The plugin don't work with current Facebook embed code

I don’t know how the Facebook thumbnail fetching is built into the plugin, but I have the idea that is outdated. It always marks as “passed” on the built-in debug, but when embedding videos with the current embed code it never works. Here’s more info about the embed code: https://developers.facebook.com/docs/plugins/embedded-video-player
