  this +codec ;) (JuanJo).
579
- Halfpel motion estimation after MB type selection (JuanJo)
580
- added pgm and .Y.U.V output format

584
  <lists at reserv.at>, but changed completely since we use a format
585
  instead of a protocol)
586

    
587

    
588

  (for OpenDivX) is almost complete: 8x8 MVs and rounding are
592
  missing. MSMPEG4 support is complete.
593
- added prototype MPEG-1 decoder. Only I- and P-frames handled yet (it
594
  can decode ffmpeg MPEGs :-)).

- added libavcodec API documentation (see apiexample.c).
596
- fixed image polyphase bug (the bottom of some images could be
597

608
  of AVI and ASF to DIV3.
609
- added -me option to set motion estimation method
610
  (default=log). suppressed redundant -hq option.

612
  AVI for example)

  multistream support to ffmpeg.
622
- added timeshifting support for live feeds (option ?date=xxx in the
623
  URL)
624
- added high quality image resize code with polyphase filter (need
625
  mmx/see optimization). Enable multiple image size support in ffserver.
626
- added multi live feed support in ffserver
627
- suppressed master feature from ffserver (it should be done with an
628
  external program which opens the .ffm url and writes it to another
629
  ffserver)
630
- added preliminary support for video stream parsing (WAV and AVI half
631
  done). Added proper support for audio/video file conversion in
632
  ffmpeg.
