectly documented Libav/FFmpeg internals. May be frame and/or sample accurate on good days. The library is written in C++, but the public API is C-friendly and it is possible to simply include and link directly with a pure C application.

The source is MIT licensed and can be obtained from the Google Code project SVN; see http://code.google.com/p/ffmpegsource/source/checkout.

Limitations

FFMS2 does not mux or encode anything. FFMS2 does not give you fine control over codec internals. FFMS2 does not let you demux raw compressed data, you get it decompressed or not at all. FFMS2 does not provide you with a good solution for realtime playback, since it needs to index the input file before you can retreive frames or audio samples. FFMS2 does not currently handle things like subtitles, file attachments or chapters. FFMS2's video frame and audio sample retrieval functions are not threadsafe; you may only have one request going at a time.

Compilation

FFMS2 has the following dependencies:

  • Libav (sure, you can use the FFmpeg branch too if you really want)
    • At least 0.8 for libav and 0.9 for FFmpeg
    • Further recommended configuration options: --disable-debug --disable-muxers --disable-encoders --disable-filters --disable-hwaccels --disable-network --disable-devices --enable-runtime-cpudetect (runtime cpudetect in particular is a good idea if you are planning on distributing the library; not disabling debug results in a gigantic dll).
  • zlib

Compiling the library itself is fairly straightforward. For the basics, just add the include folder to your include paths and compile everything in src/core; everything else can be skipped. src/avisynth contains code for some Avisynth filters (optional and Windows-only); src/config is some (mostly autogenerated) configuration headers; and src/index is a stand-alone indexing application (built separately and linked against the main FFMS2 library).

Windows-specific compilation notes

If you're compiling the library on Windows, it is suggested that you use the Microsoft Visual Studio 2008 solution file from SVN. Any version of MSVC2008 and MSVC2010 should work for compiling it, including the free Express Edition (but if you use that you must undefine HAALISOURCE or find a copy of the ATL libraries). The project file in question assumes that you have compiled Libav with MinGW (guides on how to do that are easy to find) and want to link FFMS2 with it statically (linking it dynamically is possible but not recommended since it usually leads to DLL hell). If you're using FFmpeg (as opposed to Libav), uncomment #define FFMS_USE_FFMPEG_COMPAT in ffmscompat.h, as this is not always automatically detected. Add your mingw/include and mingw/lib folders to MSVC's respective global directory settings (Tools menu -> Options -> Projects and Solutions -> VC++ Directories) and you should be good to go.

Targetting x64 from msvc requires a little extra work. Building libav for x64 is much like for 32-bit, except with the relevant prefix information (which will be along the lines of --prefix=/mingw/x86_64-w64-mingw32/ --cross-prefix=x86_64-w64-mingw32- --arch=x86_64 --target-os=mingw32), and --extra-cflags="-D_SYSCRT" is required for the end result to be linkable from msvc. Note that you'll probably need to add /usr/local/x86_64-w64-mingw32/... to MSVC's directories rather than the usual paths.

If you're using anything else, you're on your own. It's possible to build the library using MinGW; there is an avisynth plugin available that uses the avisynth_c interface originally developed to target 64-bit avisynth (it is available in branches/c_plugin in svn). If you're rolling your own MSVC solution file, remember that you need to #define FFMS_EXPORTS somewhere when compiling the library. You may also #define HAALISOURCE if you want to make the library able to open MPEG TS/PS and OGM files using Haali's DirectShow splitter (if you do not define it, those files will be opened with libavformat instead, and that usually doesn't work out all that well). Note that if you do so, opening those files will fail unless the user has the Haali Media Splitter DirectShow filter installed. Both those defines are enabled by default in the solution file in SVN.

Quickstart guide for impatient people

If you don't want to know anything about anything and just want to open some video with FFMS2 in the absolutely simplest possible manner, without selective indexing, progress reporting, saved index files, keyframe or timecode reading or anything like that, here's how to do it with the absolutely bare minimum of code.

	if (trackno < 0) {
		/* no video tracks found in the file, this is bad and you should handle it */
		/* (print the errmsg somewhere) */
	}

	/* We now have enough information to create the video source object */
	FFMS_VideoSource *videosource = FFMS_CreateVideoSource(sourcefile, trackno, index, 1, FFMS_SEEK_NORMAL, &errinfo);
	if (videosource == NULL) {
		/* handle error (you should know what to do by now) */
	}

	/* Since the index is copied into the video source object upon its creation,

}

And that's pretty much it. Easy, ain't it?

Indexing and You

Before opening a media file with FFMS2, you must index it. This is to ensure that keyframe positions, timecode data and other interesting things are known so that frame-accurate seeking is easily possible.

There are two ways to index a media file. The first one is really a backwards compatibility thing and uses FFMS_MakeIndex. You call the function with the source filename, a binary mask representing which audio tracks you want to index (all video tracks are always automatically indexed since the operation can't fail and takes no additional time), another binary mask representing which audio tracks you want to dump to Wave64 files on disk, an optional progress reporting callback and a likewise optional audio dump filename generation callback; and it will create an index object. With this method there is no way of telling ahead of time how many tracks the file has and hence the only two masks that are useful in practice are 0 (index nothing) and -1 (index everything). If you want to index only certain tracks you will have to redo the indexing after examining the index. This indexing method may be used if you only want to index video tracks, or if you want all the audio tracks regardless of how many they are, or if you already know the track layout of the file you're going to open.

The other method is a bit more sophisticated. First, you create an indexer object using FFMS_CreateIndexer and the source filename. You can then examine the indexer using FFMS_GetNumTracksI, FFMS_GetTrackTypeI and FFMS_GetCodecNameI to determine how many tracks there are and what their respective types are. When you have done so, you call FFMS_DoIndexing, which is exactly like FFMS_MakeIndex except you pass it the indexer object instead of the source filename. Since you now know the track layout, you are free to pass a more restrictive track mask to index only the tracks relevant to your interests. As with FFMS_MakeIndex, all video tracks are always indexed; the trackmask only applies to audio tracks. If you change your mind and decide there are no tracks interesting to you in the file, call FFMS_CancelIndexing. Both FFMS_DoIndexing and FFMS_CancelIndexing destroys the indexer object and frees its memory.

When you have indexed the file you can write the index object to a disk file using FFMS_WriteIndex, which is useful if you expect to open the same file more than once, since it saves you from reindexing it every time. It can be particularly time-saving with very large files or files with a lot of audio tracks, since both of those can take quite some time to index.

To create an index object from a saved disk file, use FFMS_ReadIndex. Note that the index file written has an internal version number; if you have a version of FFMS2 that isn't the same as the one that created the index, it will most likely not accept the index at all (the read function will fail). If you want to verify that a given index file actually is an index of the source file you think it is, use FFMS_IndexBelongsToFile.

Function Reference

Most functions that can fail in one way or another (as well as some that should be able to but currently don't) support error reporting using the ErrorInfo parameter. Example:

char errmsg[1024];
FFMS_ErrorInfo errinfo;
errinfo.Buffer      = errmsg;
errinfo.BufferSize  = sizeof(errmsg);
errinfo.ErrorType   = FFMS_ERROR_SUCCESS;
errinfo.SubType     = FFMS_ERROR_SUCCESS;

const FFMS_Frame *frame = FFMS_GetFrame(vb, frameno, &errinfo);
/* failure? */
if (frame == NULL) {
	printf("failed to get frame number %d, error message: %s", frameno, errinfo.Buffer);
	/* etc... */
}

How many characters you want to allocate to the error message is up to you; if you allocate too few the messages may get truncated. 1024 should be enough for anyone.

FFMS_Init - initializes the library

void FFMS_Init(int CPUFeatures, int UseUTF8Paths)

Initializes the FFMS2 library. This function must be called once at the start of your program, before doing any other FFMS2 function calls.

If you are on Windows, you should also initialize COM before calling this function, since the library might have been built with HAALISOURCE. If it was indeed built with HAALISOURCE but you do not intialize COM, all MPEG-TS/PS and OGM files will cause an error when you try to open them. All other file types will work normally. Typically, you'd initialize COM something like the following:

#include <objbase.h>
/* later on, in the actual code... */
bool com_inited = false;
HRESULT res = CoInitializeEx(NULL, COINIT_MULTITHREADED);
if (SUCCEEDED(res)) 
	com_inited = true;
else if (res != RPC_E_CHANGED_MODE) {
	/* com initialization failed, handle error */
}
/* your code goes here */
/* and after you're done: */
if (com_inited)
	CoUninitialize();

Arguments

int CPUFeatures
This argument is no longer used and is left only for API/ABI compatibility. Pass 0.

int UseUTF8Paths
Controls filename handling on Windows; on all other operating systems this parameter does nothing and should be ignored.
On Windows, setting this parameter to a true value will make FFMS assume that all filename strings passed to it are UTF-8 encoded; setting it to false will make it assume filenames are in the system default codepage for non-Unicode programs. Setting this to true is one of two known ways to make FFMS2 open files with filenames containing characters that are not expressible in said codepage; the other is using the short (DOS 8.3 notation) filename. You can use the Win32 API function WideCharToMultiByte() to convert your wchar_t* Unicode strings to UTF-8 in char*, if necessary.
NOTE: setting this parameter to true will break most file open operations if you compiled FFMS in MinGW, because MinGW's std::fstream implementation doesn't support Unicode filenames.
Prior to API version 2.14.0.0 this functionality was a compile-time option and was controlled via FFMS_USE_UTF8_PATHS.

FFMS_GetLogLevel - gets FFmpeg message level

int FFMS_GetLogLevel()

Retrieves FFmpeg's current logging/message level (i.e. how much diagnostic noise it prints to STDERR). If you want to make any sense of the returned value you'd better #include <libavutil/log.h> from the FFmpeg source tree to get the relevant constant definitions. Alternatively, just copy the relevant constant definitions into your own code and hope the FFmpeg devs doesn't change them randomly for no particular reason like they do with everything else.

FFMS_SetLogLevel - sets FFmpeg message level

void FFMS_SetLogLevel(int Level)

Sets FFmpeg's logging/message level; see FFMS_GetLogLevel() for details.

FFMS_CreateVideoSource - creates a video source object

FFMS_VideoSource *FFMS_CreateVideoSource(const char *SourceFile, int Track, FFMS_Index *Index,
	int Threads, int SeekMode, FFMS_ErrorInfo *ErrorInfo)

Creates a FFMS_VideoSource object with the given properties. The FFMS_VideoSource object represents a video stream, and can be passed to other functions to retreive frames and metadata from said stream. The video stream in question must be indexed first (see the indexing functions). Note that the index object is copied into the FFMS_VideoSource object upon its creation, so once you've created the video source you can generally destroy the index object immediately, since all info you can retrieve from it is also retrievable from the FFMS_VideoSource object.

Arguments

const char *SourceFile
The source file to open. Can be an absolute or relative path.

int Track
The track number of the video track to open, as seen by the relevant demuxer. See FFMS_GetNumTracks, FFMS_GetTrackType, FFMS_GetFirstTrackOfType and their variants for further information on how to determine this.

FFMS_Index *Index
A pointer to a FFMS_Index object containing indexing information for the track you want to open.

int Threads
The number of decoding threads to use. Passing funny values like 0 or -1 may lead to undefined behavior so you better sanity check the input if you let the user set this. Values >1 have no effect if FFmpeg was not compiled with threading support.

int SeekMode
Controls how seeking (random access) is handled and hence affects frame accuracy. You will almost always want to use FFMS_SEEK_NORMAL. Has no effect on Matroska files, where the equivalent of FFMS_SEEK_NORMAL is always used. For a list of valid values, see the Constants and Preprocessor Definitions section. FFMS_SEEK_LINEAR_NO_RW may come in handy if you want to open images.

FFMS_ErrorInfo *ErrorInfo
See above.

Return values

Returns a pointer to the created FFMS_VideoSource object on success. Returns NULL and sets ErrorMsg on failure.

FFMS_CreateAudioSource - creates an audio source object

FFMS_AudioSource *FFMS_CreateAudioSource(const char *SourceFile, int Track, FFMS_Index *Index, int DelayMode,
	FFMS_ErrorInfo *ErrorInfo)

Does exactly the same thing as FFMS_CreateVideoSource, but for audio tracks. Except for DelayMode, arguments and return values are identical.

Arguments

int DelayMode

Controls how audio with a non-zero first PTS is handled; in other words what FFMS does about audio delay. Possible arguments are:

  • FFMS_DELAY_NO_SHIFT: No adjustment is made; the first decodable audio sample becomes the first sample in the output. May lead to audio/video desync.
  • FFMS_DELAY_TIME_ZERO: Samples are created (with silence) or discarded so that sample 0 in the decoded audio starts at time zero.
  • FFMS_DELAY_FIRST_VIDEO_TRACK: Samples are created (with silence) or discarded so that sample 0 in the decoded audio starts at the same time as frame 0 of the first video track. This is what most users want and is a sane default.
  • Any integer >= 0: Identical to FFMS_DELAY_FIRST_VIDEO_TRACK, but interprets the argument as a track number and adjusts the audio relative to the video track with that number (if the given track number isn't a video track, audio source creation will fail).

FFMS_DestroyVideoSource, FFMS_DestroyAudioSource - deallocates a video or audio source object

void FFMS_DestroyVideoSource(FFMS_VideoSource *V)
void FFMS_DestroyAudioSource(FFMS_AudioSource *A)

Deallocates the given FFMS_VideoSource or FFMS_AudioSource object and frees the memory allocated by FFMS_CreateVideoSource or FFMS_CreateAudioSource, respectively.

FFMS_GetVideoProperties - retrieves video properties

const FFMS_VideoProperties *FFMS_GetVideoProperties(FFMS_VideoSource *V)

Retreives the video properties from the given FFMS_VideoSource object and stores them in a FFMS_VideoProperties struct (see the Data Structures section below). Returns a pointer to said struct.

FFMS_GetAudioProperties - retrieves audio properties

const FFMS_AudioProperties *FFMS_GetAudioProperties(FFMS_AudioSource *A)

Does the exact same thing as FFMS_GetVideoProperties, but for an FFMS_AudioSource object.

FFMS_GetFrame - retrieves a given video frame

const FFMS_Frame *FFMS_GetFrame(FFMS_VideoSource *V, int n, FFMS_ErrorInfo *ErrorInfo)

Gets and decodes a video frame from the video stream represented by the given FFMS_VideoSource object and stores it in a FFMS_Frame struct. The colorspace and resolution of the frame can be changed by calling FFMS_SetOutputFormatV2 with the appropriate parameters before calling this function. Note that this function is not threadsafe (you can only request one frame at a time from a given FFMS_VideoSource object) and that the returned pointer to the FFMS_Frame is a const pointer.

