Quero saber qual versão do gstreamer eu instalei.
Se houver várias versões, quero saber qual está sendo usado.

Acontece que as coisas estão um pouco confusas. Não são múltiplas versões de gstreamer (principalmente 0.1 e 1.0) e que está a ser utilizado em paralelo (que devem ser tratadas de modo separado) (Fonte) . Quanto aos pacotes, há muitos deles. Aqui estão os pacotes que saíram do dpkg -l | grep gstreamercomando:
