/* Linux driver for Philips webcam
|
|
Decompression for chipset version 1
|
|
(C) 2004-2006 Luc Saillard (luc@saillard.org)
|
|
|
|
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.
