306 mmx/see optimisation). Enable multiple image size support in ffserver.
307- added multi live feed support in ffserver.
308- suppressed master feature from ffserver (it should be done with an
309 external program which opens the .ffm url and writes it to another
310 ffserver).

312 done). Added proper support for audio/video file convertion in
313 ffmpeg.
