The MediaStreamTrack.onended event handler is used to specify a function which serves as an EventHandler to be called when the ended event occurs on the track. This event occurs when the track will no longer provide data to the stream for any reason, including the end of the media input being reached, the user revoking needed permissions, the source device being removed, or the remote peer ending a connection.


MediaStreamTrack.onended = function;


A function to serve as an EventHandler for the ended event. The event handler function receives a single parameter: the event object, which is a simple Event object.


This example sets up an event handler for the ended event which changes an on-screen icon to indicate that the track is no longer active.

track.onended = function(event) {
  let statusElem = document.getElementById("status-icon");

  statusElem.src = "/images/stopped-icon.png";
