"Could not get any stream. See error variable to get further details."
I have no idea where to check for this, but I'm guessing YouTube broke the streaming link again?
Also am seeing "streaming failed. Failed to get stream info."
Did you try to update the app from the pinned thread where I always post them? Same thread where you got the original? Google breaks the app fairly often and I post an update to the original link within a day or so.
This is the latest and should get you going.

That did the trick, thanks!
