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

1347 - added prototype RM demuxer
1348 - added AC3 decoding (done with libac3 by Aaron Holtzman)
1349 - added decoding codec parameter guessing (.e.g. for MPEG, because the

1374 - added partial (frame only) MPEG-2 support
1375 - changed the FOURCC code for H.263 to "U263" to be able to see the
1376 +AVI/H.263 file with the UB Video H.263+ decoder. MPlayer works with
1377 this +codec ;) (JuanJo).
1378 - Halfpel motion estimation after MB type selection (JuanJo)
1379 - added pgm and .Y.U.V output format
1380 - suppressed 'img:' protocol. Simply use: /tmp/test%d.[pgm|Y] as input or
1382 - added pgmpipe I/O format (original patch from Martin Aumueller
1383 <lists at reserv.at>, but changed completely since we use a format
1384 instead of a protocol)
1389 - added H.263/MPEG-4/MSMPEG4 decoding support. MPEG-4 decoding support
1390 (for OpenDivX) is almost complete: 8x8 MVs and rounding are
1391 missing. MSMPEG4 support is complete.

1413 - improved dct_quantize speed
1414 - factorized some motion estimation code
1419 - removing grab code from ffserver and moved it to ffmpeg. Added
1420 multistream support to ffmpeg.
1421 - added timeshifting support for live feeds (option ?date=xxx in the

1424 mmx/see optimization). Enable multiple image size support in ffserver.

1426 - suppressed master feature from ffserver (it should be done with an
1427 external program which opens the .ffm url and writes it to another
1429 - added preliminary support for video stream parsing (WAV and AVI half
1430 done). Added proper support for audio/video file conversion in
