284- improved dct_quantize speed.
285- factorized some motion estimation code.

294 mmx/see optimisation). Enable multiple image size support in ffserver.
295- added multi live feed support in ffserver.
296- suppressed master feature from ffserver (it should be done with an
297 external program which opens the .ffm url and writes it to another
298 ffserver).
299- added preliminary support for video stream parsing (wav and avi half
300 done). Added proper support for audio/video file convertion in
301 ffmpeg.
302- added preliminary support for video file sending from ffserver.

322- fixed rounding problems which caused quality problems at high
323 bitrates and large gop size.
325version 0.3.2: small fixes
327- asf fixes
328- put_seek bug fix
