563

    
564

  this +codec ;) (JuanJo).
576
- Halfpel motion estimation after MB type selection (JuanJo)
577
- added pgm and .Y.U.V output format

581
  <lists at reserv.at>, but changed completely since we use a format
582
  instead of a protocol)
583

    
584

    
585

586

    
587

588
  (for OpenDivX) is almost complete: 8x8 MVs and rounding are
589
  missing. MSMPEG4 support is complete.
590
- added prototype MPEG-1 decoder. Only I- and P-frames handled yet (it
591
  can decode ffmpeg MPEGs :-)).

- added libavcodec API documentation (see apiexample.c).
593
- fixed image polyphase bug (the bottom of some images could be
594
  greenish)

605
  of AVI and ASF to DIV3.
606
- added -me option to set motion estimation method
607
  (default=log). suppressed redundant -hq option.
608

609
  AVI for example)

  multistream support to ffmpeg.
619
- added timeshifting support for live feeds (option ?date=xxx in the
620
  URL)
621
- added high quality image resize code with polyphase filter (need
622
  mmx/see optimization). Enable multiple image size support in ffserver.
623
- added multi live feed support in ffserver
624
- suppressed master feature from ffserver (it should be done with an
625
  external program which opens the .ffm url and writes it to another
626
  ffserver)
627
- added preliminary support for video stream parsing (WAV and AVI half
628
  done). Added proper support for audio/video file conversion in
629
  ffmpeg.
630
