530
- added decoding codec parameter guessing (.e.g. for MPEG, because the

542
- added fractional frame rate support
543

544
  segfault)

546

    
547
version 0.4.3:
548

556
- changed the FOURCC code for H.263 to "U263" to be able to see the
557
  +AVI/H.263 file with the UB Video H.263+ decoder. MPlayer works with
558
  this +codec ;) (JuanJo).
559
- Halfpel motion estimation after MB type selection (JuanJo)
560
- added pgm and .Y.U.V output format
561

562
  output.
563
- added pgmpipe I/O format (original patch from Martin Aumueller
564
  <lists at reserv.at>, but changed completely since we use a format
565
  instead of a protocol)
566

    
567

    
568
version 0.4.2:
569

    
570
- added H.263/MPEG-4/MSMPEG4 decoding support. MPEG-4 decoding support
571
  (for OpenDivX) is almost complete: 8x8 MVs and rounding are
572
  missing. MSMPEG4 support is complete.
573
- added prototype MPEG-1 decoder. Only I- and P-frames handled yet (it
574
  can decode ffmpeg MPEGs :-)).
575
- added libavcodec API documentation (see apiexample.c).
576
- fixed image polyphase bug (the bottom of some images could be
577
  greenish)
578

579
  and image sizes non-multiple of 16
580

581
- added file overwrite confirmation (can be disabled with -y)
582

583

    
584

    
585
version 0.4.1:
586

    
587
- added MSMPEG4 (aka DivX) compatible encoder. Changed default codec
588
  of AVI and ASF to DIV3.
589
- added -me option to set motion estimation method
590
  (default=log). suppressed redundant -hq option.
591
- added options -acodec and -vcodec to force a given codec (useful for
592
  AVI for example)
593
- fixed -an option
594
- improved dct_quantize speed
595
- factorized some motion estimation code
596

    
597

601
  multistream support to ffmpeg.
602
- added timeshifting support for live feeds (option ?date=xxx in the
603
  URL)
604
- added high quality image resize code with polyphase filter (need
605
  mmx/see optimization). Enable multiple image size support in ffserver.
606
- added multi live feed support in ffserver
607
- suppressed master feature from ffserver (it should be done with an
608
  external program which opens the .ffm url and writes it to another
609
  ffserver)
610
- added preliminary support for video stream parsing (WAV and AVI half
611
  done). Added proper support for audio/video file conversion in
612
  ffmpeg.
613
- added preliminary support for video file sending from ffserver
614
- redesigning I/O subsystem: now using URL based input and output

- fixed rounding problems which caused quality problems at high
636
  bitrates and large GOP size
637
