545

    
546
version 0.4.3:
547

555
- changed the FOURCC code for H.263 to "U263" to be able to see the
556
  +AVI/H.263 file with the UB Video H.263+ decoder. MPlayer works with
557
  this +codec ;) (JuanJo).
558
- Halfpel motion estimation after MB type selection (JuanJo)
559
- added pgm and .Y.U.V output format
560

561
  output.
562
- added pgmpipe I/O format (original patch from Martin Aumueller
563
  <lists at reserv.at>, but changed completely since we use a format
564
  instead of a protocol)
565

    
566

    
567
version 0.4.2:
568

    
569
- added H.263/MPEG-4/MSMPEG4 decoding support. MPEG-4 decoding support
570
  (for OpenDivX) is almost complete: 8x8 MVs and rounding are
571
  missing. MSMPEG4 support is complete.
572
- added prototype MPEG-1 decoder. Only I- and P-frames handled yet (it
573
  can decode ffmpeg MPEGs :-)).
574
- added libavcodec API documentation (see apiexample.c).
575
- fixed image polyphase bug (the bottom of some images could be
576
  greenish)
577

578
  and image sizes non-multiple of 16
579

580
- added file overwrite confirmation (can be disabled with -y)
581

582

    
583

    
584
version 0.4.1:
585

    
586
- added MSMPEG4 (aka DivX) compatible encoder. Changed default codec
587
  of AVI and ASF to DIV3.
588
- added -me option to set motion estimation method
589
  (default=log). suppressed redundant -hq option.
590
- added options -acodec and -vcodec to force a given codec (useful for
591
  AVI for example)
592
- fixed -an option
593
- improved dct_quantize speed
594
- factorized some motion estimation code
595

    
596

600
  multistream support to ffmpeg.
601
- added timeshifting support for live feeds (option ?date=xxx in the
602
  URL)
603
- added high quality image resize code with polyphase filter (need
604
  mmx/see optimization). Enable multiple image size support in ffserver.
605
- added multi live feed support in ffserver
606
- suppressed master feature from ffserver (it should be done with an
607
  external program which opens the .ffm url and writes it to another
608
  ffserver)
609
- added preliminary support for video stream parsing (WAV and AVI half
610
  done). Added proper support for audio/video file conversion in
611
  ffmpeg.
612
- added preliminary support for video file sending from ffserver
613
- redesigning I/O subsystem: now using URL based input and output

- fixed rounding problems which caused quality problems at high
635
  bitrates and large GOP size
636
