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

1273 instead of a protocol)
1278 - added H.263/MPEG-4/MSMPEG4 decoding support. MPEG-4 decoding support
1279 (for OpenDivX) is almost complete: 8x8 MVs and rounding are
1280 missing. MSMPEG4 support is complete.
1281 - added prototype MPEG-1 decoder. Only I- and P-frames handled yet (it
1282 can decode ffmpeg MPEGs :-)).
1283 - added libavcodec API documentation (see apiexample.c).
1284 - fixed image polyphase bug (the bottom of some images could be
1286 - added support for non clipped motion vectors (decoding only)
1287 and image sizes non-multiple of 16
1288 - added support for AC prediction (decoding only)
1289 - added file overwrite confirmation (can be disabled with -y)
1290 - added custom size picture to H.263 using H.263+ (Juanjo)
1295 - added MSMPEG4 (aka DivX) compatible encoder. Changed default codec
1296 of AVI and ASF to DIV3.
1297 - added -me option to set motion estimation method
1298 (default=log). suppressed redundant -hq option.
1299 - added options -acodec and -vcodec to force a given codec (useful for
1302 - improved dct_quantize speed
1303 - factorized some motion estimation code
1308 - removing grab code from ffserver and moved it to ffmpeg. Added
1309 multistream support to ffmpeg.
1310 - added timeshifting support for live feeds (option ?date=xxx in the
1312 - added high quality image resize code with polyphase filter (need
1313 mmx/see optimization). Enable multiple image size support in ffserver.
1314 - added multi live feed support in ffserver
1315 - suppressed master feature from ffserver (it should be done with an
1316 external program which opens the .ffm url and writes it to another
1318 - added preliminary support for video stream parsing (WAV and AVI half
1319 done). Added proper support for audio/video file conversion in
1321 - added preliminary support for video file sending from ffserver
1322 - redesigning I/O subsystem: now using URL based input and output
1324 - added WAV format support
1325 - added "tty user interface" to ffmpeg to stop grabbing gracefully
1326 - added MMX/SSE optimizations to SAD (Sums of Absolutes Differences)
1327 (Juan J. Sierralta P. a.k.a. "Juanjo" <juanjo at atmlab.utfsm.cl>)
1328 - added MMX DCT from mpeg2_movie 1.5 (Juanjo)
1329 - added new motion estimation algorithms, log and phods (Juanjo)
1330 - changed directories: libav for format handling, libavcodec for
1336 - added stereo in MPEG audio encoder
1341 - added 'high quality' mode which use motion vectors. It can be used in
1342 real time at low resolution.
1343 - fixed rounding problems which caused quality problems at high
1344 bitrates and large GOP size
1347 version 0.3.2: small fixes
1353 version 0.3.1: added avi/divx support
1356 - added MPEG-4 codec compatible with OpenDivX. It is based on the H.263 codec
1357 - added sound for flash format (not tested)
1360 version 0.3: initial public release
