If I start a process with xterm like this (where omxplayer is the process xterm is starting):
xterm -fullscreen -fg black -bg black -e omxplayer -o hdmi -r %f
Is it possible for me to write to xterm's standard input via a different process to control the omxplayer? If so, how?
(I'm pretty unfamiliar with linux terminology so please excuse if I'm stating this incorrectly.)
As per @strugee's comment, I'm not aiming to write to xterm's standard input, but rather I'm aiming to write to omxplayer's standard input.
