  (for OpenDivX) is almost complete: 8x8 MVs and rounding are

  URL) 
- added high quality image resize code with polyphase filter (need 
  mmx/see optimisation). Enable multiple image size support in ffserver.

- suppressed master feature from ffserver (it should be done with an 
  external program which opens the .ffm url and writes it to another 
  ffserver) 
- added preliminary support for video stream parsing (WAV and AVI half 
  done). Added proper support for audio/video file conversion in 
  ffmpeg.
