...and total CPU Time.

Interesting, just noticed that watching a Udemy course uses %98 CPU (in Activity Monitor on a MBP). This even if playback if paused. Wonder if they're doing something similar or it's just a lame implementation?

I've seen some software video decoders do that at times, though if it's happening even while paused it's a little unusual (maybe decoding buffered frames?).
