550

    
551
version 0.4.3:
552

561
  +AVI/H.263 file with the UB Video H.263+ decoder. MPlayer works with
562
  this +codec ;) (JuanJo).
563
- Halfpel motion estimation after MB type selection (JuanJo)
564
- added pgm and .Y.U.V output format

568
  <lists at reserv.at>, but changed completely since we use a format
569
  instead of a protocol)
570

    
571

    
572
version 0.4.2:
573

    
574

575
  (for OpenDivX) is almost complete: 8x8 MVs and rounding are
576
  missing. MSMPEG4 support is complete.
577
- added prototype MPEG-1 decoder. Only I- and P-frames handled yet (it
578
  can decode ffmpeg MPEGs :-)).
579
- added libavcodec API documentation (see apiexample.c).
580
- fixed image polyphase bug (the bottom of some images could be
581
  greenish)
582

583
  and image sizes non-multiple of 16
584

587

    
588

    
589
version 0.4.1:
590

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

605
  multistream support to ffmpeg.
606
- added timeshifting support for live feeds (option ?date=xxx in the
607
  URL)
608
- added high quality image resize code with polyphase filter (need
609
  mmx/see optimization). Enable multiple image size support in ffserver.
610
- added multi live feed support in ffserver
611
- suppressed master feature from ffserver (it should be done with an
612
  external program which opens the .ffm url and writes it to another
613
  ffserver)
614
- added preliminary support for video stream parsing (WAV and AVI half
615
  done). Added proper support for audio/video file conversion in
616
  ffmpeg.
617
- added preliminary support for video file sending from ffserver
618
- redesigning I/O subsystem: now using URL based input and output

640
  bitrates and large GOP size
641
