@chapter External libraries

Libav can be hooked up with a number of external libraries to add support
15
for more formats. None of them are used by default, their use has to be
16 17
explicitly requested by passing the appropriate flags to
@command{./configure}.

@section OpenH264

100
Libav can make use of the OpenH264 library for H.264 encoding and decoding.
101 102 103 104 105

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.

106 107 108 109 110 111 112
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}).

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.

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

@section kvazaar

Libav 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. 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.

160 161 162 163 164 165 166 167 168
@section libhdcd

Libav can make use of the libhdcd library for High Definition Compatible
Digital (HDCD) decoding via the @code{hdcd} filter.

Go to @url{https://github.com/bp0/libhdcd} and follow the instructions for
installing the library. Then pass @code{--enable-libhdcd} to configure to
enable it.

169 170 171
@section AviSynth

Libav can read AviSynth scripts as input. To enable support you need a
172 173 174 175
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.
176 177

For Windows, supported AviSynth variants are
178 179
@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.
180 181 182 183 184 185 186 187 188 189 190
@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
191 192 193 194 195 196 197 198 199

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).
200

201 202 203 204 205 206
@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

208 209 210 211 212 213 214 215 216 217 218
@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.
