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

1308 - added prototype RM demuxer
1309 - added AC3 decoding (done with libac3 by Aaron Holtzman)
1310 - added decoding codec parameter guessing (.e.g. for MPEG, because the
1311 header does not include them)
1312 - fixed header generation in MPEG-1, AVI and ASF muxer: wmplayer can now
1313 play them (only tested video)
1314 - fixed H.263 white bug
1315 - fixed phase rounding in img resample filter
1316 - add MMX code for polyphase img resample filter

1318 - added generic title/author/copyright/comment string handling (ASF and RM
1320 - added SWF demux to extract MP3 track (not usable yet because no MP3
1322 - added fractional frame rate support
1323 - codecs are no longer searched by read_header() (should fix ffserver
1329 - BGR24 patch (initial patch by Jeroen Vreeken <pe1rxq at amsat.org>)

1331 - added motion rounding support in MPEG-4
1332 - fixed motion bug rounding in MSMPEG4
1333 - added B-frame handling in video core
1334 - added full MPEG-1 decoding support
1335 - added partial (frame only) MPEG-2 support
1336 - changed the FOURCC code for H.263 to "U263" to be able to see the
1337 +AVI/H.263 file with the UB Video H.263+ decoder. MPlayer works with
1338 this +codec ;) (JuanJo).
1339 - Halfpel motion estimation after MB type selection (JuanJo)
1340 - added pgm and .Y.U.V output format
1341 - suppressed 'img:' protocol. Simply use: /tmp/test%d.[pgm|Y] as input or
1343 - added pgmpipe I/O format (original patch from Martin Aumueller
1344 <lists at reserv.at>, but changed completely since we use a format
1345 instead of a protocol)
1350 - added H.263/MPEG-4/MSMPEG4 decoding support. MPEG-4 decoding support
1351 (for OpenDivX) is almost complete: 8x8 MVs and rounding are
1352 missing. MSMPEG4 support is complete.
1353 - added prototype MPEG-1 decoder. Only I- and P-frames handled yet (it
1354 can decode ffmpeg MPEGs :-)).
1355 - added libavcodec API documentation (see apiexample.c).
1356 - fixed image polyphase bug (the bottom of some images could be
1358 - added support for non clipped motion vectors (decoding only)
1359 and image sizes non-multiple of 16
1360 - added support for AC prediction (decoding only)
1361 - added file overwrite confirmation (can be disabled with -y)
1362 - added custom size picture to H.263 using H.263+ (Juanjo)
1367 - added MSMPEG4 (aka DivX) compatible encoder. Changed default codec
1368 of AVI and ASF to DIV3.
1369 - added -me option to set motion estimation method
1370 (default=log). suppressed redundant -hq option.
1371 - added options -acodec and -vcodec to force a given codec (useful for
1374 - improved dct_quantize speed
1375 - factorized some motion estimation code
1380 - removing grab code from ffserver and moved it to ffmpeg. Added
1381 multistream support to ffmpeg.
1382 - added timeshifting support for live feeds (option ?date=xxx in the
1384 - added high quality image resize code with polyphase filter (need
1385 mmx/see optimization). Enable multiple image size support in ffserver.
1386 - added multi live feed support in ffserver
1387 - suppressed master feature from ffserver (it should be done with an
1388 external program which opens the .ffm url and writes it to another
1390 - added preliminary support for video stream parsing (WAV and AVI half
1391 done). Added proper support for audio/video file conversion in
1393 - added preliminary support for video file sending from ffserver
1394 - redesigning I/O subsystem: now using URL based input and output
1396 - added WAV format support
1397 - added "tty user interface" to ffmpeg to stop grabbing gracefully
1398 - added MMX/SSE optimizations to SAD (Sums of Absolutes Differences)
1399 (Juan J. Sierralta P. a.k.a. "Juanjo" <juanjo at atmlab.utfsm.cl>)
1400 - added MMX DCT from mpeg2_movie 1.5 (Juanjo)
1401 - added new motion estimation algorithms, log and phods (Juanjo)
1402 - changed directories: libav for format handling, libavcodec for
1408 - added stereo in MPEG audio encoder
1413 - added 'high quality' mode which use motion vectors. It can be used in
1414 real time at low resolution.
1415 - fixed rounding problems which caused quality problems at high
1416 bitrates and large GOP size
1419 version 0.3.2: small fixes
1425 version 0.3.1: added avi/divx support
