The VideoPlaybackQuality interface's read-only corruptedVideoFrames property the number of corrupted video frames that have been received since the <video> element was last loaded or reloaded.
The number of corrupted video frames that have been received since the <video> element was last loaded or reloaded.
It is up to the user agent to determine whether or not to display a corrupted video frame. If a corrupted frame is dropped, then both corruptedVideoFrames and droppedVideoFrames are incremented.
This example determines the percentage of frames which have been corrupted, and if the value is greater than 5%, calls a function called downgradeVideo() that would be implemented to switch to a different video that might tax the network less.
const videoElem = document.getElementById("my_vid");
const quality = videoElem.getVideoPlaybackQuality();
if (quality.corruptedVideoFrames / quality.totalVideoFrames > 0.05) {
downgradeVideo(videoElem);
}
