HTMLMediaElement.currentSrc
  The HTMLMediaElement.currentSrc property contains the
  absolute URL of the chosen media resource. This could happen, for example, if the web
  server selects a media file based on the resolution of the user's display. The value
  is an empty string if the networkState property is EMPTY.
Value
  A DOMString object containing the absolute URL of the chosen media
  source; this may be an empty string if networkState is EMPTY;
  otherwise, it will be one of the resources listed by the
  HTMLSourceElement contained within the media element, or the value or src
  if no <source> element is provided.
Examples
var obj = document.createElement('video');
console.log(obj.currentSrc); // ""
