Я пытаюсь создать приложение на python, которое позволит мне транслировать видео с моей камеры на YouTube.До сих пор с помощью документации разработчика Google я успешно вставил, транслировал в прямом эфире и привязал его к трансляции.
В настоящее время я считаю, что прямой эфир - это просто событие, и мне придется загружать видео отдельно (я незнать, прав я или нет по этому поводу).Если вы можете объяснить мне, как добавить в него видео (пожалуйста, постарайтесь оставить его бесплатным для моего университетского проекта, я не знаю, платят ли в прямом эфире через какой-либо сервис или нет).Я где-то читал о ffmpeg, но не могу понять, как его использовать.Я работаю на Python 3.4, ОС Windows 10.
это мой код:
