The only controls that are switches are: White Balance Temperature, Auto Exposure, Auto Priority
It appears these are the same controls that are shown with uvcdynctrl -c -d /dev/video0 In particular: Brightness Contrast Saturation Hue White Balance Temperature, Auto Gamma Gain Power Line Ferquency White Balance Temperature Sharpness Backlight Compensation Exposure (Absolute) Exposure Auto Priority When I do uvcdynctrl -f -d /dev/video0 I get the following list of resolutions: 640x480 1024x768 1280x1024 320x240 160x120 1280x720 1600x1200 2048x1536 Since there are two aspect ratios, perhaps these are the two different cameras? I cant figure out how to change the resolution though. _______________________________________________ Linux-uvc-devel mailing list Linux-uvc-devel@lists.berlios.de https://lists.berlios.de/mailman/listinfo/linux-uvc-devel
