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 allows 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.

|
|
done). Added proper support for audio/video file conversion in
