264 can decode ffmpeg mpegs :-)).
265- added libavcodec API documentation (see apiexample.c).

283- improved dct_quantize speed.
284- factorized some motion estimation code.
285
286version 0.4.0:

289 stream support to ffmpeg.
290- added timeshifting support for live feeds (option ?date=xxx in the
291 URL).

293 mmx/see optimisation). Enable multiple image size support in ffserver.
294- added multi live feed support in ffserver.
295- suppressed master feature from ffserver (it should be done with an
296 external program which opens the .ffm url and writes it to another
297 ffserver).
298- added preliminary support for video stream parsing (wav and avi half
299 done). Added proper support for audio/video file convertion in
300 ffmpeg.
301- added preliminary support for video file sending from ffserver.
302- redesigning I/O subsystem : now using URL based input and output
303 (see avio.h).
