  output.
481
- added pgmpipe I/O format (original patch from Martin Aumueller
482
  <lists at reserv.at>, but changed completely since we use a format
483
  instead of a protocol)
484

    
485

    
486

    
487
version 0.4.2:
488

    
489
- added H.263/MPEG-4/MSMPEG4 decoding support. MPEG-4 decoding support
490
  (for OpenDivX) is almost complete: 8x8 MVs and rounding are
491
  missing. MSMPEG4 support is complete.
492
- added prototype MPEG-1 decoder. Only I- and P-frames handled yet (it
493
  can decode ffmpeg MPEGs :-)).
494
- added libavcodec API documentation (see apiexample.c).
495
- fixed image polyphase bug (the bottom of some images could be
496
  greenish)
497
- added support for non clipped motion vectors (decoding only)
498
  and image sizes non-multiple of 16
499
- added support for AC prediction (decoding only)
500
- added file overwrite confirmation (can be disabled with -y)
501
- added custom size picture to H.263 using H.263+ (Juanjo)
502

    
503

    
504
version 0.4.1:
505

    
506
- added MSMPEG4 (aka DivX) compatible encoder. Changed default codec
507
  of AVI and ASF to DIV3.
508
- added -me option to set motion estimation method
509
  (default=log). suppressed redundant -hq option.
510
- added options -acodec and -vcodec to force a given codec (useful for
511
  AVI for example)
512
- fixed -an option
513
- improved dct_quantize speed
514
- factorized some motion estimation code
515

    
516

    
517

    
518
version 0.4.0:
519

    
520
- removing grab code from ffserver and moved it to ffmpeg. Added
521
  multistream support to ffmpeg.
522
- added timeshifting support for live feeds (option ?date=xxx in the
523
  URL)
524
- added high quality image resize code with polyphase filter (need
525
  mmx/see optimization). Enable multiple image size support in ffserver.
526
- added multi live feed support in ffserver
527
- suppressed master feature from ffserver (it should be done with an
528
  external program which opens the .ffm url and writes it to another
529
  ffserver)
530
- added preliminary support for video stream parsing (WAV and AVI half
531
  done). Added proper support for audio/video file conversion in
532
  ffmpeg.
533
- added preliminary support for video file sending from ffserver
534
- redesigning I/O subsystem: now using URL based input and output
535
  (see avio.h)
536
- added WAV format support
537
- added "tty user interface" to ffmpeg to stop grabbing gracefully
538
- added MMX/SSE optimizations to SAD (Sums of Absolutes Differences)
539
  (Juan J. Sierralta P. a.k.a. "Juanjo" <juanjo at atmlab.utfsm.cl>)
540
- added MMX DCT from mpeg2_movie 1.5 (Juanjo)
541
- added new motion estimation algorithms, log and phods (Juanjo)
542
- changed directories: libav for format handling, libavcodec for
543
  codecs

552

    
553
version 0.3.3:
554

    
555
- added 'high quality' mode which use motion vectors. It can be used in
556
  real time at low resolution.
557
- fixed rounding problems which caused quality problems at high
558
  bitrates and large GOP size
559
