I'll do a new libv4l release matching the bayer order change right after this mail. --------------030907010307000906060903 Content-Type: text/plain; name="gspca-sonixb-raw-mode.patch" Content-Transfer-Encoding: 7bit Content-Disposition: inline; filename="gspca-sonixb-raw-mode.patch" 2 changes in this patch: 1) Lower the hstart setting for all sensor by 1 so that we generate (compressed) BGGR data just like sn9c102 does (instead of GBRG data) 2) Add support for raw bayer output in the lowest resolutions (not enough bandwidth for higher resolutions), this should work with all sensors but to be sure only enable it for sensors where it has been tested.
