Since the release of FFmpeg 0.5
last year there hasn't been much information about this media project publicized beyond VDPAU MPEG-4 ASP acceleration
and other features, but today there is a new announcement from this free software project.
The FFmpeg project has accomplished now work on the Indeo 5 video decoder as well as the audio decoders for AMR-NB, Sipro, MPEG-4 ALS and WMA Voice, complete support for Bink, CDG and IFF PBM/ILBM bitmaps, an RTSP muxer, Bluray (PGS) subtitle support, a protocol for file concatenation, and the ffprobe tool for extracting information from multimedia files.
The announcement can be found on the Ffmpeg web-site
