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

27 | /* This tables contains entries for the 675/680/690 (Timon) camera, with | ||
28 | 4 different qualities (no compression, low, medium, high). | ||
29 | It lists the bandwidth requirements for said mode by its alternate interface | ||
30 | number. An alternate of 0 means that the mode is unavailable. | ||
31 | |||
32 | There are 6 * 4 * 4 entries: | ||
33 | 6 different resolutions subqcif, qsif, qcif, sif, cif, vga | ||
34 | 6 framerates: 5, 10, 15, 20, 25, 30 | ||
35 | 4 compression modi: none, low, medium, high | ||
36 | |||
37 | When an uncompressed mode is not available, the next available compressed mode | ||
38 | will be chosen (unless the decompressor is absent). Sometimes there are only | ||
39 | 1 or 2 compressed modes available; in that case entries are duplicated. | ||
