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 Alliance for Open Media (AOM)

FFmpeg can make use of the AOM library for AV1 decoding and encoding.

Go to http://aomedia.org/ and follow the instructions for installing the library. Then pass --enable-libaom to configure to enable it.

1.2 AMD AMF/VCE

FFmpeg can use the AMD Advanced Media Framework library for accelerated H.264 and HEVC(only windows) encoding on hardware with Video Coding Engine (VCE).

To enable support you must obtain the AMF framework header files(version 1.4.9+) from https://github.com/GPUOpen-LibrariesAndSDKs/AMF.git.

Create an AMF/ directory in the system include path. Copy the contents of AMF/amf/public/include/ into that directory. Then configure FFmpeg with --enable-amf.

Initialization of amf encoder occurs in this order: 1) trying to initialize through dx11(only windows) 2) trying to initialize through dx9(only windows) 3) trying to initialize through vulkan

To use h.264(AMD VCE) encoder on linux amdgru-pro version 19.20+ and amf-amdgpu-pro package(amdgru-pro contains, but does not install automatically) are required.

This driver can be installed using amdgpu-pro-install script in official amd driver archive.

1.3 AviSynth

FFmpeg can read AviSynth scripts as input. To enable support, pass --enable-avisynth to configure after installing the headers provided by AviSynth+. AviSynth+ can be configured to install only the headers by either passing -DHEADERS_ONLY:bool=on to the normal CMake-based build system, or by using the supplied GNUmakefile.

For Windows, supported AviSynth variants are AviSynth 2.6 RC1 or higher for 32-bit builds and AviSynth+ r1718 or higher for 32-bit and 64-bit builds.

For Linux, macOS, and BSD, the only supported AviSynth variant is AviSynth+, starting with version 3.5.

In 2016, AviSynth+ added support for building with GCC. However, due to the eccentricities of Windows’ calling conventions, 32-bit GCC builds of AviSynth+ are not compatible with typical 32-bit builds of FFmpeg.

By default, FFmpeg assumes compatibility with 32-bit MSVC builds of AviSynth+ since that is the most widely-used and entrenched build configuration. Users can override this and enable support for 32-bit GCC builds of AviSynth+ by passing -DAVSC_WIN32_GCC32 to --extra-cflags when configuring FFmpeg.

64-bit builds of FFmpeg are not affected, and can use either MSVC or GCC builds of AviSynth+ without any special flags.

AviSynth(+) is loaded dynamically. Distributors can build FFmpeg with --enable-avisynth, and the binaries will work regardless of the end user having AviSynth installed. If/when an end user would like to use AviSynth scripts, then they can install AviSynth(+) and FFmpeg will be able to find and use it to open scripts.

1.4 Chromaprint

FFmpeg can make use of the Chromaprint library for generating audio fingerprints. Pass --enable-chromaprint to configure to enable it. See https://acoustid.org/chromaprint.

1.5 codec2

FFmpeg can make use of the codec2 library for codec2 decoding and encoding. There is currently no native decoder, so libcodec2 must be used for decoding.

Go to http://freedv.org/, download "Codec 2 source archive". Build and install using CMake. Debian users can install the libcodec2-dev package instead. Once libcodec2 is installed you can pass --enable-libcodec2 to configure to enable it.

The easiest way to use codec2 is with .c2 files, since they contain the mode information required for decoding. To encode such a file, use a .c2 file extension and give the libcodec2 encoder the -mode option: ffmpeg -i input.wav -mode 700C output.c2. Playback is as simple as ffplay output.c2. For a list of supported modes, run ffmpeg -h encoder=libcodec2. Raw codec2 files are also supported. To make sense of them the mode in use needs to be specified as a format option: ffmpeg -f codec2raw -mode 1300 -i input.raw output.wav.

1.6 dav1d

FFmpeg can make use of the dav1d library for AV1 video decoding.

Go to https://code.videolan.org/videolan/dav1d and follow the instructions for installing the library. Then pass --enable-libdav1d to configure to enable it.

FFmpeg can make use of the davs2 library for AVS2-P2/IEEE1857.4 video decoding.

Go to https://github.com/pkuvcl/davs2 and follow the instructions for installing the library. Then pass --enable-libdavs2 to configure to enable it.

libdavs2 is under the GNU Public License Version 2 or later (see http://www.gnu.org/licenses/old-licenses/gpl-2.0.html for details), you must upgrade FFmpeg’s license to GPL in order to use it.

1.8 uavs3d

FFmpeg can make use of the uavs3d library for AVS3-P2/IEEE1857.10 video decoding.

Go to https://github.com/uavs3/uavs3d and follow the instructions for installing the library. Then pass --enable-libuavs3d to configure to enable it.

1.9 Game Music Emu

FFmpeg can make use of the Game Music Emu library to read audio from supported video game music file formats. Pass --enable-libgme to configure to enable it. See https://bitbucket.org/mpyne/game-music-emu/overview.

1.10 Intel QuickSync Video

FFmpeg can use Intel QuickSync Video (QSV) for accelerated decoding and encoding of multiple codecs. To use QSV, FFmpeg must be linked against the libmfx dispatcher, which loads the actual decoding libraries.

The dispatcher is open source and can be downloaded from https://github.com/lu-zero/mfx_dispatch.git. FFmpeg needs to be configured with the --enable-libmfx option and pkg-config needs to be able to locate the dispatcher’s .pc files.

1.11 Kvazaar

1.18 OpenCORE, VisualOn, and Fraunhofer libraries

Spun off Google Android sources, OpenCore, VisualOn and Fraunhofer libraries provide encoders for a number of audio codecs.

OpenCORE and VisualOn libraries are under the Apache License 2.0 (see http://www.apache.org/licenses/LICENSE-2.0 for details), which is incompatible to the LGPL version 2.1 and GPL version 2. You have to upgrade FFmpeg’s license to LGPL version 3 (or if you have enabled GPL components, GPL version 3) by passing --enable-version3 to configure in order to use it.

The license of the Fraunhofer AAC library is incompatible with the GPL. Therefore, for GPL builds, you have to pass --enable-nonfree to configure in order to use it. To the best of our knowledge, it is compatible with the LGPL.

1.18.1 OpenCORE AMR

FFmpeg can make use of the OpenCORE libraries for AMR-NB decoding/encoding and AMR-WB decoding.

Go to http://sourceforge.net/projects/opencore-amr/ and follow the instructions for installing the libraries. Then pass --enable-libopencore-amrnb and/or --enable-libopencore-amrwb to configure to enable them.
