It turns out the manufacturer is ignoring requests for help. Only kind and caring people are helping... The problem remains unresolved.

@veye_xumm said in RAW-MIPI-SC132M camera working in raspberry pi 5. Cannot be configured to work with the libcamera2 and opencv libraries:

Требуется прямой вызов через v4l2 API.

Direct call via v4l2 API? What does that mean? Give an example for Python.

@alex_ai How to do this?

I got the title wrong - I meant Picamera2. I need to start working in Opencv first.

That's right. It worked with the lens. Thank you very much for your technical support.
