Предварительный просмотр GNOME Sushi не работает для видеофайлов

у меня установлен GNOME-sushi на Ubuntu 20.04 LTS. Первоначально, когда я выбрал видео и нажал пробел , произошла следующая ошибка.

После установки пакетов gstreamer1.0-plugins-bad и gstreamer1.0-plugins-ugly воспроизводится только звук, но не видео.

Следующие компоненты уже установлены (используется dpkg -l | grep gstreamer )
