Hi everyone,
I know this has been discused before, but I just can't disable the
auto exposure feature on my Quickcam pro 5000. I'm coding a computer
vision program using the latest version of uvc (as of Febuary 16th).
I'm a newbie user of uvc, and I've look some sample programs, and I'm
confused about the fact that the IDs of the commands seems to change
between versions of uvc. So how do I know which one is the correct
one? Is V4L2_CID_EXPOSURE_AUTO the correct command ID for this
feature?
Here is the code I use for setting a control:
int
input_set_control (struct vdIn * device, unsigned int control, int val)
{
int fd, ret;
struct v4l2_control c;
c.id = control;
c.value = val;
ret = ioctl (fd, VIDIOC_S_CTRL, &c);
return ret;
}
It always returns -1 for V4L2_CID_EXPOSURE_AUTO.
Thanks for your help.
