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

1296 - added AC3 decoding (done with libac3 by Aaron Holtzman)
1297 - added decoding codec parameter guessing (.e.g. for MPEG, because the
1298 header does not include them)
1299 - fixed header generation in MPEG-1, AVI and ASF muxer: wmplayer can now
1300 play them (only tested video)
1301 - fixed H.263 white bug
1302 - fixed phase rounding in img resample filter
1303 - add MMX code for polyphase img resample filter
1304 - added CPU autodetection
1305 - added generic title/author/copyright/comment string handling (ASF and RM
1307 - added SWF demux to extract MP3 track (not usable yet because no MP3
1309 - added fractional frame rate support
1310 - codecs are no longer searched by read_header() (should fix ffserver
1316 - BGR24 patch (initial patch by Jeroen Vreeken <pe1rxq at amsat.org>)
1317 - fixed raw yuv output
1318 - added motion rounding support in MPEG-4
1319 - fixed motion bug rounding in MSMPEG4
1320 - added B-frame handling in video core
1321 - added full MPEG-1 decoding support
1322 - added partial (frame only) MPEG-2 support
1323 - changed the FOURCC code for H.263 to "U263" to be able to see the
1324 +AVI/H.263 file with the UB Video H.263+ decoder. MPlayer works with
1325 this +codec ;) (JuanJo).
1326 - Halfpel motion estimation after MB type selection (JuanJo)
1327 - added pgm and .Y.U.V output format
1328 - suppressed 'img:' protocol. Simply use: /tmp/test%d.[pgm|Y] as input or
1330 - added pgmpipe I/O format (original patch from Martin Aumueller
1331 <lists at reserv.at>, but changed completely since we use a format
1332 instead of a protocol)
1337 - added H.263/MPEG-4/MSMPEG4 decoding support. MPEG-4 decoding support
1338 (for OpenDivX) is almost complete: 8x8 MVs and rounding are
1339 missing. MSMPEG4 support is complete.
1340 - added prototype MPEG-1 decoder. Only I- and P-frames handled yet (it
1341 can decode ffmpeg MPEGs :-)).
1342 - added libavcodec API documentation (see apiexample.c).
1343 - fixed image polyphase bug (the bottom of some images could be
1345 - added support for non clipped motion vectors (decoding only)
1346 and image sizes non-multiple of 16
1347 - added support for AC prediction (decoding only)
1348 - added file overwrite confirmation (can be disabled with -y)
1349 - added custom size picture to H.263 using H.263+ (Juanjo)
1354 - added MSMPEG4 (aka DivX) compatible encoder. Changed default codec
1355 of AVI and ASF to DIV3.
1356 - added -me option to set motion estimation method
1357 (default=log). suppressed redundant -hq option.
1358 - added options -acodec and -vcodec to force a given codec (useful for
1361 - improved dct_quantize speed
1362 - factorized some motion estimation code
1367 - removing grab code from ffserver and moved it to ffmpeg. Added
1368 multistream support to ffmpeg.
1369 - added timeshifting support for live feeds (option ?date=xxx in the
1371 - added high quality image resize code with polyphase filter (need
1372 mmx/see optimization). Enable multiple image size support in ffserver.
1373 - added multi live feed support in ffserver
1374 - suppressed master feature from ffserver (it should be done with an
1375 external program which opens the .ffm url and writes it to another
1377 - added preliminary support for video stream parsing (WAV and AVI half
1378 done). Added proper support for audio/video file conversion in
1380 - added preliminary support for video file sending from ffserver
1381 - redesigning I/O subsystem: now using URL based input and output
1383 - added WAV format support
1384 - added "tty user interface" to ffmpeg to stop grabbing gracefully
1385 - added MMX/SSE optimizations to SAD (Sums of Absolutes Differences)
1386 (Juan J. Sierralta P. a.k.a. "Juanjo" <juanjo at atmlab.utfsm.cl>)
1387 - added MMX DCT from mpeg2_movie 1.5 (Juanjo)
1388 - added new motion estimation algorithms, log and phods (Juanjo)
1389 - changed directories: libav for format handling, libavcodec for
1395 - added stereo in MPEG audio encoder
1400 - added 'high quality' mode which use motion vectors. It can be used in
1401 real time at low resolution.
1402 - fixed rounding problems which caused quality problems at high
1403 bitrates and large GOP size
1406 version 0.3.2: small fixes
1412 version 0.3.1: added avi/divx support
1415 - added MPEG-4 codec compatible with OpenDivX. It is based on the H.263 codec
1416 - added sound for flash format (not tested)
1419 version 0.3: initial public release
