i wouldn't be so bold, since i din't mess directly with the headers. I just used a different API http.ServeContent, that handles the headers for me. It might any other header handled by this API that we were not aware of. We should conduct tests manually setting headers to check which one is the one required by iOS.

or simply leave it be, and document that videos might not work in iOS without extra headers, and let the devs fend for themselves.
