@subsection OpenCORE AMR
-Libav can make use of the OpenCORE libraries for AMR-NB
+FFmpeg 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

-Libav can make use of the VisualOn AMR-WBenc library for AMR-WB encoding.
+FFmpeg can make use of the VisualOn AMR-WBenc library for AMR-WB encoding.

@section LAME
-Libav can make use of the LAME library for MP3 encoding.
+FFmpeg 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.
@section TwoLAME

+FFmpeg 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 libcodec2 / codec2 general
+
+FFmpeg can make use of libcodec2 for codec2 encoding and decoding.
+There is currently no native decoder, so libcodec2 must be used for decoding.
+
+Go to @url{http://freedv.org/}, download "Codec 2 source archive".
+Build and install using CMake. Debian users can install the libcodec2-dev package instead.
+Once libcodec2 is installed you can pass @code{--enable-libcodec2} to configure to enable it.
+
+The easiest way to use codec2 is with .c2 files, since they contain the mode information required for decoding.
+To encode such a file, use a .c2 file extension and give the libcodec2 encoder the -mode option:
+@code{ffmpeg -i input.wav -mode 700C output.c2}.
+Playback is as simple as @code{ffplay output.c2}.
+For a list of supported modes, run @code{ffmpeg -h encoder=libcodec2}.
+Raw codec2 files are also supported.
+To make sense of them the mode in use needs to be specified as a format option:
+@code{ffmpeg -f codec2raw -mode 1300 -i input.raw output.wav}.
+
@section libvpx
-Libav can make use of the libvpx library for VP8 encoding.
+FFmpeg can make use of the libvpx library for VP8/VP9 encoding.

@float NOTE
-When using AviSynth+'s installed headers, the user must also pass
