None of them are used by default, their use has to be 17explicitly requested by passing the appropriate flags to 18@command{./configure}. 19 20@section Alliance for Open Media (AOM) 21 22FFmpeg can make use of the AOM library for AV1 decoding and encoding. 23 24Go to @url{http://aomedia.org/} and follow the instructions for 25installing the library. Then pass @code{--enable-libaom} to configure to 26enable it. 27 28@section AMD AMF/VCE 29 30FFmpeg can use the AMD Advanced Media Framework library 31for accelerated H.264 and HEVC(only windows) encoding on hardware with Video Coding Engine (VCE). 32 33To enable support you must obtain the AMF framework header files(version 1.4.9+) from 34@url{https://github.com/GPUOpen-LibrariesAndSDKs/AMF.git}. 35 36Create an @code{AMF/} directory in the system include path. 37Copy the contents of @code{AMF/amf/public/include/} into that directory. 38Then configure FFmpeg with @code{--enable-amf}. 39 40Initialization of amf encoder occurs in this order: 411) trying to initialize through dx11(only windows) 422) trying to initialize through dx9(only windows) 433) trying to initialize through vulkan 44 45To use h.264(AMD VCE) encoder on linux amdgru-pro version 19.20+ and amf-amdgpu-pro 46package(amdgru-pro contains, but does not install automatically) are required. 47 48This driver can be installed using amdgpu-pro-install script in official amd driver archive. 49 50@section AviSynth 51 52FFmpeg can read AviSynth scripts as input. To enable support, pass 53@code{--enable-avisynth} to configure after installing the headers 54provided by @url{https://github.com/AviSynth/AviSynthPlus, AviSynth+}. 55AviSynth+ can be configured to install only the headers by either 56passing @code{-DHEADERS_ONLY:bool=on} to the normal CMake-based build 57system, or by using the supplied @code{GNUmakefile}. 58 59For Windows, supported AviSynth variants are 60@url{http://avisynth.nl, AviSynth 2.6 RC1 or higher} for 32-bit builds and 61@url{http://avisynth.nl/index.php/AviSynth+, AviSynth+ r1718 or higher} for 32-bit and 64-bit builds. 62 63For Linux, macOS, and BSD, the only supported AviSynth variant is 64@url{https://github.com/AviSynth/AviSynthPlus, AviSynth+}, starting with version 3.5. 65 66@float NOTE 67In 2016, AviSynth+ added support for building with GCC. However, due to 68the eccentricities of Windows' calling conventions, 32-bit GCC builds 69of AviSynth+ are not compatible with typical 32-bit builds of FFmpeg. 70 71By default, FFmpeg assumes compatibility with 32-bit MSVC builds of 72AviSynth+ since that is the most widely-used and entrenched build 73configuration. Users can override this and enable support for 32-bit 74GCC builds of AviSynth+ by passing @code{-DAVSC_WIN32_GCC32} to 75@code{--extra-cflags} when configuring FFmpeg. 76 7764-bit builds of FFmpeg are not affected, and can use either MSVC or 78GCC builds of AviSynth+ without any special flags. 79@end float 80 81@float NOTE 82AviSynth(+) is loaded dynamically. Distributors can build FFmpeg 83with @code{--enable-avisynth}, and the binaries will work regardless 84of the end user having AviSynth installed. If/when an end user 85would like to use AviSynth scripts, then they can install AviSynth(+) 86and FFmpeg will be able to find and use it to open scripts. 87@end float 88 89@section Chromaprint 90 91FFmpeg can make use of the Chromaprint library for generating audio fingerprints. 92Pass @code{--enable-chromaprint} to configure to 93enable it. See @url{https://acoustid.org/chromaprint}. 94 95@section codec2 96 97FFmpeg can make use of the codec2 library for codec2 decoding and encoding. 98There is currently no native decoder, so libcodec2 must be used for decoding. 99 100Go to @url{http://freedv.org/}, download "Codec 2 source archive". 101Build and install using CMake. Debian users can install the libcodec2-dev package instead. 102Once libcodec2 is installed you can pass @code{--enable-libcodec2} to configure to enable it. 103 104The easiest way to use codec2 is with .c2 files, since they contain the mode information required for decoding. 105To encode such a file, use a .c2 file extension and give the libcodec2 encoder the -mode option: 106@code{ffmpeg -i input.wav -mode 700C output.c2}. 