656 - lavfi input device added
657 - added avconv, which is almost the same for now, except
658 for a few incompatible changes in the options, which will hopefully make them
659 easier to use. The changes are:
660 * The options placement is now strictly enforced! While in theory the
661 options for ffmpeg should be given in [input options] -i INPUT [output
662 options] OUTPUT order, in practice it was possible to give output options
663 before the -i and it mostly worked. Except when it didn't - the behavior was
664 a bit inconsistent. In avconv, it is not possible to mix input and output
665 options. All non-global options are reset after an input or output filename.
666 * All per-file options are now truly per-file - they apply only to the next
667 input or output file and specifying different values for different files
668 will now work properly (notably -ss and -t options).
669 * All per-stream options are now truly per-stream - it is possible to
670 specify which stream(s) should a given option apply to. See the Stream
671 specifiers section in the avconv manual for details.
672 * In ffmpeg some options (like -newvideo/-newaudio/...) are irregular in the
673 sense that they're specified after the output filename instead of before,
674 like all other options. In avconv this irregularity is removed, all options
675 apply to the next input or output file.
676 * -newvideo/-newaudio/-newsubtitle options were removed. Not only were they
677 irregular and highly confusing, they were also redundant. In avconv the -map
678 option will create new streams in the output file and map input streams to
679 them. E.g. avconv -i INPUT -map 0 OUTPUT will create an output stream for
680 each stream in the first input file.
681 * The -map option now has slightly different and more powerful syntax:
682 + Colons (':') are used to separate file index/stream type/stream index
683 instead of dots. Comma (',') is used to separate the sync stream instead
684 of colon.. This is done for consistency with other options.
685 + It's possible to specify stream type. E.g. -map 0:a:2 creates an
686 output stream from the third input audio stream.
687 + Omitting the stream index now maps all the streams of the given type,
688 not just the first. E.g. -map 0:s creates output streams for all the
689 subtitle streams in the first input file.
690 + Since -map can now match multiple streams, negative mappings were
691 introduced. Negative mappings disable some streams from an already
692 defined map. E.g. '-map 0 -map -0:a:1' means 'create output streams for
693 all the stream in the first input file, except for the second audio
695 * There is a new option -c (or -codec) for choosing the decoder/encoder to
696 use, which makes it possible to precisely specify target stream(s) consistently with
697 other options. E.g. -c:v lib264 sets the codec for all video streams, -c:a:0
698 libvorbis sets the codec for the first audio stream and -c copy copies all
699 the streams without reencoding. Old -vcodec/-acodec/-scodec options are now
701 * It is now possible to precisely specify which stream should an AVOption
702 apply to. E.g. -b:v:0 2M sets the bitrate for the first video stream, while
703 -b:a 128k sets the bitrate for all audio streams. Note that the old -ab 128k
704 syntax is deprecated and will stop working soon.
705 * -map_chapters now takes only an input file index and applies to the next
706 output file. This is consistent with how all the other options work.
707 * -map_metadata now takes only an input metadata specifier and applies to
708 the next output file. Output metadata specifier is now part of the option
709 name, similarly to the AVOptions/map/codec feature above.
710 * -metadata can now be used to set metadata on streams and chapters, e.g.
711 -metadata:s:1 language=eng sets the language of the first stream to 'eng'.
712 This made -vlang/-alang/-slang options redundant, so they were removed.
713 * -qscale option now uses stream specifiers and applies to all streams, not
714 just video. I.e. plain -qscale number would now apply to all streams. To get
715 the old behavior, use -qscale:v. Also there is now a shortcut -q for -qscale
716 and -aq is now an alias for -q:a.
717 * -vbsf/-absf/-sbsf options were removed and replaced by a -bsf option which
718 uses stream specifiers. Use -bsf:v/a/s instead of the old options.
719 * -itsscale option now uses stream specifiers, so its argument is only the
721 * -intra option was removed, use -g 0 for the same effect.
722 * -psnr option was removed, use -flags +psnr for the same effect.
723 * -vf option is now an alias to the new -filter option, which uses stream specifiers.
724 * -vframes/-aframes/-dframes options are now aliases to the new -frames option.
725 * -vtag/-atag/-stag options are now aliases to the new -tag option.
