Hi Alexander,

I *think* the situation is like this: the API is there, and there was a
plan to add a bunch of commonly useful profiles to gst-plugins-base, but
that hasn't happened yet and applications currently either create
profiles on the fly or ship them with the application (e.g.
transmageddon, pitivi).

Someone will hopefully correct me if I'm talking nonsense :)

 Cheers
