555

    
556
version 0.4.3:
557

566
  +AVI/H.263 file with the UB Video H.263+ decoder. MPlayer works with

  this +codec ;) (JuanJo).
568
- Halfpel motion estimation after MB type selection (JuanJo)
569
- added pgm and .Y.U.V output format

573
  <lists at reserv.at>, but changed completely since we use a format
574
  instead of a protocol)
575

    
576

    
577

578

    
579

580
  (for OpenDivX) is almost complete: 8x8 MVs and rounding are
581
  missing. MSMPEG4 support is complete.
582
- added prototype MPEG-1 decoder. Only I- and P-frames handled yet (it
583
  can decode ffmpeg MPEGs :-)).
584
- added libavcodec API documentation (see apiexample.c).
585
- fixed image polyphase bug (the bottom of some images could be
586
  greenish)

588
  and image sizes non-multiple of 16
589

593

    
594
version 0.4.1:
595

    
596
- added MSMPEG4 (aka DivX) compatible encoder. Changed default codec
597
  of AVI and ASF to DIV3.
598
- added -me option to set motion estimation method
599
  (default=log). suppressed redundant -hq option.
600

601
  AVI for example)
602

610
  multistream support to ffmpeg.
611
- added timeshifting support for live feeds (option ?date=xxx in the
612
  URL)
613
- added high quality image resize code with polyphase filter (need
614
  mmx/see optimization). Enable multiple image size support in ffserver.
615
- added multi live feed support in ffserver
616
- suppressed master feature from ffserver (it should be done with an
617
  external program which opens the .ffm url and writes it to another
618
  ffserver)
619
- added preliminary support for video stream parsing (WAV and AVI half
620
  done). Added proper support for audio/video file conversion in
621
  ffmpeg.
622

645
  bitrates and large GOP size
646
