Raspberry Pi Camera: I can't work with the example

I tried the “Raspberry Pi Camera” example of the Linux MBS Plugin.
I can’t get the frames from the camera. The camera is found by the Open method (returns True) but at that point there is already an “Error Code 22” (invalid argument) that I cannot understand.
Despite this, drivers, cards, busInfo, etc. are read, but no frames can be obtained.
Any suggestions?

details:
Raspberry 3b

the camera is a normal usb uvc camera
