VideoPlaybackQuality.totalFrameDelay

This is an experimental technology
Because this technology's specification has not stabilized, check the compatibility table for usage in various browsers. Also note that the syntax and behavior of an experimental technology is subject to change in future versions of browsers as the specification changes.

Obsolete since Gecko 30 (Firefox 30 / Thunderbird 30 / SeaMonkey 2.27 / Firefox OS 1.4)
This feature is obsolete. Although it may still work in some browsers, its use is discouraged since it could be removed at any time. Try to avoid using it.

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);
