524
- added prototype RM demuxer
525

526
- added decoding codec parameter guessing (.e.g. for MPEG, because the
527
  header does not include them)
528

537
  decoder)
538
- added fractional frame rate support
539
- codecs are no longer searched by read_header() (should fix ffserver
540
  segfault)
541

    
542

    
543
version 0.4.3:
544

    
545

551
- added partial (frame only) MPEG-2 support
552
- changed the FOURCC code for H.263 to "U263" to be able to see the
553
  +AVI/H.263 file with the UB Video H.263+ decoder. MPlayer works with
554
  this +codec ;) (JuanJo).
555
- Halfpel motion estimation after MB type selection (JuanJo)
556
- added pgm and .Y.U.V output format
557
- suppressed 'img:' protocol. Simply use: /tmp/test%d.[pgm|Y] as input or
558
  output.
559
- added pgmpipe I/O format (original patch from Martin Aumueller
560
  <lists at reserv.at>, but changed completely since we use a format
561
  instead of a protocol)
562

    
563

    
564
version 0.4.2:
565

    
566
- added H.263/MPEG-4/MSMPEG4 decoding support. MPEG-4 decoding support
567
  (for OpenDivX) is almost complete: 8x8 MVs and rounding are
568
  missing. MSMPEG4 support is complete.
569
- added prototype MPEG-1 decoder. Only I- and P-frames handled yet (it
570
  can decode ffmpeg MPEGs :-)).
571
- added libavcodec API documentation (see apiexample.c).
572
- fixed image polyphase bug (the bottom of some images could be
573
  greenish)
574
- added support for non clipped motion vectors (decoding only)
575
  and image sizes non-multiple of 16
576
- added support for AC prediction (decoding only)
577
- added file overwrite confirmation (can be disabled with -y)
578
- added custom size picture to H.263 using H.263+ (Juanjo)
579

    
580

    
581
version 0.4.1:
582

    
583
- added MSMPEG4 (aka DivX) compatible encoder. Changed default codec
584
  of AVI and ASF to DIV3.
585
- added -me option to set motion estimation method
586
  (default=log). suppressed redundant -hq option.
587
- added options -acodec and -vcodec to force a given codec (useful for
588
  AVI for example)
589
- fixed -an option
590
- improved dct_quantize speed
591
- factorized some motion estimation code
592

    
593

    
594
version 0.4.0:
595

    
596
- removing grab code from ffserver and moved it to ffmpeg. Added
597
  multistream support to ffmpeg.
598
- added timeshifting support for live feeds (option ?date=xxx in the
599
  URL)
600
- added high quality image resize code with polyphase filter (need
601
  mmx/see optimization). Enable multiple image size support in ffserver.
602
- added multi live feed support in ffserver
603
- suppressed master feature from ffserver (it should be done with an
604
  external program which opens the .ffm url and writes it to another
605
  ffserver)
606
- added preliminary support for video stream parsing (WAV and AVI half
607
  done). Added proper support for audio/video file conversion in
608
  ffmpeg.
609
- added preliminary support for video file sending from ffserver
610
- redesigning I/O subsystem: now using URL based input and output
611
  (see avio.h)
612
- added WAV format support
613
- added "tty user interface" to ffmpeg to stop grabbing gracefully
614

616
- added MMX DCT from mpeg2_movie 1.5 (Juanjo)
617

- fixed rounding problems which caused quality problems at high
632
  bitrates and large GOP size
633
