Hello,
The OV511 uses a proprietary compression algorithm which is not implemented
in linux driver because OmniVision (www.ovt.com)doesn't want to release the
specs.
This compression is working in Windows.
Perhaps you can also write Omnivision to release their algorithm
(OmniCE) to the linux community.
Francois.
