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

685 uses stream specifiers. Use -bsf:v/a/s instead of the old options.

688 * -intra option was removed, use -g 0 for the same effect.
689 * -psnr option was removed, use -flags +psnr for the same effect.
690 * -vf option is now an alias to the new -filter option, which uses stream specifiers.
691 * -vframes/-aframes/-dframes options are now aliases to the new -frames option.

1330 - added prototype RM demuxer
1331 - added AC3 decoding (done with libac3 by Aaron Holtzman)
1332 - added decoding codec parameter guessing (.e.g. for MPEG, because the
1333 header does not include them)
1334 - fixed header generation in MPEG-1, AVI and ASF muxer: wmplayer can now
1335 play them (only tested video)
1336 - fixed H.263 white bug
1337 - fixed phase rounding in img resample filter
1338 - add MMX code for polyphase img resample filter

1340 - added generic title/author/copyright/comment string handling (ASF and RM
1342 - added SWF demux to extract MP3 track (not usable yet because no MP3
1344 - added fractional frame rate support
1345 - codecs are no longer searched by read_header() (should fix ffserver
1351 - BGR24 patch (initial patch by Jeroen Vreeken <pe1rxq at amsat.org>)

1355 - added B-frame handling in video core
1356 - added full MPEG-1 decoding support
1357 - added partial (frame only) MPEG-2 support
1358 - changed the FOURCC code for H.263 to "U263" to be able to see the
1359 +AVI/H.263 file with the UB Video H.263+ decoder. MPlayer works with
1360 this +codec ;) (JuanJo).
1361 - Halfpel motion estimation after MB type selection (JuanJo)
1362 - added pgm and .Y.U.V output format
1363 - suppressed 'img:' protocol. Simply use: /tmp/test%d.[pgm|Y] as input or
1365 - added pgmpipe I/O format (original patch from Martin Aumueller
1366 <lists at reserv.at>, but changed completely since we use a format
1367 instead of a protocol)
1372 - added H.263/MPEG-4/MSMPEG4 decoding support. MPEG-4 decoding support
1373 (for OpenDivX) is almost complete: 8x8 MVs and rounding are
1374 missing. MSMPEG4 support is complete.
1375 - added prototype MPEG-1 decoder. Only I- and P-frames handled yet (it
1376 can decode ffmpeg MPEGs :-)).

1381 and image sizes non-multiple of 16
1382 - added support for AC prediction (decoding only)
1383 - added file overwrite confirmation (can be disabled with -y)
1384 - added custom size picture to H.263 using H.263+ (Juanjo)
1389 - added MSMPEG4 (aka DivX) compatible encoder. Changed default codec
1390 of AVI and ASF to DIV3.
1391 - added -me option to set motion estimation method
1392 (default=log). suppressed redundant -hq option.
1393 - added options -acodec and -vcodec to force a given codec (useful for
1396 - improved dct_quantize speed
1397 - factorized some motion estimation code
1402 - removing grab code from ffserver and moved it to ffmpeg. Added
1403 multistream support to ffmpeg.
1404 - added timeshifting support for live feeds (option ?date=xxx in the
1406 - added high quality image resize code with polyphase filter (need
1407 mmx/see optimization). Enable multiple image size support in ffserver.
1408 - added multi live feed support in ffserver
1409 - suppressed master feature from ffserver (it should be done with an
1410 external program which opens the .ffm url and writes it to another
1412 - added preliminary support for video stream parsing (WAV and AVI half
1413 done). Added proper support for audio/video file conversion in
1415 - added preliminary support for video file sending from ffserver
1416 - redesigning I/O subsystem: now using URL based input and output
1418 - added WAV format support
1419 - added "tty user interface" to ffmpeg to stop grabbing gracefully
1420 - added MMX/SSE optimizations to SAD (Sums of Absolutes Differences)
1421 (Juan J. Sierralta P. a.k.a. "Juanjo" <juanjo at atmlab.utfsm.cl>)

1424 - changed directories: libav for format handling, libavcodec for
1430 - added stereo in MPEG audio encoder
1435 - added 'high quality' mode which use motion vectors. It can be used in
1436 real time at low resolution.
1437 - fixed rounding problems which caused quality problems at high
1438 bitrates and large GOP size
1441 version 0.3.2: small fixes
