529
- added prototype RM demuxer
530

531

543
- added fractional frame rate support
544

547

    
548
version 0.4.3:
549

557
- changed the FOURCC code for H.263 to "U263" to be able to see the
558
  +AVI/H.263 file with the UB Video H.263+ decoder. MPlayer works with
559
  this +codec ;) (JuanJo).
560
- Halfpel motion estimation after MB type selection (JuanJo)
561
- added pgm and .Y.U.V output format
562

565
  <lists at reserv.at>, but changed completely since we use a format
566
  instead of a protocol)
567

    
568

    
569
version 0.4.2:
570

    
571
- added H.263/MPEG-4/MSMPEG4 decoding support. MPEG-4 decoding support
572
  (for OpenDivX) is almost complete: 8x8 MVs and rounding are
573
  missing. MSMPEG4 support is complete.
574
- added prototype MPEG-1 decoder. Only I- and P-frames handled yet (it
575
  can decode ffmpeg MPEGs :-)).
576
- added libavcodec API documentation (see apiexample.c).
577
- fixed image polyphase bug (the bottom of some images could be
578
  greenish)
579

580
  and image sizes non-multiple of 16
581

582
- added file overwrite confirmation (can be disabled with -y)
583

584

    
585

    
586
version 0.4.1:
587

    
588
- added MSMPEG4 (aka DivX) compatible encoder. Changed default codec
589
  of AVI and ASF to DIV3.
590
- added -me option to set motion estimation method
591
  (default=log). suppressed redundant -hq option.
592
- added options -acodec and -vcodec to force a given codec (useful for
593
  AVI for example)
594
- fixed -an option
595
- improved dct_quantize speed
596
- factorized some motion estimation code
597

    
598

    
599

602
  multistream support to ffmpeg.
603
- added timeshifting support for live feeds (option ?date=xxx in the
604
  URL)
605
- added high quality image resize code with polyphase filter (need
606
  mmx/see optimization). Enable multiple image size support in ffserver.
607
- added multi live feed support in ffserver
608
- suppressed master feature from ffserver (it should be done with an
609
  external program which opens the .ffm url and writes it to another
610
  ffserver)
611
- added preliminary support for video stream parsing (WAV and AVI half
612
  done). Added proper support for audio/video file conversion in
613
  ffmpeg.
614
- added preliminary support for video file sending from ffserver
615
- redesigning I/O subsystem: now using URL based input and output

- fixed rounding problems which caused quality problems at high
637
  bitrates and large GOP size
638
