@achrafba

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.

Thank you Dion.

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