Project Description
FFmpeg is a complete, cross-platform solution to record, convert and stream audio and video. It includes libavcodec - the leading audio/video codec library.
As always, check the main FFmpeg doc for a complete feature list, and the Changelog for recent changes.

The FFmpeg project would like to recognize and thank the people at Picsearch for their help improving FFmpeg recently. The Picsearch team makes extensive use of FFmpeg and provided feedback to FFmpeg in the form of thousands of files that either crash FFmpeg or use unsupported/unknown codecs. The FFmpeg development team is putting this information to work in order to improve FFmpeg for everyone.
We know that there are other organizations using FFmpeg on a large scale to process diverse input types. The FFmpeg team invites those organizations to provide similar feedback about problems encountered in the wild.

A bunch of new formats have recently been added to FFmpeg, namely a QCELP/PureVoice speech decoder, a floating point PCM decoder and encoder, a Nellymoser ASAO encoder, an Electronic Arts TGQ decoder, Speex decoding via libspeex, an MXF muxer, an ASS/SSA subtitle demuxer and muxer and our AC-3 decoder has been extended with E-AC-3 support. Last but not least we now have a decoder for RealVideo 4.0.

FFmpeg is undergoing major changes in its API/ABI. The last valid revision for libavcodec version 51 is r15261.
August 21, 2008
The AAC decoder from FFmpeg Summer of Code 2006 has finally been cleaned up and is now in FFmpeg trunk. It supports Main and Low Complexity profile AAC but does not yet support HE AAC v1 (LC + SBR) or v2 (LC + SBR + PS), though implementation of this support is underway. It is considerably faster than FAAD and you should expect further performance improvements and bug fixes in the coming weeks.
Also, FFmpeg now has floating point PCM support and supports MLP/TrueHD decoding (FFmpeg SoC 2008 should bring us an encoder), Apple Lossless Audio encoding (FFmpeg SoC 2008) MVI demuxing and Motion Pixels Video decoding, D-Cinema audio muxing, Electronic Arts CMV and TGV decoding and MAXIS EA XA demuxing/decoding.

UAB "DKD" (dkd.lt) have released a Nellymoser ASAO compatible decoder and encoder under the LGPL. This will aid the development of a native encoder in FFmpeg, and right now a GSoC student is working hard on just that task. A great thanks to UAB "DKD" for this contribution to the FFmpeg community.

We have added an Oma demuxer, the QuickTime variant of an IMA ADPCM encoder, a VFW grabber, an iPod/iPhone-compatible MP4 muxer, a Mimic decoder, an MSN TCP Webcam stream demuxer as well as demuxers and decoders for the following fringe formats: RL2, IFF, 8SVX, BFI.
February 7, 2008
We have added Ogg and AVM2 (Flash 9) SWF muxers, TechnoTrend PVA and Linux Media Labs MPEG-4 (LMLM4) demuxers, PC Paintbrush PCX and Sun Rasterfile decoders.
November 11, 2007
FFmpeg now supports XIntra8 frames, meaning that finally all WMV2 samples and some WMV3 samples that showed blocky color artifacts can be decoded correctly.
October 22, 2007
Beam Software SIFF demuxer and video decoder support added.
October 15, 2007

October 9, 2007
Apart from a DNxHD encoder, PAFF decoding support for H.264 was committed to SVN.
September 29, 2007
AMV audio and video decoding has arrived.
September 13, 2007
In about half a year of work since the last update we have added among other things: DXA and Monkey's Audio demuxer and decoder, DNxHD, Atrac3 and AC-3 decoders, QTRLE encoder, NUT and Matroska muxers.
