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

1328 - added prototype RM demuxer
1329 - added AC3 decoding (done with libac3 by Aaron Holtzman)
1330 - added decoding codec parameter guessing (.e.g. for MPEG, because the
1331 header does not include them)
1332 - fixed header generation in MPEG-1, AVI and ASF muxer: wmplayer can now
1333 play them (only tested video)
1334 - fixed H.263 white bug

1340 - added SWF demux to extract MP3 track (not usable yet because no MP3
1342 - added fractional frame rate support
1343 - codecs are no longer searched by read_header() (should fix ffserver
1349 - BGR24 patch (initial patch by Jeroen Vreeken <pe1rxq at amsat.org>)

1353 - added B-frame handling in video core
1354 - added full MPEG-1 decoding support
1355 - added partial (frame only) MPEG-2 support
1356 - changed the FOURCC code for H.263 to "U263" to be able to see the
1357 +AVI/H.263 file with the UB Video H.263+ decoder. MPlayer works with
1358 this +codec ;) (JuanJo).
1359 - Halfpel motion estimation after MB type selection (JuanJo)
1360 - added pgm and .Y.U.V output format
1361 - suppressed 'img:' protocol. Simply use: /tmp/test%d.[pgm|Y] as input or
1363 - added pgmpipe I/O format (original patch from Martin Aumueller
1364 <lists at reserv.at>, but changed completely since we use a format
1365 instead of a protocol)
1370 - added H.263/MPEG-4/MSMPEG4 decoding support. MPEG-4 decoding support
1371 (for OpenDivX) is almost complete: 8x8 MVs and rounding are
1372 missing. MSMPEG4 support is complete.
1373 - added prototype MPEG-1 decoder. Only I- and P-frames handled yet (it
1374 can decode ffmpeg MPEGs :-)).

1381 - added file overwrite confirmation (can be disabled with -y)
1382 - added custom size picture to H.263 using H.263+ (Juanjo)
1387 - added MSMPEG4 (aka DivX) compatible encoder. Changed default codec
1388 of AVI and ASF to DIV3.
1389 - added -me option to set motion estimation method
1390 (default=log). suppressed redundant -hq option.
1391 - added options -acodec and -vcodec to force a given codec (useful for
1394 - improved dct_quantize speed
1395 - factorized some motion estimation code
1400 - removing grab code from ffserver and moved it to ffmpeg. Added
1401 multistream support to ffmpeg.
1402 - added timeshifting support for live feeds (option ?date=xxx in the
1404 - added high quality image resize code with polyphase filter (need
1405 mmx/see optimization). Enable multiple image size support in ffserver.
1406 - added multi live feed support in ffserver
1407 - suppressed master feature from ffserver (it should be done with an
1408 external program which opens the .ffm url and writes it to another
1410 - added preliminary support for video stream parsing (WAV and AVI half
1411 done). Added proper support for audio/video file conversion in
1413 - added preliminary support for video file sending from ffserver
1414 - redesigning I/O subsystem: now using URL based input and output
1416 - added WAV format support
1417 - added "tty user interface" to ffmpeg to stop grabbing gracefully
1418 - added MMX/SSE optimizations to SAD (Sums of Absolutes Differences)
1419 (Juan J. Sierralta P. a.k.a. "Juanjo" <juanjo at atmlab.utfsm.cl>)
1420 - added MMX DCT from mpeg2_movie 1.5 (Juanjo)

1422 - changed directories: libav for format handling, libavcodec for
1428 - added stereo in MPEG audio encoder
1433 - added 'high quality' mode which use motion vectors. It can be used in
1434 real time at low resolution.
1435 - fixed rounding problems which caused quality problems at high
1436 bitrates and large GOP size
1439 version 0.3.2: small fixes
1445 version 0.3.1: added avi/divx support
