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

1376 - added partial (frame only) MPEG-2 support
1377 - changed the FOURCC code for H.263 to "U263" to be able to see the
1378 +AVI/H.263 file with the UB Video H.263+ decoder. MPlayer works with
1379 this +codec ;) (JuanJo).
1380 - Halfpel motion estimation after MB type selection (JuanJo)
1381 - added pgm and .Y.U.V output format
1382 - suppressed 'img:' protocol. Simply use: /tmp/test%d.[pgm|Y] as input or
1384 - added pgmpipe I/O format (original patch from Martin Aumueller
1385 <lists at reserv.at>, but changed completely since we use a format
1386 instead of a protocol)
1391 - added H.263/MPEG-4/MSMPEG4 decoding support. MPEG-4 decoding support
1392 (for OpenDivX) is almost complete: 8x8 MVs and rounding are
1393 missing. MSMPEG4 support is complete.

1415 - improved dct_quantize speed
1416 - factorized some motion estimation code
1421 - removing grab code from ffserver and moved it to ffmpeg. Added
1422 multistream support to ffmpeg.
1423 - added timeshifting support for live feeds (option ?date=xxx in the

1426 mmx/see optimization). Enable multiple image size support in ffserver.

1428 - suppressed master feature from ffserver (it should be done with an
1429 external program which opens the .ffm url and writes it to another

1432 done). Added proper support for audio/video file conversion in
