531
- added prototype RM demuxer
532

545
- added fractional frame rate support
546

549

    
550
version 0.4.3:
551

559
- changed the FOURCC code for H.263 to "U263" to be able to see the
560
  +AVI/H.263 file with the UB Video H.263+ decoder. MPlayer works with
561
  this +codec ;) (JuanJo).
562
- Halfpel motion estimation after MB type selection (JuanJo)
563
- added pgm and .Y.U.V output format
564

567
  <lists at reserv.at>, but changed completely since we use a format
568
  instead of a protocol)
569

    
570

    
571
version 0.4.2:
572

    
573

574
  (for OpenDivX) is almost complete: 8x8 MVs and rounding are
575
  missing. MSMPEG4 support is complete.
576
- added prototype MPEG-1 decoder. Only I- and P-frames handled yet (it
577
  can decode ffmpeg MPEGs :-)).
578
- added libavcodec API documentation (see apiexample.c).
579
- fixed image polyphase bug (the bottom of some images could be
580
  greenish)
581

582
  and image sizes non-multiple of 16
583

586

    
587

    
588
version 0.4.1:
589

    
590
- added MSMPEG4 (aka DivX) compatible encoder. Changed default codec
591
  of AVI and ASF to DIV3.
592
- added -me option to set motion estimation method
593
  (default=log). suppressed redundant -hq option.
594
- added options -acodec and -vcodec to force a given codec (useful for
595
  AVI for example)
596
- fixed -an option
597

598
- factorized some motion estimation code
599

    
600

604
  multistream support to ffmpeg.
605
- added timeshifting support for live feeds (option ?date=xxx in the
606
  URL)
607
- added high quality image resize code with polyphase filter (need
608
  mmx/see optimization). Enable multiple image size support in ffserver.
609
- added multi live feed support in ffserver
610
- suppressed master feature from ffserver (it should be done with an
611
  external program which opens the .ffm url and writes it to another
612
  ffserver)
613
- added preliminary support for video stream parsing (WAV and AVI half
614
  done). Added proper support for audio/video file conversion in
615
  ffmpeg.
616
- added preliminary support for video file sending from ffserver
617
- redesigning I/O subsystem: now using URL based input and output

- fixed rounding problems which caused quality problems at high
639
  bitrates and large GOP size
640
