Узнать параметры видеоклипа, просматриваемого в Chrome, Opera и FireFox

[maks05]

Как узнать параметры видео-ролика, просматриваемого с сайта через Chrome, Opera и FireFox? Имеется ввиду, что бы параллельно с просмотром взглянуть на используемые кодаки, частоту кадров, битрейд, контейнер. Приоритет использования браузеров именно в такой последовательности. Сайты, в принципе, любые, но приоритетней Rutube, ivi.ru, YouTube.

Непосредственно через браузер и узнать. Например, в русифицированном Firefox:
Инструменты->Информация о странице->Мультимедиа
и там можно найти.

Только я что-то не вижу, битрейта и т.п. Только объём файла. Или эти данные здесь как-то зашифрованы? А может вообще не там ищу?

Вот, есть ещё информация:
