Sorry, that is of course, if there is no V4L1 compat layer still in
place.
BTW, qx5view uses a private ioctl() to change the lights on a QX5 and
not the V4L2 control.
In qx5view:
void setlight() {
#define CPIA2_IOC_SET_GPIO _IOR('v', BASE_VIDIOCPRIVATE + 17, __u32)
ioctl(dev, CPIA2_IOC_SET_GPIO, light_setting);
}
In the cpia2 driver:
/* CPIA2 extension to Video4Linux API */
case CPIA2_IOC_SET_GPIO:
retval = ioctl_set_gpio(arg, cam);
break;
Yuck.

Andy
