| 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 |
