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

1278 - added CPU autodetection
1279 - added generic title/author/copyright/comment string handling (ASF and RM
1281 - added SWF demux to extract MP3 track (not usable yet because no MP3
1283 - added fractional frame rate support
1284 - codecs are no longer searched by read_header() (should fix ffserver
1290 - BGR24 patch (initial patch by Jeroen Vreeken <pe1rxq at amsat.org>)
1291 - fixed raw yuv output
1292 - added motion rounding support in MPEG-4
1293 - fixed motion bug rounding in MSMPEG4
1294 - added B-frame handling in video core
1295 - added full MPEG-1 decoding support
1296 - added partial (frame only) MPEG-2 support
1297 - changed the FOURCC code for H.263 to "U263" to be able to see the
1298 +AVI/H.263 file with the UB Video H.263+ decoder. MPlayer works with
1299 this +codec ;) (JuanJo).
1300 - Halfpel motion estimation after MB type selection (JuanJo)
1301 - added pgm and .Y.U.V output format
1302 - suppressed 'img:' protocol. Simply use: /tmp/test%d.[pgm|Y] as input or
1304 - added pgmpipe I/O format (original patch from Martin Aumueller
1305 <lists at reserv.at>, but changed completely since we use a format
1306 instead of a protocol)
1311 - added H.263/MPEG-4/MSMPEG4 decoding support. MPEG-4 decoding support
1312 (for OpenDivX) is almost complete: 8x8 MVs and rounding are
1313 missing. MSMPEG4 support is complete.
1314 - added prototype MPEG-1 decoder. Only I- and P-frames handled yet (it
1315 can decode ffmpeg MPEGs :-)).
1316 - added libavcodec API documentation (see apiexample.c).
1317 - fixed image polyphase bug (the bottom of some images could be
1319 - added support for non clipped motion vectors (decoding only)
1320 and image sizes non-multiple of 16
1321 - added support for AC prediction (decoding only)
1322 - added file overwrite confirmation (can be disabled with -y)
1323 - added custom size picture to H.263 using H.263+ (Juanjo)
1328 - added MSMPEG4 (aka DivX) compatible encoder. Changed default codec
1329 of AVI and ASF to DIV3.
1330 - added -me option to set motion estimation method
1331 (default=log). suppressed redundant -hq option.
1332 - added options -acodec and -vcodec to force a given codec (useful for
1335 - improved dct_quantize speed
1336 - factorized some motion estimation code
1341 - removing grab code from ffserver and moved it to ffmpeg. Added
1342 multistream support to ffmpeg.
1343 - added timeshifting support for live feeds (option ?date=xxx in the
1345 - added high quality image resize code with polyphase filter (need
1346 mmx/see optimization). Enable multiple image size support in ffserver.
1347 - added multi live feed support in ffserver
1348 - suppressed master feature from ffserver (it should be done with an
1349 external program which opens the .ffm url and writes it to another
1351 - added preliminary support for video stream parsing (WAV and AVI half
1352 done). Added proper support for audio/video file conversion in
1354 - added preliminary support for video file sending from ffserver
1355 - redesigning I/O subsystem: now using URL based input and output
1357 - added WAV format support
1358 - added "tty user interface" to ffmpeg to stop grabbing gracefully
1359 - added MMX/SSE optimizations to SAD (Sums of Absolutes Differences)
1360 (Juan J. Sierralta P. a.k.a. "Juanjo" <juanjo at atmlab.utfsm.cl>)
1361 - added MMX DCT from mpeg2_movie 1.5 (Juanjo)
1362 - added new motion estimation algorithms, log and phods (Juanjo)
1363 - changed directories: libav for format handling, libavcodec for
1369 - added stereo in MPEG audio encoder
1374 - added 'high quality' mode which use motion vectors. It can be used in
1375 real time at low resolution.
1376 - fixed rounding problems which caused quality problems at high
1377 bitrates and large GOP size
1380 version 0.3.2: small fixes
1386 version 0.3.1: added avi/divx support
1389 - added MPEG-4 codec compatible with OpenDivX. It is based on the H.263 codec
1390 - added sound for flash format (not tested)
1393 version 0.3: initial public release
