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