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

1272 instead of a protocol)
1277 - added H.263/MPEG-4/MSMPEG4 decoding support. MPEG-4 decoding support
1278 (for OpenDivX) is almost complete: 8x8 MVs and rounding are
1279 missing. MSMPEG4 support is complete.
1280 - added prototype MPEG-1 decoder. Only I- and P-frames handled yet (it
1281 can decode ffmpeg MPEGs :-)).
1282 - added libavcodec API documentation (see apiexample.c).
1283 - fixed image polyphase bug (the bottom of some images could be
1285 - added support for non clipped motion vectors (decoding only)
1286 and image sizes non-multiple of 16
1287 - added support for AC prediction (decoding only)
1288 - added file overwrite confirmation (can be disabled with -y)
1289 - added custom size picture to H.263 using H.263+ (Juanjo)
1294 - added MSMPEG4 (aka DivX) compatible encoder. Changed default codec
1295 of AVI and ASF to DIV3.
1296 - added -me option to set motion estimation method
1297 (default=log). suppressed redundant -hq option.
1298 - added options -acodec and -vcodec to force a given codec (useful for
1301 - improved dct_quantize speed
1302 - factorized some motion estimation code
1307 - removing grab code from ffserver and moved it to ffmpeg. Added
1308 multistream support to ffmpeg.
1309 - added timeshifting support for live feeds (option ?date=xxx in the
1311 - added high quality image resize code with polyphase filter (need
1312 mmx/see optimization). Enable multiple image size support in ffserver.
1313 - added multi live feed support in ffserver
1314 - suppressed master feature from ffserver (it should be done with an
1315 external program which opens the .ffm url and writes it to another
1317 - added preliminary support for video stream parsing (WAV and AVI half
1318 done). Added proper support for audio/video file conversion in
1320 - added preliminary support for video file sending from ffserver
1321 - redesigning I/O subsystem: now using URL based input and output
1323 - added WAV format support
1324 - added "tty user interface" to ffmpeg to stop grabbing gracefully
1325 - added MMX/SSE optimizations to SAD (Sums of Absolutes Differences)
1326 (Juan J. Sierralta P. a.k.a. "Juanjo" <juanjo at atmlab.utfsm.cl>)
1327 - added MMX DCT from mpeg2_movie 1.5 (Juanjo)
1328 - added new motion estimation algorithms, log and phods (Juanjo)
1329 - changed directories: libav for format handling, libavcodec for
1335 - added stereo in MPEG audio encoder
1340 - added 'high quality' mode which use motion vectors. It can be used in
1341 real time at low resolution.
1342 - fixed rounding problems which caused quality problems at high
1343 bitrates and large GOP size
1346 version 0.3.2: small fixes
1352 version 0.3.1: added avi/divx support
1355 - added MPEG-4 codec compatible with OpenDivX. It is based on the H.263 codec
1356 - added sound for flash format (not tested)
1359 version 0.3: initial public release
