Hi,

I managed to solve the problem. In the man of mplayer I found how to
quit after X seconds: "-endpos X". See my solution below.

Best,

proc = Popen(args, stdout=PIPE, stderr=PIPE)
out, err = proc.communicate()
exitcode = proc.returncode

for line in out.split("\n"):
# print(line)
if line.startswith('ICY Info:'):

title = match.group(1)
return title
