I have a Logitech Sphere webcam on an OpenWRT machine.
I am using such webcams for my surveillance system, and it would be good to
use the pan/tilt/focus control. (Currently it have been set using Windows.)
For the first try the VIDIOC_QUERYCTRL ioctl call is failed for all extended
features (like V4L2_CID_PAN_ABSOLUTE).
Is it supported anyway? Is it necessary to use some additional tool or
Thanx in advance
