Python: Send command to mplayer under slave mode

Question

I\'m trying to send command via pipe to mplayer when running it under slave mode like this:

import subprocess, time
# start mplayer
song = \'mysong.mp3\'
cmd         


        

Answer 1

I'm now doing it this way and I start to get output:

 while True:
    cmd = '\nget_meta_artist\n'
    p.stdin.write(cmd)
    output = p.stdout.readline()
    print("output: {}".format(output.rstrip()))
    sys.stdout.flush()

Although I still need to figure out a way to bypass the first flush of mplayer's own initialization stdout but I consider my problem solved.

Thanks to glglgl for giving me useful hints.
