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

1311 - added prototype RM demuxer
1312 - added AC3 decoding (done with libac3 by Aaron Holtzman)
1313 - added decoding codec parameter guessing (.e.g. for MPEG, because the
1314 header does not include them)
1315 - fixed header generation in MPEG-1, AVI and ASF muxer: wmplayer can now
1316 play them (only tested video)
1317 - fixed H.263 white bug

1323 - added SWF demux to extract MP3 track (not usable yet because no MP3
1325 - added fractional frame rate support
1326 - codecs are no longer searched by read_header() (should fix ffserver
1332 - BGR24 patch (initial patch by Jeroen Vreeken <pe1rxq at amsat.org>)

1336 - added B-frame handling in video core
1337 - added full MPEG-1 decoding support
1338 - added partial (frame only) MPEG-2 support
1339 - changed the FOURCC code for H.263 to "U263" to be able to see the
1340 +AVI/H.263 file with the UB Video H.263+ decoder. MPlayer works with
1341 this +codec ;) (JuanJo).
1342 - Halfpel motion estimation after MB type selection (JuanJo)
1343 - added pgm and .Y.U.V output format
1344 - suppressed 'img:' protocol. Simply use: /tmp/test%d.[pgm|Y] as input or
1346 - added pgmpipe I/O format (original patch from Martin Aumueller
1347 <lists at reserv.at>, but changed completely since we use a format
1348 instead of a protocol)
1353 - added H.263/MPEG-4/MSMPEG4 decoding support. MPEG-4 decoding support
1354 (for OpenDivX) is almost complete: 8x8 MVs and rounding are
1355 missing. MSMPEG4 support is complete.
1356 - added prototype MPEG-1 decoder. Only I- and P-frames handled yet (it
1357 can decode ffmpeg MPEGs :-)).
1358 - added libavcodec API documentation (see apiexample.c).
1359 - fixed image polyphase bug (the bottom of some images could be
1361 - added support for non clipped motion vectors (decoding only)
1362 and image sizes non-multiple of 16
1363 - added support for AC prediction (decoding only)
1364 - added file overwrite confirmation (can be disabled with -y)
1365 - added custom size picture to H.263 using H.263+ (Juanjo)
1370 - added MSMPEG4 (aka DivX) compatible encoder. Changed default codec
1371 of AVI and ASF to DIV3.
1372 - added -me option to set motion estimation method
1373 (default=log). suppressed redundant -hq option.
1374 - added options -acodec and -vcodec to force a given codec (useful for
1377 - improved dct_quantize speed
1378 - factorized some motion estimation code
1383 - removing grab code from ffserver and moved it to ffmpeg. Added
1384 multistream support to ffmpeg.
1385 - added timeshifting support for live feeds (option ?date=xxx in the
1387 - added high quality image resize code with polyphase filter (need
1388 mmx/see optimization). Enable multiple image size support in ffserver.
1389 - added multi live feed support in ffserver
1390 - suppressed master feature from ffserver (it should be done with an
1391 external program which opens the .ffm url and writes it to another
1393 - added preliminary support for video stream parsing (WAV and AVI half
1394 done). Added proper support for audio/video file conversion in
1396 - added preliminary support for video file sending from ffserver
1397 - redesigning I/O subsystem: now using URL based input and output
1399 - added WAV format support
1400 - added "tty user interface" to ffmpeg to stop grabbing gracefully
1401 - added MMX/SSE optimizations to SAD (Sums of Absolutes Differences)
1402 (Juan J. Sierralta P. a.k.a. "Juanjo" <juanjo at atmlab.utfsm.cl>)
1403 - added MMX DCT from mpeg2_movie 1.5 (Juanjo)

1405 - changed directories: libav for format handling, libavcodec for
1411 - added stereo in MPEG audio encoder
1416 - added 'high quality' mode which use motion vectors. It can be used in
1417 real time at low resolution.
1418 - fixed rounding problems which caused quality problems at high
1419 bitrates and large GOP size
1422 version 0.3.2: small fixes
1428 version 0.3.1: added avi/divx support
