I just want a style based way to say: "don't show controls", which apparently won't be possible anymore. I'm also not concerned about a FOUC or reflow, i'm specifically concerned about 50 video frames showing a controlbar on mobile device in nigeria that takes 70 seconds to load the entire page. Which would result in one video after the other then loads the JS player. I want to eliminate that temporary moment of controls, after which the user has to reset his expectations with a new set of controls. And I need to keep my DOM clean of non-semantic <img> elements.

I guess the only other alternative that might get me what i want is to use a top loading synchronous JS fragment, but i don't think our performance team will like that. ..

I know, our requirements are somewhat crazy :)
