12@chapter External libraries
14Libav can be hooked up with a number of external libraries to add support
15for more formats. None of them are used by default, their use has to be
16explicitly requested by passing the appropriate flags to
19@section OpenCORE and VisualOn libraries
21Spun off Google Android sources, OpenCore, VisualOn and Fraunhofer
22libraries provide encoders for a number of audio codecs.
24@float NOTE
25OpenCORE and VisualOn libraries are under the Apache License 2.0
26(see @url{} for details), which is
27incompatible with the LGPL version 2.1 and GPL version 2. You have to
28upgrade Libav's license to LGPL version 3 (or if you have enabled
29GPL components, GPL version 3) to use it.
30@end float
32@subsection OpenCORE AMR
34Libav can make use of the OpenCORE libraries for AMR-NB
35decoding/encoding and AMR-WB decoding.
37Go to @url{} and follow the
38instructions for installing the libraries.
39Then pass @code{--enable-libopencore-amrnb} and/or
40@code{--enable-libopencore-amrwb} to configure to enable them.
42@subsection VisualOn AAC encoder library
44Libav can make use of the VisualOn AACenc library for AAC encoding.
46Go to @url{} and follow the
47instructions for installing the library.
48Then pass @code{--enable-libvo-aacenc} to configure to enable it.
50@subsection VisualOn AMR-WB encoder library
52Libav can make use of the VisualOn AMR-WBenc library for AMR-WB encoding.
54Go to @url{} and follow the
55instructions for installing the library.
56Then pass @code{--enable-libvo-amrwbenc} to configure to enable it.
58@subsection Fraunhofer AAC library
60Libav can make use of the Fraunhofer AAC library for AAC encoding.
62Go to @url{} and follow the
63instructions for installing the library.
64Then pass @code{--enable-libfdk-aac} to configure to enable it.
66@section LAME
68Libav can make use of the LAME library for MP3 encoding.
70Go to @url{} and follow the
71instructions for installing the library.
72Then pass @code{--enable-libmp3lame} to configure to enable it.
74@section TwoLAME
76Libav can make use of the TwoLAME library for MP2 encoding.
78Go to @url{} and follow the
79instructions for installing the library.
80Then pass @code{--enable-libtwolame} to configure to enable it.
82@section libvpx
84Libav can make use of the libvpx library for VP8 encoding.
86Go to @url{} and follow the instructions for
87installing the library. Then pass @code{--enable-libvpx} to configure to
88enable it.
90@section libwavpack
92Libav can make use of the libwavpack library for WavPack encoding.
94Go to @url{} and follow the instructions for
95installing the library. Then pass @code{--enable-libwavpack} to configure to
96enable it.
98@section libxavs
100Libav can make use of the libxavs library for Xavs encoding.
102Go to @url{} and follow the instructions for
103installing the library. Then pass @code{--enable-libxavs} to configure to
104enable it.
106@section OpenH264
108Libav can make use of the OpenH264 library for H.264 encoding and decoding.
110Go to @url{} and follow the instructions for
111installing the library. Then pass @code{--enable-libopenh264} to configure to
112enable it.
114For decoding, this library is much more limited than the built-in decoder
115in libavcodec; currently, this library lacks support for decoding B-frames
116and some other main/high profile features. (It currently only supports
117constrained baseline profile and CABAC.) Using it is mostly useful for
118testing and for taking advantage of Cisco's patent portfolio license
121@section x264
123Libav can make use of the x264 library for H.264 encoding.
125Go to @url{} and follow the
126instructions for installing the library. Then pass @code{--enable-libx264} to
127configure to enable it.
129@float NOTE
130x264 is under the GNU Public License Version 2 or later
131(see @url{} for
132details), you must upgrade Libav's license to GPL in order to use it.
133@end float
135@section x265
137Libav can make use of the x265 library for HEVC encoding.
139Go to @url{} and follow the instructions
140for installing the library. Then pass @code{--enable-libx265} to configure
141to enable it.
