530
- added prototype RM demuxer
531

532
- added decoding codec parameter guessing (.e.g. for MPEG, because the

544
- added fractional frame rate support
545

548

    
549
version 0.4.3:
550

558
- changed the FOURCC code for H.263 to "U263" to be able to see the
559
  +AVI/H.263 file with the UB Video H.263+ decoder. MPlayer works with
560
  this +codec ;) (JuanJo).
561
- Halfpel motion estimation after MB type selection (JuanJo)
562
- added pgm and .Y.U.V output format
563

566
  <lists at reserv.at>, but changed completely since we use a format
567
  instead of a protocol)
568

    
569

    
570
version 0.4.2:
571

    
572
- added H.263/MPEG-4/MSMPEG4 decoding support. MPEG-4 decoding support
573
  (for OpenDivX) is almost complete: 8x8 MVs and rounding are
574
  missing. MSMPEG4 support is complete.
575
- added prototype MPEG-1 decoder. Only I- and P-frames handled yet (it
576
  can decode ffmpeg MPEGs :-)).
577
- added libavcodec API documentation (see apiexample.c).
578
- fixed image polyphase bug (the bottom of some images could be
579
  greenish)
580

581
  and image sizes non-multiple of 16
582

583
- added file overwrite confirmation (can be disabled with -y)
584

585

    
586

    
587
version 0.4.1:
588

    
589
- added MSMPEG4 (aka DivX) compatible encoder. Changed default codec
590
  of AVI and ASF to DIV3.
591
- added -me option to set motion estimation method
592
  (default=log). suppressed redundant -hq option.
593
- added options -acodec and -vcodec to force a given codec (useful for
594
  AVI for example)
595
- fixed -an option
596
- improved dct_quantize speed
597
- factorized some motion estimation code
598

    
599

    
600

603
  multistream support to ffmpeg.
604
- added timeshifting support for live feeds (option ?date=xxx in the
605
  URL)
606
- added high quality image resize code with polyphase filter (need
607
  mmx/see optimization). Enable multiple image size support in ffserver.
608
- added multi live feed support in ffserver
609
- suppressed master feature from ffserver (it should be done with an
610
  external program which opens the .ffm url and writes it to another
611
  ffserver)
612
- added preliminary support for video stream parsing (WAV and AVI half
613
  done). Added proper support for audio/video file conversion in
614
  ffmpeg.
615
- added preliminary support for video file sending from ffserver
616
- redesigning I/O subsystem: now using URL based input and output

- fixed rounding problems which caused quality problems at high
638
  bitrates and large GOP size
639
