Media error code constants

MEDIA_ERR_NETWORK 2 Some kind of network error occurred which prevented the media from being successfully fetched, despite having previously been available.
MEDIA_ERR_DECODE 3 Despite having previously been determined to be usable, an error occurred while trying to decode the media resource, resulting in an error.

This example creates a <video> element, establishes an error handler for it, and then sets the element's src attribute to the video resource to present in the element. The error handler outputs a message

const obj = document.createElement("video");
obj.onerror = () => {
  console.error(`Error with media: ${obj.error.code}`);
obj.src = "";
