Decoders:

• Intel Music Coder audio decoding via lavc
• Monkey Audio audio decoding via lavc
• Fraps v2/v4 video decoding via lavc
• Video game codecs: 4XM audio, Electronic Arts ADPCM audio, Delphine CIN audio and video, Interplay DPCM audio, Sierra VMD video, Tiertex SEQ video, Westwood IMA ADPCM audio, XAN wc3 video, Id CIN video, Interplay video, XAN ADPCM audio, Westwood SND1 audio, Feeble Files DXA video, THP audio and video, Renderware TeXture Dictionary video, Bethesda Software VID video via lavc

Demuxers:

• Implemented switch_video and switch_program consistently with switch_audio (default keys are "_" and TAB, respectively). For the time being program switching is only available in TS streams handled by demux_ts.c (not libavformat), while video switching is also handled by demux_lavf.c and demux_avi.c.

• SMIL playlist over Real RTSP
• support H.263-2000 over RTSP (live555)
• fix AAC-LATM over RTSP (live555)

• native NUT demuxer updated to spec
• native NUT muxer
• NUT muxing and demuxing support via libnut
• WMA encoder
• fix MJPEG-B on big-endian systems

• Atrac 3 audio decoder
• MPEG-1/2 speedups
• RoQ muxer, video and audio encoder
• QTRLE encoder
• AC-3 decoder
• Matroska muxer
• Monkey's Audio demuxer and decoder
• Flac encoder and decoder speedups
• AMV demuxer and audio/video decoder

libmpeg2:

• iWMMXt-accelerated DCT and motion compensation for ARM processors

Filters:

• vf_geq speed-ups
• vf_yadif green frame fixed
• fix af_pan when switching audio streams
• add audio left/right balance feature to af_pan

MEncoder:

• write to output streams (currently only file:// and smb://)
• support -ffourcc with -of lavf
• removed B-frame warning message
• fixed bugs that would corrupt headers in the video stream when using telecining and not patch the TFF flag correctly

Ports:

• Complete Intel Mac support

• Blackfin optimizations

Drivers:

• ALSA audio output now sets the non-audio bit for AC3 passthrough even if the user-specified default device name tries to clear it
• fixed internal VIDIX in Solaris/x86, also auto-enabled
• rework of internal VIDIX, now a fully static library with builtin drivers
• updated VIDIX ATI drivers
• Sun XVR-100 video output driver

Others:
