MediaStreamTrack.stop()

The MediaStreamTrack.stop() method stops the track.

Syntax

track.stop()

Description

Calling stop() tells the user agent that the track's sourceā€”whatever that source may be, including files, network streams, or a local camera or microphoneā€”is no longer needed by the MediaStreamTrack. Since multiple tracks may use the same source (for example, if two tabs are using the device's microphone), the source itself isn't necessarily immediately stopped. It is instead disassociated from the track and the track object is stopped. Once no media tracks are using the source, the source may actually be completely stopped.

Immediately after calling stop(), the readyState property is set to ended.

Examples

Stopping a video stream

In this example, we see a function which stops a streamed video by calling stop() on every track on a given <video>.

function stopStreamedVideo(videoElem) {
  const stream = videoElem.srcObject;
  const tracks = stream.getTracks();

  tracks.forEach(function(track) {
    track.stop();
  });

  videoElem.srcObject = null;
}

This works by obtaining the video element's stream from its srcObject property. Then the stream's track list is obtained by calling its getTracks() method. From there, all that remains to do is to iterate over the track list using forEach() and calling each track's stop() method.

Finally, srcObject is set to null to sever the link to the MediaStream object so it can be released.
