The RemotePlayback interface of the Remote Playback API allows the page to detect availability of remote playback devices, then connect to and control playing on these devices.

EventTarget RemotePlayback

Instance properties

The user agent is attempting to initiate remote playback with the selected device.


The transition from local to remote playback has happened, all commands will now take place on the remote device.

Instance methods

Also inherits methods from its parent interface, EventTarget.

Cancels the request to monitor the availability of remote playback devices.


Prompts the user to select and give permission to connect to a remote playback device.


Also inherits events from its parent interface, EventTarget.

The following example demonstrates a player with custom controls that support remote playback. Initially the button used to select a device is hidden:

<video id="videoElement" src="">
  <button id="deviceBtn" style="display: none;">Pick device</button>

The RemotePlayback.watchAvailability() method is used to watch for available remote playback devices. If a device is available, use the callback to show the button.

const deviceBtn = document.getElementById("deviceBtn");
const videoElem = document.getElementById("videoElement");

function availabilityCallback(available) {
  // Show or hide the device picker button depending on device availability. = available ? "inline" : "none";

videoElem.remote.watchAvailability(availabilityCallback).catch(() => {
  /* If the device cannot continuously watch available,
  show the button to allow the user to try to prompt for a connection.*/ = "inline";
