rpiCameraGain, rpiCameraEV and rpiCameraShutter not working on Arducam IMX519

Question

I've followed the instructions here to get the Arducam IMX519 working in MediaMTX, however, the picture is rather dark.

I'm used to setting one of the following in mediamtx.yaml but with the Arducam, that doesn't seem to change anything: rpiCameraGain, rpiCameraEV and rpiCameraShutter.

Why is that and is there a way to make the picture more bright?

Thanks,
Sam

In a second test, rpiCameraEV seems to have an effect. rpiCameraGain and rpiCameraShutter don't.

I guess those are chip related.
