Hmm interesting indeed, if it helps it's a "JW player 8.28.1" (homepage link). The video in question has a share link with this. Could be a network you're on blocking it, I see these video players the most on news sites and unfortunately recipe sites as well. I don't think you're missing out on a lot with not seeing these types of plague video players that pop up in a corner if you try to scroll past it though lol.
