- version 0.9:
-
- - openal input device added
- - boxblur filter added
- - BWF muxer
- - Flash Screen Video 2 decoder
- - lavfi input device added
- - added avconv, which is almost the same for now, except
- for a few incompatible changes in the options, which will hopefully make them
- easier to use. The changes are:
- * The options placement is now strictly enforced! While in theory the
- options for ffmpeg should be given in [input options] -i INPUT [output
- options] OUTPUT order, in practice it was possible to give output options
- before the -i and it mostly worked. Except when it didn't - the behavior was
- a bit inconsistent. In avconv, it is not possible to mix input and output
- options. All non-global options are reset after an input or output filename.
- * All per-file options are now truly per-file - they apply only to the next
- input or output file and specifying different values for different files
- will now work properly (notably -ss and -t options).
- * All per-stream options are now truly per-stream - it is possible to
- specify which stream(s) should a given option apply to. See the Stream
- specifiers section in the avconv manual for details.
- * In ffmpeg some options (like -newvideo/-newaudio/...) are irregular in the
- sense that they're specified after the output filename instead of before,
- like all other options. In avconv this irregularity is removed, all options
- apply to the next input or output file.
- * -newvideo/-newaudio/-newsubtitle options were removed. Not only were they
- irregular and highly confusing, they were also redundant. In avconv the -map
- option will create new streams in the output file and map input streams to
- them. E.g. avconv -i INPUT -map 0 OUTPUT will create an output stream for
- each stream in the first input file.
- * The -map option now has slightly different and more powerful syntax:
- + Colons (':') are used to separate file index/stream type/stream index
- instead of dots. Comma (',') is used to separate the sync stream instead
- of colon.. This is done for consistency with other options.
- + It's possible to specify stream type. E.g. -map 0:a:2 creates an
- output stream from the third input audio stream.
- + Omitting the stream index now maps all the streams of the given type,
- not just the first. E.g. -map 0:s creates output streams for all the
- subtitle streams in the first input file.
- + Since -map can now match multiple streams, negative mappings were
- introduced. Negative mappings disable some streams from an already
- defined map. E.g. '-map 0 -map -0:a:1' means 'create output streams for
- all the stream in the first input file, except for the second audio
- stream'.
- * There is a new option -c (or -codec) for choosing the decoder/encoder to
- use, which makes it possible to precisely specify target stream(s) consistently with
- other options. E.g. -c:v lib264 sets the codec for all video streams, -c:a:0
- libvorbis sets the codec for the first audio stream and -c copy copies all
- the streams without reencoding. Old -vcodec/-acodec/-scodec options are now
- aliases to -c:v/a/s
- * It is now possible to precisely specify which stream should an AVOption
- apply to. E.g. -b:v:0 2M sets the bitrate for the first video stream, while
- -b:a 128k sets the bitrate for all audio streams. Note that the old -ab 128k
- syntax is deprecated and will stop working soon.
- * -map_chapters now takes only an input file index and applies to the next
- output file. This is consistent with how all the other options work.
- * -map_metadata now takes only an input metadata specifier and applies to
- the next output file. Output metadata specifier is now part of the option
- name, similarly to the AVOptions/map/codec feature above.
- * -metadata can now be used to set metadata on streams and chapters, e.g.
- -metadata:s:1 language=eng sets the language of the first stream to 'eng'.
- This made -vlang/-alang/-slang options redundant, so they were removed.
- * -qscale option now uses stream specifiers and applies to all streams, not
- just video. I.e. plain -qscale number would now apply to all streams. To get
- the old behavior, use -qscale:v. Also there is now a shortcut -q for -qscale
- and -aq is now an alias for -q:a.
- * -vbsf/-absf/-sbsf options were removed and replaced by a -bsf option which
- uses stream specifiers. Use -bsf:v/a/s instead of the old options.
- * -itsscale option now uses stream specifiers, so its argument is only the
- scale parameter.
- * -intra option was removed, use -g 0 for the same effect.
- * -psnr option was removed, use -flags +psnr for the same effect.
- * -vf option is now an alias to the new -filter option, which uses stream specifiers.
- * -vframes/-aframes/-dframes options are now aliases to the new -frames option.
- * -vtag/-atag/-stag options are now aliases to the new -tag option.
