NOTE: this version of pwc is an unofficial (modified) release of pwc & pcwx
|
|
driver and thus may have bugs that are not present in the original version.
|
|
Please send bug reports and support requests to <luc@saillard.org>.
|
|
The decompression routines have been implemented by reverse-engineering the
|
|
Nemosoft binary pwcx module. Caveat emptor.

/* This tables contains entries for the 675/680/690 (Timon) camera, with
|
|
4 different qualities (no compression, low, medium, high).
|
|
It lists the bandwidth requirements for said mode by its alternate interface
|
|
number. An alternate of 0 means that the mode is unavailable.
|
|
|
|
There are 6 * 4 * 4 entries:
|
|
6 different resolutions subqcif, qsif, qcif, sif, cif, vga
|
|
6 framerates: 5, 10, 15, 20, 25, 30
|
|
4 compression modi: none, low, medium, high
|
|
|
|
When an uncompressed mode is not available, the next available compressed mode
|
|
will be chosen (unless the decompressor is absent). Sometimes there are only
|
|
1 or 2 compressed modes available; in that case entries are duplicated.
