{{ APIRef("HTML DOM") }}

The {{domxref("HTMLVideoElement")}} method getVideoPlaybackQuality() creates and returns a {{domxref("VideoPlaybackQuality")}} object containing metrics including how many frames have been lost.

The data returned can be used to evaluate the quality of the video stream.

Syntax

getVideoPlaybackQuality()

Parameters

None.

Return value

A {{domxref("VideoPlaybackQuality")}} object providing information about the video element's current playback quality.

Examples

This example updates an element to indicate the total number of video frames that have elapsed so far in the playback process. This value includes any dropped or corrupted frames, so it's not the same as "total number of frames played."

const videoElem = document.getElementById("my_vid");
const counterElem = document.getElementById("counter");
const quality = videoElem.getVideoPlaybackQuality();

counterElem.innerText = quality.totalVideoFrames;
