Posted 2021-05-20

// Check if the browser understands the video element.
function understands_video() {
  return !!document.createElement('video').canPlayType; // boolean
}

if ( !understands_video() ) { 
	// Must be older browser or IE. 
	// Maybe do something like hide custom
	// HTML5 controls. Or whatever...
	videoControls.style.display = 'none';
}
