485
- fixed phase rounding in img resample filter
486
- add MMX code for polyphase img resample filter
487
- added CPU autodetection
488
- added generic title/author/copyright/comment string handling (ASF and RM
489
  use them)
490
- added SWF demux to extract MP3 track (not usable yet because no MP3
491
  decoder)
492
- added fractional frame rate support
493
- codecs are no longer searched by read_header() (should fix ffserver
494
  segfault)

498
version 0.4.3:
499

    
500
- BGR24 patch (initial patch by Jeroen Vreeken <pe1rxq at amsat.org>)
501
- fixed raw yuv output
502
- added motion rounding support in MPEG-4
503
- fixed motion bug rounding in MSMPEG4
504
- added B-frame handling in video core
505
- added full MPEG-1 decoding support
506
- added partial (frame only) MPEG-2 support
507
- changed the FOURCC code for H.263 to "U263" to be able to see the
508
  +AVI/H.263 file with the UB Video H.263+ decoder. MPlayer works with
509
  this +codec ;) (JuanJo).
510
- Halfpel motion estimation after MB type selection (JuanJo)
511
- added pgm and .Y.U.V output format
512
- suppressed 'img:' protocol. Simply use: /tmp/test%d.[pgm|Y] as input or
513
  output.
514
- added pgmpipe I/O format (original patch from Martin Aumueller
515
  <lists at reserv.at>, but changed completely since we use a format
516
  instead of a protocol)
517

    
518

    
519

    
520
version 0.4.2:
521

    
522
- added H.263/MPEG-4/MSMPEG4 decoding support. MPEG-4 decoding support
523
  (for OpenDivX) is almost complete: 8x8 MVs and rounding are
524
  missing. MSMPEG4 support is complete.
525
- added prototype MPEG-1 decoder. Only I- and P-frames handled yet (it
526
  can decode ffmpeg MPEGs :-)).
527
- added libavcodec API documentation (see apiexample.c).
528
- fixed image polyphase bug (the bottom of some images could be
529
  greenish)
530
- added support for non clipped motion vectors (decoding only)
531
  and image sizes non-multiple of 16
532
- added support for AC prediction (decoding only)
533
- added file overwrite confirmation (can be disabled with -y)
534
- added custom size picture to H.263 using H.263+ (Juanjo)
535

    
536

    
537
version 0.4.1:
538

    
539
- added MSMPEG4 (aka DivX) compatible encoder. Changed default codec
540
  of AVI and ASF to DIV3.
541
- added -me option to set motion estimation method
542
  (default=log). suppressed redundant -hq option.
543
- added options -acodec and -vcodec to force a given codec (useful for
544
  AVI for example)
545
- fixed -an option
546
- improved dct_quantize speed
547
- factorized some motion estimation code
548

    
549

    
550

    
551
version 0.4.0:
552

    
553
- removing grab code from ffserver and moved it to ffmpeg. Added
554
  multistream support to ffmpeg.
555
- added timeshifting support for live feeds (option ?date=xxx in the
556
  URL)
557
- added high quality image resize code with polyphase filter (need
558
  mmx/see optimization). Enable multiple image size support in ffserver.
559
- added multi live feed support in ffserver
560
- suppressed master feature from ffserver (it should be done with an
561
  external program which opens the .ffm url and writes it to another
562
  ffserver)
563
- added preliminary support for video stream parsing (WAV and AVI half
564
  done). Added proper support for audio/video file conversion in
565
  ffmpeg.
566
- added preliminary support for video file sending from ffserver
567
- redesigning I/O subsystem: now using URL based input and output
568
  (see avio.h)
569
- added WAV format support
570
- added "tty user interface" to ffmpeg to stop grabbing gracefully
571
- added MMX/SSE optimizations to SAD (Sums of Absolutes Differences)
572
  (Juan J. Sierralta P. a.k.a. "Juanjo" <juanjo at atmlab.utfsm.cl>)
573
- added MMX DCT from mpeg2_movie 1.5 (Juanjo)
574
- added new motion estimation algorithms, log and phods (Juanjo)
575
- changed directories: libav for format handling, libavcodec for
576
  codecs

- added 'high quality' mode which use motion vectors. It can be used in
589
  real time at low resolution.
590
- fixed rounding problems which caused quality problems at high
591
  bitrates and large GOP size
592
