Subject: V4L/DVB: gspca - sq930x: Change image format to Bayer mode Author: Jean-François Moine <moin...@free.fr> Date: Mon Jul 26 07:23:00 2010 -0300 The JPEG format did not work fine. The Bayer format offers correct VGA (640x480) resolution, but bad QQVGA (160x120). This last resolution is removed.
