Make black margins around the video player optional

Hi there,

have you ever been annoyed by not being able to make the video player take up 100% of the viewport width? I often have the Laracasts browser window on two thirds of the screen and my editor on the other third. And to me, it's a bit annoying that, at 1100/1200px width, the video player has those nasty black margins. Sure, I could override that with a user style sheet. But wouldn't it be nice (© Beach Boys) to have the option to make the video take up 100% of the width?

Thanks for reading ... Ollo
