/// - success: `true` if the operation was successful; otherwise `false`.
/// - statusCode: The status code returned by the device. `nil` if the operation failed.
/// - error: An `NSError` object that describes the error that occurred, or `nil` if the operation was successful.

/// Requests to stop the current video recording session.
/// - Parameters:
/// - completion: A closure that is called when the operation completes.
/// - success: `true` if the operation was successful; otherwise `false`.
/// - statusCode: The status code returned by the device. `nil` if the operation failed.
/// - error: An `NSError` object that describes the error that occurred, or `nil` if the operation was successful.

}Обработчики сообщают состояние команды устройства, но не возвращают путь к видео или разрешение. Текущий открытый API не позволяет выбирать разрешение для отдельного запроса.
