637 - Flash Screen Video 2 decoder
638 - lavfi input device added
639 - added avconv, which is almost the same for now, except
640 for a few incompatible changes in the options, which will hopefully make them
641 easier to use. The changes are:
642 * The options placement is now strictly enforced! While in theory the
643 options for ffmpeg should be given in [input options] -i INPUT [output
644 options] OUTPUT order, in practice it was possible to give output options
645 before the -i and it mostly worked. Except when it didn't - the behavior was
646 a bit inconsistent. In avconv, it is not possible to mix input and output
647 options. All non-global options are reset after an input or output filename.
648 * All per-file options are now truly per-file - they apply only to the next
649 input or output file and specifying different values for different files
650 will now work properly (notably -ss and -t options).
651 * All per-stream options are now truly per-stream - it is possible to
652 specify which stream(s) should a given option apply to. See the Stream
653 specifiers section in the avconv manual for details.
654 * In ffmpeg some options (like -newvideo/-newaudio/...) are irregular in the
655 sense that they're specified after the output filename instead of before,
656 like all other options. In avconv this irregularity is removed, all options
657 apply to the next input or output file.
658 * -newvideo/-newaudio/-newsubtitle options were removed. Not only were they
659 irregular and highly confusing, they were also redundant. In avconv the -map
660 option will create new streams in the output file and map input streams to
661 them. E.g. avconv -i INPUT -map 0 OUTPUT will create an output stream for
662 each stream in the first input file.
663 * The -map option now has slightly different and more powerful syntax:
664 + Colons (':') are used to separate file index/stream type/stream index
665 instead of dots. Comma (',') is used to separate the sync stream instead
666 of colon.. This is done for consistency with other options.
667 + It's possible to specify stream type. E.g. -map 0:a:2 creates an
668 output stream from the third input audio stream.
669 + Omitting the stream index now maps all the streams of the given type,
670 not just the first. E.g. -map 0:s creates output streams for all the
671 subtitle streams in the first input file.
672 + Since -map can now match multiple streams, negative mappings were
673 introduced. Negative mappings disable some streams from an already
674 defined map. E.g. '-map 0 -map -0:a:1' means 'create output streams for
675 all the stream in the first input file, except for the second audio
677 * There is a new option -c (or -codec) for choosing the decoder/encoder to
678 use, which makes it possible to precisely specify target stream(s) consistently with
679 other options. E.g. -c:v lib264 sets the codec for all video streams, -c:a:0
680 libvorbis sets the codec for the first audio stream and -c copy copies all
681 the streams without reencoding. Old -vcodec/-acodec/-scodec options are now
683 * It is now possible to precisely specify which stream should an AVOption
684 apply to. E.g. -b:v:0 2M sets the bitrate for the first video stream, while
685 -b:a 128k sets the bitrate for all audio streams. Note that the old -ab 128k
686 syntax is deprecated and will stop working soon.
687 * -map_chapters now takes only an input file index and applies to the next
688 output file. This is consistent with how all the other options work.
689 * -map_metadata now takes only an input metadata specifier and applies to
690 the next output file. Output metadata specifier is now part of the option
691 name, similarly to the AVOptions/map/codec feature above.
692 * -metadata can now be used to set metadata on streams and chapters, e.g.
693 -metadata:s:1 language=eng sets the language of the first stream to 'eng'.
694 This made -vlang/-alang/-slang options redundant, so they were removed.
695 * -qscale option now uses stream specifiers and applies to all streams, not
696 just video. I.e. plain -qscale number would now apply to all streams. To get
697 the old behavior, use -qscale:v. Also there is now a shortcut -q for -qscale
698 and -aq is now an alias for -q:a.
699 * -vbsf/-absf/-sbsf options were removed and replaced by a -bsf option which
700 uses stream specifiers. Use -bsf:v/a/s instead of the old options.
701 * -itsscale option now uses stream specifiers, so its argument is only the
703 * -intra option was removed, use -g 0 for the same effect.
704 * -psnr option was removed, use -flags +psnr for the same effect.
705 * -vf option is now an alias to the new -filter option, which uses stream specifiers.
706 * -vframes/-aframes/-dframes options are now aliases to the new -frames option.
707 * -vtag/-atag/-stag options are now aliases to the new -tag option.

1345 - added prototype RM demuxer
1346 - added AC3 decoding (done with libac3 by Aaron Holtzman)
1347 - added decoding codec parameter guessing (.e.g. for MPEG, because the

1372 - added partial (frame only) MPEG-2 support
1373 - changed the FOURCC code for H.263 to "U263" to be able to see the
1374 +AVI/H.263 file with the UB Video H.263+ decoder. MPlayer works with
1375 this +codec ;) (JuanJo).
1376 - Halfpel motion estimation after MB type selection (JuanJo)
1377 - added pgm and .Y.U.V output format
1378 - suppressed 'img:' protocol. Simply use: /tmp/test%d.[pgm|Y] as input or
1380 - added pgmpipe I/O format (original patch from Martin Aumueller
1381 <lists at reserv.at>, but changed completely since we use a format
1382 instead of a protocol)
1387 - added H.263/MPEG-4/MSMPEG4 decoding support. MPEG-4 decoding support
1388 (for OpenDivX) is almost complete: 8x8 MVs and rounding are
1389 missing. MSMPEG4 support is complete.

1408 - added options -acodec and -vcodec to force a given codec (useful for
1411 - improved dct_quantize speed
1412 - factorized some motion estimation code
1417 - removing grab code from ffserver and moved it to ffmpeg. Added
1418 multistream support to ffmpeg.
1419 - added timeshifting support for live feeds (option ?date=xxx in the

1422 mmx/see optimization). Enable multiple image size support in ffserver.

1424 - suppressed master feature from ffserver (it should be done with an
1425 external program which opens the .ffm url and writes it to another
1427 - added preliminary support for video stream parsing (WAV and AVI half
1428 done). Added proper support for audio/video file conversion in
