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

1300 - added MPEG demuxer (MPEG-1 and 2 compatible).
1302 - added prototype RM demuxer
1303 - added AC3 decoding (done with libac3 by Aaron Holtzman)
1304 - added decoding codec parameter guessing (.e.g. for MPEG, because the
1305 header does not include them)
1306 - fixed header generation in MPEG-1, AVI and ASF muxer: wmplayer can now
1307 play them (only tested video)
1308 - fixed H.263 white bug
1309 - fixed phase rounding in img resample filter
1310 - add MMX code for polyphase img resample filter
1311 - added CPU autodetection
1312 - added generic title/author/copyright/comment string handling (ASF and RM
1314 - added SWF demux to extract MP3 track (not usable yet because no MP3
1316 - added fractional frame rate support
1317 - codecs are no longer searched by read_header() (should fix ffserver
1323 - BGR24 patch (initial patch by Jeroen Vreeken <pe1rxq at amsat.org>)
1324 - fixed raw yuv output
1325 - added motion rounding support in MPEG-4
1326 - fixed motion bug rounding in MSMPEG4
1327 - added B-frame handling in video core
1328 - added full MPEG-1 decoding support
1329 - added partial (frame only) MPEG-2 support
1330 - changed the FOURCC code for H.263 to "U263" to be able to see the
1331 +AVI/H.263 file with the UB Video H.263+ decoder. MPlayer works with
1332 this +codec ;) (JuanJo).
1333 - Halfpel motion estimation after MB type selection (JuanJo)
1334 - added pgm and .Y.U.V output format
1335 - suppressed 'img:' protocol. Simply use: /tmp/test%d.[pgm|Y] as input or
1337 - added pgmpipe I/O format (original patch from Martin Aumueller
1338 <lists at reserv.at>, but changed completely since we use a format
1339 instead of a protocol)
1344 - added H.263/MPEG-4/MSMPEG4 decoding support. MPEG-4 decoding support
1345 (for OpenDivX) is almost complete: 8x8 MVs and rounding are
1346 missing. MSMPEG4 support is complete.
1347 - added prototype MPEG-1 decoder. Only I- and P-frames handled yet (it
1348 can decode ffmpeg MPEGs :-)).
1349 - added libavcodec API documentation (see apiexample.c).
1350 - fixed image polyphase bug (the bottom of some images could be
1352 - added support for non clipped motion vectors (decoding only)
1353 and image sizes non-multiple of 16
1354 - added support for AC prediction (decoding only)
1355 - added file overwrite confirmation (can be disabled with -y)
1356 - added custom size picture to H.263 using H.263+ (Juanjo)
1361 - added MSMPEG4 (aka DivX) compatible encoder. Changed default codec
1362 of AVI and ASF to DIV3.
1363 - added -me option to set motion estimation method
1364 (default=log). suppressed redundant -hq option.
1365 - added options -acodec and -vcodec to force a given codec (useful for
1368 - improved dct_quantize speed
1369 - factorized some motion estimation code
1374 - removing grab code from ffserver and moved it to ffmpeg. Added
1375 multistream support to ffmpeg.
1376 - added timeshifting support for live feeds (option ?date=xxx in the
1378 - added high quality image resize code with polyphase filter (need
1379 mmx/see optimization). Enable multiple image size support in ffserver.
1380 - added multi live feed support in ffserver
1381 - suppressed master feature from ffserver (it should be done with an
1382 external program which opens the .ffm url and writes it to another
1384 - added preliminary support for video stream parsing (WAV and AVI half
1385 done). Added proper support for audio/video file conversion in
1387 - added preliminary support for video file sending from ffserver
1388 - redesigning I/O subsystem: now using URL based input and output
1390 - added WAV format support
1391 - added "tty user interface" to ffmpeg to stop grabbing gracefully
1392 - added MMX/SSE optimizations to SAD (Sums of Absolutes Differences)
1393 (Juan J. Sierralta P. a.k.a. "Juanjo" <juanjo at atmlab.utfsm.cl>)
1394 - added MMX DCT from mpeg2_movie 1.5 (Juanjo)
1395 - added new motion estimation algorithms, log and phods (Juanjo)
1396 - changed directories: libav for format handling, libavcodec for
1402 - added stereo in MPEG audio encoder
1407 - added 'high quality' mode which use motion vectors. It can be used in
1408 real time at low resolution.
1409 - fixed rounding problems which caused quality problems at high
1410 bitrates and large GOP size
1413 version 0.3.2: small fixes
1419 version 0.3.1: added avi/divx support
1422 - added MPEG-4 codec compatible with OpenDivX. It is based on the H.263 codec
1423 - added sound for flash format (not tested)
1426 version 0.3: initial public release
