Opening camera on 64 bit OS

I’m trying to open the camera on 64 bit OS, but not succeeding.
I am aware that the MMAL drivers are not available in 64 bit OS, but still not having any progress with v4l2 either.

I am specifically attempting this on the CM4, but the results are the same on the Pi4.

Very little information on the forums regarding this, has anyone had any success?

Hello @mckelvaney Thanks for your message and welcome to the balena forums!

What project are you trying to run on the CM4? is it balenaCam? What carrier board are you using? I would like to reproduce myself!

Thanks