Arguments

FFMS_VideoSource *V
A pointer to the FFMS_VideoSource object that represents the video stream you want to retrieve a frame from.

int n
The frame number to get. Frame numbering starts from zero, and hence the first frame is number 0 (not 1) and the last frame is number FFMS_VideoProperties->NumFrames minus 1. Requesting a frame number beyond the stream end or before the stream start (i.e. negative) may cause undefined behavior.

FFMS_ErrorInfo *ErrorInfo
See above.

Return values

Returns a pointer to the FFMS_Frame on success. Returns NULL and sets ErrorMsg on failure.

FFMS_GetFrameByTime - retrieves a video frame at a given timestamp

const FFMS_Frame *FFMS_GetFrameByTime(FFMS_VideoSource *V, double Time, FFMS_ErrorInfo *ErrorInfo)

Does the exact same thing as FFMS_GetFrame except instead of giving it a frame number you give it a timestamp in seconds, and it will retrieve the frame that starts closest to that timestamp. This function exists for the people who are too lazy to build and traverse a mapping between frame numbers and timestamps themselves.

FFMS_GetAudio - decodes a number of audio samples

int FFMS_GetAudio(FFMS_AudioSource *A, void *Buf, int64_t Start, int64_t Count, FFMS_ErrorInfo *ErrorInfo)

Decodes the requested audio samples from the audio stream represented by the given FFMS_AudioSource object and stores them in the given buffer. Note that this function is not threadsafe; you can only request one decoding operation at a time from a given FFMS_AudioSource object.

Arguments

FFMS_AudioSource *A
A pointer to the FFMS_AudioSource object that represents the audio stream you want to get samples from.

void *Buf
A pointer to the buffer where the decoded samples will end up. You are responsible for allocating and freeing this buffer yourself, so you better check the FFMS_AudioProperties for the sample format, number of channels, channel layout etc first, so you know how much memory you need to allocate. The formula to calculate the required size of the buffer is (obviously) num_bytes = bytes_per_sample * num_channels * num_samples.

int64_t Start, int64_t Count
The range of samples you want decoded. The output is Count samples long, starting from Start (inclusive). Like video frame numbers, sample numbers start from zero and hence the last sample in the stream is number FFMS_AudioProperties->NumSamples minus 1. Requesting samples beyond the stream end or before the stream start may result in undefined behavior.

FFMS_ErrorInfo *ErrorInfo
See above.

Return values

Returns 0 on success. Returns non-0 and sets ErrorMsg on failure.

FFMS_SetOutputFormatV2 - sets the output format for video frames

int FFMS_SetOutputFormatV2(FFMS_VideoSource *V, int *TargetFormats, int Width, int Height, int Resizer,
	FFMS_ErrorInfo *ErrorInfo)

Sets the colorspace and frame dimensions to be used for output of frames from the given FFMS_VideoSource by all further calls to FFMS_GetFrame and FFMS_GetFrameByTime, until next time you call FFMS_SetOutputFormatV2 or FFMS_ResetOutputFormatV. You can change the output format at any time without having to reinitialize the FFMS_VideoSource object or anything else. Can be used to convert the video to grayscale or monochrome if you are so inclined. If you provided a list of more than one colorspace/pixelformat, you should probably check the FFMS_Frame properties afterwards to see which one got selected. And remember to do so for EVERY frame or you may get a nasty surprise. Added in version 2.16.3.0 and replaces FFMS_SetOutputFormatV.

Arguments

FFMS_VideoSource *V
A pointer to the FFMS_VideoSource object that represents the video stream you want to change the output format for.

int *TargetFormats
The desired output colorspace(s). It is a -1 terminated list of acceptable output colorspace to choose from. The destination that gives the least lossy conversion from the source colorspace will automatically be selected. ON A FRAME BASIS. To get the integer constant representing a given colorspace, see FFMS_GetPixFmt.
Example:

int targetformats[3];
targetformats[0] = pixfmt1;
targetformats[1] = pixfmt2;
targetformats[2] = -1;

int Width, int Height
The desired image dimensions, in pixels. If you do not want to resize just pass the input dimensions. Passing invalid dimensions (like 0 or negative) has undefined behavior.

int Resizer
The desired image resizing algorithm, represented by an integer as enumerated in FFMS_Resizers (see the Constants and Preprocessor Definitions section). You must choose one even if you're not actually rescaling the image, because the video may change resolution mid-stream and then you will be using a resizer whether you want it or not (you will only know that the resolution changed after you actually decoded a frame with a new resolution), and it may also get used for rescaling subsampled chroma planes.

FFMS_ErrorInfo *ErrorInfo
See above.

Return values

Returns 0 on success. Returns non-0 and sets ErrorMsg on failure.

FFMS_ResetOutputFormatV - resets the video output format

void FFMS_ResetOutputFormatV(FFMS_VideoSource *V)

Resets the output format for the given FFMS_VideoSource object so that no conversion takes place. Note that the results of this function may vary wildly, particularly if the video changes resolution mid-stream. If you call it, you'd better call FFMS_GetFrame afterwards and examine the properties to see what you actually ended up with.

FFMS_SetInputFormatV - override the source format for video frames

int FFMS_SetInputFormatV(FFMS_VideoSource *V, int ColorSpace, int ColorRange, int PixelFormat,
    FFMS_ErrorInfo *ErrorInfo)

Override the source colorspace passed to SWScale for conversions and resizing for all further calls to FFMS_GetFrame and FFMS_GetFrameByTime, until next time you call FFMS_SetInputFormatV or FFMS_ResetInputFormatV. You can change the input format at any time without having to reinitialize the FFMS_VideoSource object or anything else. This is intended primarily for compatibility with programs which use the wrong YUV colorspace when converting to or from RGB, but can also be useful for files which have incorrect colorspace flags. Values passed are not checked for sanity; if you wish you may tell FFMS2 to pretend that a RGB files is actually YUV using this function, but doing so is unlikely to have useful results. This function only has an effect if the output format is also set with FFMS_SetOutputFormatV2. Added in version 2.17.1.0.

Arguments

FFMS_VideoSource *V
A pointer to the FFMS_VideoSource object that represents the video stream you want to change the input format for.

int ColorSpace
The desired input colorspace, or FFMS_CS_UNSPECIFIED to leave it unchanged.

int ColorRange
The desired input colorrange, or FFMS_CR_UNSPECIFIED to leave it unchanged.

int PixelFormat
The desired input pixel format; see FFMS_GetPixFmt. FFMS_GetPixFmt("") will leave the pixel format unchanged.

FFMS_ErrorInfo *ErrorInfo
See above.

Return values

Returns 0 on success. Returns non-0 and sets ErrorMsg on failure.

FFMS_ResetInputFormatV - resets the video input format

void FFMS_ResetInputFormatV(FFMS_VideoSource *V)

Resets the input format for the given FFMS_VideoSource object to the values specified in the source file.

FFMS_DestroyIndex - deallocates an index object

void FFMS_DestroyFFMS_Index(FFMS_Index *Index)

Deallocates the given FFMS_Index object and frees the memory that was allocated when it was created.

FFMS_GetSourceType - gets which source module was used to open the given index

int FFMS_GetSourceType(FFMS_Index *Index)

Checks which source module (libavformat, Haali's Matroska parsing library, or Haali's DirectShow splitter) was used when opening the file represented by the given FFMS_Index and returns an integer (as enumerated in FFMS_Sources; see the Constants and Preprocessor Definitions section below) that represents it.

FFMS_GetSourceTypeI - gets which source module was used to open the given indexer

int FFMS_GetSourceTypeI(FFMS_Index *Indexer)

Does the same thing as FFMS_GetSourceType, but takes an indexer instead of an index.

FFMS_GetErrorHandling - gets which error handling mode was used when creating the given index

int FFMS_GetErrorHandling(FFMS_Index *Index)

Returns the value of the ErrorHandling parameter which was passed to FFMS_DoIndexing or FFMS_MakeIndex.

FFMS_GetFirstTrackOfType - gets the track number of the first track of a given type

int FFMS_GetFirstTrackOfType(FFMS_Index *Index, int TrackType, FFMS_ErrorInfo *ErrorInfo)

Finds the first track of the given FFMS_TrackType in the given FFMS_Index and returns its track number, suitable for use as an argument to FFMS_CreateVideoSource or FFMS_CreateAudioSource, as well as to some other functions.

Arguments

FFMS_Index *Index
A pointer to the FFMS_Index object that represents the media file you want to look for tracks in.

int TrackType
The track type to look for. See FFMS_TrackType in the Constants and Preprocessor Definitions" section for valid values.

FFMS_ErrorInfo *ErrorInfo
See above.

Return values

Returns the track number (an integer greater than or equal to 0) on success. Returns a negative integer and sets ErrorMsg on failure (i.e. if no track of the given type was found).

FFMS_GetFirstIndexedTrackOfType - gets the track number of the first track of a given type

int FFMS_GetFirstIndexedTrackOfType(FFMS_Index *Index, int TrackType, FFMS_ErrorInfo *ErrorInfo)

Does the exact same thing as FFMS_GetFirstTrackOfType but ignores tracks that have not been indexed.

FFMS_GetNumTracks - gets the number of tracks in a given index

int FFMS_GetNumTracks(FFMS_Index *Index)

Returns the total number of tracks in the media file represented by the given FFMS_Index.

FFMS_GetNumTracksI - gets the number of tracks in a given indexer

int FFMS_GetNumTracksI(FFMS_Indexer *Indexer)

Returns the total number of tracks in the media file represented by the given FFMS_Indexer. In other words, does the same thing as FFMS_GetNumTracks but does not require indexing the entire file first.

FFMS_GetTrackType - gets the track type of a given track

int FFMS_GetTrackType(FFMS_Track *T)

Returns an integer representing the FFMS_TrackType (see the Constants and Preprocessor Definitions section) of the track represented by the given FFMS_Track object.

FFMS_GetTrackTypeI - gets the track type of a given track

int FFMS_GetTrackTypeI(FFMS_Indexer *Indexer, int Track)

Returns an integer representing the FFMS_TrackType (see the Constants and Preprocessor Definitions section) of the track number Track in the media file represented by the given FFMS_Indexer. In other words, does the same thing as FFMS_GetTrackType, but does not require having indexed the file first. If you have indexed the file, use FFMS_GetTrackType instead since the FFMS_Indexer object is destructed when the index is created. Note that specifying an invalid track number may lead to undefined behavior.

FFMS_GetCodecNameI - gets the name of the codec used for a given track

const char *FFMS_GetCodecNameI(FFMS_Indexer *Indexer, int Track)

Returns the human-readable name ("long name" in FFmpeg terms) of the codec used in the given track number in the media file represented by the given FFMS_Indexer object. Useful if you want to, say, pop up a menu asking the user which tracks he or she wishes to index. Note that specifying an invalid track number may lead to undefined behavior.

FFMS_GetFormatNameI - gets the name of the container format used in the given indexer

const char *FFMS_GetFormatNameI(FFMS_Indexer *Indexer)

Returns the human-readable name ("long name" in FFmpeg terms) of the container format used by the file represented by the given FFMS_Indexer.

FFMS_GetNumFrames - gets the number of frames in a given track

int FFMS_GetNumFrames(FFMS_Track *T)

Returns the number of frames in the track represented by the given FFMS_Track. For a video track this is the number of video frames, which can be useful; for an audio track it's the number of packets, which is almost never useful, since nothing in the API exposes those. A return value of 0 indicates the track has not been indexed.

FFMS_GetFrameInfo - gets information about a given frame

const FFMS_FrameInfo *FFMS_GetFrameInfo(FFMS_Track *T, int Frame)

Gets information about the given frame (identified by its frame number) from the indexing information in the given FFMS_Track and stores it in a FFMS_FrameInfo struct. See the Data Structures section below for more information. Using this function on a FFMS_Track representing a non-video track has undefined behavior.

Arguments

FFMS_Track *T
A pointer to the FFMS_Track object that represents the video track containing the frame you want to get information about.

int Frame
The frame number to get information about. See FFMS_GetFrame for information about frame numbers. Requesting information about a frame before the start or after the end of the video track may result in undefined behavior, so don't do that.

FFMS_ErrorInfo *ErrorInfo
See above.

Return values

Returns a pointer to the FFMS_FrameInfo struct on success. Returns NULL and sets ErrorMsg on failure.

FFMS_GetTrackFromIndex - retrieves track info from an index

FFMS_Track *FFMS_GetTrackFromIndex(FFMS_Index *Index, int Track)

Gets track data for the given track number from the given FFMS_Index object, stores it in a FFMS_Track object and returns a pointer to it. Use this function if you don't want to (or cannot) open the track with FFMS_CreateVideoSource or FFMS_CreateAudioSource first. If you already have a FFMS_VideoSource or FFMS_AudioSource object it's safer to use FFMS_GetTrackFromVideo or FFMS_GetTrackFromAudio (see below) instead. Note that specifying a nonexistent or invalid track number leads to undefined behavior (usually an access violation). Also note that the returned FFMS_Track object is only valid until its parent FFMS_Index object is destroyed.

Arguments

FFMS_Index *Index
A pointer to the FFMS_Index object that represents the media file containing the track whose index information you want to get.

int Track
The track number, as seen by the relevant demuxer (see FFMS_GetNumTracks, FFMS_GetTrackType, FFMS_GetFirstTrackOfType and their variants).

FFMS_ErrorInfo *ErrorInfo
See above.

Return values

Returns the FFMS_Track on success. Note that requesting indexing information for a track that has not been indexed will not cause an error, it will just return an empty FFMS_Track (check for >0 frames using FFMS_GetNumFrames to see if the returned object actually contains indexing information).

FFMS_GetTrackFromVideo, FFMS_GetTrackFromAudio - retrieves track info from audio or video source

FFMS_Track *FFMS_GetTrackFromVideo(FFMS_VideoSource *V)
FFMS_Track *FFMS_GetTrackFromAudio(FFMS_AudioSource *A)

Gets information about the track represented by the given FFMS_VideoSource or FFMS_AudioSource object and returns a pointer to a FFMS_Track object containing said information. It's generally safer to use these functions instead of FFMS_GetTrackFromIndex, since unlike that function they cannot cause access violations if you specified an nonexistent tracknumber, return a FFMS_Track that doesn't actually contain any indexing information, or return an object that ceases to be valid when the index is destroyed. Note that the returned FFMS_Track object is only valid until its parent FFMS_VideoSource or FFMS_AudioSource object is destroyed.

