@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.
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 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 in
classic AviSynth's CVS repository is not compatible as it has not been
updated to support AviSynth 2.6. 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} for 32-bit builds and
@url{http://avs-plus.net, AviSynth+ 0.1} for 32-bit and 64-bit builds.
The necessary @file{avisynth_c.h} header is the variant in the @file{extras/}
directory of the @url{https://www.videolan.org/developers/x264.html, x264}
source tree. For convenience, this header is also available from a
@url{https://github.com/qyot27/avisynth_headers, temporary repository}
along with an installation routine.
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
@chapter Supported File Formats and Codecs
You can use the @code{-formats} and @code{-codecs} options to have an exhaustive list.
