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

1282 - added motion rounding support in MPEG-4
1283 - fixed motion bug rounding in MSMPEG4
1284 - added B-frame handling in video core
1285 - added full MPEG-1 decoding support
1286 - added partial (frame only) MPEG-2 support
1287 - changed the FOURCC code for H.263 to "U263" to be able to see the
1288 +AVI/H.263 file with the UB Video H.263+ decoder. MPlayer works with
1289 this +codec ;) (JuanJo).
1290 - Halfpel motion estimation after MB type selection (JuanJo)
1291 - added pgm and .Y.U.V output format
1292 - suppressed 'img:' protocol. Simply use: /tmp/test%d.[pgm|Y] as input or
1294 - added pgmpipe I/O format (original patch from Martin Aumueller
1295 <lists at reserv.at>, but changed completely since we use a format
1296 instead of a protocol)
1301 - added H.263/MPEG-4/MSMPEG4 decoding support. MPEG-4 decoding support
1302 (for OpenDivX) is almost complete: 8x8 MVs and rounding are
1303 missing. MSMPEG4 support is complete.
1304 - added prototype MPEG-1 decoder. Only I- and P-frames handled yet (it
1305 can decode ffmpeg MPEGs :-)).
1306 - added libavcodec API documentation (see apiexample.c).
1307 - fixed image polyphase bug (the bottom of some images could be
1309 - added support for non clipped motion vectors (decoding only)
1310 and image sizes non-multiple of 16
1311 - added support for AC prediction (decoding only)
1312 - added file overwrite confirmation (can be disabled with -y)
1313 - added custom size picture to H.263 using H.263+ (Juanjo)
1318 - added MSMPEG4 (aka DivX) compatible encoder. Changed default codec
1319 of AVI and ASF to DIV3.
1320 - added -me option to set motion estimation method
1321 (default=log). suppressed redundant -hq option.
1322 - added options -acodec and -vcodec to force a given codec (useful for
1325 - improved dct_quantize speed
1326 - factorized some motion estimation code
1331 - removing grab code from ffserver and moved it to ffmpeg. Added
1332 multistream support to ffmpeg.
1333 - added timeshifting support for live feeds (option ?date=xxx in the
1335 - added high quality image resize code with polyphase filter (need
1336 mmx/see optimization). Enable multiple image size support in ffserver.
1337 - added multi live feed support in ffserver
1338 - suppressed master feature from ffserver (it should be done with an
1339 external program which opens the .ffm url and writes it to another
1341 - added preliminary support for video stream parsing (WAV and AVI half
1342 done). Added proper support for audio/video file conversion in
1344 - added preliminary support for video file sending from ffserver
1345 - redesigning I/O subsystem: now using URL based input and output
1347 - added WAV format support
1348 - added "tty user interface" to ffmpeg to stop grabbing gracefully
1349 - added MMX/SSE optimizations to SAD (Sums of Absolutes Differences)
1350 (Juan J. Sierralta P. a.k.a. "Juanjo" <juanjo at atmlab.utfsm.cl>)
1351 - added MMX DCT from mpeg2_movie 1.5 (Juanjo)
1352 - added new motion estimation algorithms, log and phods (Juanjo)
1353 - changed directories: libav for format handling, libavcodec for
1359 - added stereo in MPEG audio encoder
1364 - added 'high quality' mode which use motion vectors. It can be used in
1365 real time at low resolution.
1366 - fixed rounding problems which caused quality problems at high
1367 bitrates and large GOP size
1370 version 0.3.2: small fixes
1376 version 0.3.1: added avi/divx support
1379 - added MPEG-4 codec compatible with OpenDivX. It is based on the H.263 codec
1380 - added sound for flash format (not tested)
1383 version 0.3: initial public release
