553

    
554
version 0.4.3:
555

564
  +AVI/H.263 file with the UB Video H.263+ decoder. MPlayer works with
565
  this +codec ;) (JuanJo).
566
- Halfpel motion estimation after MB type selection (JuanJo)
567
- added pgm and .Y.U.V output format

571
  <lists at reserv.at>, but changed completely since we use a format
572
  instead of a protocol)
573

    
574

    
575
version 0.4.2:
576

    
577

578
  (for OpenDivX) is almost complete: 8x8 MVs and rounding are
579
  missing. MSMPEG4 support is complete.
580
- added prototype MPEG-1 decoder. Only I- and P-frames handled yet (it
581
  can decode ffmpeg MPEGs :-)).
582
- added libavcodec API documentation (see apiexample.c).
583
- fixed image polyphase bug (the bottom of some images could be
584
  greenish)

586
  and image sizes non-multiple of 16
587

590

    
591

    
592
version 0.4.1:
593

    
594
- added MSMPEG4 (aka DivX) compatible encoder. Changed default codec
595
  of AVI and ASF to DIV3.
596
- added -me option to set motion estimation method
597
  (default=log). suppressed redundant -hq option.
598
- added options -acodec and -vcodec to force a given codec (useful for
599
  AVI for example)
600

608
  multistream support to ffmpeg.
609
- added timeshifting support for live feeds (option ?date=xxx in the
610
  URL)
611
- added high quality image resize code with polyphase filter (need
612
  mmx/see optimization). Enable multiple image size support in ffserver.
613
- added multi live feed support in ffserver
614
- suppressed master feature from ffserver (it should be done with an
615
  external program which opens the .ffm url and writes it to another
616
  ffserver)
617
- added preliminary support for video stream parsing (WAV and AVI half
618
  done). Added proper support for audio/video file conversion in
619
  ffmpeg.
620
- added preliminary support for video file sending from ffserver
621
- redesigning I/O subsystem: now using URL based input and output

643
  bitrates and large GOP size
644
