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

1337 - added prototype RM demuxer
1338 - added AC3 decoding (done with libac3 by Aaron Holtzman)
1339 - added decoding codec parameter guessing (.e.g. for MPEG, because the
1340 header does not include them)

1349 - added SWF demux to extract MP3 track (not usable yet because no MP3
1351 - added fractional frame rate support
1352 - codecs are no longer searched by read_header() (should fix ffserver

1363 - added full MPEG-1 decoding support
1364 - added partial (frame only) MPEG-2 support
1365 - changed the FOURCC code for H.263 to "U263" to be able to see the
1366 +AVI/H.263 file with the UB Video H.263+ decoder. MPlayer works with
1367 this +codec ;) (JuanJo).
1368 - Halfpel motion estimation after MB type selection (JuanJo)
1369 - added pgm and .Y.U.V output format
1370 - suppressed 'img:' protocol. Simply use: /tmp/test%d.[pgm|Y] as input or
1372 - added pgmpipe I/O format (original patch from Martin Aumueller
1373 <lists at reserv.at>, but changed completely since we use a format
1374 instead of a protocol)
1379 - added H.263/MPEG-4/MSMPEG4 decoding support. MPEG-4 decoding support
1380 (for OpenDivX) is almost complete: 8x8 MVs and rounding are
1381 missing. MSMPEG4 support is complete.
1382 - added prototype MPEG-1 decoder. Only I- and P-frames handled yet (it
1383 can decode ffmpeg MPEGs :-)).

1399 (default=log). suppressed redundant -hq option.
1400 - added options -acodec and -vcodec to force a given codec (useful for
1403 - improved dct_quantize speed
1404 - factorized some motion estimation code
1409 - removing grab code from ffserver and moved it to ffmpeg. Added
1410 multistream support to ffmpeg.
1411 - added timeshifting support for live feeds (option ?date=xxx in the
1413 - added high quality image resize code with polyphase filter (need
1414 mmx/see optimization). Enable multiple image size support in ffserver.

1416 - suppressed master feature from ffserver (it should be done with an
1417 external program which opens the .ffm url and writes it to another
1419 - added preliminary support for video stream parsing (WAV and AVI half
1420 done). Added proper support for audio/video file conversion in
1422 - added preliminary support for video file sending from ffserver
