MediaStream: removetrack event

Baseline

Widely available

This feature is well established and works across many devices and browser versions. It’s been available across browsers since July 2020.

The removetrack event is fired when a new MediaStreamTrack object has been removed from a MediaStream.

This event is not cancelable and does not bubble.

Syntax

Use the event name in addEventListener():

addEventListener("removetrack", (event) => { })

Alternatively, assign to the event handler property of the interface:

onremovetrack = (event) => { }

Using addEventListener():

const stream = new MediaStream();

stream.addEventListener("removetrack", (event) => {
  console.log(`${event.track.kind} track removed`);
});

Using the onremovetrack event handler property (but note that this replaces other event listeners added using onremovetrack, if any):

const stream = new MediaStream();

stream.onremovetrack = (event) => {
  console.log(`${event.track.kind} track removed`);
};