FFMS_GetTimeBase - retrieves the time base for the given track

const FFMS_TrackTimeBase *FFMS_GetTimeBase(FFMS_Track *T)

Finds the basic time unit for the track represented by the given FFMS_Track, stores it in a FFMS_TrackTimeBase struct and returns a pointer to said struct. See the Data Structures section for information about the time base; note that it is only meaningful for video tracks.

FFMS_WriteTimecodes - writes timecodes for the given track to disk

int FFMS_WriteTimecodes(FFMS_Track *T, const char *TimecodeFile, FFMS_ErrorInfo *ErrorInfo)

Writes Matroska v2 timecodes for the track represented by the given FFMS_Track to the given file. Only meaningful for video tracks.

Arguments

FFMS_Track *T
A pointer to the FFMS_Track object that represents the video track you want to write timecodes for.

const char *TimecodeFile
The filename to write to. Can be a relative or absolute path. The file will be truncated and overwritten if it already exists.

FFMS_ErrorInfo *ErrorInfo
See above.

Return values

Returns 0 on success. Returns non-0 and sets ErrorMsg on failure.

FFMS_MakeIndex - indexes a given source file

FFMS_Index *FFMS_MakeIndex(const char *SourceFile, int IndexMask, int DumpMask,
	TAudioNameCallback ANC, void *ANCPrivate, int ErrorHandling,
	TIndexCallback IC, void *ICPrivate, FFMS_ErrorInfo *ErrorInfo);

Indexes all video tracks and the given audio tracks in the given media file and returns a FFMS_Index object representing the file in question. Can also decode and write audio tracks to Wave64 files on disk while indexing.

Arguments

const char *SourceFile
The filename of the media file to index. Can be a relative or absolute path.

int IndexMask, int DumpMask
Binary masks of the track numbers of the audio tracks to index and decode to disk, respectively. Pass 0 to index/decode no audio tracks, or -1 to index/decode all. Decoding a track means it will automatically be indexed regardless of what the IndexMask says, but indexing a track does not automatically mean that it will be decoded.

TAudioNameCallback ANC
A function pointer to a callback function that will generate the filename(s) for the dumped audio tracks. To get the default filename(s), pass &FFMS_DefaultAudioFilename. See Callbacks below for details if you want to write your own function. If the DumpMask is 0, you may pass NULL here.

void *ANCPrivate
A pointer of your choice that will be passed as an argument to the audio filename generation callback function. See Callbacks below for details. If DumpMask is 0, you may pass NULL here. If you are using FFMS_DefaultAudioFilename, you must pass a format string here. See the Audio Filename Format Strings section for details.

int ErrorHandling
Depending on the setting audio decoding errors will have different results. Use the FFMS_IEH_* constants to select the between the possible behaviors. FFMS_IEH_STOP_TRACK should be the best default to just make it work. Has no effect if the DumpMask is non-zero, in which case audio decoding errors will always cause the indexing to fail.

TIndexCallback IC
A function pointer to a callback function that can be used to update progress. See Callbacks below for details.

void *ICPrivate
A pointer of your choice that will be passed as an argument to the progress reporting callback function. See Callbacks below for details.

FFMS_ErrorInfo *ErrorInfo
See above.

Callbacks

This function has two potential callbacks. One can, if you so desire, call your code back intermittently so you can see how the indexing is progressing. This is accomplished using a function pointer to a function with the following signature: 

int FFMS_CC FunctionName(int64_t Current, int64_t Total, void *ICPrivate)

The callback function's arguments are as follows:

  • int64_t Current, int64_t Total - The indexing progress (amount done/total amount).
  • void *Private - the same pointer as the one you passed as the Private argument to FFMS_MakeIndex. Can be used for anything you like, but one example (in a GUI program) is to use it for passing a progress ticker object that you can update with each call to the indexing function.

Return 0 from the callback function to continue indexing, non-0 to cancel indexing (returning non-0 will make FFMS_MakeIndex fail with the reason "indexing cancelled by user").

The other callback is used to generate the filename(s) of the audio file(s) written if DumpMask is non-zero. It has the following signature: 

int FFMS_CC FunctionName(const char *SourceFile, int Track, const FFMS_AudioProperties *AP,
	char *FileName, int FNSize, void *Private)

The callback function is called twice for each audio file generated. The first time FileName is NULL, and you should return the number of characters your generated filename will use plus one, and do nothing else. The second time FileName is a pointer to a pre-allocated array of char; you should write your generated filename to that and return the number of characters actually written plus one. Generally the easiest way to do this in both cases is to use snprintf. See the implementation of GenAudioFilename in ffmsindex.cpp for an example on how to do it.
The callback function's arguments are as follows:

  • const char *SourceFile - The name of the source media file.
  • int Track - The track number of the audio track being dumped.
  • const FFMS_AudioProperties *AP - A pointer to the FFMS_AudioProperties struct containing information about the audio track being dumped. Note that the LastTime field is not defined since the last timestamp has not yet been encountered during indexing.
  • char *FileName - A pointer to the string to which the callback function should write the generated filename (see above).
  • int FNSize - The length of the FileName string.
  • void *Private - The ANCPrivate pointer passed to FFMS_MakeIndex. Can be used to store data between calls, or to give audio tracks individual names that aren't just based on their properties.

Most of the parameters may seem pointless since you don't need to use them, but they are passed so that you can easily generate a filename based on the audio track's properties if you want to.

Return values

Returns a pointer to the created FFMS_Index on success. Returns NULL and sets ErrorMsg on failure.

FFMS_DefaultAudioFilename - default callback for audio filename generation

This function generates a default audio filename for use when dumping audio tracks to disk as Wave64 files during indexing. Its only use in the public API is as a default callback for FFMS_MakeIndex and FFMS_DoIndexing; you should never call it directly. See FFMS_MakeIndex for a description of its arguments.

FFMS_CreateIndexer - creates an indexer object for the given file

FFMS_Indexer *FFMS_CreateIndexer(const char *SourceFile, FFMS_ErrorInfo *ErrorInfo)

Creates a FFMS_Indexer object for the given SourceFile and returns a pointer to it. See Indexing and You for details on how to use the indexer. Is basically a shorthand for FFMS_CreateIndexerWithDemuxer(SourceFile, FFMS_SOURCE_DEFAULT, ErrorInfo).

Return values

Returns a pointer to the FFMS_Indexer on success. Returns NULL and sets ErrorMsg on failure.

FFMS_CreateIndexerWithDemuxer - creates an indexer object for the given file, using the given source module

FFMS_Indexer *FFMS_CreateIndexer(const char *SourceFile, int Demuxer, FFMS_ErrorInfo *ErrorInfo)

Creates a FFMS_Indexer object for the given SourceFile using the given Demuxer (as enumerated in FFMS_Sources) and returns a pointer to it. See Indexing and You for details on how to use the indexer.
The chosen demuxer gets used for both indexing and decoding later on. Only force one if you know what you're doing. Picking a demuxer that doesn't work on your file will not cause automatic fallback on lavf or automatic probing; it'll just cause indexer creation to fail.

Return values

Returns a pointer to the FFMS_Indexer on success. Returns NULL and sets ErrorMsg on failure.

FFMS_DoIndexing - indexes the file represented by an indexer object

FFMS_Index *FFMS_DoIndexing(FFMS_Indexer *Indexer, int IndexMask, int DumpMask,
	TAudioNameCallback ANC, void *ANCPrivate, int ErrorHandling, TIndexCallback IC, void *ICPrivate,
	FFMS_ErrorInfo *ErrorInfo)

Does the exact same thing as FFMS_MakeIndex, but takes an indexer object instead of a source filename. Return values and arguments are identical to FFMS_MakeIndex; see that function for details. See the Indexing and You section for more details about indexing. Note that calling this function destroys the FFMS_Indexer object and frees the memory allocated by FFMS_CreateIndexer (even if indexing fails for any reason).

FFMS_CancelIndexing - destroys the given indexer object

void FFMS_CancelIndexing(FFMS_Indexer *Indexer)

Destroys the given FFMS_Indexer object and frees the memory allocated by FFMS_CreateIndexer.

FFMS_ReadIndex - reads an index file from disk

FFMS_Index *FFMS_ReadIndex(const char *IndexFile, FFMS_ErrorInfo *ErrorInfo)

Attempts to read indexing information from the given IndexFile, which can be an absolute or relative path. Returns the FFMS_Index on success; returns NULL and sets ErrorMsg on failure.

FFMS_IndexBelongsToFile - check if a given index belongs to a given file

int FFMS_IndexBelongsToFile(FFMS_Index *Index, const char *SourceFile, FFMS_ErrorInfo *ErrorInfo)

Makes a heuristic (but very reliable) guess about whether the given FFMS_Index is an index of the given SourceFile or not. Useful to determine if the index object you just read with FFMS_ReadIndex is actually relevant to your interests, since the only two ways to pair up index files with source files are a) trust the user blindly, or b) comparing the filenames; neither is very reliable.

Arguments

FFMS_Index *Index
The index object to check.

const char *SourceFile
The source file to verify the index against.

Return values

Returns 0 if the given index is determined to belong to the given file. Returns non-0 and sets ErrorMsg otherwise.

FFMS_WriteIndex - writes an index object to disk

int FFMS_WriteIndex(const char *IndexFile, FFMS_Index *TrackIndices, FFMS_ErrorInfo *ErrorInfo)

Writes the indexing information from the given FFMS_Index to the given IndexFile (which can be an absolute or relative path; it will be truncated and overwritten if it already exists). Returns 0 on success; returns non-0 and sets ErrorMsg on failure.

FFMS_GetPixFmt - gets a colorspace identifier from a colorspace name

int FFMS_GetPixFmt(const char *Name)

Translates a given colorspace/pixel format Name to an integer constant representing it, suitable for passing to FFMS_SetOutputFormatV2 (after some manipulation, see that function for details). This function exists so that you don't have to include a FFmpeg header file in every single program you ever write. For a list of colorspaces and their names, see libavutil/pixfmt.h. To get the name of a colorspace, strip the leading PIX_FMT_ and convert the remainder to lowercase. For example, the name of PIX_FMT_YUV420P is yuv420p. It is strongly recommended to use this function instead of including pixfmt.h directly, since this function guarantees that you will always get the constant definitions from the version of FFmpeg that FFMS2 was linked against.

Arguments

const char *Name
The name of the desired colorspace/pixel format, as a nul-terminated ASCII string.

Return values

Returns the integer constant representing the given colorspace/pixel format on success. Returns the integer constant representing PIX_FMT_NONE (that is, -1) on failure (i.e. if no matching colorspace was found), but note that you can call FFMS_GetPixFmt("none") and get the same return value without it being a failed call, strictly speaking.

FFMS_GetPresentSources - checks what source modules the library was compiled with

int FFMS_GetPresentSources()

Checks which source modules the library was compiled with and returns an integer by binary OR'ing the relevant constants from FFMS_Sources together.

FFMS_GetEnabledSources - checks what source modules are actually available for use

int FFMS_GetEnabledSources()

Does the same thing as FFMS_GetPresentSources but checks what source modules are actually available for use instead of which ones are compiled in.

FFMS_GetVersion - returns FFMS_VERSION constant

int FFMS_GetVersion()

Returns the FFMS_VERSION constant as defined in ffms.h as an integer.

Data Structures

The following public data structures may be of interest.

FFMS_Frame

typedef struct {
    uint8_t *Data[4];
    int Linesize[4];
    int EncodedWidth;
    int EncodedHeight;
    int EncodedPixelFormat;
    int ScaledWidth;
    int ScaledHeight;
    int ConvertedPixelFormat;
    int KeyFrame;
    int RepeatPict;
    int InterlacedFrame;
    int TopFieldFirst;
    char PictType;
    int ColorSpace;
    int ColorRange;
} FFMS_Frame;

A struct representing a video frame. The fields are:

  • uint8_t *Data[4] - An array of pointers to the picture planes (fields containing actual pixel data). Planar formats use more than one plane, for example YV12 uses one plane each for the Y, U and V data. Packed formats (such as the various RGB32 flavors) use only the first plane. If you want to determine if plane i contains data or not, check for FFMS_Frame->Linesize[i] > 0.
  • int Linesize[4] - An array of integers representing the length of each scan line in each of the four picture planes, in bytes. In alternative terminology, this is the "pitch" of the plane. Usually, the total size in bytes of picture plane i is FFMS_Frame->Linesize[i] * FFMS_VideoProperties->Height, but do note that some pixel formats (most notably YV12) has vertical chroma subsampling, and then the U/V planes may be of a different height than the primary plane.
  • int EncodedWidth; int EncodedHeight - The original resolution of the frame (in pixels), as encoded in the compressed file, before any scaling was applied. Note that must not necessarily be the same for all frames in a stream.
  • int EncodedPixelFormat - The original pixel format of the frame, as encoded in the compressed file.
  • int ScaledWidth; int ScaledHeight; - The output resolution of the frame (in pixels), i.e. the resolution of what is actually stored in the Data field. Same as FFMS_VideoProperties->Width/Height, but unlike that struct, this one gets updated automatically when you call FFMS_GetFrame, so you don't have to call FFMS_GetVideoProperties all the time to see if someone changed the output format while you weren't looking.
  • int ConvertedPixelFormat - The output pixel format of the frame, i.e. the pixel format of what is actually stored in the Data field.
  • int KeyFrame - Nonzero if the frame is a keyframe, 0 otherwise.
  • int RepeatPict - An integer repesenting the RFF flag for this frame; i.e. the frame shall be displayed for 1+RepeatPict time units, where the time units are expressed in the special RFF timebase available in FFMS_VideoProperties->RFFDenominator and FFMS_VideoProperties->RFFNumerator. Note that if you actually end up using this, you need to ignore the usual timestamps (calculated via the FFMS_TrackTimeBase and the frame PTS) since they are fundamentally incompatible with RFF flags.
  • int InterlacedFrame - Nonzero if the frame was coded as interlaced, zero otherwise.
  • int TopFieldFirst - Nonzero if the frame has the top field first, zero if it has the bottom field first. Only relevant if InterlacedFrame is nonzero.
  • char PictType - A single character denoting coding type (I/B/P etc) of the compressed frame. See the Constants and Preprocessor Definitions section for more information about what the different letters mean.
  • int ColorSpace - Identifies the YUV color coefficients used in the frame. Same as in the MPEG-2 specs; see the FFMS_ColorSpaces enum.
  • int ColorRange - Identifies the luma range of the frame. See the FFMS_ColorRanges enum.

