293 AVI for example).
294- fixed -an option.
295- improved dct_quantize speed.
296- factorized some motion estimation code.

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.

331- added 'high quality' mode which use motion vectors. It can be used in
332 real time at low resolution.
333- fixed rounding problems which caused quality problems at high
334 bitrates and large gop size.
336version 0.3.2: small fixes
