Take a look at /usr/share/Performer/src/pguide/libpf/C/movietex.c

That brings me to a related question that's been keeping me busy for the
last couple of days.

I've developed an application that (supposedly) shows a multi-pipe video
texture. But the texture only shows up on the first pipe or rather on
the pipe where the pfTexture was initialized (*not* created, that took
place before pfConfig).

I'm suspecting that the DMbuffer is not allocated from pf shared memory
and so it's only visible for one process. So my question is, how can I
setup a pool of DMbuffers that's allocated from the Performer shared
arena?

Thanks,
-Ulrich
