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

284- improved dct_quantize speed.
285- factorized some motion estimation code.
286
287version 0.4.0:

290 stream support to ffmpeg.
291- added timeshifting support for live feeds (option ?date=xxx in the
292 URL).
293- added high quality image resize code with polyphase filter (need
294 mmx/see optimisation). Enable multiple image size support in ffserver.
295- added multi live feed support in ffserver.
296- suppressed master feature from ffserver (it should be done with an
297 external program which opens the .ffm url and writes it to another
298 ffserver).
299- added preliminary support for video stream parsing (wav and avi half
300 done). Added proper support for audio/video file convertion in
301 ffmpeg.
302- added preliminary support for video file sending from ffserver.
