484
  <bjorn.e.lindgren at telia.com>).
485
- added MPEG demuxer (MPEG-1 and 2 compatible).
486
- added ASF demuxer
487
- added prototype RM demuxer
488
- added AC3 decoding (done with libac3 by Aaron Holtzman)
489
- added decoding codec parameter guessing (.e.g. for MPEG, because the
490
  header does not include them)
491
- fixed header generation in MPEG-1, AVI and ASF muxer: wmplayer can now
492
  play them (only tested video)
493
- fixed H.263 white bug
494
- fixed phase rounding in img resample filter
495
- add MMX code for polyphase img resample filter
496
- added CPU autodetection
497
- added generic title/author/copyright/comment string handling (ASF and RM
498
  use them)
499
- added SWF demux to extract MP3 track (not usable yet because no MP3
500
  decoder)
501
- added fractional frame rate support
502
- codecs are no longer searched by read_header() (should fix ffserver
503
  segfault)
504

    
505

    
506
version 0.4.3:
507

    
508
- BGR24 patch (initial patch by Jeroen Vreeken <pe1rxq at amsat.org>)
509
- fixed raw yuv output
510
- added motion rounding support in MPEG-4
511
- fixed motion bug rounding in MSMPEG4
512
- added B-frame handling in video core
513
- added full MPEG-1 decoding support
514
- added partial (frame only) MPEG-2 support
515
- changed the FOURCC code for H.263 to "U263" to be able to see the
516
  +AVI/H.263 file with the UB Video H.263+ decoder. MPlayer works with
517
  this +codec ;) (JuanJo).
518
- Halfpel motion estimation after MB type selection (JuanJo)
519
- added pgm and .Y.U.V output format
520
- suppressed 'img:' protocol. Simply use: /tmp/test%d.[pgm|Y] as input or
521
  output.
522
- added pgmpipe I/O format (original patch from Martin Aumueller
523
  <lists at reserv.at>, but changed completely since we use a format
524
  instead of a protocol)
525

    
526

    
527
version 0.4.2:
528

    
529
- added H.263/MPEG-4/MSMPEG4 decoding support. MPEG-4 decoding support
530
  (for OpenDivX) is almost complete: 8x8 MVs and rounding are
531
  missing. MSMPEG4 support is complete.
532
- added prototype MPEG-1 decoder. Only I- and P-frames handled yet (it
533
  can decode ffmpeg MPEGs :-)).
534
- added libavcodec API documentation (see apiexample.c).
535
- fixed image polyphase bug (the bottom of some images could be
536
  greenish)
537
- added support for non clipped motion vectors (decoding only)
538
  and image sizes non-multiple of 16
539
- added support for AC prediction (decoding only)
540
- added file overwrite confirmation (can be disabled with -y)
541
- added custom size picture to H.263 using H.263+ (Juanjo)
542

    
543

    
544
version 0.4.1:
545

    
546
- added MSMPEG4 (aka DivX) compatible encoder. Changed default codec
547
  of AVI and ASF to DIV3.
548
- added -me option to set motion estimation method
549
  (default=log). suppressed redundant -hq option.
550
- added options -acodec and -vcodec to force a given codec (useful for
551
  AVI for example)
552
- fixed -an option
553
- improved dct_quantize speed
554
- factorized some motion estimation code
555

    
556

    
557
version 0.4.0:
558

    
559
- removing grab code from ffserver and moved it to ffmpeg. Added
560
  multistream support to ffmpeg.
561
- added timeshifting support for live feeds (option ?date=xxx in the
562
  URL)
563
- added high quality image resize code with polyphase filter (need
564
  mmx/see optimization). Enable multiple image size support in ffserver.
565
- added multi live feed support in ffserver
566
- suppressed master feature from ffserver (it should be done with an
567
  external program which opens the .ffm url and writes it to another
568
  ffserver)
569
- added preliminary support for video stream parsing (WAV and AVI half
570
  done). Added proper support for audio/video file conversion in
571
  ffmpeg.
572
- added preliminary support for video file sending from ffserver
573
- redesigning I/O subsystem: now using URL based input and output
574
  (see avio.h)
575
- added WAV format support
576
- added "tty user interface" to ffmpeg to stop grabbing gracefully
577
- added MMX/SSE optimizations to SAD (Sums of Absolutes Differences)
578
  (Juan J. Sierralta P. a.k.a. "Juanjo" <juanjo at atmlab.utfsm.cl>)
579
- added MMX DCT from mpeg2_movie 1.5 (Juanjo)
580
- added new motion estimation algorithms, log and phods (Juanjo)
581
- changed directories: libav for format handling, libavcodec for
582
  codecs

593
  real time at low resolution.
594
- fixed rounding problems which caused quality problems at high
595
  bitrates and large GOP size
596

    
597