107Playback is as simple as @code{ffplay output.c2}. 108For a list of supported modes, run @code{ffmpeg -h encoder=libcodec2}. 109Raw codec2 files are also supported. 110To make sense of them the mode in use needs to be specified as a format option: 111@code{ffmpeg -f codec2raw -mode 1300 -i input.raw output.wav}. 112 113@section dav1d 114 115FFmpeg can make use of the dav1d library for AV1 video decoding. 116 117Go to @url{https://code.videolan.org/videolan/dav1d} and follow the instructions for 118installing the library. Then pass @code{--enable-libdav1d} to configure to enable it. 119 120@section davs2 121 122FFmpeg can make use of the davs2 library for AVS2-P2/IEEE1857.4 video decoding. 123 124Go to @url{https://github.com/pkuvcl/davs2} and follow the instructions for 125installing the library. Then pass @code{--enable-libdavs2} to configure to 126enable it. 127 128@float NOTE 129libdavs2 is under the GNU Public License Version 2 or later 130(see @url{http://www.gnu.org/licenses/old-licenses/gpl-2.0.html} for 131details), you must upgrade FFmpeg's license to GPL in order to use it. 132@end float 133 134@section Game Music Emu 135 136FFmpeg can make use of the Game Music Emu library to read audio from supported video game 137music file formats. Pass @code{--enable-libgme} to configure to 138enable it. See @url{https://bitbucket.org/mpyne/game-music-emu/overview}. 139 140@section Intel QuickSync Video 141 142FFmpeg can use Intel QuickSync Video (QSV) for accelerated decoding and encoding 143of multiple codecs. To use QSV, FFmpeg must be linked against the @code{libmfx} 144dispatcher, which loads the actual decoding libraries. 145 146The dispatcher is open source and can be downloaded from 147@url{https://github.com/lu-zero/mfx_dispatch.git}. FFmpeg needs to be configured 148with the @code{--enable-libmfx} option and @code{pkg-config} needs to be able to 149locate the dispatcher's @code{.pc} files. 150 151@section Kvazaar 152 153FFmpeg can make use of the Kvazaar library for HEVC encoding. 154 155Go to @url{https://github.com/ultravideo/kvazaar} and follow the 156instructions for installing the library. Then pass 157@code{--enable-libkvazaar} to configure to enable it. 158 159@section LAME 160 161FFmpeg can make use of the LAME library for MP3 encoding. 162 163Go to @url{http://lame.sourceforge.net/} and follow the 164instructions for installing the library. 165Then pass @code{--enable-libmp3lame} to configure to enable it. 166 167@section libilbc 168 169iLBC is a narrowband speech codec that has been made freely available 170by Google as part of the WebRTC project. libilbc is a packaging friendly 171copy of the iLBC codec. FFmpeg can make use of the libilbc library for 172iLBC decoding and encoding. 173 174Go to @url{https://github.com/TimothyGu/libilbc} and follow the instructions for 175installing the library. Then pass @code{--enable-libilbc} to configure to 176enable it. 177 178@section libvpx 179 180FFmpeg can make use of the libvpx library for VP8/VP9 decoding and encoding. 181 182Go to @url{http://www.webmproject.org/} and follow the instructions for 183installing the library. Then pass @code{--enable-libvpx} to configure to 184enable it. 185 186@section ModPlug 187 188FFmpeg can make use of this library, originating in Modplug-XMMS, to read from MOD-like music files. 189See @url{https://github.com/Konstanty/libmodplug}. Pass @code{--enable-libmodplug} to configure to 190enable it. 191 192@section OpenCORE, VisualOn, and Fraunhofer libraries 193 194Spun off Google Android sources, OpenCore, VisualOn and Fraunhofer 195libraries provide encoders for a number of audio codecs. 196 197@float NOTE 198OpenCORE and VisualOn libraries are under the Apache License 2.0 199(see @url{http://www.apache.org/licenses/LICENSE-2.0} for details), which is 200incompatible to the LGPL version 2.1 and GPL version 2. You have to 201upgrade FFmpeg's license to LGPL version 3 (or if you have enabled 202GPL components, GPL version 3) by passing @code{--enable-version3} to configure in 203order to use it. 204 205The license of the Fraunhofer AAC library is incompatible with the GPL. 206Therefore, for GPL builds, you have to pass @code{--enable-nonfree} to 207configure in order to use it. To the best of our knowledge, it is 208compatible with the LGPL. 209@end float 210 211@subsection OpenCORE AMR 212 213FFmpeg can make use of the OpenCORE libraries for AMR-NB 214decoding/encoding and AMR-WB decoding. 