This is an experimental technology
Because this technology's specification has not stabilized, check the compatibility table for the proper prefixes to use 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 spec changes.

The VideoPlaybackQuality interface represents the set of metrics describing the playback quality of a video.

An instance is created using the HTMLVideoElement.getVideoPlaybackQuality() method.

Properties

The VideoPlaybackQuality interface doesn't inherit any property.

VideoPlaybackQuality.creationTime Read only
A DOMHighResTimeStamp containing the time in miliseconds since the start of the navigation and the creation of the object.
VideoPlaybackQuality.totalVideoFrames Read only
An unsigned long giving the number of video frames created and dropped since the creation of the associated HTMLVideoElement.
VideoPlaybackQuality.droppedVideoFrames Read only
An unsigned long giving the number of video frames dropped since the creation of the associated HTMLVideoElement.
VideoPlaybackQuality.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.
VideoPlaybackQuality.totalFrameDelay Read only Obsolete since Gecko 30
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.

Methods

The VideoPlaybackQuality interface neither implements any specific method, nor inherits any.
