Viper's Video Quicktags and OGraphr

Hello,
thank you for your plugin, it helps a lot.
I have a problem when I try to share a video on facebook—it doesn’t show up the thumbnail. Most importantly, I’d like that the video would be displayed inline in the timeline, once published on facebook.
I thought your plugin could help me to add all the meta tags needed, but I don’t know what I’m doing wrong.
From what I read, in order to let facebook read the content, one should add the right meta tag (in my case og:video?). Problem is, of course, how to do it dynamically.
Can your plugin do that?
Maybe there’s some interference with the video plugin I’m using?

Here the link to one of the video post — https://www.kuboloi.com/borsalino/
I use custom fields to separate description from media content.

Here’s a list of the active plugins:
