FB
266 instead of a protocol).
267

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

293- improved dct_quantize speed.
294- factorized some motion estimation code.
295
296version 0.4.0:

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