FB
267 instead of a protocol).
268

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

294- improved dct_quantize speed.
295- factorized some motion estimation code.
296

300 stream support to ffmpeg.
301- added timeshifting support for live feeds (option ?date=xxx in the
302 URL).
303- added high quality image resize code with polyphase filter (need
304 mmx/see optimisation). Enable multiple image size support in ffserver.
305- added multi live feed support in ffserver.
306- suppressed master feature from ffserver (it should be done with an
307 external program which opens the .ffm url and writes it to another
308 ffserver).
309- added preliminary support for video stream parsing (wav and avi half
310 done). Added proper support for audio/video file convertion in
311 ffmpeg.
312- added preliminary support for video file sending from ffserver.
313- redesigning I/O subsystem : now using URL based input and output
314 (see avio.h).
