  this +codec ;) (JuanJo).
594

640
  mmx/see optimization). Enable multiple image size support in ffserver.
641
- added multi live feed support in ffserver
642

643
  external program which opens the .ffm url and writes it to another
644
  ffserver)

646
  done). Added proper support for audio/video file conversion in
