/**
 * This hook can be used to implement a UI component which allows the user to manually change their
 * audio/video device. It returns the list of all devices as well as the currently selected one. The input
 * devices will be returned based on what the user is allowed to publish, so a audio only user won't get
 * the audioInput field. This can be used to show the UI dropdowns properly.
 *
 * Note:
 * - Browsers give access to the list of devices only if the user has given permission to access them
 * - Changing devices manually work best in combination with remembering the user's selection for the next time, do
 *   pass the rememberDeviceSelection flag at time of join for this to happen.
 *
 * @param handleError error handler for any errors during device change
