VideoPlaybackQuality

{{APIRef("HTML DOM")}}

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

Instance properties

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

• {{domxref("VideoPlaybackQuality.creationTime", "creationTime")}} {{ReadOnlyInline}}
  • : A {{domxref("DOMHighResTimeStamp")}} containing the time in milliseconds between the start of the navigation and the creation of the object.
• {{domxref("VideoPlaybackQuality.droppedVideoFrames", "droppedVideoFrames")}} {{ReadOnlyInline}}
  • : An unsigned long giving the number of video frames dropped since the creation of the associated {{domxref("HTMLVideoElement")}}.
• {{domxref("VideoPlaybackQuality.totalVideoFrames", "totalVideoFrames")}} {{ReadOnlyInline}}
  • : An unsigned long giving the number of video frames created and dropped since the creation of the associated {{domxref("HTMLVideoElement")}}.

Obsolete properties

• {{domxref("VideoPlaybackQuality.corruptedVideoFrames", "corruptedVideoFrames")}} {{ReadOnlyInline}} {{Deprecated_Inline}}
  • : An unsigned long giving the number of video frames corrupted since the creation of the associated {{domxref("HTMLVideoElement")}}. A corrupted frame may be created or dropped.
• {{domxref("VideoPlaybackQuality.totalFrameDelay", "totalFrameDelay")}} {{ReadOnlyInline}} {{deprecated_inline}} {{Non-standard_Inline}}
  • : A double containing the sum of the frame delay since the creation of the associated {{domxref("HTMLVideoElement")}}. The frame delay is the difference between a frame's theoretical presentation time and its effective display time.
