Is there a way to send picture_t straight down? If so, how? I could surely do
that.
The audio has exactly the same issue, of course (pushed through araw.c).
Could I do something there as well?

Is there anything wrong about that?

If I am to send data from Demux(), yes. (The alternative is polling, of
course, which is not good at all.)
