Answer 1

I installed OPENCV onto Windows 10 using Microsoft's VCPKG. After which, OPENCV worked fine - except it would not open videos files.

Without success, I tried many suggestions. Finally, what worked for me was very SIMPLE. I included opencv's BIN folder as a PATH in Windows Environment System Variables. That's it. Now, video files are opened and played just fine.
