@chapter 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
@command{./configure}.

@section Alliance for Open Media libaom

FFmpeg can make use of the libaom library for AV1 decoding.

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

@section OpenJPEG

FFmpeg can use the OpenJPEG libraries for encoding/decoding J2K videos.  Go to
@url{http://www.openjpeg.org/} to get the libraries and follow the installation
instructions.  To enable using OpenJPEG in FFmpeg, pass @code{--enable-libopenjpeg} to
@file{./configure}.


@section OpenCORE, VisualOn, and Fraunhofer libraries

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

@float NOTE
OpenCORE and VisualOn libraries are under the Apache License 2.0
(see @url{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 @code{--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 @code{--enable-nonfree} to
configure in order to use it. To the best of our knowledge, it is
compatible with the LGPL.
@end float

@subsection OpenCORE AMR

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

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

@subsection VisualOn AMR-WB encoder library

FFmpeg can make use of the VisualOn AMR-WBenc library for AMR-WB encoding.

Go to @url{http://sourceforge.net/projects/opencore-amr/} and follow the
instructions for installing the library.
Then pass @code{--enable-libvo-amrwbenc} to configure to enable it.

@subsection Fraunhofer AAC library

FFmpeg can make use of the Fraunhofer AAC library for AAC decoding & encoding.

Go to @url{http://sourceforge.net/projects/opencore-amr/} and follow the
instructions for installing the library.
Then pass @code{--enable-libfdk-aac} to configure to enable it.

@section LAME

FFmpeg can make use of the LAME library for MP3 encoding.

Go to @url{http://lame.sourceforge.net/} and follow the
instructions for installing the library.
Then pass @code{--enable-libmp3lame} to configure to enable it.

@section TwoLAME

FFmpeg can make use of the TwoLAME library for MP2 encoding.

Go to @url{http://www.twolame.org/} and follow the
instructions for installing the library.
Then pass @code{--enable-libtwolame} to configure to enable it.

@section libcodec2 / codec2 general

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

Go to @url{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 @code{--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:
@code{ffmpeg -i input.wav -mode 700C output.c2}.
Playback is as simple as @code{ffplay output.c2}.
For a list of supported modes, run @code{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:
@code{ffmpeg -f codec2raw -mode 1300 -i input.raw output.wav}.

@section libvpx

FFmpeg can make use of the libvpx library for VP8/VP9 encoding.

Go to @url{http://www.webmproject.org/} and follow the instructions for
installing the library. Then pass @code{--enable-libvpx} to configure to
enable it.

@section libwavpack

FFmpeg can make use of the libwavpack library for WavPack encoding.

Go to @url{http://www.wavpack.com/} and follow the instructions for
installing the library. Then pass @code{--enable-libwavpack} to configure to
enable it.

@section libxavs

FFmpeg can make use of the libxavs library for Xavs encoding.

Go to @url{http://xavs.sf.net/} and follow the instructions for
installing the library. Then pass @code{--enable-libxavs} to configure to
enable it.

@section OpenH264

FFmpeg can make use of the OpenH264 library for H.264 encoding and decoding.

Go to @url{http://www.openh264.org/} and follow the instructions for
installing the library. Then pass @code{--enable-libopenh264} to configure to
enable it.

For decoding, this library is much more limited than the built-in decoder
in libavcodec; currently, this library lacks support for decoding B-frames
and some other main/high profile features. (It currently only supports
constrained baseline profile and CABAC.) Using it is mostly useful for
testing and for taking advantage of Cisco's patent portfolio license
(@url{http://www.openh264.org/BINARY_LICENSE.txt}).

@section x264

FFmpeg can make use of the x264 library for H.264 encoding.

Go to @url{http://www.videolan.org/developers/x264.html} and follow the
instructions for installing the library. Then pass @code{--enable-libx264} to
configure to enable it.

@float NOTE
x264 is under the GNU Public License Version 2 or later
(see @url{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.
@end float

@section x265

FFmpeg can make use of the x265 library for HEVC encoding.

Go to @url{http://x265.org/developers.html} and follow the instructions
for installing the library. Then pass @code{--enable-libx265} to configure
to enable it.

@float NOTE
x265 is under the GNU Public License Version 2 or later
(see @url{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.
@end float

@section kvazaar

FFmpeg can make use of the kvazaar library for HEVC encoding.

Go to @url{https://github.com/ultravideo/kvazaar} and follow the
instructions for installing the library. Then pass
@code{--enable-libkvazaar} to configure to enable it.

@section libilbc

iLBC is a narrowband speech codec that has been made freely available
by Google as part of the WebRTC project. libilbc is a packaging friendly
copy of the iLBC codec. FFmpeg can make use of the libilbc library for
iLBC encoding and decoding.

Go to @url{https://github.com/TimothyGu/libilbc} and follow the instructions for
installing the library. Then pass @code{--enable-libilbc} to configure to
enable it.

@section libzvbi

libzvbi is a VBI decoding library which can be used by FFmpeg to decode DVB
teletext pages and DVB teletext subtitles.

Go to @url{http://sourceforge.net/projects/zapping/} and follow the instructions for
installing the library. Then pass @code{--enable-libzvbi} to configure to
enable it.

@section AviSynth

FFmpeg can read AviSynth scripts as input. To enable support, pass
@code{--enable-avisynth} to configure.  The correct headers are
included in compat/avisynth/, which allows the user to enable support
without needing to search for these headers themselves.

For Windows, supported AviSynth variants are
@url{http://avisynth.nl, AviSynth 2.6 RC1 or higher} for 32-bit builds and
@url{http://avs-plus.net, AviSynth+ r1718 or higher} for 32-bit and 64-bit builds.

For Linux and OS X, the supported AviSynth variant is
@url{https://github.com/avxsynth/avxsynth, AvxSynth}.

@float NOTE
There is currently a regression in AviSynth+'s @code{capi.h} header as of
October 2016, which interferes with the ability for builds of FFmpeg to use
MSVC-built binaries of AviSynth. Until this is resolved, you can make sure
a known good version is installed by checking out a version from before
the regression occurred:

@code{git clone -b MT git://github.com/AviSynth/AviSynthPlus.git @*
cd AviSynthPlus @*
git checkout -b oldheader b4f292b4dbfad149697fb65c6a037bb3810813f9 @*
make install PREFIX=/install/prefix}
@end float

@float NOTE
AviSynth and AvxSynth are loaded dynamically.  Distributors can build FFmpeg
with @code{--enable-avisynth}, and the binaries will work regardless of the
end user having AviSynth or AvxSynth installed - they'll only need to be
installed to use AviSynth scripts (obviously).
@end float

@section Intel QuickSync Video

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

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

@section AMD VCE

FFmpeg can use the AMD Advanced Media Framework library for accelerated H.264
and HEVC encoding on VCE enabled hardware under Windows.

To enable support you must obtain the AMF framework header files from
@url{https://github.com/GPUOpen-LibrariesAndSDKs/AMF.git}.

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