504
- added prototype RM demuxer
505

506
- added decoding codec parameter guessing (.e.g. for MPEG, because the
507
  header does not include them)
508

509
  play them (only tested video)
510
- fixed H.263 white bug
511
- fixed phase rounding in img resample filter
512
- add MMX code for polyphase img resample filter

517
  decoder)
518
- added fractional frame rate support
519

520
  segfault)
521

    
522

    
523
version 0.4.3:
524

    
525

531
- added partial (frame only) MPEG-2 support
532
- changed the FOURCC code for H.263 to "U263" to be able to see the
533
  +AVI/H.263 file with the UB Video H.263+ decoder. MPlayer works with
534
  this +codec ;) (JuanJo).
535
- Halfpel motion estimation after MB type selection (JuanJo)
536
- added pgm and .Y.U.V output format
537
- suppressed 'img:' protocol. Simply use: /tmp/test%d.[pgm|Y] as input or
538
  output.
539
- added pgmpipe I/O format (original patch from Martin Aumueller
540
  <lists at reserv.at>, but changed completely since we use a format
541
  instead of a protocol)
542

    
543

    
544
version 0.4.2:
545

    
546
- added H.263/MPEG-4/MSMPEG4 decoding support. MPEG-4 decoding support
547
  (for OpenDivX) is almost complete: 8x8 MVs and rounding are
548
  missing. MSMPEG4 support is complete.
549
- added prototype MPEG-1 decoder. Only I- and P-frames handled yet (it
550
  can decode ffmpeg MPEGs :-)).
551
- added libavcodec API documentation (see apiexample.c).
552
- fixed image polyphase bug (the bottom of some images could be
553
  greenish)
554
- added support for non clipped motion vectors (decoding only)
555
  and image sizes non-multiple of 16
556
- added support for AC prediction (decoding only)
557
- added file overwrite confirmation (can be disabled with -y)
558
- added custom size picture to H.263 using H.263+ (Juanjo)
559

    
560

    
561
version 0.4.1:
562

    
563
- added MSMPEG4 (aka DivX) compatible encoder. Changed default codec
564
  of AVI and ASF to DIV3.
565
- added -me option to set motion estimation method
566
  (default=log). suppressed redundant -hq option.
567
- added options -acodec and -vcodec to force a given codec (useful for
568
  AVI for example)
569
- fixed -an option
570
- improved dct_quantize speed
571
- factorized some motion estimation code
572

    
573

    
574
version 0.4.0:
575

    
576
- removing grab code from ffserver and moved it to ffmpeg. Added
577
  multistream support to ffmpeg.
578
- added timeshifting support for live feeds (option ?date=xxx in the
579
  URL)
580
- added high quality image resize code with polyphase filter (need
581
  mmx/see optimization). Enable multiple image size support in ffserver.
582
- added multi live feed support in ffserver
583
- suppressed master feature from ffserver (it should be done with an
584
  external program which opens the .ffm url and writes it to another
585
  ffserver)
586
- added preliminary support for video stream parsing (WAV and AVI half
587
  done). Added proper support for audio/video file conversion in
588
  ffmpeg.
589
- added preliminary support for video file sending from ffserver
590
- redesigning I/O subsystem: now using URL based input and output
591
  (see avio.h)
592
- added WAV format support
593
- added "tty user interface" to ffmpeg to stop grabbing gracefully
594

596
- added MMX DCT from mpeg2_movie 1.5 (Juanjo)
597