FFMS_TrackTimeBase

typedef struct {
    int64_t Num;
    int64_t Den;
} FFMS_TrackTimeBase;

A struct representing the basic time unit of a track, as a rational number where Num is the numerator and Den is the denominator. Note that while this rational number may occasionally turn out to be equal to 1/framerate for some CFR video tracks, it really has no relation whatsoever with the video framerate and you should definitely not assume anything framerate-related based on it.

FFMS_FrameInfo

typedef struct {
    int64_t PTS;
    int RepeatPict;
    int KeyFrame;
} FFMS_FrameInfo;

A struct representing basic metadata about a given video frame. The fields are:

  • int64_t PTS - The decoding timestamp of the frame. To convert this to a timestamp in wallclock milliseconds, use the relation int64_t timestamp = (int64_t)((FFMS_FrameInfo->PTS * FFMS_TrackTimeBase->Num) / (double)FFMS_TrackTimeBase->Den).
  • int RepeatPict - RFF flag for the frame; same as in FFMS_Frame, see that structure for an explanation.
  • int KeyFrame - Non-zero if the frame is a keyframe, zero otherwise.

FFMS_VideoProperties

typedef struct {
    int FPSDenominator;
    int FPSNumerator;
    int RFFDenominator;
    int RFFNumerator;
    int NumFrames;
    int SARNum;
    int SARDen;
    int CropTop;
    int CropBottom;
    int CropLeft;
    int CropRight;
    int TopFieldFirst;
    int ColorSpace; [DEPRECATED]
    int ColorRange; [DEPRECATED]
    double FirstTime;
    double LastTime;
} FFMS_VideoProperties;

A struct containing metadata about a video track. The fields are:

  • int FPSDenominator; int FPSNumerator; - The nominal framerate of the track, as a rational number. For Matroska files, this number is based on the average frame duration of all frames, while for everything else it's based on the duration of the first frame. While it might seem tempting to use these values to extrapolate wallclock timestamps for each frame, you really shouldn't do that since it makes your code unable to handle variable framerate properly. The ugly reality is that these values are pretty much only useful for informational purposes; they are only somewhat reliable for antiquated containers like AVI. Normally they should never be used for practical purposes; generate individual frame timestamps from FFMS_FrameInfo->PTS instead.
  • int RFFDenominator; int RFFNumerator; - The special RFF timebase, as a rational number. See RepeatPict in the FFMS_Frame documentation for more information.
  • int NumFrames; - The number of frames in the video track.
  • int SARNum; int SARDen; - The sample aspect ratio of the video frames, as a rational number where SARNum is the numerator and SARDen is the denominator. Note that this is a metadata setting that you are free to ignore, but if you want the proper display aspect ratio with anamorphic material, you should honor it. On the other hand, there are situations (like when encoding) where you should probably ignore it because the user expects it to be ignored.
  • int CropTop; int CropBottom; int CropLeft; int CropRight; - The number of pixels in each direction you should crop the frame before displaying it. Note that like the SAR, this is a metadata setting and you are free to ignore it, but if you want things to display 100% correctly you should honor it.
  • int TopFieldFirst - Nonzero if the stream has the top field first, zero if it has the bottom field first.
  • int ColorSpace - Identifies the YUV color coefficients used in the stream. Same as in the MPEG-2 specs; see the FFMS_ColorSpaces enum. The ColorSpace property in FFMS_Frame should be instead of this, as this can vary between frames.
  • int ColorRange - Identifies the luma range of the stream. See the FFMS_ColorRanges enum. The ColorRange property in FFMS_Frame should be instead of this, as this can vary between frames.
  • double FirstTime; double LastTime; - The first and last timestamp of the stream respectively, in seconds. Useful if you want to know if the stream has a delay, or for quickly determining its length in seconds.

FFMS_AudioProperties

typedef struct {
    int SampleFormat;
    int SampleRate;
    int BitsPerSample;
    int Channels;
    int64_t ChannelLayout;
    int64_t NumSamples;
    double FirstTime;
    double LastTime;
} FFMS_AudioProperties;

A struct containing metadata about an audio track. The fields are:

  • int SampleFormat - An integer that represents the audio sample format. See FFMS_SampleFormat in the Constants and Preprocessor Definitions section.
  • int SampleRate - The audio samplerate, in samples per second.
  • int BitsPerSample - The number of bits per audio sample. Note that this signifies the number of bits actually used to code each sample, not the number of bits used to store each sample, and may hence be different from what the SampleFormat would imply. Figuring out which bytes are significant and which aren't is left as an exercise for the reader.
  • int Channels - The number of audio channels.
  • int64_t ChannelLayout - The channel layout of the audio stream. Constructed by binary OR'ing the relevant integers from FFMS_AudioChannel together, which means that if the audio has the channel FFMS_CH_EXAMPLE, the operation (ChannelOrder & FFMS_CH_EXAMPLE) will evaluate to true. The samples are interleaved in the order the channels are listed in the FFMS_AudioChannel enum; see that part of the Constants and Preprocessor Definitions sections for more details.
  • int64_t NumSamples - The number of samples in the audio track.
  • double FirstTime; double LastTime; - The first and last timestamp of the stream respectively, in milliseconds. Useful if you want to know if the stream has a delay, or for quickly determining its length in seconds.

Constants and Preprocessor Definitions

The following constants and preprocessor definititions defined in ffms.h are suitable for public usage.

FFMS_Errors

enum FFMS_Errors {
    // No error
    FFMS_ERROR_SUCCESS = 0,

    // Main types - where the error occurred
    FFMS_ERROR_INDEX = 1,           // index file handling

    FFMS_ERROR_WAVE_WRITER,         // WAVE64 file writer
    FFMS_ERROR_CANCELLED,           // operation aborted

    // Subtypes - what caused the error
    FFMS_ERROR_UNKNOWN = 20,        // unknown error
    FFMS_ERROR_UNSUPPORTED,         // format or operation is not supported with this binary
    FFMS_ERROR_FILE_READ,           // cannot read from file
    FFMS_ERROR_FILE_WRITE,          // cannot write to file
    FFMS_ERROR_NO_FILE,             // no such file or directory
    FFMS_ERROR_VERSION,             // wrong version
    FFMS_ERROR_ALLOCATION_FAILED,   // out of memory
    FFMS_ERROR_INVALID_ARGUMENT,    // invalid or nonsensical argument
    FFMS_ERROR_CODEC,               // decoder error
    FFMS_ERROR_NOT_AVAILABLE,       // requested mode or operation unavailable in this binary
    FFMS_ERROR_FILE_MISMATCH,       // provided index does not match the file
    FFMS_ERROR_USER                 // problem exists between keyboard and chair
};

Used to identify errors. Should be self-explanatory.

FFMS_Sources

enum FFMS_Sources {
    FFMS_SOURCE_DEFAULT     = 0x00,
    FFMS_SOURCE_LAVF        = 0x01,
    FFMS_SOURCE_MATROSKA    = 0x02,
    FFMS_SOURCE_HAALIMPEG   = 0x04,
    FFMS_SOURCE_HAALIOGG    = 0x08
};

Identifies source modules.

  • FFMS_SOURCE_LAVF - libavformat (Libav/FFmpeg)
  • FFMS_SOURCE_MATROSKA - Haali's BSD-licensed native Matroska parsing library
  • FFMS_SOURCE_HAALIMPEG - Haali's closed-source DirectShow splitter (MPEG TS/PS)
  • FFMS_SOURCE_HAALIOGG - Haali's closed-source DirectShow splitter (Ogg/OGM)

FFMS_CPUFeatures

enum FFMS_CPUFeatures {
    FFMS_CPU_CAPS_MMX       = 0x01,
    FFMS_CPU_CAPS_MMX2      = 0x02,
    FFMS_CPU_CAPS_3DNOW     = 0x04,
    FFMS_CPU_CAPS_ALTIVEC   = 0x08,
    FFMS_CPU_CAPS_BFIN      = 0x10,
    FFMS_CPU_CAPS_SSE2      = 0x20
};

No longer used by anything in FFMS2. This enumeration will go away at some point in the future.

FFMS_SeekMode

enum FFMS_SeekMode {
    FFMS_SEEK_LINEAR_NO_RW  = -1,
    FFMS_SEEK_LINEAR        = 0,
    FFMS_SEEK_NORMAL        = 1,
    FFMS_SEEK_UNSAFE        = 2,
    FFMS_SEEK_AGGRESSIVE    = 3
};

Used in FFMS_CreateVideoSource to control the way seeking is handled. Explanation of the values:

  • FFMS_SEEK_LINEAR_NO_RW - Linear access without rewind; i.e. will throw an error if each successive requested frame number isn't bigger than the last one. Only intended for opening images but might work on well with some obscure video format.
  • FFMS_SEEK_LINEAR - Linear access (i.e. if you request frame n without having requested frames 0 to n-1 in order first, all frames from 0 to n will have to be decoded before n can be delivered). The definition of slow, but should make some formats "usable".
  • FFMS_SEEK_NORMAL - Safe normal. Bases seeking decisions on the keyframe positions reported by libavformat.
  • FFMS_SEEK_UNSAFE - Unsafe normal. Same as FFMS_SEEK_NORMAL but no error will be thrown if the exact destination has to be guessed.
  • FFMS_SEEK_AGGRESSIVE - Aggressive. Seeks in the forward direction even if no closer keyframe is known to exist. Only useful for testing and containers where libavformat doesn't report keyframes properly.

FFMS_IndexErrorHandling

enum FFMS_IndexErrorHandling {
    FFMS_IEH_ABORT = 0,
    FFMS_IEH_CLEAR_TRACK = 1,
    FFMS_IEH_STOP_TRACK = 2,
    FFMS_IEH_IGNORE = 3
};

Used by the indexing functions to control behavior when a decoding error is encountered.

  • FFMS_IEH_ABORT - abort indexing and raise an error
  • FFMS_IEH_CLEAR_TRACK - clear all indexing entries for the track (i.e. return a blank track)
  • FFMS_IEH_STOP_TRACK - stop indexing but keep previous indexing entries (i.e. return a track that stops where the error occurred)
  • FFMS_IEH_IGNORE - ignore the error and pretend it's raining

enum FFMS_TrackType {
    FFMS_TYPE_UNKNOWN = -1,
    FFMS_TYPE_VIDEO,
    FFMS_TYPE_AUDIO,
    FFMS_TYPE_DATA,
    FFMS_TYPE_SUBTITLE,
    FFMS_TYPE_ATTACHMENT
};

Used for determining the type of a given track. Note that there are currently no functions to handle any type of track other than FFMS_TYPE_VIDEO and FFMS_TYPE_AUDIO. See FFMS_GetTrackType, FFMS_GetFirstTrackOfType and their variants.

FFMS_SampleFormat

enum FFMS_SampleFormat {
    FFMS_FMT_U8 = 0,
    FFMS_FMT_S16,
    FFMS_FMT_S32,
    FFMS_FMT_FLT,
    FFMS_FMT_DBL
};

  • FFMS_FMT_U8 - One 8-bit unsigned integer (uint8_t) per sample.
  • FFMS_FMT_S16 - One 16-bit signed integer (int16_t) per sample.
  • FFMS_FMT_S32 - One 32-bit signed integer (int32_t) per sample.

    FFMS_CH_FRONT_LEFT              = 0x00000001,
    FFMS_CH_FRONT_RIGHT             = 0x00000002,
    FFMS_CH_FRONT_CENTER            = 0x00000004,

    FFMS_CH_STEREO_RIGHT            = 0x40000000
};

Describes the audio channel layout of an audio stream. The names should be self-explanatory.
As you might have noticed, these constants are the same as the ones used for the dwChannelMask property of Microsoft's WAVEFORMATEXTENSIBLE struct; see its MSDN documentation page for more information.
The exceptions to this convenient compatibility are FFMS_CH_STEREO_LEFT and FFMS_CH_STEREO_RIGHT, which are FFmpeg extensions.

    FFMS_RESIZER_SPLINE         = 0x400
};

Describes various image resizing algorithms, as used in the arguments to FFMS_SetOutputFormatV2. The names should be self-explanatory.

FFMS_AudioDelayModes

enum FFMS_AudioDelayModes {
    FFMS_DELAY_NO_SHIFT           = -3,
    FFMS_DELAY_TIME_ZERO          = -2,
    FFMS_DELAY_FIRST_VIDEO_TRACK  = -1
};

Describes the different audio delay handling modes. See FFMS_CreateAudioSource for a detailed explanation.

FFMS_ColorSpaces

enum FFMS_ColorSpaces {
    FFMS_CS_RGB         = 0,
    FFMS_CS_BT709       = 1,
    FFMS_CS_UNSPECIFIED = 2,
    FFMS_CS_FCC         = 4,
    FFMS_CS_BT470BG     = 5,
    FFMS_CS_SMPTE170M   = 6,
    FFMS_CS_SMPTE240M   = 7,
};

Identifies the color coefficients used for a YUV stream. The numerical constants are the same as in the MPEG-2 specification.
Some of these are specified or aliased in a number of places. Most importantly:
"BT709" (ITU-T Rec. 709) is equivalent to ITU-R BT1361, IEC 61966-2-4 xvYCC709 and SMPTE RP177 Annex B;
"BT470BG" (ITU-R BT. 470, also known as ITU-T Rec. 601) is equivalent to ITU-R BT601-6 625, ITU-R BT1358 625, ITU-R BT1700 625 PAL & SECAM and IEC 61966-2-4 xvYCC601;
"SMPTE170M" (SMPTE standard 170 M) is functionally the same as BT470BG, and is furthermore equivalent to ITU-R BT601-6 525, ITU-R BT1358 525, and ITU-R BT1700 NTSC.

FFMS_ColorRanges

enum FFMS_ColorRanges {
    FFMS_CR_UNSPECIFIED = 0,
    FFMS_CR_MPEG        = 1,
    FFMS_CR_JPEG        = 2,
};

Identifies the valid range of luma values in a YUV stream. FFMS_CR_MPEG is the standard "TV range" with head- and footroom. That is, valid luma values range from 16 to 235 with 8-bit color. FFMS_CR_JPEG is "full range"; all representable luma values are valid.

