12 @chapter External libraries
14 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 explicitly requested by passing the appropriate flags to
17 @command{./configure}.
19 @section OpenCORE and VisualOn libraries
21 Spun off Google Android sources, OpenCore, VisualOn and Fraunhofer
22 libraries provide encoders for a number of audio codecs.
25 OpenCORE and VisualOn libraries are under the Apache License 2.0
26 (see @url{http://www.apache.org/licenses/LICENSE-2.0} for details), which is
27 incompatible with the LGPL version 2.1 and GPL version 2. You have to
28 upgrade Libav's license to LGPL version 3 (or if you have enabled
29 GPL components, GPL version 3) to use it.
32 @subsection OpenCORE AMR
34 Libav can make use of the OpenCORE libraries for AMR-NB
35 decoding/encoding and AMR-WB decoding.
37 Go to @url{http://sourceforge.net/projects/opencore-amr/} and follow the
38 instructions for installing the libraries.
39 Then pass @code{--enable-libopencore-amrnb} and/or
40 @code{--enable-libopencore-amrwb} to configure to enable them.
42 @subsection VisualOn AAC encoder library
44 Libav can make use of the VisualOn AACenc library for AAC encoding.
46 Go to @url{http://sourceforge.net/projects/opencore-amr/} and follow the
47 instructions for installing the library.
48 Then pass @code{--enable-libvo-aacenc} to configure to enable it.
50 @subsection VisualOn AMR-WB encoder library
52 Libav can make use of the VisualOn AMR-WBenc library for AMR-WB encoding.
54 Go to @url{http://sourceforge.net/projects/opencore-amr/} and follow the
55 instructions for installing the library.
56 Then pass @code{--enable-libvo-amrwbenc} to configure to enable it.
58 @subsection Fraunhofer AAC library
60 Libav can make use of the Fraunhofer AAC library for AAC encoding.
62 Go to @url{http://sourceforge.net/projects/opencore-amr/} and follow the
63 instructions for installing the library.
64 Then pass @code{--enable-libfdk-aac} to configure to enable it.
68 Libav can make use of the LAME library for MP3 encoding.
70 Go to @url{http://lame.sourceforge.net/} and follow the
71 instructions for installing the library.
72 Then pass @code{--enable-libmp3lame} to configure to enable it.
76 Libav can make use of the libvpx library for VP8 encoding.
78 Go to @url{http://www.webmproject.org/} and follow the instructions for
79 installing the library. Then pass @code{--enable-libvpx} to configure to
84 Libav can make use of the libwavpack library for WavPack encoding.
86 Go to @url{http://www.wavpack.com/} and follow the instructions for
87 installing the library. Then pass @code{--enable-libwavpack} to configure to
92 Libav can make use of the x264 library for H.264 encoding.
94 Go to @url{http://www.videolan.org/developers/x264.html} and follow the
95 instructions for installing the library. Then pass @code{--enable-libx264} to
96 configure to enable it.
