There is ongoing work to implement the ACELP codecs in ffmpeg, this includes AMR, G.729, and RealAudio SIPR. This is quite a large project as there are many variants of this codec.

The current (incomplete) code is available in the ffmpeg svn: http://svn.mplayerhq.hu/ffmpeg/trunk/libavcodec/ The files are g729* and acelp* The work from the Summer of Code project is in http://svn.mplayerhq.hu/soc/amr/

Contributors are welcome to submit patches to the ffmpeg-devel mailing list. Those who wish to contribute may want to start by debugging some of the existing patches which are listed on the ffmpeg wiki at http://wiki.multimedia.cx/index.php?title=Interesting_Patches

It is possible to compile and link ffmpeg against the 3GPP reference code (libamr). This library does not have an appropriate open-source license, and will not be included in debian or ubuntu, so please don't ask.