FFMS_CC

#ifdef _WIN32
#   define FFMS_CC __stdcall
#else
#   define FFMS_CC
#endif

The calling convention used by FFMS2 API functions and callbacks. Defined to __stdcall if _WIN32 is defined. Otherwise defined, but not used.

FFmpegSource2 User Manual

Opens files using FFmpeg and (almost) nothing else. May be frame accurate on good days. The source is MIT licensed and can be obtained from http://code.google.com/p/ffmpegsource/source/checkout. The precompiled binary is GPL3 licensed. If you are religious you may consider this the second coming.

Donate if you like this software. Collecting weird clips from the internet and making them play takes more time than you'd think.

Limitations

  • Requires Haali's Media Splitter if you want to seek in OGM or MPEG PS/TS. Trying to do non-linear access in those containers without it will end in tears.
  • Haali's splitter requires transport streams to be cut at packet boundaries. Use TsRemux to fix the stream if you get an error message complaining about this.
  • Because of LAVF's demuxer, most raw streams (such as elementary h264 and other mpeg video streams) will fail to work properly.
  • FFAudioSource() will have to remake any index implicitly created by FFVideoSource() and therefore code like 
    AudioDub(FFVideoSource(X), FFAudioSource(X))
    will require two indexing passes. Apart from the time consumed this is harmless. To work around it open the audio first: 
    A = FFAudioSource(X)
V = FFVideoSource(X)
AudioDub(V, A)
    or use FFIndex(), like so: 
    FFIndex(X)
AudioDub(FFVideoSource(X), FFAudioSource(X))

Known issues

  • Interlaced H.264 is decoded in an odd way; each field gets its own full-height frame and the fieldrate is reported as the framerate, and furthermore one of the fields (odd or even) may "jump around". To get the correct behavior, you can try setting fpsnum and fpsden so that the framerate is halved (may or may not work). This issue is caused by libavcodec.
  • Decoding some M2TS files using Haali's splitter will cause massive blocking and other corruption issues. You can work around the issue either by remuxing the file to MKV (using GDSMux (make sure you untick "minimize output file size" in the Global settings tab) or eac3to), or (if you will be doing linear decoding only) by setting demuxer="lavf" in FFIndex and using seekmode=0 with FFVideoSource. The cause of this issue is unknown but being investigated.

Compatibility

Video

  • AVI, MKV, MP4, FLV: Frame accurate
  • WMV: Frame accurate(?) but avformat seems to pick keyframes relatively far away
  • OGM: Frame accurate(?)
  • VOB, MPG: Seeking seems to be off by one or two frames now and then
  • M2TS, TS: Seeking seems to be off a few frames here and there
  • Image files: Most formats can be opened if seekmode=-1 is set, no animation support

Audio

Seeking should be sample-accurate with most codecs in AVI, MKV, MP4 and FLV with two notable exceptions, namely MP3 and AC3 where FFmpeg's decoders seem to be completely broken (with MP3 in particular you can feed the decoder the same encoded data three times in a row and get a different decoded result every time). Still, results should usually be "good enough" for most purposes.

Decoding linearly will almost always work correctly.

Indexing and You

Before FFMS2 can open a file, it must be indexed first so that keyframe/sample positions are known and seeking is easily accomplished. This is done automatically when using FFVideoSource() or FFAudioSource(), but if you want to you can invoke the indexing yourself by calling FFIndex(), or by running ffmsindex.exe. By default the index is written to a file so it can be reused the next time you open the same file, but this behavior can be turned off if desired.

If you wonder why FFMS2 takes so long opening files, the indexing is the answer. If you want a progress report on the indexing, you can use the supplied ffmsindex.exe commandline program.

Function reference

FFIndex

FFIndex(string source, string cachefile = source + ".ffindex", int indexmask = -1,
    int dumpmask = 0, string audiofile = "%sourcefile%.%trackzn%.w64", int errorhandling = 3,
    bool overwrite = false, bool utf8 = false, string demuxer = "default")

Indexes a number of tracks in a given source file and writes the index file to disk, where it can be picked up and used by FFVideoSource or FFAudioSource. Normally you do not need to call this function manually; it's invoked automatically if necessary by FFVideoSource/FFAudioSource. It does, however, give you more control over how indexing is done and it can also dump audio tracks to WAVE64 files while indexing is in progress.

Note that this function returns an integer, not a clip (since it doesn't open video, nor audio). The return value isn't particularly interesting, but for the record it's 0 if the index file already exists (and is valid) and overwrite was not enabled, 1 if the index file was created and no previous index existed, and 2 if the index file was created by overwriting an existing, valid index file.

Arguments

string source
The source file to index.
string cachefile = source + ".ffindex"
The filename of the index file (where the indexing data is saved). Defaults to sourcefilename.ffindex.
int indexmask = -1
A binary mask representing what audio tracks should be indexed (all video tracks are always indexed; you have no choice in the matter). The mask is constructed by bitshifting 1 left by the track number; if multiple tracks are desired, bitwise OR each value so created together to get the full mask. In other words, the mask is a bit field where each bit is a track number (the least significant bit is track number 0). Since Avisynth doesn't have any bitwise operators at all, constructing a mask for more than one track inside an Avisynth script is a rather annoying task; for a single track the mask is, naturally, 2 to the power of the track number minus 1 (i.e. if you want to index track 3, the mask is 2^(3-1) = 4).
Since the mask works like it does, and FFMS2 is designed to run on a machine that uses two's complement integers, -1 (the default) means index all tracks and 0 means index none.
Note that FFMS2's idea about what track has what number may be completely different from what any other application might think, and that track numbering starts from 1.
int dumpmask = 0
The same as indexmask, but the tracks flagged by this mask are dumped to disk as decompressed Wave64 files. This mask overrides indexmask if set to nonzero (more specifically, they are bitwise OR'ed together), since dumping a track indexes it at the same time.
string audiofile = "%sourcefile%.%trackzn%.w64"
A string representing a filename template that determines where the audio tracks set to be dumped by the dumpmask will be written. You can use a number of variables here; make sure you include a track number variable if you're dumping multiple tracks, or you'll get really weird results when FFMS2 tries to write multiple tracks to the same file. Available variables:
  • %sourcefile% - same as the source argument, i.e. the file the audio is decoded from
  • %trackn% - the track number
  • %trackzn% - the track number, zero padded to two digits
  • %samplerate% - sample rate in Hertz
  • %channels% - number of channels
  • %bps% - bits per sample
  • %delay% - delay, or more exactly the first timestamp encountered in the audio stream
int errorhandling = 3
Controls what happens if an audio decoding error is encountered during indexing. Possible values are:
  • 0: Raise an error and abort indexing. No index file is written.
  • 1: Clear the affected track (effectively making it silent) and continue.
  • 2: Stop indexing the track but keep all the index entries so far, effectively ending the track where the error occured.
  • 3: Pretend it's raining and continue anyway. This is the default; if you encounter odd noises in the audio, try mode 0 instead and see if it's FFMS2's fault.
bool overwrite = false
If set to true, FFIndex() will reindex the source file and overwrite the index file even if the index file already exists and is valid. Mostly useful for trackmask changes and testing.
bool utf8 = false
If set to true, FFMS will assume that the .avs script is encoded as UTF-8 and therefore interpret all filenames as UTF-8 encoded strings. This makes it possible to open files with funny filenames that otherwise would not be openable. You only need to set this parameter on the first FFMS2 function you call in a script; subsequent uses will have no further effect.
NOTE: You must make sure you save the file without a BOM (byte-order marker) or Avisynth will refuse to open it. Notepad will write a BOM, so use something else.
You should also note that setting this parameter incorrectly will cause all file openings to fail unless your filenames are exclusively 7-bit ASCII compatible.
string demuxer = "default"
Forces FFMS to use a given demuxer, namely one of:
  • default: probe for the best source module, i.e. choose automatically. This is the default (duh).
  • lavf: use libavformat.
  • matroska: use Haali's Matroska parser. Obviously only works for Matroska and WebM files.
  • haalimpeg: use Haali's DirectShow MPEG TS/PS parser. Only works if Haali Media Splitter is installed and only on MPEG TS/PS files (.ts/.m2ts/.mpg/.mpeg).
  • haaliogg: use Haali's DirectShow Ogg parser. As above, only works if Haali Media Splitter is installed, and only on Ogg files (.ogg/.ogm).
You should only use this parameter if you know exactly what you're doing and exactly why you want to force another demuxer.

FFVideoSource

FFVideoSource(string source, int track = -1, bool cache = true,
    string cachefile = source + ".ffindex", int fpsnum = -1, int fpsden = 1,
    int threads = -1, string timecodes = "", int seekmode = 1, int rffmode = 0,
    int width = -1, int height = -1, string resizer = "BICUBIC",
    string colorspace = "", bool utf8 = false, string varprefix = "")

Opens video. Will invoke indexing of all video tracks (but no audio tracks) if no valid index file is found.

Arguments

string source
The source file to open.
int track = -1
The video track number to open, as seen by the relevant demuxer. Track numbers start from zero, and are guaranteed to be countinous (i.e. there must be a track 1 if there is a track 0 and a track 2). -1 means open the first video track. Note that FFMS2's idea about what track has what number may (or may not) be completely different from what some other application might think. Trying to open an audio track with FFVideoSource will naturally fail.
bool cache = true
If set to true (the default), FFVideoSource will first check if the cachefile contains a valid index, and if it does, that index will be used. If no index is found, all video tracks will be indexed, and the indexing data will be written to cachefile afterwards. If set to false, FFVideoSource not look for an existing index file; instead all video tracks will be indexed when the script is opened, and the indexing data will be discarded after the script is closed; you will have to index again next time you open the script.
string cachefile = source + ".ffindex"
The filename of the index file (where the indexing data is saved). Defaults to sourcefilename.ffindex. Note that if you didn't change this parameter from its default value and FFVideoSource encounters an index file that doesn't seem to match the file it's trying to open, it will automatically reindex and then overwrite the old index file. On the other hand, if you do change it, FFVideoSource will assume you have your reasons and throw an error instead if the index doesn't match the file.
int fpsnum = -1, int fpsden = 1
Controls the framerate of the output; used for VFR to CFR conversions. If fpsnum is less than or equal to zero (the default), the output will contain the same frames that the input did, and the frame rate reported to Avisynth will be set based on the input clip's average frame duration. If fpsnum is greater than zero, FFVideoSource will force a constant frame rate, expressed as a rational number where fpsnum is the numerator and fpsden is the denominator. This may naturally cause FFVideoSource to drop or duplicate frames to achieve the desired frame rate, and the output is not guaranteed to have the same number of frames that the input did.
int threads = -1
The number of decoding threads to request from libavcodec. Setting it to less than or equal to zero means it defaults to the number of logical CPU's reported by Windows. Note that this setting might be completely ignored by libavcodec under a number of conditions; most commonly because a lot of decoders actually do not support multithreading.
string timecodes = ""
Filename to write Matroska v2 timecodes for the opened video track to. If the file exists, it will be truncated and overwritten. Set to the empty string to disable timecodes writing (this is the default).
int seekmode = 1
Controls how seeking is done. Mostly useful for getting uncooperative files to work. Only has an effect on files opened with the libavformat demuxer; on other files the equivalent of mode 1 is always used. Valid modes are:
  • -1: Linear access without rewind; i.e. will throw an error if each successive requested frame number isn't bigger than the last one. Only intended for opening images but might work on well with some obscure video format.
  • 0: Linear access (i.e. if you request frame n without having requested all frames from 0 to n-1 in order first, all frames from 0 to n will have to be decoded before n can be delivered). The definition of slow, but should make some formats "usable".
  • 1: Safe normal. Bases seeking decisions on the keyframe positions reported by libavformat.
  • 2: Unsafe normal. Same as mode 1, but no error will be thrown if the exact seek destination has to be guessed.
  • 3: Aggressive. Seeks in the forward direction even if no closer keyframe is known to exist. Only useful for testing and containers where libavformat doesn't report keyframes properly.
int rffmode = 0
Controls how RFF flags in the video stream are treated; in other words it's equivalent to the "field operation" mode switch in DVD2AVI/DGIndex. Valid modes are:
  • 0: Ignore all flags (the default mode).
  • 1: Honor all pulldown flags.
  • 2: Equivalent to DVD2AVI's "force film" mode.
Note that using modes 1 or 2 will make FFVideoSource throw an error if the video stream has no RFF flags at all. When using either of those modes, it will also make the output be assumed as CFR, disallow vertical scaling and disallow setting the output colorspace. FFPICT_TYPE will also not be set as the output is a combination of several frames. Other subtle behavior changes may also exist.
Also note that "force film" is mostly useless and only here for completeness' sake, since if your source really is safe to force film on, using mode 0 will have the exact same effect while being considerably more efficient.
int width = -1, int height = -1
Sets the resolution of the output video, in pixels. Setting either dimension to less than or equal to zero means the resolution of the first decoded video frame is used for that dimension. These parameters are mostly useful because FFMS2 supports video streams that change resolution mid-stream; since Avisynth does not, these parameters are used to set single resolution for the output.
string resizer = "BICUBIC"
The resizing algorithm to use if rescaling the image is necessary. If the video uses subsampled chroma but your chosen output colorspace does not, the chosen resizer will be used to upscale the chroma planes, even if you did not request an image rescaling. The available choices are FAST_BILINEAR, BILINEAR, BICUBIC (default), X, POINT, AREA, BICUBLIN, GAUSS, SINC, LANCZOS and SPLINE. Note that SPLINE is completely different from Avisynth's builtin Spline resizers.
string colorspace = ""
Convert the output from whatever it was to the given colorspace, which can be one of YV12, YUY2, RGB24 or RGB32. Setting this to an empty string (the default) means keeping the same colorspace as the input.
bool utf8 = false
Does the same thing as in FFIndex(); see that function for details.
string varprefix = ""
A string that is added as a prefix to all exported Avisynth variables. This makes it possible to differentiate between variables from different clips. For convenience the last used FFMS function in a script sets the global variable FFVAR_PREFIX to its own variable prefix so that FFInfo() can default to it.

FFAudioSource

FFAudioSource(string source, int track = -1, bool cache = true,
    string cachefile = source + ".ffindex", int adjustdelay = -1, bool utf8 = false,
	string varprefix = "")

Opens audio. Invokes indexing of all tracks if no valid index file is found, or if the requested track isn't present in the index.

