Thank you, Srikanth.

You think key_frame means IDR? Nope. I've asked many times what "key_frame" means but no one has 
offered an answer. But it definitely does not mean IDR. I have videos with frames reported as 
key_frames that are definitely non-IDR. It was considerate of you to reply, though.

I'm running Windows, but I understand your script.
