Not going to comment on the AC compressor since that has been covered.
The whining sounds like the alternator going bad, the alternator is on the top right, next to the AC compressor.
Very easy to replace and about $180 after core return. I recommend removing it than taking it to a local auto parts store for match up and core exchange.
After watching the video again, still hard to diagnose from that, it might be a bad idler since the sound gets louder when you move the camera left. If you can get another video and move closer to the right by the alternator to locate the noise.
It also could be a bad clutch bearing in the compressor since I hear a change in tone when the compressor stops.