Arguments

Are exactly the same as to FFVideoSource, with one exception:

int adjustdelay = -1
Controls how audio delay is handled, i.e. what happens if the first audio sample in the file doesn't have a timestamp of zero. The following arguments are valid:
  • -3: No adjustment is made; the first decodable audio sample becomes the first sample in the output.
  • -2: Samples are created (with silence) or discarded so that sample 0 in the decoded audio starts at time zero.
  • -1: Samples are created (with silence) or discarded so that sample 0 in the decoded audio starts at the same time as frame 0 of the first video track. This is the default, and probably what most people want.
  • Any integer >= 0: Same as -1, but adjust relative to the video track with the given track number instead. If the provided track number isn't a video track, an error is raised.
-2 obviously does the same thing as -1 if the first video frame of the first video track starts at time zero. In some containers this will always be the case, in others (most notably 188-byte MPEG TS) it will almost never happen.

FFmpegSource2

FFmpegSource2(string source, int vtrack = -1, int atrack = -2, bool cache = true,
    string cachefile = source + ".ffindex", int fpsnum = -1, int fpsden = 1,
    int threads = -1, string timecodes = "", int seekmode = 1,
    bool overwrite = false, int width = -1, int height = -1,
    string resizer = "BICUBIC", string colorspace = "", int rffmode = 0,
    int adjustdelay = -1, bool utf8 = false, string varprefix = "")

A convenience function that combines the functionality of FFVideoSource and FFAudioSource. The arguments do the same thing as in FFVideoSource and FFAudioSource; see those functions for details. vtrack and atrack are the video and audio track to open, respectively; setting atrack <= -2 means audio is disabled.

Note: this function is provided by FFMS2.avsi and is not available unless that script has been imported or autoloaded.

FFImageSource

FFImageSource(string source, int width = -1, int height = -1,
    string resizer = "BICUBIC", string colorspace = "", bool utf8 = false)

A convenience alias for FFVideoSource, with the options set optimally for using it as an image reader. Disables caching and seeking for maximum compatiblity.

Note: this function is provided by FFMS2.avsi and is not available unless that script has been imported or autoloaded.

SWScale

SWScale(clip, int width = -1, int height = -1, string resizer = "BICUBIC", string colorspace = "")

An image resizing and colorspace conversion filter. Does nothing special; it's almost always a better idea to just use Avisynth's builtins instead. Might potentially be useful for testing or odd experiments just because it does things in a different way from Avisynth. See the relevant arguments to FFVideoSource for details.

FFFormatTime

FFFormatTime(int ms)

A helper function used to format a time given in milliseconds into a h:mm:ss.ttt string. Used internally by FFInfo.

Note: this function is provided by FFMS2.avsi and is not available unless that script has been imported or autoloaded.

FFInfo

FFInfo(clip c, bool framenum = true, bool frametype = true, bool cfrtime = true,
	bool vfrtime = true, string varprefix = "")

A helper function similar to Avisynth's internal Info() function; shows general information about the current frame. Note that not all values are exported in all source modes, so some information may not always be shown. The arguments can be used to disable the drawing of certain information if so desired. Use the varprefix argument to determine which clip you want information about.

Note: this function is provided by FFMS2.avsi and is not available unless that script has been imported or autoloaded.

FFSetLogLevel

FFSetLogLevel(int Level = -8)

Sets the FFmpeg logging level, i.e. how much diagnostic spam it prints to STDERR. Since most applications that open Avisynth scripts do not provide a way to display things printed to STDERR, and since it's rather hard to make any sense of the printed messages unless you're quite familiar with FFmpeg internals, the usefulness of this function is rather limited for end users. It's mostly intended for debugging. Defaults to quiet (no messages printed); a list of meaningful values can be found in libavutil/log.h.

FFGetLogLevel

FFGetLogLevel()

Returns the current log level, as an integer.

FFGetVersion

FFGetVersion()

Returns the FFMS2 version, as a string.

Exported Avisynth variables

All variable names are prefixed by the varprefix argument to the respective FFVideoSource or FFAudioSource call that generated them.

FFSAR_NUM, FFSAR_DEN, FFSAR
The playback aspect ratio specified by the container. FFSAR_NUM and FFSAR_DEN make up the rational number of the ratio; FFSAR is only provided for convenience and may not be set in case it cannot be calculated (i.e. if FFSAR_DEN is zero).
FFCROP_LEFT, FFCROP_RIGHT, FFCROP_TOP, FFCROP_BOTTOM
The on-playback cropping specified by the container.
FFCOLOR_SPACE
The colorimetry the input claims to be using. Only meaningful for YUV inputs. The source for this variable is a metadata flag that can arbitrarily be set or manipulated at will by incompetent users or buggy programs without changing the actual video content, so blindly trusting its correctness is not recommended.
The value is exported as a cryptic numerical constant that matches the values in the MPEG-2 specification. You can find the gory details in the FFMS2 API documentation, but the important ones are:
  • 0: RGB (usually indicates the stream isn't actually YUV, but RGB flagged as YUV)
  • 1: ITU-R Rec.709
  • 2: Unknown or unspecified
  • 5 and 6: ITU-R Rec.601
FFCOLOR_RANGE
The color range the input video claims to be using. Much like FFCOLOR_SPACE, the source for this variable is a metadata flag that can freely be set to arbitrary values, so trusting it blindly might not be a good idea.
Note that using SWScale() or the width/height/colorspace parameters to FFVideoSource may under some circumstances change the output color range.
  • 0: Unknown/unspecified
  • 1: Limited range (usually 16-235)
  • 2: Full range (0-255)
FFPICT_TYPE
The picture type of the most recently requested frame as the ASCII number of the character listed below. Use Chr() to convert it to an actual letter in avisynth. Use after_frame=true in Avisynth's conditional scripting for proper results. Only set when rffmode=0. The FFmpeg source definition of the characters: 
I: Intra
P: Predicted
B: Bi-dir predicted
S: S(GMC)-VOP MPEG4
i: Switching Intra
p: Switching Predicted
b: FF_BI_TYPE (no good explanation available)
?: Unknown
FFVFR_TIME
The actual time of the source frame in milliseconds. Only set when no type of CFR conversion is being done (rffmode and fpsnum left at their defaults).
FFCHANNEL_LAYOUT
The audio channel layout of the audio stream. This is exported as a very cryptic integer that is constructed in the same way as the dwChannelMask property of the Windows WAVEFORMATEXTENSIBLE struct. If you don't know what a WAVEFORMATEXTENSIBLE is or what the dwChannelMask does, don't worry about it.
FFVAR_PREFIX
The variable prefix of the last called FFMS source function. Note that this is a global variable

