This plugin wraps the SGI Audiofile
|
||
|
|
(http://oss.sgi.com/projects/audiofile/) library into a src and sink
|
||
|
|
element.
|
||
|
|
|
||
|
|
You can read from and write to the supported formats (WAVE, AIFF, AIFFC,
|
||
|
|
NEXTSND).
|
||
|
|
|
||
|
|
What is supported :
|
||
|
|
* all the file formats
|
||
|
|
* integer sample data, both 2's complement and unsigned
|
||
|
|
* 8 or 16 bit width & depth (haven't tested others)
|
||
|
|
* sample rate
|
||
|
|
* some sort of endianness control
|
||
|
|
|
||
|
|
What isn't supported yet :
|
||
|
|
* float data
|
||
|
|
|
||
|
|
What you can do :
|
||
|
|
* src element only accepts location argument
|
||
|
|
* sink element accepts location, endianness and type
|
||
|
|
- location : file on the system to output
|
||
|
|
- endianness : at this time endianness is still a bit shady
|
||
|
|
you can either set 1234 or 4321;
|
||
|
|
setting it to 4321 will byteswap the buffer data
|
||
|
|
you might want to keep it at 1234 for now
|
||
|
|
- type : one of the file types
|
||
|
|
|
||
|
|
Use gstreamer-inspect on afsink and afsrc to see all of the supported
|
||
|
|
options.
|
||
|
|
|
||
|
|
Examples :
|
||
|
|
|
||
|
|
* tools/gstreamer-launch afsrc location=/opt/media/wav/dark-480-16-m.wav ! afsink type=2 location=/opt/media/wav/dark-480-16-m.aiff
|
||
|
|
|
||
|
|
Future plans :
|
||
|
|
|
||
|
|
* add float support
|
||
|
|
* wrap up afsink and afsrc with pipe and fork to act like data convertors,
|
||
|
|
allowing arbitrary choice of sink and src element
