484
version 0.4.4:
485

    
486
- fixed some std header definitions (Bjorn Lindgren
487
  <bjorn.e.lindgren at telia.com>).
488
- added MPEG demuxer (MPEG-1 and 2 compatible).
489
- added ASF demuxer
490
- added prototype RM demuxer
491
- added AC3 decoding (done with libac3 by Aaron Holtzman)
492
- added decoding codec parameter guessing (.e.g. for MPEG, because the
493
  header does not include them)
494
- fixed header generation in MPEG-1, AVI and ASF muxer: wmplayer can now
495
  play them (only tested video)
496
- fixed H.263 white bug
497
- fixed phase rounding in img resample filter
498
- add MMX code for polyphase img resample filter
499
- added CPU autodetection
500
- added generic title/author/copyright/comment string handling (ASF and RM
501
  use them)
502
- added SWF demux to extract MP3 track (not usable yet because no MP3
503
  decoder)
504
- added fractional frame rate support
505
- codecs are no longer searched by read_header() (should fix ffserver
506
  segfault)
507

    
508

    
509
version 0.4.3:
510

    
511
- BGR24 patch (initial patch by Jeroen Vreeken <pe1rxq at amsat.org>)
512
- fixed raw yuv output
513
- added motion rounding support in MPEG-4
514
- fixed motion bug rounding in MSMPEG4
515
- added B-frame handling in video core
516
- added full MPEG-1 decoding support
517
- added partial (frame only) MPEG-2 support
518
- changed the FOURCC code for H.263 to "U263" to be able to see the
519
  +AVI/H.263 file with the UB Video H.263+ decoder. MPlayer works with
520
  this +codec ;) (JuanJo).
521
- Halfpel motion estimation after MB type selection (JuanJo)
522
- added pgm and .Y.U.V output format
523
- suppressed 'img:' protocol. Simply use: /tmp/test%d.[pgm|Y] as input or
524
  output.
525
- added pgmpipe I/O format (original patch from Martin Aumueller
526
  <lists at reserv.at>, but changed completely since we use a format
527
  instead of a protocol)
528

    
529

    
530
version 0.4.2:
531

    
532
- added H.263/MPEG-4/MSMPEG4 decoding support. MPEG-4 decoding support
533
  (for OpenDivX) is almost complete: 8x8 MVs and rounding are
534
  missing. MSMPEG4 support is complete.
535
- added prototype MPEG-1 decoder. Only I- and P-frames handled yet (it
536
  can decode ffmpeg MPEGs :-)).
537
- added libavcodec API documentation (see apiexample.c).
538
- fixed image polyphase bug (the bottom of some images could be
539
  greenish)
540
- added support for non clipped motion vectors (decoding only)
541
  and image sizes non-multiple of 16
542
- added support for AC prediction (decoding only)
543
- added file overwrite confirmation (can be disabled with -y)
544
- added custom size picture to H.263 using H.263+ (Juanjo)
545

    
546

    
547
version 0.4.1:
548

    
549
- added MSMPEG4 (aka DivX) compatible encoder. Changed default codec
550
  of AVI and ASF to DIV3.
551
- added -me option to set motion estimation method
552
  (default=log). suppressed redundant -hq option.
553
- added options -acodec and -vcodec to force a given codec (useful for
554
  AVI for example)
555
- fixed -an option
556
- improved dct_quantize speed
557
- factorized some motion estimation code
558

    
559

    
560
version 0.4.0:
561

    
562
- removing grab code from ffserver and moved it to ffmpeg. Added
563
  multistream support to ffmpeg.
564
- added timeshifting support for live feeds (option ?date=xxx in the
565
  URL)
566
- added high quality image resize code with polyphase filter (need
567
  mmx/see optimization). Enable multiple image size support in ffserver.
568
- added multi live feed support in ffserver
569
- suppressed master feature from ffserver (it should be done with an
570
  external program which opens the .ffm url and writes it to another
571
  ffserver)
572
- added preliminary support for video stream parsing (WAV and AVI half
573
  done). Added proper support for audio/video file conversion in
574
  ffmpeg.
575
- added preliminary support for video file sending from ffserver
576
- redesigning I/O subsystem: now using URL based input and output
577
  (see avio.h)
578
- added WAV format support
579
- added "tty user interface" to ffmpeg to stop grabbing gracefully
580
- added MMX/SSE optimizations to SAD (Sums of Absolutes Differences)
581
  (Juan J. Sierralta P. a.k.a. "Juanjo" <juanjo at atmlab.utfsm.cl>)
582
- added MMX DCT from mpeg2_movie 1.5 (Juanjo)
583
- added new motion estimation algorithms, log and phods (Juanjo)
584
- changed directories: libav for format handling, libavcodec for
585
  codecs

596
  real time at low resolution.
597
- fixed rounding problems which caused quality problems at high
598
  bitrates and large GOP size
599
