560

    
561

  this +codec ;) (JuanJo).
573
- Halfpel motion estimation after MB type selection (JuanJo)
574
- added pgm and .Y.U.V output format

578
  <lists at reserv.at>, but changed completely since we use a format
579
  instead of a protocol)
580

    
581

  (for OpenDivX) is almost complete: 8x8 MVs and rounding are
586
  missing. MSMPEG4 support is complete.
587
- added prototype MPEG-1 decoder. Only I- and P-frames handled yet (it
588
  can decode ffmpeg MPEGs :-)).

590
- fixed image polyphase bug (the bottom of some images could be
591

602
  of AVI and ASF to DIV3.
603
- added -me option to set motion estimation method
604
  (default=log). suppressed redundant -hq option.
605

606
  AVI for example)

- added timeshifting support for live feeds (option ?date=xxx in the
617
  URL)
618
- added high quality image resize code with polyphase filter (need
619
  mmx/see optimization). Enable multiple image size support in ffserver.
620
- added multi live feed support in ffserver
621
- suppressed master feature from ffserver (it should be done with an
622
  external program which opens the .ffm url and writes it to another
623
  ffserver)
624
- added preliminary support for video stream parsing (WAV and AVI half
625
  done). Added proper support for audio/video file conversion in
626
  ffmpeg.
