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