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

1333 - added prototype RM demuxer
1334 - added AC3 decoding (done with libac3 by Aaron Holtzman)
1335 - added decoding codec parameter guessing (.e.g. for MPEG, because the
1336 header does not include them)

1345 - added SWF demux to extract MP3 track (not usable yet because no MP3
1347 - added fractional frame rate support

1359 - added full MPEG-1 decoding support
1360 - added partial (frame only) MPEG-2 support
1361 - changed the FOURCC code for H.263 to "U263" to be able to see the
1362 +AVI/H.263 file with the UB Video H.263+ decoder. MPlayer works with
1363 this +codec ;) (JuanJo).
1364 - Halfpel motion estimation after MB type selection (JuanJo)
1365 - added pgm and .Y.U.V output format
1366 - suppressed 'img:' protocol. Simply use: /tmp/test%d.[pgm|Y] as input or
1368 - added pgmpipe I/O format (original patch from Martin Aumueller
1369 <lists at reserv.at>, but changed completely since we use a format
1370 instead of a protocol)
1375 - added H.263/MPEG-4/MSMPEG4 decoding support. MPEG-4 decoding support
1376 (for OpenDivX) is almost complete: 8x8 MVs and rounding are
1377 missing. MSMPEG4 support is complete.
1378 - added prototype MPEG-1 decoder. Only I- and P-frames handled yet (it
1379 can decode ffmpeg MPEGs :-)).

1396 - added options -acodec and -vcodec to force a given codec (useful for
1399 - improved dct_quantize speed
1400 - factorized some motion estimation code
1405 - removing grab code from ffserver and moved it to ffmpeg. Added
1406 multistream support to ffmpeg.
1407 - added timeshifting support for live feeds (option ?date=xxx in the
1409 - added high quality image resize code with polyphase filter (need
1410 mmx/see optimization). Enable multiple image size support in ffserver.

1412 - suppressed master feature from ffserver (it should be done with an
1413 external program which opens the .ffm url and writes it to another
1415 - added preliminary support for video stream parsing (WAV and AVI half
1416 done). Added proper support for audio/video file conversion in
1418 - added preliminary support for video file sending from ffserver
