Subject: PATCH: gspca, spca561: fix low res modes
Date: Thu, 03 Jul 2008 12:41:25 +0200 [thread overview]
Message-ID: <486CACD5.1020307@hhs.nl> (raw)
[-- Attachment #1: Type: text/plain, Size: 278 bytes --]
Hi All,
The low (half) res modes of the spca561 are not spca561 compressed, but are
raw bayer, this patches fixes this and adds a PIX_FMT define for the GBRG
bayer format used by the spca561 in low res mode.

Regards,
Hans
