A few instanceof errors on IE 11 and Safari

[dancrew32]

First off, thanks for making this great player!

Getting a few error logs at my ErrorBoundary around ReactPlayer in IE 11 and Safari/Safari Mobile/Chrome for iOS.

Current version in package.json is "react-player": "^1.6.1"

IE 11:
Invalid operand to 'instanceof': Function expected

Mozilla/5.0 (Macintosh; Intel Mac OS X 10_10_5) AppleWebKit/603.3.8 (KHTML, like Gecko) Version/10.1.2 Safari/603.3.8
Mozilla/5.0 (iPhone; CPU iPhone OS 10_3_3 like Mac OS X) AppleWebKit/603.3.8 (KHTML, like Gecko) Version/10.0 Mobile/14G60 Safari/602.1

Right hand side of instanceof is not an object

While attempting to load an .mp4 file, I believe this error comes from this MediaStream instanceof check here:

https://github.com/CookPete/react-player/blob/9618272e6e4b518e493d3130b96dd2ebeb97b506/src/players/FilePlayer.js#L17-L19

I'll try and do a bit more debugging, but was wondering if you've experienced this on similar platforms.

Should I make a PR to chain another typeof window.MediaStream !== 'undefined' before the instanceof check?

Still seeing these come in on 1.6.2

Having the same issue. But for me it's iOS 10. Works fine with iOS 11...
