306 mmx/see optimisation). Enable multiple image size support in ffserver.
307 - added multi live feed support in ffserver.

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.
314 - added preliminary support for video file sending from ffserver.
