295- improved dct_quantize speed.
296- factorized some motion estimation code.
297

305 mmx/see optimisation). Enable multiple image size support in ffserver.
306- added multi live feed support in ffserver.
307- suppressed master feature from ffserver (it should be done with an
308 external program which opens the .ffm url and writes it to another
309 ffserver).
310- added preliminary support for video stream parsing (wav and avi half
311 done). Added proper support for audio/video file convertion in
312 ffmpeg.
313- added preliminary support for video file sending from ffserver.
314- redesigning I/O subsystem : now using URL based input and output
315 (see avio.h).
