Пример iOS-приложения для

...

видеозвонков

На скриншоте ниже представлен пример интерфейса до совершения звонка.

Интерфейс приложения такой же, как в примере Phone, за исключением того, что воcпроизводятся два видео

слева отображается видео с камеры данного пользователя
справа воспроизводится видео от другой стороны
