IDK what to make of this. the “Unknown C++ exception” being unknown is a problem. It could be a complex issue involving the compilation/linking of the program or the finding of DLLs.
or it could be that the video file isn’t where it is expected to be.
you might wanna check the values of os.path.exists(video_path) as well as os.getcwd()
if that’s not it, I don’t know how to help.
