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

1350 - added prototype RM demuxer
1351 - added AC3 decoding (done with libac3 by Aaron Holtzman)
1352 - added decoding codec parameter guessing (.e.g. for MPEG, because the

1377 - added partial (frame only) MPEG-2 support
1378 - changed the FOURCC code for H.263 to "U263" to be able to see the
1379 +AVI/H.263 file with the UB Video H.263+ decoder. MPlayer works with
1380 this +codec ;) (JuanJo).
1381 - Halfpel motion estimation after MB type selection (JuanJo)
1382 - added pgm and .Y.U.V output format
1383 - suppressed 'img:' protocol. Simply use: /tmp/test%d.[pgm|Y] as input or
1385 - added pgmpipe I/O format (original patch from Martin Aumueller
1386 <lists at reserv.at>, but changed completely since we use a format
1387 instead of a protocol)
1392 - added H.263/MPEG-4/MSMPEG4 decoding support. MPEG-4 decoding support
1393 (for OpenDivX) is almost complete: 8x8 MVs and rounding are
1394 missing. MSMPEG4 support is complete.

1413 - added options -acodec and -vcodec to force a given codec (useful for
1416 - improved dct_quantize speed
1417 - factorized some motion estimation code
1422 - removing grab code from ffserver and moved it to ffmpeg. Added
1423 multistream support to ffmpeg.
1424 - added timeshifting support for live feeds (option ?date=xxx in the

1427 mmx/see optimization). Enable multiple image size support in ffserver.

1429 - suppressed master feature from ffserver (it should be done with an
1430 external program which opens the .ffm url and writes it to another
1432 - added preliminary support for video stream parsing (WAV and AVI half
1433 done). Added proper support for audio/video file conversion in
