The VideoPlaybackQuality interface represents the set of metrics describing the playback quality of a video.
An instance is created using the HTMLVideoElement.getVideoPlaybackQuality() method.
The VideoPlaybackQuality interface doesn't inherit any property.

unsigned long giving the number of video frames dropped since the creation of the associated HTMLVideoElement.VideoPlaybackQuality.corruptedVideoFrames Read only
