The setScreenshareActive() method of the MediaSession interface is used to indicate to the user agent whether the user's screenshare is considered to be active.

Call this method on the navigator object's mediaSession object.

Note that the status of the screenshare is not tracked in the MediaSession itself, but must be tracked separately.

Syntax

setScreenshareActive(active)

Parameters

active

A boolean indicating whether the screenshare is considered active or not.

Return value

None (undefined).

Examples

Below is an example of updating the screenshare active state of the current MediaSession, as well as listening to requests to change the screenshare status with setActionHandler().

let screenshareActive = false;

navigator.mediaSession.setCameraActive(cameraActive);

navigator.mediaSession.setActionHandler("togglescreenshare", () => {
  screenshareActive = !screenshareActive;
  navigator.mediaSession.setCameraActive(screenshareActive);
});
