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

1276 (for OpenDivX) is almost complete: 8x8 MVs and rounding are
1277 missing. MSMPEG4 support is complete.
1278 - added prototype MPEG-1 decoder. Only I- and P-frames handled yet (it
1279 can decode ffmpeg MPEGs :-)).
1280 - added libavcodec API documentation (see apiexample.c).
1281 - fixed image polyphase bug (the bottom of some images could be
1283 - added support for non clipped motion vectors (decoding only)
1284 and image sizes non-multiple of 16
1285 - added support for AC prediction (decoding only)
1286 - added file overwrite confirmation (can be disabled with -y)
1287 - added custom size picture to H.263 using H.263+ (Juanjo)
1292 - added MSMPEG4 (aka DivX) compatible encoder. Changed default codec
1293 of AVI and ASF to DIV3.
1294 - added -me option to set motion estimation method
1295 (default=log). suppressed redundant -hq option.
1296 - added options -acodec and -vcodec to force a given codec (useful for
1299 - improved dct_quantize speed
1300 - factorized some motion estimation code
1305 - removing grab code from ffserver and moved it to ffmpeg. Added
1306 multistream support to ffmpeg.
1307 - added timeshifting support for live feeds (option ?date=xxx in the
1309 - added high quality image resize code with polyphase filter (need
1310 mmx/see optimization). Enable multiple image size support in ffserver.
1311 - added multi live feed support in ffserver
1312 - suppressed master feature from ffserver (it should be done with an
1313 external program which opens the .ffm url and writes it to another
1315 - added preliminary support for video stream parsing (WAV and AVI half
1316 done). Added proper support for audio/video file conversion in
1318 - added preliminary support for video file sending from ffserver
1319 - redesigning I/O subsystem: now using URL based input and output
1321 - added WAV format support
1322 - added "tty user interface" to ffmpeg to stop grabbing gracefully
1323 - added MMX/SSE optimizations to SAD (Sums of Absolutes Differences)
1324 (Juan J. Sierralta P. a.k.a. "Juanjo" <juanjo at atmlab.utfsm.cl>)
1325 - added MMX DCT from mpeg2_movie 1.5 (Juanjo)
1326 - added new motion estimation algorithms, log and phods (Juanjo)
1327 - changed directories: libav for format handling, libavcodec for
1333 - added stereo in MPEG audio encoder
1338 - added 'high quality' mode which use motion vectors. It can be used in
1339 real time at low resolution.
1340 - fixed rounding problems which caused quality problems at high
1341 bitrates and large GOP size
1344 version 0.3.2: small fixes
1350 version 0.3.1: added avi/divx support
1353 - added MPEG-4 codec compatible with OpenDivX. It is based on the H.263 codec
1354 - added sound for flash format (not tested)
1357 version 0.3: initial public release
