405 - Flash Screen Video 2 decoder
406 - lavfi input device added
407 - added avconv, which is almost the same for now, except
408 for a few incompatible changes in the options, which will hopefully make them
409 easier to use. The changes are:
410 * The options placement is now strictly enforced! While in theory the
411 options for ffmpeg should be given in [input options] -i INPUT [output
412 options] OUTPUT order, in practice it was possible to give output options
413 before the -i and it mostly worked. Except when it didn't - the behavior was
414 a bit inconsistent. In avconv, it is not possible to mix input and output
415 options. All non-global options are reset after an input or output filename.
416 * All per-file options are now truly per-file - they apply only to the next
417 input or output file and specifying different values for different files
418 will now work properly (notably -ss and -t options).
419 * All per-stream options are now truly per-stream - it is possible to
420 specify which stream(s) should a given option apply to. See the Stream
421 specifiers section in the avconv manual for details.
422 * In ffmpeg some options (like -newvideo/-newaudio/...) are irregular in the
423 sense that they're specified after the output filename instead of before,
424 like all other options. In avconv this irregularity is removed, all options
425 apply to the next input or output file.
426 * -newvideo/-newaudio/-newsubtitle options were removed. Not only were they
427 irregular and highly confusing, they were also redundant. In avconv the -map
428 option will create new streams in the output file and map input streams to
429 them. E.g. avconv -i INPUT -map 0 OUTPUT will create an output stream for
430 each stream in the first input file.
431 * The -map option now has slightly different and more powerful syntax:
432 + Colons (':') are used to separate file index/stream type/stream index
433 instead of dots. Comma (',') is used to separate the sync stream instead
434 of colon.. This is done for consistency with other options.
435 + It's possible to specify stream type. E.g. -map 0:a:2 creates an
436 output stream from the third input audio stream.
437 + Omitting the stream index now maps all the streams of the given type,
438 not just the first. E.g. -map 0:s creates output streams for all the
439 subtitle streams in the first input file.
440 + Since -map can now match multiple streams, negative mappings were
441 introduced. Negative mappings disable some streams from an already
442 defined map. E.g. '-map 0 -map -0:a:1' means 'create output streams for
443 all the stream in the first input file, except for the second audio
445 * There is a new option -c (or -codec) for choosing the decoder/encoder to
446 use, which allows to precisely specify target stream(s) consistently with
447 other options. E.g. -c:v lib264 sets the codec for all video streams, -c:a:0
448 libvorbis sets the codec for the first audio stream and -c copy copies all
449 the streams without reencoding. Old -vcodec/-acodec/-scodec options are now
451 * It is now possible to precisely specify which stream should an AVOption
452 apply to. E.g. -b:v:0 2M sets the bitrate for the first video stream, while
453 -b:a 128k sets the bitrate for all audio streams. Note that the old -ab 128k
454 syntax is deprecated and will stop working soon.
455 * -map_chapters now takes only an input file index and applies to the next
456 output file. This is consistent with how all the other options work.
457 * -map_metadata now takes only an input metadata specifier and applies to
458 the next output file. Output metadata specifier is now part of the option
459 name, similarly to the AVOptions/map/codec feature above.
460 * -metadata can now be used to set metadata on streams and chapters, e.g.
461 -metadata:s:1 language=eng sets the language of the first stream to 'eng'.
462 This made -vlang/-alang/-slang options redundant, so they were removed.
463 * -qscale option now uses stream specifiers and applies to all streams, not
464 just video. I.e. plain -qscale number would now apply to all streams. To get
465 the old behavior, use -qscale:v. Also there is now a shortcut -q for -qscale
466 and -aq is now an alias for -q:a.
467 * -vbsf/-absf/-sbsf options were removed and replaced by a -bsf option which
468 uses stream specifiers. Use -bsf:v/a/s instead of the old options.
469 * -itsscale option now uses stream specifiers, so its argument is only the
471 * -intra option was removed, use -g 0 for the same effect.
472 * -psnr option was removed, use -flags +psnr for the same effect.
473 * -vf option is now an alias to the new -filter option, which uses stream specifiers.
474 * -vframes/-aframes/-dframes options are now aliases to the new -frames option.
475 * -vtag/-atag/-stag options are now aliases to the new -tag option.
