517
- added prototype RM demuxer
518

519
- added decoding codec parameter guessing (.e.g. for MPEG, because the
520

522
  play them (only tested video)
523

525
- add MMX code for polyphase img resample filter

530
  decoder)
531
- added fractional frame rate support
532

533
  segfault)

535

    
536
version 0.4.3:
537

544
- added partial (frame only) MPEG-2 support
545
- changed the FOURCC code for H.263 to "U263" to be able to see the
546
  +AVI/H.263 file with the UB Video H.263+ decoder. MPlayer works with
547
  this +codec ;) (JuanJo).
548
- Halfpel motion estimation after MB type selection (JuanJo)
549
- added pgm and .Y.U.V output format
550
- suppressed 'img:' protocol. Simply use: /tmp/test%d.[pgm|Y] as input or
551
  output.
552
- added pgmpipe I/O format (original patch from Martin Aumueller
553
  <lists at reserv.at>, but changed completely since we use a format
554
  instead of a protocol)
555

    
556

    
557
version 0.4.2:
558

    
559
- added H.263/MPEG-4/MSMPEG4 decoding support. MPEG-4 decoding support
560
  (for OpenDivX) is almost complete: 8x8 MVs and rounding are
561
  missing. MSMPEG4 support is complete.
562
- added prototype MPEG-1 decoder. Only I- and P-frames handled yet (it
563
  can decode ffmpeg MPEGs :-)).
564
- added libavcodec API documentation (see apiexample.c).
565
- fixed image polyphase bug (the bottom of some images could be
566
  greenish)
567

568
  and image sizes non-multiple of 16
569

570
- added file overwrite confirmation (can be disabled with -y)
571
- added custom size picture to H.263 using H.263+ (Juanjo)
572

    
573

    
574
version 0.4.1:
575

    
576
- added MSMPEG4 (aka DivX) compatible encoder. Changed default codec
577
  of AVI and ASF to DIV3.
578
- added -me option to set motion estimation method
579
  (default=log). suppressed redundant -hq option.
580
- added options -acodec and -vcodec to force a given codec (useful for
581
  AVI for example)
582
- fixed -an option
583
- improved dct_quantize speed
584
- factorized some motion estimation code
585

    
586

590
  multistream support to ffmpeg.
591
- added timeshifting support for live feeds (option ?date=xxx in the
592
  URL)
593
- added high quality image resize code with polyphase filter (need
594
  mmx/see optimization). Enable multiple image size support in ffserver.
595
- added multi live feed support in ffserver
596
- suppressed master feature from ffserver (it should be done with an
597
  external program which opens the .ffm url and writes it to another
598
  ffserver)
599
- added preliminary support for video stream parsing (WAV and AVI half
600
  done). Added proper support for audio/video file conversion in
601
  ffmpeg.
602
- added preliminary support for video file sending from ffserver
603
- redesigning I/O subsystem: now using URL based input and output

625
  bitrates and large GOP size
626
