I don’t think you can, unfortunately… 
Just looked it up, and there was suggestions that you changed “http://” to “https://”, which shouldn’t really be a problem as the docs has “//” in it. You could change it to “https://” just in case, though.
You could try to iframe the experimental HTML5 player.
