311 mmx/see optimisation). Enable multiple image size support in ffserver.
312- added multi live feed support in ffserver.
313- suppressed master feature from ffserver (it should be done with an
314 external program which opens the .ffm url and writes it to another
315 ffserver).
316- added preliminary support for video stream parsing (wav and avi half
317 done). Added proper support for audio/video file convertion in
318 ffmpeg.
319- added preliminary support for video file sending from ffserver.