    • Corrected handling of codec private data when using a non-libavformat parser. Fixes decoding of FFV1 and UTVideo in MKV, among other things. (TheFluff)
    • Bump minimum required version of FFmpeg to 0.6.
  • 2.16
    • Reimplemented output colorspace selection, this should fix all issues with the Avisynth plugin when opening yuv420p10 or yuv444 material plus several other less common cases. (Myrsloik)
    • Added FFMS_SetOutputFormatV2 to the API. This function allows you to specify PixelFormats >= 64 for use as output. (Myrsloik)
    • Fixed a serious bug that could cause crashes and completely useless index files with h264 in Matroska. (Myrsloik)
    • Automatically detect number of decoding threads. The Avisynth video source funtion already did this, now moved so the API can use it as well. (TheRyuu)
    • Re-add the ability to target x64 with MSVC, since it's a bit more sane now. (TheRyuu)
    • Fixed a bug that could cause crashes when reading audio if FFMS2 was compiled with GCC. (Myrsloik)
    • ffmsindex will no longer crash if it cannot open the file given to it for indexing. (TheFluff)
    • FFMS2 will no longer crash if the video decoder feeds it an empty frame (can sometimes happen when using lots of decoder threads); you'll get a nice error message instead. (TheFluff)
    • The C-plugin can now act as both an Avisynth 2.6 plugin (including support for new colorspaces) as well as an Avisynth 2.5 one, in the same binary. (kemuri_-9)
    • Fixed an issue that could cause opening Vorbis audio to fail because FFMS2 couldn't find an initial valid PTS. (TheFluff)
    • FFMS2 will no longer crash if forced or tricked into using an index file generated by a FFMS2 version compiled for a different architecture. (TheRyuu)
    • Fixed a crash when the last frame was requested using the Avisynth plugin's forced CFR mode. (Plorkyeran)
    • Fixed various issues with decoding audio from the Ogg container without Haali's splitter. (Myrsloik, TheFluff)
    • Fixed the "invalid postprocessing settings", it is caused by a parsing bug in libpostproc and a workaround has been added (Myrsloik)
    • Tinkered a bit with the non-MSVS build system. (Daemon404, Kovensky)
  • 2.15
    • FFVideoSource and FFAudioSource will now automatically reindex and overwrite the index file if it doesn't match the file being opened and the cachefile argument is left as the default. (Plorkyeran)
    • FFMS2 can now be used to decode Lagarith, but note that libavcodec's decoder is very experimental at the moment. (Plorkyeran)
    • SWScale can now use SSE2 optimizations for certain operations if your CPU supports it. (kemuri_-9)
    • Fixed a bug that could cause SWScale initialization to fail. (kemuri_-9)
    • Fixed a bug that could cause index files to never be considered valid, forcing a reindexing every time a script was loaded. (TheRyuu)
    • Trying to use postprocessing on a fullrange YUV clip will no longer cause errors. (TheFluff)
    • Fixed a few random decoding bugs related to unaligned memory or buffers that were not initialized properly. (TheFluff)
    • It is now possible to force FFMS2 to use a specific demuxer instead of letting it pick one automatically. (TheFluff)
    • When converting YUV to RGB, FFMS2 will now try to actually use the correct color coefficients rather than assuming everything is bt470bg. (Plorkyeran)
    • Moved support for container-level audio delay from the Avisynth plugin to the core and exposed it in the API (Plorkyeran)
    • Audio decoding has been substantially reworked. Linearly decoding audio now almost always works correctly and seeking is now actually sample-accurate for many formats. (Plorkyeran)
    • It is now possible to build 64bit versions of the plugin for use with Avisynth (and whatever else) from MSVC by means of black magic (this probably only works when the planets are aligned, also 64bit builds might require msvcr90.dll). (TheRyuu)
    • The Avisynth plugin now supports UTF8 filenames; ffmsindex.exe also supports Unicode filenames. FFMS_USE_UTF8_PATHS is now a runtime option instead of a compile-time one. (TheFluff)
    • The FFInfo() function (supplied by ffms2.avsi) will now round timestamps to nearest millisecond instead of truncating them. It's also been cleaned up in general and no longer relies on global variables. (Gavino)
    • Containers opened with libavformat will now report a framerate based on the average frame duration instead of the duration of the first frame, just like Matroska files and files opened with Haali's splitter does. Should fix CFR framerates being reported incorrectly in dumb containers like FLV. (TheFluff)
    • PC/TV luma range (16-235 versus 0-255) detection should now be a bit more reliable. (TheFluff)
    • Fixed a crash when opening files with Unicode filename support enabled. (Plorkyeran)
  • 2.14
    • Reworked filename handling a bit. Index files should no longer get a garbled name when using the Avisynth plugin and an input filename in the local codepage (issue 9), and FFMS_USE_UTF8_PATHS does no longer require patching ffmpeg. (TheFluff, nielsm)
    • Fixed a bunch of compiler warnings and added versioning for the shared library when building under Unix. (Kovensky)
    • Fixed an invalid memory access bug that could cause random crashes or other errors when opening files. (TheFluff)
    • The timebase for video tracks is now corrected if it's invalid. (kemuri_-9)
    • Fixed a number of multithreaded decoding issues. (kemuri_-9)
    • Use aligned memory for audio decoding buffers; fixes some crashes during audio decoding. (greg)
    • Fixed a bug that caused ffmsindex -c to fail. (chdheu)
    • Added support for MKV files using header stripping compression. (TheFluff)
    • It is now possible to compile FFMS2 using a ffmpeg without libpostproc compiled in (this will obviously cause postprocessing-related functions to fail). Hence it is now possible to build a GPL-free FFMS2, since the rest of ffmpeg can be compiled as LGPL. (TheFluff)
    • Audio streams that change channel layout, sample rate or bitdepth mid-stream will no longer cause crashes; an error will be raised during indexing instead. (TheFluff)
    • Fix a potential crash when ffmpeg thought it couldn't decode a certain format, but was wrong. Fixes issues with some FLV's. (Plorkyeran)
    • Fix heap corruption that could cause crashes and odd issues when opening H.264 in MPEG-TS with Haali's splitter. (Plorkyeran)
    • Fix a memleak when decoding H.264 in MPEG-TS using Haali's splitter. (kemuri-_9)
    • Updated FFmpeg to rev 25329.
  • 2.13
    • Fixed a bug where the Avisynth plugin would drop the last frame when converting to CFR (lanwcp)
    • The Avisynth plugin will now attempt to detect and use NTSC fractional framerates for CFR files if applicable, instead of reporting something based on the average framerate (astrange, TheFluff)
    • The errorhandling parameter to FFIndex() will now actually do what the documentation claims it does (TheFluff)
    • Fixed a progress reporting crash when opening images (TheFluff)
    • Replaced the CMake build system with an autotools one that hopefully works better (Kovensky)
    • Fixed various compilation issues with MinGW (TheFluff)
    • Fixed h264 in mkv which was remuxed from bd sources, there are no longer decoding artifacts after seeking
    • Use pts instead of dts for seeking with lavf, fixes various timecode problems on mp4 files with certain obscure delay headers
    • Now compresses the index files with zlib to save space
    • Removed the boost dependency
    • Fixed the framerate calculation for AVC video in the RFF modes
    • Improved/fixed the NVOP detection in MPEG4 and how timestamps are calculated (lanwcp, Myrsloik)
    • Fixed an issue where the first 15 audio frames would never be redecoded if needed again
    • Fixed/added support for uncompressed video and audio formats in matroska, fixes Blank.Clip.720p.x264-darkhold.mkv (Emess)
    • The indexer and test is now statically linked so no extra runtimes are needed
    • FFmpeg is now compiled with runtime cpu detection, allows opterons and old cpus to work properly
    • Updated FFmpeg to rev 21782
  • 2.12
    • Added support for (L)PCM in TS/PS
    • Fixed some possible memory corruption on initialization in the indexers
    • Improved the API slightly by making resolution and colorspace frame properties only like they actually are
    • Fixed adjustdelay=-1 when no video track is present, previously it would crash
    • Updated FFmpeg to rev 19824, FFmpeg-mt unchanged at 24/08/2009 - with faad2, opencore-amr nb/wb, and pthreads
  • 2.11
    • Now 100% less beta
    • FFMSIndex can now write timecode files
    • Optimized index reading and writing, file opening should be faster especially for big files
    • Fixed a crash bug on zlib compressed streams in matroska
    • Added an argument to FFAudioSource that makes it automatically adjust the delay relative to the first video track (default), the specified track (any track type possible) or relative to the zero timestamp, no adjustment is done for files with no video track in the default mode
    • Now exports the colorimetry info in a format easily usable with ColorMatrix, see FFCOLOR_SPACE and FFCOLOR_RANGE in the manual, the reported information may be unreliable
    • Added an FFImageSource() function to ffms2.avsi which invokes FFVideoSource with the optimal settings for use on images
    • Now exports the actual frame presentation time in FFVFR_TIME, added the general information function FFInfo() and FFFormatTime() functions to ffms2.avsi in addition to fixing the missing backslash
    • The seek/read method has been changed in the matroska video source to only need the information in the index and nothing more, this matches the audio source and should make seeking faster in some cases
    • No longer drops the last audio frame
    • It is now possible to force indexing of broken tracks when using FFIndex and from the API, this can in many cases help when the last frame of an avi file is corrupted which would otherwise prevent indexing of all working data
    • Fixed a bug that would prevent the SWScale and FFPP filters from working because of randomly added flags
    • Added support for RFF flags, the three possible modes should be equivalent to the ones found in DGDecode
    • Added a workaround for mpeg4 files with NVOPs
    • Fixed a bug where the first frame would be corrupted if the colorspace/dimensions were set for the output
    • Now VC1 in TS decoding works in many cases
    • Added the missing install target to CMake and changed the default output library name (Kovensky)
    • Now reverts to using LAVF if Haali's splitter isn't installed (note that LAVF is VERY bad at seeking in these formats)
    • Now requires the boost headers (but not libraries) to compile because boost::format is so convenient
    • More API changes to return proper error codes and more source cleanups
    • Updated FFmpeg to rev 19776, FFmpeg-mt to 24/08/2009 - with faad2, opencore-amr nb/wb, and w32threads (pthreads for FFmpeg-mt)
  • 2.00 beta 10
    • Possibly fixed h264 in transport stream decoding, now a suitable bitstream filter is added (could theoretically break other h264 in ts files so make sure to report if any such files stop working)
    • Now returns the frame type as a character to make presentation easier and to remove the random numbers from the API
    • Fixed the identification of certain codecs (like VC1) in some transport streams
    • Fixed a bug introduced in SeekMode=1 by the changes in beta 6, prevents an access violation from happening in very rare conditions
    • Some (but not all) stream properties are now retrieved from the container and passed to libavcodec, this makes a few more formats work like vc1 in mkv/ts
    • It is now possible to specify the desired output colorspace and resolution in FFVideoSource, this is mostly useful for file where the resolution changes to avoid excessive up/downscaling
    • Added support for files where the video frames have changing size and colorspace
    • The library part can now be compiled to accept UTF8 encoded strings, this allows full unicode support on windows when FFmpeg is compiled with a small patch applied (TheFluff)
    • Added proper detection of when the opened file and index is mismatched and throws an error when it happens instead of undefined behavior, should not add a noticable delay to file opening
    • Added a proper cmake based build system and vs2008 project files to make developement and use easier (TheFluff, JEEB, Kovensky)
    • Added API documentation by TheFluff and revised many argument descriptions to reflect how they currently work
    • The output audio filename can now be specified in avisynth (was ignored previously) with variables such as track number and delay possible to use
    • Indexing with Haali's splitters should now show progress in most cases
    • Fixed a few more memory leaks in indexing
    • Now checks for failed seeking when LAVF is used and retries with more aggressive seeking options before failing
    • Updated FFmpeg to rev 19479 (now compiled with the opencore amr decoder)
  • 2.00 beta 9
    • Dumping audio now actually implies indexing too in FFIndex, previously nothing would be done if the index mask wasn't set as well
    • FFAudioSource will now first load the index and returns the first indexed audio track with track=-1, if no audio tracks are indexed or the chosen track isn't indexed the equivalent of FFIndex(indexmask = -1, overwrite = cache) is executed first
    • Codec lookup for non-lavf opened files now to a large part use the same lookup tables as lavf, this should improve the number of properly recognized codecs
    • Now uses the average framerate for files opened with Haali's splitters, before it was always reported as 30 fps
    • Implemented audio decoding using Haali's splitters, FFAudioSource now works on ts, ps and ogm
    • Can now be compiled with ICL 10.1 (probably other versions too)
    • How indexing works has been split internally so the track numbers and types are reported, this makes it possible to create an interactive GUI or ask which audio tracks are to be indexed
    • Now has stricter index checking to detect when different FFmpeg versions were used to create an index of the same version
    • Fixed memory leaks when audio sources were destroyed and when errors happened during indexing
    • Fixed access violations occurring when a track of the wrong type was specified or didn't exist in FFVideoSource and FFAudioSource
    • Fixed access violations occurring when unindexed or empty audio tracks in matroska/lavf read files were opened
    • Less type conversion/signedness warnings
    • When audio track dumping is performed a custom callback can now be supplied to name the tracks
    • The audio track delay is now exposed in the API in the same way as video tracks
    • A big type and argument name cleanup in the API, many things have been renamed to be clearer and ffms.h should be completely C friendly now
    • Removed FFNoLog and replaced it with FFSetLogLevel and FFGetLogLevel, the default logging is now also set to quiet, the magical numbers to supply it can be found in avutil/log.h
    • Updated FFmpeg to rev 18972 (now with faad2 again by popular demand, updated to GCC 4.4.0 for compiling all libraries)
  • 2.00 beta 8
    • Improved the audio decoding quality a lot by adding a simple cache, no more seeking is done when playing a file linearly and pops and other artifacts should be much more uncommon
    • Fixed a bug that would most of the time drop frame 0 and sometimes frame 1
    • Updated Haali's matroska parser code to the latest version
    • Updated FFmpeg to rev 18774
  • 2.00 beta 7
    • Using ffms2 as a library no longer requires an installed pixfmt.h from libavutil, it is however still required to compile ffms2 and the avisynth plugin part
    • Fix a crash bug at the end of files with b-frames in beta 6 caused by uninitialized null packets
    • Includes TheFluff's wrapper function for 1.21 style syntax
    • Added a simple regression test application to the source
    • Removed a few pointless functions from the API
    • Fixed the accessing of codecprivate data with Haali's splitters
    • Timecode output should be fixed to include decimals AND not be in scientific format
    • Fixed a memory leak when using Haali's splitters
    • Updated FFmpeg to rev 18717
  • 2.00 beta 6
    • Haali's splitters have been improved for video and now have audio dumping during indexing implemented
    • SeekMode=1 has improved logic which will make it go back and decode more frames if necessary to figure out where it is, in theory SeekMode=0 should now be mostly obsolete
    • Haali's splitters are now used to open mpeg ps and ogm in addition to mpeg ts, only ogm is frame accurate at this time
    • Negative timecodes and other bugs caused by an integer overflow fixed
    • Updated FFmpeg to rev 18442 (once again compilation fixes for the changes)
  • 2.00 beta 5
    • FFMSIndex should now print the progress properly when another application reads its output
    • Added missing variables and explanations to the manual
    • Can now directly be compiled as a library for use in *nix
    • Fixed the missing decimals in saved timecode files
  • 2.00 beta 4
    • Added the function FFNoLog which suppresses all messages from ffmpeg
    • Experimental new TS parsing using Haali's splitter (with bugs)
    • Everything is now compiled with VS2008 and GCC 4.3.2
    • Updated FFmpeg to rev 16383 (no libfaad2 this time)
  • 2.00 beta 3
    • Compiled with libfaad2 again (has anyone seen a single aac file lavc can open right now?)
    • More API changes (and even more are likely to come)
    • Several access violations and memory leaks on opening and indexing files fixed
    • Added a VFR to CFR mode
    • Readded FFAudioSource support for other containers (glitches still present now and then but no separate raw cache is required and possibly less buggy)

    • Updated FFmpeg to rev 15522
  • 2.00 beta 2
    • More API changes (and more are likely to come)
    • Includes a simple CLI indexing application

    • Readded FFAudioSource (only matroska supported for now)
    • Updated FFmpeg to rev 15396
  • 2.00 beta 1
    • Can now be used as a stand alone library for making indices and retrieving frames
    • Rewrote most things
    • Updated FFmpeg to rev 15301

