FB
249 instead of a protocol).
250

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

274 AVI for example).
275- fixed -an option.
276- improved dct_quantize speed.
277- factorized some motion estimation code.
278
279version 0.4.0:

282 stream support to ffmpeg.
283- added timeshifting support for live feeds (option ?date=xxx in the
284 URL).
285- added high quality image resize code with polyphase filter (need
286 mmx/see optimisation). Enable multiple image size support in ffserver.
287- added multi live feed support in ffserver.
288- suppressed master feature from ffserver (it should be done with an
289 external program which opens the .ffm url and writes it to another
290 ffserver).
291- added preliminary support for video stream parsing (wav and avi half
292 done). Added proper support for audio/video file convertion in
293 ffmpeg.
294- added preliminary support for video file sending from ffserver.
295- redesigning I/O subsystem : now using URL based input and output
296 (see avio.h).
