I think you can do this without the -x option.  While in the shell on
the remote machine, run this

  export DISPLAY=:0.0

Then any X app you run will have the display show up on the remote
machine.  Note: this does assume that an X server is running on the
remote.  Also, when you restart camstream you will want to add nohup,
to wit:

  nohup camstream &

or it will terminate when you log out.
