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

337 done). Added proper support for audio/video file conversion in
338 ffmpeg.
