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
