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