gnu parallel: how to control output of program?

Question

Fast and simple. This command works

locate -i mymovieormysong|parallel mplayer

the song (or movie) play, but i cannot control mplayer with keyboard. How to do (if possible) this?

Actually when i use keyboard to go forward or backward I obtain this

^[[C^[[C^[[C^[[C^[[C^[[C^[[C^[[D^[[D^[[D

Edit1: using -u (un-group) option, the output appear but when I press keyboard for control mplayer still appear [C and [D

Answer 1

I reckon it is unlikely that you want more than one mplayer running.

Normally GNU Parallel takes the tty of the process (due to process group logic). --tty hands the tty to the tty running. So if mplayer reads from the tty, then this might work:

locate -i mymovieormysong|parallel --tty mplayer
