Как проверить версию gstreamer?

Я хочу знать, какую версию gstreamer я установил.

Если окажется, что у меня есть несколько версий, я хочу знать, какая из них используется.

Редактировать:

Оказывается, все немного грязно. Существует несколько версий gstreamer (в основном 0.1 и 1.0), и они используются параллельно (их следует рассматривать как отдельные) (Источник) . Что касается пакетов, то их много. Вот пакеты, которые вышли из команды dpkg -l | grep gstreamer:
