Yes. We call that "input pipeline" or something like that, rather than
"mini-VLC", but that's the idea.

You generally have a packetizer between demux and mux, by the way.

It will be more efficient, because you share the memory, and the common
parts. However, it has one drawback: if there is a bug (ok, there are
no bugs in VLC, but anyway) and VLC crashes, all you streaming crash,
not only the faulty one.
