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