The cancelWatchAvailability() method of the RemotePlayback interface cancels the request to watch for one or all available devices.

id Optional

The callbackId of a particular remote playback device.

If a callbackId of a specific device is passed in, then that device will be removed from the list of watched devices. Otherwise, the whole list will be cleared.

A Promise that resolves with undefined.

InvalidStateError DOMException

Thrown if disableRemotePlayback is true for the media element.

NotFoundError DOMException

Thrown if an id is passed but it does not match any available callbackId.

Once a remote playback device has been identified and is connected, the monitoring of available devices can be stopped using cancelWatchAvailability().

function switchToRemoteUI() {
  // Indicate that the state is 'connecting' or 'connected' to the user.
  // For example, hide the video element as only controls are needed.
  videoElem.style.display = "none";

  // Stop monitoring the availability of remote playback devices.
  videoElem.remote.cancelWatchAvailability();
}
