Где находится веб-камера в API потоковой передачи YouTube?

Я не могу загрузить видео прямой эфир на ютубе. Я просмотрел документацию YouTube, попытался выполнить поиск в Google, но безуспешно.

У меня есть полный пример кода PHP для потоковой передачи видео в прямом эфире на YouTube, и видео транслируется, но сообщение

Пожалуйста подождите, скоро начнется

Я использую этот код

<?php

require_once 'Google/Service/Resource.php';
require_once 'Google/Service.php';
require_once 'Google/Client.php';
require_once 'Google/Service/YouTube.php';
session_start();

1. Создание трансляции с фрагментом и статусом I.e метод вставки.
2. Создание Live Stream с помощью cdn (1080p, rtmp) и сниппета со вставкой I.e.
3. Связывание их вместе с методом широковещательной привязки.

Когда я иду в свой https://www.youtube.com/my_live_events он показывает новое созданное событие, но я не понимаю, где отсутствует камера, чтобы использовать прямую трансляцию.
