Description

youtube-dl "https://www.youtube.com/watch?v=mZyvIHYn2zk" fails with a 404 error, but is playable in the browser. I updated to the latest git master and was still able to reproduce this problem.

Server side Youtube issue for format 247.

I don't understand - it plays fine on the web.

It now happens very often.
