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.

Properties

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

creationTime Read only: A DOMHighResTimeStamp containing the time in miliseconds 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.

Obsolete properties

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.
