@chapter External libraries

Libav 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 OpenCORE and VisualOn 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 with the LGPL version 2.1 and GPL version 2. You have to
upgrade Libav's license to LGPL version 3 (or if you have enabled
GPL components, GPL version 3) to use it.
@end float

@subsection OpenCORE AMR

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

instructions for installing the libraries.
Then pass @code{--enable-libopencore-amrnb} and/or
@code{--enable-libopencore-amrwb} to configure to enable them.

@subsection VisualOn AAC encoder library

Libav can make use of the VisualOn AACenc library for AAC encoding.

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

@subsection VisualOn AMR-WB encoder library

Libav 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

Libav can make use of the Fraunhofer AAC library for AAC 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

Libav 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

Libav 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 libvpx

Libav can make use of the libvpx library for VP8 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

Libav 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 OpenH264

Libav can make use of the OpenH264 library for H.264 encoding.

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.

@section x264

Libav 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 Libav's license to GPL in order to use it.
@end float

@section x265

Libav 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 Libav's license to GPL in order to use it.
@end float

@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. Libav can make use of the libilbc library for
iLBC encoding and decoding.

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

@section AviSynth

Libav can read AviSynth scripts as input. To enable support you need a
suitable @file{avisynth_c.h} header to compile against. The header as
provided by AviSynth+ is fully compatible. AviSynth 2.5 is not supported
by Libav. Once you have the appropriate header, pass
@code{--enable-avisynth} to configure to enable AviSynth support.

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.
@url{https://github.com/AviSynth/AviSynthPlus, AviSynth+'s git repository}
provides a GNU-style Makefile which can install just the headers using
@code{make install PREFIX=/install/prefix}.

@float NOTE
When using AviSynth+'s installed headers, the user must also pass
the avisynth/ include directory to @code{--extra-cflags}. For example,
if the PREFIX given to AviSynth+'s Makefile was /usr/i686-w64-mingw32,
then the correct command would be
@code{--extra-cflags="-I/usr/i686-w64-mingw32/include/avisynth"}.
@end float

For Linux and OS X, the supported AviSynth variant is
@url{https://github.com/avxsynth/avxsynth, AvxSynth}.
@file{avxsynth_c.h} is installed as part of the normal
build routine, as illustrated on
@url{https://github.com/avxsynth/avxsynth/wiki/System-Setup, AvxSynth's wiki}.
(the instructions for compiling its prerequisites are outdated, as FFMS 2.18
or higher is now needed; the list of dependencies to be downloaded from the
repositories is still the same, though).

@float NOTE
AviSynth and AvxSynth are loaded dynamically.  Distributors can build Libav
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

Libav can use Intel QuickSync Video (QSV) for accelerated encoding and decoding
of multiple codecs. To use QSV, Libav 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}. Libav 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.

@chapter Supported File Formats and Codecs

You can use the @code{-formats} and @code{-codecs} options to have an exhaustive list.

@section File Formats

Libav supports the following file formats through the @code{libavformat}
library:
