The VideoPlaybackQuality.totalFrameDelay read-only property returns a double containing the sum of the frame delay since the creation of the associated HTMLVideoElement. The frame delay is the difference between a frame's theoretical presentation time and its effective display time.
Syntax
value = videoPlaybackQuality.totalFrameDelay;
Example
var videoElt = document.getElementById('my_vid');
var quality = videoElt.getVideoPlaybackQuality();
alert(quality.totalFrameDelay);
