  5. Problems you were having?
    v4l2-ctl doens show real fps
    libcamera doesn’t detect camera

    Why camera is not detected by libcamera?
    How to select mode (Y8 vs Y10)

Is the support team busy?


Sorry, obisp can only use arducamstill. you can’t use libcamera.

Sorry again, because many times I have some other things going on that cause me to forget to reply to some users. If I forget to reply please remind me again.


Thank you Edward.
How about the wrong FPS that I am getting (Interval: Discrete 0.000s (4294967294.000 fps)
How I can select between GREY, Y10P, Y10? In the list of controls, sensor mode is not available.

I think the link below will be a little helpful for you.

Thank you Dion.

Do you mean “Interval: Discrete 0.000s (4294967294.000 fps)” is not an error?
