556

    
557
version 0.4.3:
558

  this +codec ;) (JuanJo).
569
- Halfpel motion estimation after MB type selection (JuanJo)
570
- added pgm and .Y.U.V output format

574
  <lists at reserv.at>, but changed completely since we use a format
575
  instead of a protocol)
576

    
577

    
578

579

    
580

581
  (for OpenDivX) is almost complete: 8x8 MVs and rounding are
582
  missing. MSMPEG4 support is complete.
583
- added prototype MPEG-1 decoder. Only I- and P-frames handled yet (it
584
  can decode ffmpeg MPEGs :-)).
585
- added libavcodec API documentation (see apiexample.c).
586
- fixed image polyphase bug (the bottom of some images could be
587
  greenish)

589
  and image sizes non-multiple of 16
590

594

    
595

597
- added MSMPEG4 (aka DivX) compatible encoder. Changed default codec
598
  of AVI and ASF to DIV3.
599
- added -me option to set motion estimation method
600
  (default=log). suppressed redundant -hq option.
601

602
  AVI for example)

611
  multistream support to ffmpeg.
612
- added timeshifting support for live feeds (option ?date=xxx in the
613
  URL)
614
- added high quality image resize code with polyphase filter (need
615
  mmx/see optimization). Enable multiple image size support in ffserver.
616
- added multi live feed support in ffserver
617
- suppressed master feature from ffserver (it should be done with an
618
  external program which opens the .ffm url and writes it to another
619
  ffserver)
620
- added preliminary support for video stream parsing (WAV and AVI half
621
  done). Added proper support for audio/video file conversion in
622
  ffmpeg.

646
  bitrates and large GOP size
647
