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

1276 this +codec ;) (JuanJo).
1277 - Halfpel motion estimation after MB type selection (JuanJo)
1278 - added pgm and .Y.U.V output format
1279 - suppressed 'img:' protocol. Simply use: /tmp/test%d.[pgm|Y] as input or
1281 - added pgmpipe I/O format (original patch from Martin Aumueller
1282 <lists at reserv.at>, but changed completely since we use a format
1283 instead of a protocol)
1288 - added H.263/MPEG-4/MSMPEG4 decoding support. MPEG-4 decoding support
1289 (for OpenDivX) is almost complete: 8x8 MVs and rounding are
1290 missing. MSMPEG4 support is complete.
1291 - added prototype MPEG-1 decoder. Only I- and P-frames handled yet (it
1292 can decode ffmpeg MPEGs :-)).
1293 - added libavcodec API documentation (see apiexample.c).
1294 - fixed image polyphase bug (the bottom of some images could be
1296 - added support for non clipped motion vectors (decoding only)
1297 and image sizes non-multiple of 16
1298 - added support for AC prediction (decoding only)
1299 - added file overwrite confirmation (can be disabled with -y)
1300 - added custom size picture to H.263 using H.263+ (Juanjo)
1305 - added MSMPEG4 (aka DivX) compatible encoder. Changed default codec
1306 of AVI and ASF to DIV3.
1307 - added -me option to set motion estimation method
1308 (default=log). suppressed redundant -hq option.
1309 - added options -acodec and -vcodec to force a given codec (useful for
1312 - improved dct_quantize speed
1313 - factorized some motion estimation code
1318 - removing grab code from ffserver and moved it to ffmpeg. Added
1319 multistream support to ffmpeg.
1320 - added timeshifting support for live feeds (option ?date=xxx in the
1322 - added high quality image resize code with polyphase filter (need
1323 mmx/see optimization). Enable multiple image size support in ffserver.
1324 - added multi live feed support in ffserver
1325 - suppressed master feature from ffserver (it should be done with an
1326 external program which opens the .ffm url and writes it to another
1328 - added preliminary support for video stream parsing (WAV and AVI half
1329 done). Added proper support for audio/video file conversion in
1331 - added preliminary support for video file sending from ffserver
1332 - redesigning I/O subsystem: now using URL based input and output
1334 - added WAV format support
1335 - added "tty user interface" to ffmpeg to stop grabbing gracefully
1336 - added MMX/SSE optimizations to SAD (Sums of Absolutes Differences)
1337 (Juan J. Sierralta P. a.k.a. "Juanjo" <juanjo at atmlab.utfsm.cl>)
1338 - added MMX DCT from mpeg2_movie 1.5 (Juanjo)
1339 - added new motion estimation algorithms, log and phods (Juanjo)
1340 - changed directories: libav for format handling, libavcodec for
1346 - added stereo in MPEG audio encoder
1351 - added 'high quality' mode which use motion vectors. It can be used in
1352 real time at low resolution.
1353 - fixed rounding problems which caused quality problems at high
1354 bitrates and large GOP size
1357 version 0.3.2: small fixes
1363 version 0.3.1: added avi/divx support
1366 - added MPEG-4 codec compatible with OpenDivX. It is based on the H.263 codec
1367 - added sound for flash format (not tested)
1370 version 0.3: initial public release
