554

    
555
version 0.4.3:
556

565
  +AVI/H.263 file with the UB Video H.263+ decoder. MPlayer works with
566
  this +codec ;) (JuanJo).
567
- Halfpel motion estimation after MB type selection (JuanJo)
568
- added pgm and .Y.U.V output format

572
  <lists at reserv.at>, but changed completely since we use a format
573
  instead of a protocol)
574

    
575

    
576

577

    
578

579
  (for OpenDivX) is almost complete: 8x8 MVs and rounding are
580
  missing. MSMPEG4 support is complete.
581
- added prototype MPEG-1 decoder. Only I- and P-frames handled yet (it
582
  can decode ffmpeg MPEGs :-)).
583
- added libavcodec API documentation (see apiexample.c).
584
- fixed image polyphase bug (the bottom of some images could be
585
  greenish)

587
  and image sizes non-multiple of 16
588

591

    
592

    
593
version 0.4.1:
594

    
595
- added MSMPEG4 (aka DivX) compatible encoder. Changed default codec
596
  of AVI and ASF to DIV3.
597
- added -me option to set motion estimation method
598
  (default=log). suppressed redundant -hq option.
599

600
  AVI for example)
601

609
  multistream support to ffmpeg.
610
- added timeshifting support for live feeds (option ?date=xxx in the
611
  URL)
612
- added high quality image resize code with polyphase filter (need
613
  mmx/see optimization). Enable multiple image size support in ffserver.
614
- added multi live feed support in ffserver
615
- suppressed master feature from ffserver (it should be done with an
616
  external program which opens the .ffm url and writes it to another
617
  ffserver)
618
- added preliminary support for video stream parsing (WAV and AVI half
619
  done). Added proper support for audio/video file conversion in
620
  ffmpeg.
621
- added preliminary support for video file sending from ffserver
622

644
  bitrates and large GOP size
645
