1. external libraries

FFmpeg can be hooked up with a number of external libraries to add support for more formats. None of them are used by default, their use has to be explicitly requested by passing the appropriate flags to ‘./configure’.

1.1 AMR

AMR comes in two different flavors, wideband and narrowband. FFmpeg can make use of the AMR wideband (floating-point mode) and the AMR narrowband (floating-point mode) reference decoders and encoders.

Go to http://www.penguin.cz/~utx/amr and follow the instructions for installing the libraries. Then pass --enable-libamr-nb and/or --enable-libamr-wb to configure to enable the libraries.

Note that libamr is copyrighted without any sort of license grant. This means that you can use it if you legally obtained it but you are not allowed to redistribute it in any way. Any FFmpeg binaries with libamr support you create are non-free and unredistributable!

2. Supported File Formats and Codecs

You can use the -formats option to have an exhaustive list.

2.1 File Formats

FFmpeg supports the following file formats through the libavformat library:

X means that encoding (resp. decoding) is supported.

2.2 Image Formats

FFmpeg can read and write images for each frame of a video sequence. The following image formats are supported:

X means that encoding (resp. decoding) is supported.

2.3 Video Codecs

X means that encoding (resp. decoding) is supported.

2.4 Audio Codecs

X means that encoding (resp. decoding) is supported.

I means that an integer-only version is available, too (ensures high performance on systems without hardware floating point support).

3. Platform Specific information

3.1 BSD

BSD make will not build FFmpeg, you need to install and use GNU Make (‘gmake’).

3.2 Windows

To get help and instructions for building FFmpeg under Windows, check out the FFmpeg Windows Help Forum at http://arrozcru.no-ip.org/ffmpeg/.

3.2.1 Native Windows compilation

FFmpeg can be built to run natively on Windows using the MinGW tools. Install the current versions of MSYS and MinGW from http://www.mingw.org/. Also install the coreutils package. You can find detailed installation instructions in the download section and the FAQ.

Within the MSYS shell, configure and make with:

./configure --enable-memalign-hack
make
make install

This will install ‘ffmpeg.exe’ along with many other development files to ‘/usr/local’. You may specify another install path using the --prefix option in ‘configure’.

Notes:

• Use at least bash 3.1. Older versions are known to fail on the configure script.
• In order to compile vhooks, you must have a POSIX-compliant libdl in your MinGW system. Get dlfcn-win32 from http://code.google.com/p/dlfcn-win32.
• In order to compile FFplay, you must have the MinGW development library of SDL. Get it from http://www.libsdl.org. Edit the ‘bin/sdl-config’ script so that it points to the correct prefix where SDL was installed. Verify that ‘sdl-config’ can be launched from the MSYS command line.
• The target make wininstaller can be used to create a Nullsoft-based Windows installer for FFmpeg and FFplay. ‘SDL.dll’ must be copied to the FFmpeg directory in order to build the installer.
• By using ./configure --enable-shared when configuring FFmpeg, you can build libavutil, libavcodec and libavformat as DLLs.

3.2.2 Microsoft Visual C++ compatibility

As stated in the FAQ, FFmpeg will not compile under MSVC++. However, if you want to use the libav* libraries in your own applications, you can still compile those applications using MSVC++.
