551

    
552
version 0.4.3:
553

562
  +AVI/H.263 file with the UB Video H.263+ decoder. MPlayer works with
563
  this +codec ;) (JuanJo).
564
- Halfpel motion estimation after MB type selection (JuanJo)
565
- added pgm and .Y.U.V output format
566

569
  <lists at reserv.at>, but changed completely since we use a format
570
  instead of a protocol)
571

    
572

    
573
version 0.4.2:
574

    
575

576
  (for OpenDivX) is almost complete: 8x8 MVs and rounding are
577
  missing. MSMPEG4 support is complete.
578
- added prototype MPEG-1 decoder. Only I- and P-frames handled yet (it
579
  can decode ffmpeg MPEGs :-)).
580
- added libavcodec API documentation (see apiexample.c).
581
- fixed image polyphase bug (the bottom of some images could be
582
  greenish)
583

584
  and image sizes non-multiple of 16
585

588

    
589

    
590
version 0.4.1:
591

    
592
- added MSMPEG4 (aka DivX) compatible encoder. Changed default codec
593
  of AVI and ASF to DIV3.
594
- added -me option to set motion estimation method
595
  (default=log). suppressed redundant -hq option.
596
- added options -acodec and -vcodec to force a given codec (useful for
597
  AVI for example)
598
- fixed -an option
599

606
  multistream support to ffmpeg.
607
- added timeshifting support for live feeds (option ?date=xxx in the
608
  URL)
609
- added high quality image resize code with polyphase filter (need
610
  mmx/see optimization). Enable multiple image size support in ffserver.
611
- added multi live feed support in ffserver
612
- suppressed master feature from ffserver (it should be done with an
613
  external program which opens the .ffm url and writes it to another
614
  ffserver)
615
- added preliminary support for video stream parsing (WAV and AVI half
616
  done). Added proper support for audio/video file conversion in
617
  ffmpeg.
618
- added preliminary support for video file sending from ffserver
619
- redesigning I/O subsystem: now using URL based input and output

641
  bitrates and large GOP size
642
