problems running the scripts

[dtrywets]

Hey there, thanks for your great job towards Hyperion Webcam Capture.

sadly I have several issues getting the script running.
please don't mind having me running this as root, as I don't care about this installation that much ;-)

could you please help me out on this one? I'm running the scripts on a Raspberry 4 with Hyperbian and GDM3.

thanks for your help :-)

after testing around a bit I found that not using -cm fisheye lets the script run successfully but screen calibration then errors. I tried patching around the code a little bit but am not familiar with used libs and functions. :-(
