VideoPlaybackQuality

A VideoPlaybackQuality object is returned by the HTMLVideoElement.getVideoPlaybackQuality() method and contains metrics that can be used to determine the playback quality of a video.

The VideoPlaybackQuality interface doesn't inherit properties from any other interfaces.

creationTime Read only

A DOMHighResTimeStamp containing the time in milliseconds between the start of the navigation and the creation of the object.

droppedVideoFrames Read only

An unsigned long giving the number of video frames dropped since the creation of the associated HTMLVideoElement.

totalVideoFrames Read only

An unsigned long giving the number of video frames created and dropped since the creation of the associated HTMLVideoElement.

corruptedVideoFrames Read only

An unsigned long giving the number of video frames corrupted since the creation of the associated HTMLVideoElement. A corrupted frame may be created or dropped.

totalFrameDelay Read only

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.

The VideoPlaybackQuality interface has no methods, and does not inherit any.
