Been doing that. Taking to a friend of mine and I believe its something that's related to macOS. I'll try testing with Linux.

Then I'll take it that the tutorial is broken as this is what their code returns.

It still gives a similar error, but it is now complaining about an array being out of bounds.

Hi I was trying to use this tutorial to do some video manipulation with OpenCV, but the program there doesn't seem to even run and results in this error:

Is it broken or am I doing something wrong when running the program? Thanks!

EDIT: Using the newer tutorial changes the error to this:
