@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.
