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

1281 - added CPU autodetection
1282 - added generic title/author/copyright/comment string handling (ASF and RM
1284 - added SWF demux to extract MP3 track (not usable yet because no MP3
1286 - added fractional frame rate support
1287 - codecs are no longer searched by read_header() (should fix ffserver
1293 - BGR24 patch (initial patch by Jeroen Vreeken <pe1rxq at amsat.org>)
1294 - fixed raw yuv output
1295 - added motion rounding support in MPEG-4
1296 - fixed motion bug rounding in MSMPEG4
1297 - added B-frame handling in video core
1298 - added full MPEG-1 decoding support
1299 - added partial (frame only) MPEG-2 support
1300 - changed the FOURCC code for H.263 to "U263" to be able to see the
1301 +AVI/H.263 file with the UB Video H.263+ decoder. MPlayer works with
1302 this +codec ;) (JuanJo).
1303 - Halfpel motion estimation after MB type selection (JuanJo)
1304 - added pgm and .Y.U.V output format
1305 - suppressed 'img:' protocol. Simply use: /tmp/test%d.[pgm|Y] as input or
1307 - added pgmpipe I/O format (original patch from Martin Aumueller
1308 <lists at reserv.at>, but changed completely since we use a format
1309 instead of a protocol)
1314 - added H.263/MPEG-4/MSMPEG4 decoding support. MPEG-4 decoding support
1315 (for OpenDivX) is almost complete: 8x8 MVs and rounding are
1316 missing. MSMPEG4 support is complete.
1317 - added prototype MPEG-1 decoder. Only I- and P-frames handled yet (it
1318 can decode ffmpeg MPEGs :-)).
1319 - added libavcodec API documentation (see apiexample.c).
1320 - fixed image polyphase bug (the bottom of some images could be
1322 - added support for non clipped motion vectors (decoding only)
1323 and image sizes non-multiple of 16
1324 - added support for AC prediction (decoding only)
1325 - added file overwrite confirmation (can be disabled with -y)
1326 - added custom size picture to H.263 using H.263+ (Juanjo)
1331 - added MSMPEG4 (aka DivX) compatible encoder. Changed default codec
1332 of AVI and ASF to DIV3.
1333 - added -me option to set motion estimation method
1334 (default=log). suppressed redundant -hq option.
1335 - added options -acodec and -vcodec to force a given codec (useful for
1338 - improved dct_quantize speed
1339 - factorized some motion estimation code
1344 - removing grab code from ffserver and moved it to ffmpeg. Added
1345 multistream support to ffmpeg.
1346 - added timeshifting support for live feeds (option ?date=xxx in the
1348 - added high quality image resize code with polyphase filter (need
1349 mmx/see optimization). Enable multiple image size support in ffserver.
1350 - added multi live feed support in ffserver
1351 - suppressed master feature from ffserver (it should be done with an
1352 external program which opens the .ffm url and writes it to another
1354 - added preliminary support for video stream parsing (WAV and AVI half
1355 done). Added proper support for audio/video file conversion in
1357 - added preliminary support for video file sending from ffserver
1358 - redesigning I/O subsystem: now using URL based input and output
1360 - added WAV format support
1361 - added "tty user interface" to ffmpeg to stop grabbing gracefully
1362 - added MMX/SSE optimizations to SAD (Sums of Absolutes Differences)
1363 (Juan J. Sierralta P. a.k.a. "Juanjo" <juanjo at atmlab.utfsm.cl>)
1364 - added MMX DCT from mpeg2_movie 1.5 (Juanjo)
1365 - added new motion estimation algorithms, log and phods (Juanjo)
1366 - changed directories: libav for format handling, libavcodec for
1372 - added stereo in MPEG audio encoder
1377 - added 'high quality' mode which use motion vectors. It can be used in
1378 real time at low resolution.
1379 - fixed rounding problems which caused quality problems at high
1380 bitrates and large GOP size
1383 version 0.3.2: small fixes
1389 version 0.3.1: added avi/divx support
1392 - added MPEG-4 codec compatible with OpenDivX. It is based on the H.263 codec
1393 - added sound for flash format (not tested)
1396 version 0.3: initial public release
