544

    
545
version 0.4.3:
546

554
- changed the FOURCC code for H.263 to "U263" to be able to see the
555
  +AVI/H.263 file with the UB Video H.263+ decoder. MPlayer works with
556
  this +codec ;) (JuanJo).
557
- Halfpel motion estimation after MB type selection (JuanJo)
558
- added pgm and .Y.U.V output format
559

560
  output.
561
- added pgmpipe I/O format (original patch from Martin Aumueller
562
  <lists at reserv.at>, but changed completely since we use a format
563
  instead of a protocol)
564

    
565

    
566
version 0.4.2:
567

    
568
- added H.263/MPEG-4/MSMPEG4 decoding support. MPEG-4 decoding support
569
  (for OpenDivX) is almost complete: 8x8 MVs and rounding are
570
  missing. MSMPEG4 support is complete.
571
- added prototype MPEG-1 decoder. Only I- and P-frames handled yet (it
572
  can decode ffmpeg MPEGs :-)).
573
- added libavcodec API documentation (see apiexample.c).
574
- fixed image polyphase bug (the bottom of some images could be
575
  greenish)
576

577
  and image sizes non-multiple of 16
578

579
- added file overwrite confirmation (can be disabled with -y)
580

581

    
582

    
583
version 0.4.1:
584

    
585
- added MSMPEG4 (aka DivX) compatible encoder. Changed default codec
586
  of AVI and ASF to DIV3.
587
- added -me option to set motion estimation method
588
  (default=log). suppressed redundant -hq option.
589
- added options -acodec and -vcodec to force a given codec (useful for
590
  AVI for example)
591
- fixed -an option
592
- improved dct_quantize speed
593
- factorized some motion estimation code
594

    
595

599
  multistream support to ffmpeg.
600
- added timeshifting support for live feeds (option ?date=xxx in the
601
  URL)
602
- added high quality image resize code with polyphase filter (need
603
  mmx/see optimization). Enable multiple image size support in ffserver.
604
- added multi live feed support in ffserver
605
- suppressed master feature from ffserver (it should be done with an
606
  external program which opens the .ffm url and writes it to another
607
  ffserver)
608
- added preliminary support for video stream parsing (WAV and AVI half
609
  done). Added proper support for audio/video file conversion in
610
  ffmpeg.
611
- added preliminary support for video file sending from ffserver
612
- redesigning I/O subsystem: now using URL based input and output

- fixed rounding problems which caused quality problems at high
634
  bitrates and large GOP size
635
