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