canPlayType is not called "against a file". It's called with a single
argument which is a string MIME type. If you pass
"application/octet-stream", it will return "". Its behavior does not
depend on any state of the element it's called on (like what it's
actually pointing to, etc); only on the string passed in.

I think you're misunderstanding what canPlayType does?
