[MPlayer-users] MPlayer – changing ‘ao=’ codec order in mplayer.conf does not appear to work for per user config?

Tue Sep 16 10:31:56 CEST 2014

Thanks both for your advice and now modified the test script as follows and
the outputs show a more clear view as to what is not being set I think. It
looks like lighttpd does not set the 'HOME' env var so will head over to
lighttpd support and ask if setting the HOME env is possible as I can't
find any examples on www.

As for the fifo, yes I believe it is being blocked when running test.py via
browser. Running test.py on command line logged in as www-data or pi is OK
and the fifo works. :

test.py:
#!/usr/bin/env python

import subprocess
import select

from os.path import expanduser
home = expanduser("~")

fifoFile = 'file=/run/shm/mpcontrol'

environmentVariables = subprocess.check_output(['printenv'])
whoAmI = subprocess.check_output(['whoami'])

playing_mplayer=subprocess.Popen(['mplayer', '-slave', '-nocache',
'-quiet', '-volume', '60', '-key-fifo-size', '2', '-input', fifoFile,
'-playlist', 'http://tx.whatson.com/icecast.php?i=magic1054.mp3.m3u' ],
stdout=subprocess.PIPE, stdin=subprocess.PIPE, stderr=subprocess.STDOUT)

mpText=""
counting = 1
while counting < 300:
      counting = counting + 1
      if 'Starting playback...' in mpText : break
      while any(select.select([playing_mplayer.stdout.fileno()], [], [],
0.01)):
            mplayerResponse = playing_mplayer.stdout.readline()
            if (mplayerResponse is None) or (len(mplayerResponse) == 0) :
mplayerResponse = ""
            if mplayerResponse != "":
               print mplayerResponse
               mpText = mpText+mplayerResponse+'<br>'
            break

with open('/var/www/error_log','a',0) as g:
     g.write('User: '+whoAmI+'<br>\nEnv variables:
'+environmentVariables+'<br>\nhome dir is:
'+home+'<br>\ntest.py:<br>\n'+str(mpText)+'<br>\n')
g.close()

Outputs are as follows, first set run from a browser, the second set run
from command line logged in as www-data:
