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