143@float note
144x265 is under the GNU Public License Version 2 or later
145(see @url{} for
146details), you must upgrade Libav's license to GPL in order to use it.
147@end float
149@section kvazaar
151Libav can make use of the kvazaar library for HEVC encoding.
153Go to @url{} and follow the
154instructions for installing the library. Then pass
155@code{--enable-libkvazaar} to configure to enable it.
157@section libilbc
159iLBC is a narrowband speech codec that has been made freely available
160by Google as part of the WebRTC project. libilbc is a packaging friendly
161copy of the iLBC codec. Libav can make use of the libilbc library for
162iLBC encoding and decoding.
164Go to @url{} and follow the instructions for
165installing the library. Then pass @code{--enable-libilbc} to configure to
166enable it.
168@section libhdcd
170Libav can make use of the libhdcd library for High Definition Compatible
171Digital (HDCD) decoding via the @code{hdcd} filter.
173Go to @url{} and follow the instructions for
174installing the library. Then pass @code{--enable-libhdcd} to configure to
175enable it.
177@section AviSynth
179Libav can read AviSynth scripts as input. To enable support you need a
180suitable @file{avisynth_c.h} header to compile against. The header as
181provided by AviSynth+ is fully compatible. AviSynth 2.5 is not supported
182by Libav. Once you have the appropriate header, pass
183@code{--enable-avisynth} to configure to enable AviSynth support.
185For Windows, supported AviSynth variants are
186@url{, AviSynth 2.6 RC1 or higher} for 32-bit builds and
187@url{, AviSynth+ r1718 or higher} for 32-bit and 64-bit builds.
188@url{, AviSynth+'s git repository}
189provides a GNU-style Makefile which can install just the headers using
190@code{make install PREFIX=/install/prefix}.
192@float NOTE
193There is currently a regression in AviSynth+'s @code{capi.h} header as of
194October 2016, which interferes with the ability for builds of Libav to use
195MSVC-built binaries of AviSynth. Until this is resolved, you can make sure
196a known good version is installed by checking out a version from before
197the regression occurred:
199@code{git clone -b MT git:// @*
200cd AviSynthPlus @*
201git checkout -b oldheader b4f292b4dbfad149697fb65c6a037bb3810813f9 @*
202make install PREFIX=/install/prefix}
203@end float
205@float NOTE
206When using AviSynth+'s installed headers, the user must also pass
207the avisynth/ include directory to @code{--extra-cflags}. For example,
208if the PREFIX given to AviSynth+'s Makefile was /usr/i686-w64-mingw32,
209then the correct command would be
211@end float
213For Linux and OS X, the supported AviSynth variant is
214@url{, AvxSynth}.
215@file{avxsynth_c.h} is installed as part of the normal
216build routine, as illustrated on
217@url{, AvxSynth's wiki}.
218(the instructions for compiling its prerequisites are outdated, as FFMS 2.18
219or higher is now needed; the list of dependencies to be downloaded from the
220repositories is still the same, though).
222@float NOTE
223AviSynth and AvxSynth are loaded dynamically. Distributors can build Libav
224with @code{--enable-avisynth}, and the binaries will work regardless of the
225end user having AviSynth or AvxSynth installed - they'll only need to be
226installed to use AviSynth scripts (obviously).
227@end float
229@section Intel QuickSync Video
231Libav can use Intel QuickSync Video (QSV) for accelerated encoding and decoding
232of multiple codecs. To use QSV, Libav must be linked against the @code{libmfx}
233dispatcher, which loads the actual decoding libraries.
235The dispatcher is open source and can be downloaded from
236@url{}. Libav needs to be configured
237with the @code{--enable-libmfx} option and @code{pkg-config} needs to be able to
238locate the dispatcher's @code{.pc} files.
240@chapter Supported File Formats and Codecs
242You can use the @code{-formats} and @code{-codecs} options to have an exhaustive list.
244@section File Formats
