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

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