287- improved dct_quantize speed.
288- factorized some motion estimation code.

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

323- added 'high quality' mode which use motion vectors. It can be used in
324 real time at low resolution.
325- fixed rounding problems which caused quality problems at high
326 bitrates and large gop size.
