  play them (only tested video)
520

532

    
533
version 0.4.3:
534

542
- changed the FOURCC code for H.263 to "U263" to be able to see the
543
  +AVI/H.263 file with the UB Video H.263+ decoder. MPlayer works with
544
  this +codec ;) (JuanJo).
545
- Halfpel motion estimation after MB type selection (JuanJo)
546
- added pgm and .Y.U.V output format
547

548
  output.
549
- added pgmpipe I/O format (original patch from Martin Aumueller
550
  <lists at reserv.at>, but changed completely since we use a format
551
  instead of a protocol)
552

    
553

    
554
version 0.4.2:
555

    
556
- added H.263/MPEG-4/MSMPEG4 decoding support. MPEG-4 decoding support
557
  (for OpenDivX) is almost complete: 8x8 MVs and rounding are
558
  missing. MSMPEG4 support is complete.
559
- added prototype MPEG-1 decoder. Only I- and P-frames handled yet (it
560
  can decode ffmpeg MPEGs :-)).
561
- added libavcodec API documentation (see apiexample.c).
562
- fixed image polyphase bug (the bottom of some images could be
563
  greenish)
564

565
  and image sizes non-multiple of 16
566

567
- added file overwrite confirmation (can be disabled with -y)
568
- added custom size picture to H.263 using H.263+ (Juanjo)
569

    
570

    
571
version 0.4.1:
572

    
573
- added MSMPEG4 (aka DivX) compatible encoder. Changed default codec
574
  of AVI and ASF to DIV3.
575
- added -me option to set motion estimation method
576
  (default=log). suppressed redundant -hq option.
577
- added options -acodec and -vcodec to force a given codec (useful for
578
  AVI for example)
579
- fixed -an option
580
- improved dct_quantize speed
581
- factorized some motion estimation code
582

587
  multistream support to ffmpeg.
588
- added timeshifting support for live feeds (option ?date=xxx in the
589
  URL)
590
- added high quality image resize code with polyphase filter (need
591
  mmx/see optimization). Enable multiple image size support in ffserver.
592
- added multi live feed support in ffserver
593
- suppressed master feature from ffserver (it should be done with an
594
  external program which opens the .ffm url and writes it to another
595
  ffserver)
596
- added preliminary support for video stream parsing (WAV and AVI half
597
  done). Added proper support for audio/video file conversion in
598
  ffmpeg.
599
- added preliminary support for video file sending from ffserver
600
