version next:
|
|
|
|
- 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:
|
|
* -newvideo/-newaudio/-newsubtitle are gone, because they were redundant and
|
|
worked in a nonstandard way. -map is sufficient to add streams to output
|
|
files.
|
|
* -map now has slightly different and more powerful syntax.
|
|
+ it's possible to specify stream type. E.g. -map 0:a:2 means 'third
|
|
audio stream'.
|
|
+ omitting the stream index now maps all the streams of the given
|
|
type, not just the first. E.g. -map 0:s maps all the subtitle streams.
|
|
+ colons (':') are used to separate file index/stream type/stream
|
|
index. Comma (',') is used to separate the sync stream. This is done
|
|
for consistency with other options.
|
|
+ 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 'map everything except
|
|
for the second audio stream'.
|
|
* -vcodec/-acodec/-scodec are replaced by -c (or -codec), which
|
|
allows to precisely specify target stream(s) consistently with other
|
|
options. E.g. '-c:v libx264' 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.
|
|
* It is now possible to precisely specify which stream should an AVOption
|
|
apply to. See the manual for detailed explanation.
|
|
* -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.
|
|
* Presets in avconv are disabled, because only libx264 used them and
|
|
presets for libx264 can now be specified using a private option
|
|
'-preset <presetname>'.
|
|
* -intra option was removed, it's equivalent to -g 0.
