I think it'd be a stretch to say that this prohibits proprietary
gstreamer plugins, but I doubt you could *include* them in a gstreamer
distribution. Third-party ones should still be okay.

So, I'd say that the former is probably prohibited and the latter is
probably allowed. Incorporating proprietary plugins into Debian is
somewhere around the borderline case, but I can't see that ever being
an issue.
