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

1306 - added prototype RM demuxer
1307 - added AC3 decoding (done with libac3 by Aaron Holtzman)
1308 - added decoding codec parameter guessing (.e.g. for MPEG, because the
1309 header does not include them)
1310 - fixed header generation in MPEG-1, AVI and ASF muxer: wmplayer can now
1311 play them (only tested video)
1312 - fixed H.263 white bug
1313 - fixed phase rounding in img resample filter
1314 - add MMX code for polyphase img resample filter

1316 - added generic title/author/copyright/comment string handling (ASF and RM
1318 - added SWF demux to extract MP3 track (not usable yet because no MP3
1320 - added fractional frame rate support
1321 - codecs are no longer searched by read_header() (should fix ffserver
1327 - BGR24 patch (initial patch by Jeroen Vreeken <pe1rxq at amsat.org>)
1328 - fixed raw yuv output
1329 - added motion rounding support in MPEG-4
1330 - fixed motion bug rounding in MSMPEG4
1331 - added B-frame handling in video core
1332 - added full MPEG-1 decoding support
1333 - added partial (frame only) MPEG-2 support
1334 - changed the FOURCC code for H.263 to "U263" to be able to see the
1335 +AVI/H.263 file with the UB Video H.263+ decoder. MPlayer works with
1336 this +codec ;) (JuanJo).
1337 - Halfpel motion estimation after MB type selection (JuanJo)
1338 - added pgm and .Y.U.V output format
1339 - suppressed 'img:' protocol. Simply use: /tmp/test%d.[pgm|Y] as input or
1341 - added pgmpipe I/O format (original patch from Martin Aumueller
1342 <lists at reserv.at>, but changed completely since we use a format
1343 instead of a protocol)
1348 - added H.263/MPEG-4/MSMPEG4 decoding support. MPEG-4 decoding support
1349 (for OpenDivX) is almost complete: 8x8 MVs and rounding are
1350 missing. MSMPEG4 support is complete.
1351 - added prototype MPEG-1 decoder. Only I- and P-frames handled yet (it
1352 can decode ffmpeg MPEGs :-)).
1353 - added libavcodec API documentation (see apiexample.c).
1354 - fixed image polyphase bug (the bottom of some images could be
1356 - added support for non clipped motion vectors (decoding only)
1357 and image sizes non-multiple of 16
1358 - added support for AC prediction (decoding only)
1359 - added file overwrite confirmation (can be disabled with -y)
1360 - added custom size picture to H.263 using H.263+ (Juanjo)
1365 - added MSMPEG4 (aka DivX) compatible encoder. Changed default codec
1366 of AVI and ASF to DIV3.
1367 - added -me option to set motion estimation method
1368 (default=log). suppressed redundant -hq option.
1369 - added options -acodec and -vcodec to force a given codec (useful for
1372 - improved dct_quantize speed
1373 - factorized some motion estimation code
1378 - removing grab code from ffserver and moved it to ffmpeg. Added
1379 multistream support to ffmpeg.
1380 - added timeshifting support for live feeds (option ?date=xxx in the
1382 - added high quality image resize code with polyphase filter (need
1383 mmx/see optimization). Enable multiple image size support in ffserver.
1384 - added multi live feed support in ffserver
1385 - suppressed master feature from ffserver (it should be done with an
1386 external program which opens the .ffm url and writes it to another
1388 - added preliminary support for video stream parsing (WAV and AVI half
1389 done). Added proper support for audio/video file conversion in
1391 - added preliminary support for video file sending from ffserver
1392 - redesigning I/O subsystem: now using URL based input and output
1394 - added WAV format support
1395 - added "tty user interface" to ffmpeg to stop grabbing gracefully
1396 - added MMX/SSE optimizations to SAD (Sums of Absolutes Differences)
1397 (Juan J. Sierralta P. a.k.a. "Juanjo" <juanjo at atmlab.utfsm.cl>)
1398 - added MMX DCT from mpeg2_movie 1.5 (Juanjo)
1399 - added new motion estimation algorithms, log and phods (Juanjo)
1400 - changed directories: libav for format handling, libavcodec for
1406 - added stereo in MPEG audio encoder
1411 - added 'high quality' mode which use motion vectors. It can be used in
1412 real time at low resolution.
1413 - fixed rounding problems which caused quality problems at high
1414 bitrates and large GOP size
1417 version 0.3.2: small fixes
1423 version 0.3.1: added avi/divx support
