VideoPlaybackQuality.totalFrameDelay - Web APIs 编辑

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This feature is obsolete.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);
