I have some virtual cameras on my system that have no available formats,
and this leads to e.g.:
>>> x = CameraDevice.getAvailableDevices()
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "...\psychopy\hardware\camera\__init__.py", line 614, in getAvailableDevices
minFrameRate = max(28, min([cam.frameRate for cam in allCams]))
ValueError: min() arg is an empty sequence
As far as I can tell, this is the only place where non-emptiness is assumed?

Tested vs. 2026.1.1 on Windows 11. This lets the app device manager successfully list the built-in webcam.
