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

1278 - added MSMPEG4 (aka DivX) compatible encoder. Changed default codec
1279 of AVI and ASF to DIV3.

1281 (default=log). suppressed redundant -hq option.
1282 - added options -acodec and -vcodec to force a given codec (useful for
1285 - improved dct_quantize speed
1286 - factorized some motion estimation code
1291 - removing grab code from ffserver and moved it to ffmpeg. Added
1292 multistream support to ffmpeg.
1293 - added timeshifting support for live feeds (option ?date=xxx in the
1295 - added high quality image resize code with polyphase filter (need
1296 mmx/see optimization). Enable multiple image size support in ffserver.
1297 - added multi live feed support in ffserver
1298 - suppressed master feature from ffserver (it should be done with an
1299 external program which opens the .ffm url and writes it to another

1313 - changed directories: libav for format handling, libavcodec for
1319 - added stereo in MPEG audio encoder
1324 - added 'high quality' mode which use motion vectors. It can be used in
1325 real time at low resolution.
1326 - fixed rounding problems which caused quality problems at high
1327 bitrates and large GOP size
1330 version 0.3.2: small fixes
