How to set up a video player for Facebook integration?

Question

JavaScript

There is a video service, user unique content.
He should post it, for example, on his Facebook page and our player should be shown immediately.
I set up the meta tags, everything is fine on the player page.

The player loads on the page, but for some reason the screen is empty and the buttons are not active when pressed.
