Disable Video Full-Screen

How can disable the full-screen playback option on the Video controls for the su-video shortcode?

I also would like to make the video responsive (so it shrinks, as it currently will just cutoff), but the CSS I used for embedded youtube videos is not working. Obviously, I don’t use an iframe here, but I couldn’t get the same concept to apply by placing the shortcode inside a div either & then giving the class a different name (no iframe in the name).

It was this:

.blog-video-container {
	position: relative;
	padding-bottom: 56.25%; /* 16:9 */
	padding-top: 25px;
	height: 0;
}

.blog-video-container iframe {
	position: absolute;
	top: 0;
	left: 0;
	width: 100%;
	height: 100%;
}