Everyone is permitted to copy and distribute verbatim copies of this license document, but changing it is not allowed. Preamble The GNU General Public License is a free, copyleft license for software and other kinds of works. The licenses for most software and other practical works are designed to take away your freedom to share and change the works. By contrast, the GNU General Public License is intended to guarantee your freedom to share and change all versions of a program--to make sure it remains free software for all its users. We, the Free Software Foundation, use the GNU General Public License for most of our software; it applies also to any other work released this way by its authors. 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 them 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 prevent others from denying you these rights or asking you to surrender the rights. Therefore, you have certain responsibilities if you distribute copies of the software, or if you modify it: responsibilities to respect the freedom of others. For example, if you distribute copies of such a program, whether gratis or for a fee, you must pass on to the recipients the same freedoms that you received. 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. Developers that use the GNU GPL protect your rights with two steps: (1) assert copyright on the software, and (2) offer you this License giving you legal permission to copy, distribute and/or modify it. For the developers' and authors' protection, the GPL clearly explains that there is no warranty for this free software. For both users' and authors' sake, the GPL requires that modified versions be marked as changed, so that their problems will not be attributed erroneously to authors of previous versions. Some devices are designed to deny users access to install or run modified versions of the software inside them, although the manufacturer can do so. This is fundamentally incompatible with the aim of protecting users' freedom to change the software. The systematic pattern of such abuse occurs in the area of products for individuals to use, which is precisely where it is most unacceptable. Therefore, we have designed this version of the GPL to prohibit the practice for those products. If such problems arise substantially in other domains, we stand ready to extend this provision to those domains in future versions of the GPL, as needed to protect the freedom of users. Finally, every program is threatened constantly by software patents. States should not allow patents to restrict development and use of software on general-purpose computers, but in those that do, we wish to avoid the special danger that patents applied to a free program could make it effectively proprietary. To prevent this, the GPL assures that patents cannot be used to render the program non-free. The precise terms and conditions for copying, distribution and modification follow. TERMS AND CONDITIONS 0. Definitions. "This License" refers to version 3 of the GNU General Public License. "Copyright" also means copyright-like laws that apply to other kinds of works, such as semiconductor masks. "The Program" refers to any copyrightable work licensed under this License. Each licensee is addressed as "you". "Licensees" and "recipients" may be individuals or organizations. To "modify" a work means to copy from or adapt all or part of the work in a fashion requiring copyright permission, other than the making of an exact copy. The resulting work is called a "modified version" of the earlier work or a work "based on" the earlier work. A "covered work" means either the unmodified Program or a work based on the Program. To "propagate" a work means to do anything with it that, without permission, would make you directly or secondarily liable for infringement under applicable copyright law, except executing it on a computer or modifying a private copy. Propagation includes copying, distribution (with or without modification), making available to the public, and in some countries other activities as well. To "convey" a work means any kind of propagation that enables other parties to make or receive copies. Mere interaction with a user through a computer network, with no transfer of a copy, is not conveying. An interactive user interface displays "Appropriate Legal Notices" to the extent that it includes a convenient and prominently visible feature that (1) displays an appropriate copyright notice, and (2) tells the user that there is no warranty for the work (except to the extent that warranties are provided), that licensees may convey the work under this License, and how to view a copy of this License. If the interface presents a list of user commands or options, such as a menu, a prominent item in the list meets this criterion. 1. Source Code. The "source code" for a work means the preferred form of the work for making modifications to it. "Object code" means any non-source form of a work. A "Standard Interface" means an interface that either is an official standard defined by a recognized standards body, or, in the case of interfaces specified for a particular programming language, one that is widely used among developers working in that language. The "System Libraries" of an executable work include anything, other than the work as a whole, that (a) is included in the normal form of packaging a Major Component, but which is not part of that Major Component, and (b) serves only to enable use of the work with that Major Component, or to implement a Standard Interface for which an implementation is available to the public in source code form. A "Major Component", in this context, means a major essential component (kernel, window system, and so on) of the specific operating system (if any) on which the executable work runs, or a compiler used to produce the work, or an object code interpreter used to run it. The "Corresponding Source" for a work in object code form means all the source code needed to generate, install, and (for an executable work) run the object code and to modify the work, including scripts to control those activities. However, it does not include the work's System Libraries, or general-purpose tools or generally available free programs which are used unmodified in performing those activities but which are not part of the work. For example, Corresponding Source includes interface definition files associated with source files for the work, and the source code for shared libraries and dynamically linked subprograms that the work is specifically designed to require, such as by intimate data communication or control flow between those subprograms and other parts of the work. The Corresponding Source need not include anything that users can regenerate automatically from other parts of the Corresponding Source. The Corresponding Source for a work in source code form is that same work. 2. Basic Permissions. All rights granted under this License are granted for the term of copyright on the Program, and are irrevocable provided the stated conditions are met. This License explicitly affirms your unlimited permission to run the unmodified Program. The output from running a covered work is covered by this License only if the output, given its content, constitutes a covered work. This License acknowledges your rights of fair use or other equivalent, as provided by copyright law. You may make, run and propagate covered works that you do not convey, without conditions so long as your license otherwise remains in force. You may convey covered works to others for the sole purpose of having them make modifications exclusively for you, or provide you with facilities for running those works, provided that you comply with the terms of this License in conveying all material for which you do not control copyright. Those thus making or running the covered works for you must do so exclusively on your behalf, under your direction and control, on terms that prohibit them from making any copies of your copyrighted material outside their relationship with you. Conveying under any other circumstances is permitted solely under the conditions stated below. Sublicensing is not allowed; section 10 makes it unnecessary. 3. Protecting Users' Legal Rights From Anti-Circumvention Law. No covered work shall be deemed part of an effective technological measure under any applicable law fulfilling obligations under article 11 of the WIPO copyright treaty adopted on 20 December 1996, or similar laws prohibiting or restricting circumvention of such measures. When you convey a covered work, you waive any legal power to forbid circumvention of technological measures to the extent such circumvention is effected by exercising rights under this License with respect to the covered work, and you disclaim any intention to limit operation or modification of the work as a means of enforcing, against the work's users, your or third parties' legal rights to forbid circumvention of technological measures. 4. Conveying Verbatim Copies. You may convey 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; keep intact all notices stating that this License and any non-permissive terms added in accord with section 7 apply to the code; keep intact all notices of the absence of any warranty; and give all recipients a copy of this License along with the Program. You may charge any price or no price for each copy that you convey, and you may offer support or warranty protection for a fee. 5. Conveying Modified Source Versions. You may convey a work based on the Program, or the modifications to produce it from the Program, in the form of source code under the terms of section 4, provided that you also meet all of these conditions: a) The work must carry prominent notices stating that you modified it, and giving a relevant date. b) The work must carry prominent notices stating that it is released under this License and any conditions added under section 7. This requirement modifies the requirement in section 4 to "keep intact all notices". c) You must license the entire work, as a whole, under this License to anyone who comes into possession of a copy. This License will therefore apply, along with any applicable section 7 additional terms, to the whole of the work, and all its parts, regardless of how they are packaged. This License gives no permission to license the work in any other way, but it does not invalidate such permission if you have separately received it. d) If the work has interactive user interfaces, each must display Appropriate Legal Notices; however, if the Program has interactive interfaces that do not display Appropriate Legal Notices, your work need not make them do so. A compilation of a covered work with other separate and independent works, which are not by their nature extensions of the covered work, and which are not combined with it such as to form a larger program, in or on a volume of a storage or distribution medium, is called an "aggregate" if the compilation and its resulting copyright are not used to limit the access or legal rights of the compilation's users beyond what the individual works permit. Inclusion of a covered work in an aggregate does not cause this License to apply to the other parts of the aggregate. 6. Conveying Non-Source Forms. You may convey a covered work in object code form under the terms of sections 4 and 5, provided that you also convey the machine-readable Corresponding Source under the terms of this License, in one of these ways: a) Convey the object code in, or embodied in, a physical product (including a physical distribution medium), accompanied by the Corresponding Source fixed on a durable physical medium customarily used for software interchange. b) Convey the object code in, or embodied in, a physical product (including a physical distribution medium), accompanied by a written offer, valid for at least three years and valid for as long as you offer spare parts or customer support for that product model, to give anyone who possesses the object code either (1) a copy of the Corresponding Source for all the software in the product that is covered by this License, on a durable physical medium customarily used for software interchange, for a price no more than your reasonable cost of physically performing this conveying of source, or (2) access to copy the Corresponding Source from a network server at no charge. c) Convey individual copies of the object code with a copy of the written offer to provide the Corresponding Source. This alternative is allowed only occasionally and noncommercially, and only if you received the object code with such an offer, in accord with subsection 6b. d) Convey the object code by offering access from a designated place (gratis or for a charge), and offer equivalent access to the Corresponding Source in the same way through the same place at no further charge. You need not require recipients to copy the Corresponding Source along with the object code. If the place to copy the object code is a network server, the Corresponding Source may be on a different server (operated by you or a third party) that supports equivalent copying facilities, provided you maintain clear directions next to the object code saying where to find the Corresponding Source. Regardless of what server hosts the Corresponding Source, you remain obligated to ensure that it is available for as long as needed to satisfy these requirements. e) Convey the object code using peer-to-peer transmission, provided you inform other peers where the object code and Corresponding Source of the work are being offered to the general public at no charge under subsection 6d. A separable portion of the object code, whose source code is excluded from the Corresponding Source as a System Library, need not be included in conveying the object code work. A "User Product" is either (1) a "consumer product", which means any tangible personal property which is normally used for personal, family, or household purposes, or (2) anything designed or sold for incorporation into a dwelling. In determining whether a product is a consumer product, doubtful cases shall be resolved in favor of coverage. For a particular product received by a particular user, "normally used" refers to a typical or common use of that class of product, regardless of the status of the particular user or of the way in which the particular user actually uses, or expects or is expected to use, the product. A product is a consumer product regardless of whether the product has substantial commercial, industrial or non-consumer uses, unless such uses represent the only significant mode of use of the product. "Installation Information" for a User Product means any methods, procedures, authorization keys, or other information required to install and execute modified versions of a covered work in that User Product from a modified version of its Corresponding Source. The information must suffice to ensure that the continued functioning of the modified object code is in no case prevented or interfered with solely because modification has been made. If you convey an object code work under this section in, or with, or specifically for use in, a User Product, and the conveying occurs as part of a transaction in which the right of possession and use of the User Product is transferred to the recipient in perpetuity or for a fixed term (regardless of how the transaction is characterized), the Corresponding Source conveyed under this section must be accompanied by the Installation Information. But this requirement does not apply if neither you nor any third party retains the ability to install modified object code on the User Product (for example, the work has been installed in ROM). The requirement to provide Installation Information does not include a requirement to continue to provide support service, warranty, or updates for a work that has been modified or installed by the recipient, or for the User Product in which it has been modified or installed. Access to a network may be denied when the modification itself materially and adversely affects the operation of the network or violates the rules and protocols for communication across the network. Corresponding Source conveyed, and Installation Information provided, in accord with this section must be in a format that is publicly documented (and with an implementation available to the public in source code form), and must require no special password or key for unpacking, reading or copying. 7. Additional Terms. "Additional permissions" are terms that supplement the terms of this License by making exceptions from one or more of its conditions. Additional permissions that are applicable to the entire Program shall be treated as though they were included in this License, to the extent that they are valid under applicable law. If additional permissions apply only to part of the Program, that part may be used separately under those permissions, but the entire Program remains governed by this License without regard to the additional permissions. When you convey a copy of a covered work, you may at your option remove any additional permissions from that copy, or from any part of it. (Additional permissions may be written to require their own removal in certain cases when you modify the work.) You may place additional permissions on material, added by you to a covered work, for which you have or can give appropriate copyright permission. Notwithstanding any other provision of this License, for material you add to a covered work, you may (if authorized by the copyright holders of that material) supplement the terms of this License with terms: a) Disclaiming warranty or limiting liability differently from the terms of sections 15 and 16 of this License; or b) Requiring preservation of specified reasonable legal notices or author attributions in that material or in the Appropriate Legal Notices displayed by works containing it; or c) Prohibiting misrepresentation of the origin of that material, or requiring that modified versions of such material be marked in reasonable ways as different from the original version; or d) Limiting the use for publicity purposes of names of licensors or authors of the material; or e) Declining to grant rights under trademark law for use of some trade names, trademarks, or service marks; or f) Requiring indemnification of licensors and authors of that material by anyone who conveys the material (or modified versions of it) with contractual assumptions of liability to the recipient, for any liability that these contractual assumptions directly impose on those licensors and authors. All other non-permissive additional terms are considered "further restrictions" within the meaning of section 10. If the Program as you received it, or any part of it, contains a notice stating that it is governed by this License along with a term that is a further restriction, you may remove that term. If a license document contains a further restriction but permits relicensing or conveying under this License, you may add to a covered work material governed by the terms of that license document, provided that the further restriction does not survive such relicensing or conveying. If you add terms to a covered work in accord with this section, you must place, in the relevant source files, a statement of the additional terms that apply to those files, or a notice indicating where to find the applicable terms. Additional terms, permissive or non-permissive, may be stated in the form of a separately written license, or stated as exceptions; the above requirements apply either way. 8. Termination. You may not propagate or modify a covered work except as expressly provided under this License. Any attempt otherwise to propagate or modify it is void, and will automatically terminate your rights under this License (including any patent licenses granted under the third paragraph of section 11). However, if you cease all violation of this License, then your license from a particular copyright holder is reinstated (a) provisionally, unless and until the copyright holder explicitly and finally terminates your license, and (b) permanently, if the copyright holder fails to notify you of the violation by some reasonable means prior to 60 days after the cessation. Moreover, your license from a particular copyright holder is reinstated permanently if the copyright holder notifies you of the violation by some reasonable means, this is the first time you have received notice of violation of this License (for any work) from that copyright holder, and you cure the violation prior to 30 days after your receipt of the notice. Termination of your rights under this section does not terminate the licenses of parties who have received copies or rights from you under this License. If your rights have been terminated and not permanently reinstated, you do not qualify to receive new licenses for the same material under section 10. 9. Acceptance Not Required for Having Copies. You are not required to accept this License in order to receive or run a copy of the Program. Ancillary propagation of a covered work occurring solely as a consequence of using peer-to-peer transmission to receive a copy likewise does not require acceptance. However, nothing other than this License grants you permission to propagate or modify any covered work. These actions infringe copyright if you do not accept this License. Therefore, by modifying or propagating a covered work, you indicate your acceptance of this License to do so. 10. Automatic Licensing of Downstream Recipients. Each time you convey a covered work, the recipient automatically receives a license from the original licensors, to run, modify and propagate that work, subject to this License. You are not responsible for enforcing compliance by third parties with this License. An "entity transaction" is a transaction transferring control of an organization, or substantially all assets of one, or subdividing an organization, or merging organizations. If propagation of a covered work results from an entity transaction, each party to that transaction who receives a copy of the work also receives whatever licenses to the work the party's predecessor in interest had or could give under the previous paragraph, plus a right to possession of the Corresponding Source of the work from the predecessor in interest, if the predecessor has it or can get it with reasonable efforts. You may not impose any further restrictions on the exercise of the rights granted or affirmed under this License. For example, you may not impose a license fee, royalty, or other charge for exercise of rights granted under this License, and you may not initiate litigation (including a cross-claim or counterclaim in a lawsuit) alleging that any patent claim is infringed by making, using, selling, offering for sale, or importing the Program or any portion of it. 11. Patents. A "contributor" is a copyright holder who authorizes use under this License of the Program or a work on which the Program is based. The work thus licensed is called the contributor's "contributor version". A contributor's "essential patent claims" are all patent claims owned or controlled by the contributor, whether already acquired or hereafter acquired, that would be infringed by some manner, permitted by this License, of making, using, or selling its contributor version, but do not include claims that would be infringed only as a consequence of further modification of the contributor version. For purposes of this definition, "control" includes the right to grant patent sublicenses in a manner consistent with the requirements of this License. Each contributor grants you a non-exclusive, worldwide, royalty-free patent license under the contributor's essential patent claims, to make, use, sell, offer for sale, import and otherwise run, modify and propagate the contents of its contributor version. In the following three paragraphs, a "patent license" is any express agreement or commitment, however denominated, not to enforce a patent (such as an express permission to practice a patent or covenant not to sue for patent infringement). To "grant" such a patent license to a party means to make such an agreement or commitment not to enforce a patent against the party. If you convey a covered work, knowingly relying on a patent license, and the Corresponding Source of the work is not available for anyone to copy, free of charge and under the terms of this License, through a publicly available network server or other readily accessible means, then you must either (1) cause the Corresponding Source to be so available, or (2) arrange to deprive yourself of the benefit of the patent license for this particular work, or (3) arrange, in a manner consistent with the requirements of this License, to extend the patent license to downstream recipients. "Knowingly relying" means you have actual knowledge that, but for the patent license, your conveying the covered work in a country, or your recipient's use of the covered work in a country, would infringe one or more identifiable patents in that country that you have reason to believe are valid. If, pursuant to or in connection with a single transaction or arrangement, you convey, or propagate by procuring conveyance of, a covered work, and grant a patent license to some of the parties receiving the covered work authorizing them to use, propagate, modify or convey a specific copy of the covered work, then the patent license you grant is automatically extended to all recipients of the covered work and works based on it. A patent license is "discriminatory" if it does not include within the scope of its coverage, prohibits the exercise of, or is conditioned on the non-exercise of one or more of the rights that are specifically granted under this License. You may not convey a covered work if you are a party to an arrangement with a third party that is in the business of distributing software, under which you make payment to the third party based on the extent of your activity of conveying the work, and under which the third party grants, to any of the parties who would receive the covered work from you, a discriminatory patent license (a) in connection with copies of the covered work conveyed by you (or copies made from those copies), or (b) primarily for and in connection with specific products or compilations that contain the covered work, unless you entered into that arrangement, or that patent license was granted, prior to 28 March 2007. Nothing in this License shall be construed as excluding or limiting any implied license or other defenses to infringement that may otherwise be available to you under applicable patent law. 12. No Surrender of Others' Freedom. If 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 convey a covered work so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may not convey it at all. For example, if you agree to terms that obligate you to collect a royalty for further conveying from those to whom you convey the Program, the only way you could satisfy both those terms and this License would be to refrain entirely from conveying the Program. 13. Use with the GNU Affero General Public License. Notwithstanding any other provision of this License, you have permission to link or combine any covered work with a work licensed under version 3 of the GNU Affero General Public License into a single combined work, and to convey the resulting work. The terms of this License will continue to apply to the part which is the covered work, but the special requirements of the GNU Affero General Public License, section 13, concerning interaction through a network will apply to the combination as such. 14. Revised Versions of this License. The Free Software Foundation may publish revised and/or new versions of the GNU 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 that a certain numbered version of the GNU General Public License "or any later version" applies to it, you have the option of following the terms and conditions either of that numbered version or of any later version published by the Free Software Foundation. If the Program does not specify a version number of the GNU General Public License, you may choose any version ever published by the Free Software Foundation. If the Program specifies that a proxy can decide which future versions of the GNU General Public License can be used, that proxy's public statement of acceptance of a version permanently authorizes you to choose that version for the Program. Later license versions may give you additional or different permissions. However, no additional obligations are imposed on any author or copyright holder as a result of your choosing to follow a later version. 15. Disclaimer of Warranty. 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. 16. Limitation of Liability. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS 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. 17. Interpretation of Sections 15 and 16. If the disclaimer of warranty and limitation of liability provided above cannot be given local legal effect according to their terms, reviewing courts shall apply local law that most closely approximates an absolute waiver of all civil liability in connection with the Program, unless a warranty or assumption of liability accompanies a copy of the Program in return for a fee. 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 state 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 3 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, see . Also add information on how to contact you by electronic and paper mail. If the program does terminal interaction, make it output a short notice like this when it starts in an interactive mode: Copyright (C) This program 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, your program's commands might be different; for a GUI interface, you would use an "about box". You should also get your employer (if you work as a programmer) or school, if any, to sign a "copyright disclaimer" for the program, if necessary. For more information on this, and how to apply and follow the GNU GPL, see . The GNU 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.
