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

1325 - added prototype RM demuxer
1326 - added AC3 decoding (done with libac3 by Aaron Holtzman)
1327 - added decoding codec parameter guessing (.e.g. for MPEG, because the
1328 header does not include them)
1329 - fixed header generation in MPEG-1, AVI and ASF muxer: wmplayer can now
1330 play them (only tested video)
1331 - fixed H.263 white bug

1337 - added SWF demux to extract MP3 track (not usable yet because no MP3
1339 - added fractional frame rate support
1340 - codecs are no longer searched by read_header() (should fix ffserver
1346 - BGR24 patch (initial patch by Jeroen Vreeken <pe1rxq at amsat.org>)

1350 - added B-frame handling in video core
1351 - added full MPEG-1 decoding support
1352 - added partial (frame only) MPEG-2 support
1353 - changed the FOURCC code for H.263 to "U263" to be able to see the
1354 +AVI/H.263 file with the UB Video H.263+ decoder. MPlayer works with
1355 this +codec ;) (JuanJo).
1356 - Halfpel motion estimation after MB type selection (JuanJo)
1357 - added pgm and .Y.U.V output format
1358 - suppressed 'img:' protocol. Simply use: /tmp/test%d.[pgm|Y] as input or
1360 - added pgmpipe I/O format (original patch from Martin Aumueller
1361 <lists at reserv.at>, but changed completely since we use a format
1362 instead of a protocol)
1367 - added H.263/MPEG-4/MSMPEG4 decoding support. MPEG-4 decoding support
1368 (for OpenDivX) is almost complete: 8x8 MVs and rounding are
1369 missing. MSMPEG4 support is complete.
1370 - added prototype MPEG-1 decoder. Only I- and P-frames handled yet (it
1371 can decode ffmpeg MPEGs :-)).

1378 - added file overwrite confirmation (can be disabled with -y)
1379 - added custom size picture to H.263 using H.263+ (Juanjo)
1384 - added MSMPEG4 (aka DivX) compatible encoder. Changed default codec
1385 of AVI and ASF to DIV3.
1386 - added -me option to set motion estimation method
1387 (default=log). suppressed redundant -hq option.
1388 - added options -acodec and -vcodec to force a given codec (useful for
1391 - improved dct_quantize speed
1392 - factorized some motion estimation code
1397 - removing grab code from ffserver and moved it to ffmpeg. Added
1398 multistream support to ffmpeg.
1399 - added timeshifting support for live feeds (option ?date=xxx in the
1401 - added high quality image resize code with polyphase filter (need
1402 mmx/see optimization). Enable multiple image size support in ffserver.
1403 - added multi live feed support in ffserver
1404 - suppressed master feature from ffserver (it should be done with an
1405 external program which opens the .ffm url and writes it to another
1407 - added preliminary support for video stream parsing (WAV and AVI half
1408 done). Added proper support for audio/video file conversion in
1410 - added preliminary support for video file sending from ffserver
1411 - redesigning I/O subsystem: now using URL based input and output
1413 - added WAV format support
1414 - added "tty user interface" to ffmpeg to stop grabbing gracefully
1415 - added MMX/SSE optimizations to SAD (Sums of Absolutes Differences)
1416 (Juan J. Sierralta P. a.k.a. "Juanjo" <juanjo at atmlab.utfsm.cl>)
1417 - added MMX DCT from mpeg2_movie 1.5 (Juanjo)
1418 - added new motion estimation algorithms, log and phods (Juanjo)
1419 - changed directories: libav for format handling, libavcodec for
1425 - added stereo in MPEG audio encoder
1430 - added 'high quality' mode which use motion vectors. It can be used in
1431 real time at low resolution.
1432 - fixed rounding problems which caused quality problems at high
1433 bitrates and large GOP size
1436 version 0.3.2: small fixes
1442 version 0.3.1: added avi/divx support
