820 - Flash Screen Video 2 decoder
821 - lavfi input device added
822 - added avconv, which is almost the same for now, except
823 for a few incompatible changes in the options, which will hopefully make them
824 easier to use. The changes are:
825 * The options placement is now strictly enforced! While in theory the
826 options for ffmpeg should be given in [input options] -i INPUT [output
827 options] OUTPUT order, in practice it was possible to give output options
828 before the -i and it mostly worked. Except when it didn't - the behavior was
829 a bit inconsistent. In avconv, it is not possible to mix input and output
830 options. All non-global options are reset after an input or output filename.
831 * All per-file options are now truly per-file - they apply only to the next
832 input or output file and specifying different values for different files
833 will now work properly (notably -ss and -t options).
834 * All per-stream options are now truly per-stream - it is possible to
835 specify which stream(s) should a given option apply to. See the Stream
836 specifiers section in the avconv manual for details.
837 * In ffmpeg some options (like -newvideo/-newaudio/...) are irregular in the
838 sense that they're specified after the output filename instead of before,
839 like all other options. In avconv this irregularity is removed, all options
840 apply to the next input or output file.
841 * -newvideo/-newaudio/-newsubtitle options were removed. Not only were they
842 irregular and highly confusing, they were also redundant. In avconv the -map
843 option will create new streams in the output file and map input streams to
844 them. E.g. avconv -i INPUT -map 0 OUTPUT will create an output stream for
845 each stream in the first input file.
846 * The -map option now has slightly different and more powerful syntax:
847 + Colons (':') are used to separate file index/stream type/stream index
848 instead of dots. Comma (',') is used to separate the sync stream instead
849 of colon.. This is done for consistency with other options.
850 + It's possible to specify stream type. E.g. -map 0:a:2 creates an
851 output stream from the third input audio stream.
852 + Omitting the stream index now maps all the streams of the given type,
853 not just the first. E.g. -map 0:s creates output streams for all the
854 subtitle streams in the first input file.
855 + Since -map can now match multiple streams, negative mappings were
856 introduced. Negative mappings disable some streams from an already
857 defined map. E.g. '-map 0 -map -0:a:1' means 'create output streams for
858 all the stream in the first input file, except for the second audio
860 * There is a new option -c (or -codec) for choosing the decoder/encoder to
861 use, which makes it possible to precisely specify target stream(s) consistently with
862 other options. E.g. -c:v lib264 sets the codec for all video streams, -c:a:0
863 libvorbis sets the codec for the first audio stream and -c copy copies all
864 the streams without reencoding. Old -vcodec/-acodec/-scodec options are now
866 * It is now possible to precisely specify which stream should an AVOption
867 apply to. E.g. -b:v:0 2M sets the bitrate for the first video stream, while
868 -b:a 128k sets the bitrate for all audio streams. Note that the old -ab 128k
869 syntax is deprecated and will stop working soon.
870 * -map_chapters now takes only an input file index and applies to the next
871 output file. This is consistent with how all the other options work.
872 * -map_metadata now takes only an input metadata specifier and applies to
873 the next output file. Output metadata specifier is now part of the option
874 name, similarly to the AVOptions/map/codec feature above.
875 * -metadata can now be used to set metadata on streams and chapters, e.g.
876 -metadata:s:1 language=eng sets the language of the first stream to 'eng'.
877 This made -vlang/-alang/-slang options redundant, so they were removed.
878 * -qscale option now uses stream specifiers and applies to all streams, not
879 just video. I.e. plain -qscale number would now apply to all streams. To get
880 the old behavior, use -qscale:v. Also there is now a shortcut -q for -qscale
881 and -aq is now an alias for -q:a.
882 * -vbsf/-absf/-sbsf options were removed and replaced by a -bsf option which
883 uses stream specifiers. Use -bsf:v/a/s instead of the old options.
884 * -itsscale option now uses stream specifiers, so its argument is only the
886 * -intra option was removed, use -g 0 for the same effect.
887 * -psnr option was removed, use -flags +psnr for the same effect.
888 * -vf option is now an alias to the new -filter option, which uses stream specifiers.
889 * -vframes/-aframes/-dframes options are now aliases to the new -frames option.
890 * -vtag/-atag/-stag options are now aliases to the new -tag option.
