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

1326 - added prototype RM demuxer
1327 - added AC3 decoding (done with libac3 by Aaron Holtzman)
1328 - added decoding codec parameter guessing (.e.g. for MPEG, because the
1329 header does not include them)
1330 - fixed header generation in MPEG-1, AVI and ASF muxer: wmplayer can now
1331 play them (only tested video)
1332 - fixed H.263 white bug

1338 - added SWF demux to extract MP3 track (not usable yet because no MP3
1340 - added fractional frame rate support
1341 - codecs are no longer searched by read_header() (should fix ffserver
1347 - BGR24 patch (initial patch by Jeroen Vreeken <pe1rxq at amsat.org>)

1351 - added B-frame handling in video core
1352 - added full MPEG-1 decoding support
1353 - added partial (frame only) MPEG-2 support
1354 - changed the FOURCC code for H.263 to "U263" to be able to see the
1355 +AVI/H.263 file with the UB Video H.263+ decoder. MPlayer works with
1356 this +codec ;) (JuanJo).
1357 - Halfpel motion estimation after MB type selection (JuanJo)
1358 - added pgm and .Y.U.V output format
1359 - suppressed 'img:' protocol. Simply use: /tmp/test%d.[pgm|Y] as input or
1361 - added pgmpipe I/O format (original patch from Martin Aumueller
1362 <lists at reserv.at>, but changed completely since we use a format
1363 instead of a protocol)
1368 - added H.263/MPEG-4/MSMPEG4 decoding support. MPEG-4 decoding support
1369 (for OpenDivX) is almost complete: 8x8 MVs and rounding are
1370 missing. MSMPEG4 support is complete.
1371 - added prototype MPEG-1 decoder. Only I- and P-frames handled yet (it
1372 can decode ffmpeg MPEGs :-)).

1377 and image sizes non-multiple of 16
1378 - added support for AC prediction (decoding only)
1379 - added file overwrite confirmation (can be disabled with -y)
1380 - added custom size picture to H.263 using H.263+ (Juanjo)
1385 - added MSMPEG4 (aka DivX) compatible encoder. Changed default codec
1386 of AVI and ASF to DIV3.
1387 - added -me option to set motion estimation method
1388 (default=log). suppressed redundant -hq option.
1389 - added options -acodec and -vcodec to force a given codec (useful for
1392 - improved dct_quantize speed
1393 - factorized some motion estimation code
1398 - removing grab code from ffserver and moved it to ffmpeg. Added
1399 multistream support to ffmpeg.
1400 - added timeshifting support for live feeds (option ?date=xxx in the
1402 - added high quality image resize code with polyphase filter (need
1403 mmx/see optimization). Enable multiple image size support in ffserver.
1404 - added multi live feed support in ffserver
1405 - suppressed master feature from ffserver (it should be done with an
1406 external program which opens the .ffm url and writes it to another
1408 - added preliminary support for video stream parsing (WAV and AVI half
1409 done). Added proper support for audio/video file conversion in
1411 - added preliminary support for video file sending from ffserver
1412 - redesigning I/O subsystem: now using URL based input and output
1414 - added WAV format support
1415 - added "tty user interface" to ffmpeg to stop grabbing gracefully
1416 - added MMX/SSE optimizations to SAD (Sums of Absolutes Differences)
1417 (Juan J. Sierralta P. a.k.a. "Juanjo" <juanjo at atmlab.utfsm.cl>)
1418 - added MMX DCT from mpeg2_movie 1.5 (Juanjo)
1419 - added new motion estimation algorithms, log and phods (Juanjo)
1420 - changed directories: libav for format handling, libavcodec for
1426 - added stereo in MPEG audio encoder
1431 - added 'high quality' mode which use motion vectors. It can be used in
1432 real time at low resolution.
1433 - fixed rounding problems which caused quality problems at high
1434 bitrates and large GOP size
1437 version 0.3.2: small fixes
1443 version 0.3.1: added avi/divx support