215 216Go to @url{http://sourceforge.net/projects/opencore-amr/} and follow the 217instructions for installing the libraries. 218Then pass @code{--enable-libopencore-amrnb} and/or 219@code{--enable-libopencore-amrwb} to configure to enable them. 220 221@subsection VisualOn AMR-WB encoder library 222 223FFmpeg can make use of the VisualOn AMR-WBenc library for AMR-WB encoding. 224 225Go to @url{http://sourceforge.net/projects/opencore-amr/} and follow the 226instructions for installing the library. 227Then pass @code{--enable-libvo-amrwbenc} to configure to enable it. 228 229@subsection Fraunhofer AAC library 230 231FFmpeg can make use of the Fraunhofer AAC library for AAC decoding & encoding. 232 233Go to @url{http://sourceforge.net/projects/opencore-amr/} and follow the 234instructions for installing the library. 235Then pass @code{--enable-libfdk-aac} to configure to enable it. 236 237@section OpenH264 238 239FFmpeg can make use of the OpenH264 library for H.264 decoding and encoding. 240 241Go to @url{http://www.openh264.org/} and follow the instructions for 242installing the library. Then pass @code{--enable-libopenh264} to configure to 243enable it. 244 245For decoding, this library is much more limited than the built-in decoder 246in libavcodec; currently, this library lacks support for decoding B-frames 247and some other main/high profile features. (It currently only supports 248constrained baseline profile and CABAC.) Using it is mostly useful for 249testing and for taking advantage of Cisco's patent portfolio license 250(@url{http://www.openh264.org/BINARY_LICENSE.txt}). 251 252@section OpenJPEG 253 254FFmpeg can use the OpenJPEG libraries for decoding/encoding J2K videos. Go to 255@url{http://www.openjpeg.org/} to get the libraries and follow the installation 256instructions. To enable using OpenJPEG in FFmpeg, pass @code{--enable-libopenjpeg} to 257@file{./configure}. 258 259@section rav1e 260 261FFmpeg can make use of rav1e (Rust AV1 Encoder) via its C bindings to encode videos. 262Go to @url{https://github.com/xiph/rav1e/} and follow the instructions to build 263the C library. To enable using rav1e in FFmpeg, pass @code{--enable-librav1e} 264to @file{./configure}. 265 266@section TwoLAME 267 268FFmpeg can make use of the TwoLAME library for MP2 encoding. 269 270Go to @url{http://www.twolame.org/} and follow the 271instructions for installing the library. 272Then pass @code{--enable-libtwolame} to configure to enable it. 273 274@section VapourSynth 275 276FFmpeg can read VapourSynth scripts as input. To enable support, pass 277@code{--enable-vapoursynth} to configure. Vapoursynth is detected via 278@code{pkg-config}. Versions 42 or greater supported. 279See @url{http://www.vapoursynth.com/}. 280 281Due to security concerns, Vapoursynth scripts will not 282be autodetected so the input format has to be forced. For ff* CLI tools, 283add @code{-f vapoursynth} before the input @code{-i yourscript.vpy}. 284 285@section WavPack 286 287FFmpeg can make use of the libwavpack library for WavPack encoding. 288 289Go to @url{http://www.wavpack.com/} and follow the instructions for 290installing the library. Then pass @code{--enable-libwavpack} to configure to 291enable it. 292 293@section x264 294 295FFmpeg can make use of the x264 library for H.264 encoding. 296 297Go to @url{http://www.videolan.org/developers/x264.html} and follow the 298instructions for installing the library. Then pass @code{--enable-libx264} to 299configure to enable it. 300 301@float NOTE 302x264 is under the GNU Public License Version 2 or later 303(see @url{http://www.gnu.org/licenses/old-licenses/gpl-2.0.html} for 304details), you must upgrade FFmpeg's license to GPL in order to use it. 305@end float 306 307@section x265 308 309FFmpeg can make use of the x265 library for HEVC encoding. 310 311Go to @url{http://x265.org/developers.html} and follow the instructions 312for installing the library.
