MPlayer and most programs do not require ttys. It won't care what type 
of file stdin is connected to. The simplest thing to do is to use a pipe 
to connect a controlling process and a subordinate mplayer. Of course, 
you have to make sure mplayer uses the correct output video device, but 
that is separate from any tty.

Alternatively, you can use FIFOs, or named pipes. It is also possible to 
use pty (pseudo terminal) master/slave pairs, but I doubt that is necessary.
