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

1272 - added custom size picture to H.263 using H.263+ (Juanjo)
1277 - added MSMPEG4 (aka DivX) compatible encoder. Changed default codec
1278 of AVI and ASF to DIV3.
1279 - added -me option to set motion estimation method
1280 (default=log). suppressed redundant -hq option.
1281 - added options -acodec and -vcodec to force a given codec (useful for
1284 - improved dct_quantize speed
1285 - factorized some motion estimation code
1290 - removing grab code from ffserver and moved it to ffmpeg. Added
1291 multistream support to ffmpeg.
1292 - added timeshifting support for live feeds (option ?date=xxx in the
1294 - added high quality image resize code with polyphase filter (need
1295 mmx/see optimization). Enable multiple image size support in ffserver.
1296 - added multi live feed support in ffserver
1297 - suppressed master feature from ffserver (it should be done with an
1298 external program which opens the .ffm url and writes it to another

1312 - changed directories: libav for format handling, libavcodec for
1318 - added stereo in MPEG audio encoder
1323 - added 'high quality' mode which use motion vectors. It can be used in
1324 real time at low resolution.
1325 - fixed rounding problems which caused quality problems at high
1326 bitrates and large GOP size
1329 version 0.3.2: small fixes
1335 version 0.3.1: added avi/divx support
