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

686 uses stream specifiers. Use -bsf:v/a/s instead of the old options.
687 * -itsscale option now uses stream specifiers, so its argument is only the
689 * -intra option was removed, use -g 0 for the same effect.
690 * -psnr option was removed, use -flags +psnr for the same effect.
691 * -vf option is now an alias to the new -filter option, which uses stream specifiers.
692 * -vframes/-aframes/-dframes options are now aliases to the new -frames option.

1331 - added prototype RM demuxer
1332 - added AC3 decoding (done with libac3 by Aaron Holtzman)
1333 - added decoding codec parameter guessing (.e.g. for MPEG, because the
1334 header does not include them)
1335 - fixed header generation in MPEG-1, AVI and ASF muxer: wmplayer can now
1336 play them (only tested video)
1337 - fixed H.263 white bug

1343 - added SWF demux to extract MP3 track (not usable yet because no MP3
1345 - added fractional frame rate support
1346 - codecs are no longer searched by read_header() (should fix ffserver
1352 - BGR24 patch (initial patch by Jeroen Vreeken <pe1rxq at amsat.org>)

1356 - added B-frame handling in video core
1357 - added full MPEG-1 decoding support
1358 - added partial (frame only) MPEG-2 support
1359 - changed the FOURCC code for H.263 to "U263" to be able to see the
1360 +AVI/H.263 file with the UB Video H.263+ decoder. MPlayer works with
1361 this +codec ;) (JuanJo).
1362 - Halfpel motion estimation after MB type selection (JuanJo)
1363 - added pgm and .Y.U.V output format
1364 - suppressed 'img:' protocol. Simply use: /tmp/test%d.[pgm|Y] as input or
1366 - added pgmpipe I/O format (original patch from Martin Aumueller
1367 <lists at reserv.at>, but changed completely since we use a format
1368 instead of a protocol)
1373 - added H.263/MPEG-4/MSMPEG4 decoding support. MPEG-4 decoding support
1374 (for OpenDivX) is almost complete: 8x8 MVs and rounding are
1375 missing. MSMPEG4 support is complete.
1376 - added prototype MPEG-1 decoder. Only I- and P-frames handled yet (it
1377 can decode ffmpeg MPEGs :-)).

1382 and image sizes non-multiple of 16
1383 - added support for AC prediction (decoding only)
1384 - added file overwrite confirmation (can be disabled with -y)
1385 - added custom size picture to H.263 using H.263+ (Juanjo)
1390 - added MSMPEG4 (aka DivX) compatible encoder. Changed default codec
1391 of AVI and ASF to DIV3.
1392 - added -me option to set motion estimation method
1393 (default=log). suppressed redundant -hq option.
1394 - added options -acodec and -vcodec to force a given codec (useful for
1397 - improved dct_quantize speed
1398 - factorized some motion estimation code
1403 - removing grab code from ffserver and moved it to ffmpeg. Added
1404 multistream support to ffmpeg.
1405 - added timeshifting support for live feeds (option ?date=xxx in the
1407 - added high quality image resize code with polyphase filter (need
1408 mmx/see optimization). Enable multiple image size support in ffserver.
1409 - added multi live feed support in ffserver
1410 - suppressed master feature from ffserver (it should be done with an
1411 external program which opens the .ffm url and writes it to another
1413 - added preliminary support for video stream parsing (WAV and AVI half
1414 done). Added proper support for audio/video file conversion in
1416 - added preliminary support for video file sending from ffserver
1417 - redesigning I/O subsystem: now using URL based input and output
1419 - added WAV format support
1420 - added "tty user interface" to ffmpeg to stop grabbing gracefully
1421 - added MMX/SSE optimizations to SAD (Sums of Absolutes Differences)
1422 (Juan J. Sierralta P. a.k.a. "Juanjo" <juanjo at atmlab.utfsm.cl>)

1436 - added 'high quality' mode which use motion vectors. It can be used in
1437 real time at low resolution.
1438 - fixed rounding problems which caused quality problems at high
1439 bitrates and large GOP size
1442 version 0.3.2: small fixes
