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

1380 - added partial (frame only) MPEG-2 support
1381 - changed the FOURCC code for H.263 to "U263" to be able to see the
1382 +AVI/H.263 file with the UB Video H.263+ decoder. MPlayer works with
1383 this +codec ;) (JuanJo).
1384 - Halfpel motion estimation after MB type selection (JuanJo)
1385 - added pgm and .Y.U.V output format
1386 - suppressed 'img:' protocol. Simply use: /tmp/test%d.[pgm|Y] as input or
1388 - added pgmpipe I/O format (original patch from Martin Aumueller
1389 <lists at reserv.at>, but changed completely since we use a format
1390 instead of a protocol)
1395 - added H.263/MPEG-4/MSMPEG4 decoding support. MPEG-4 decoding support
1396 (for OpenDivX) is almost complete: 8x8 MVs and rounding are
1397 missing. MSMPEG4 support is complete.

1416 - added options -acodec and -vcodec to force a given codec (useful for
1419 - improved dct_quantize speed
1420 - factorized some motion estimation code
1425 - removing grab code from ffserver and moved it to ffmpeg. Added
1426 multistream support to ffmpeg.
1427 - added timeshifting support for live feeds (option ?date=xxx in the

1430 mmx/see optimization). Enable multiple image size support in ffserver.

1432 - suppressed master feature from ffserver (it should be done with an
1433 external program which opens the .ffm url and writes it to another
1435 - added preliminary support for video stream parsing (WAV and AVI half
1436 done). Added proper support for audio/video file conversion in
