@chapter external libraries
FFmpeg can be hooked up with a number of external libraries to add support
for more formats.
@section AMR
AMR comes in two different flavors, WB and NB. FFmpeg can make use of the
AMR WB (floating-point mode) and the AMR NB (both floating-point and
fixed-point mode) reference decoders and encoders.
@itemize
@item For AMR WB floating-point download TS26.204 V5.1.0 from
@url{http://www.3gpp.org/ftp/Specs/archive/26_series/26.204/26204-510.zip}
and extract the source to @file{libavcodec/amrwb_float/}.
@item For AMR NB floating-point download TS26.104 REL-5 V5.1.0 from
@url{http://www.3gpp.org/ftp/Specs/archive/26_series/26.104/26104-510.zip}
and extract the source to @file{libavcodec/amr_float/}.
If you try this on Alpha, you may need to change @code{Word32} to
@code{int} in @file{amr/typedef.h}.
@item For AMR NB fixed-point download TS26.073 REL-5 V5.1.0 from
@url{http://www.3gpp.org/ftp/Specs/archive/26_series/26.073/26073-510.zip}
and extract the source to @file{libavcodec/amr}.
You must also add @code{-DMMS_IO} and remove @code{-pedantic-errors}
to/from @code{CFLAGS} in @file{libavcodec/amr/makefile}, i.e.
``@code{CFLAGS = -Wall -I. \$(CFLAGS_\$(MODE)) -D\$(VAD) -DMMS_IO}''.
