this does nothing until outputstream is opened for reading by some other

No, use the first mplayer for that. The second player that determines the

Keep in mind that the player on the client side needs to buffer a bit of
data, so the volume, speed, equalizer changes will only take effect after
some seconds.

will be of no benefit and that are not as easy as you think.
