Hi,

I'm not sure if this is the right forum for this but hopefully some of
you have done this before.

I've managed to get everything working as it should when recording internet
from the command line using mplayer. But I still have a problem recording
using cron to record at specific times.

I issue the following statement on command line :

mplayer http://oggtrial.nm.cbc.ca:80/cbcr2-toronto.ogg -ao pcm
-aofile /home/kbs464/tmp/mystream.wav -vc dummy -vo null;

With the following satisfactory results:

and a file /home/kbs464/tmp/mystream.wav gets created.

However, if I run the exact same command as part of the cron scheduler I get
nothing. No file gets created by mplayer.

My crontab looks like this:

55 11 * * 1-5 /home/kbs464/scripts/streamrecorder &> /dev/null
30 12 * * 1-5 killall -9 mplayer

And the streamrecorder script like so:

#!/bin/bash

mplayer http://oggtrial.nm.cbc.ca:80/cbcr2-toronto.ogg -ao pcm
-aofile /home/kbs464/tmp/mystream.wav -vc dummy -vo null;
oggenc /home/kbs464/tmp/mystream.wav -o /home/kbs464/BraveNewWaves_`date
+%b_%d_%y`.ogg;
rm -f /home/kbs464/tmp/mystream.wav;

If, in crontab, I change the redirect of the streamrecorder script to a text
file I get the following back:

(contents of error file)

And so on... the cache fill never moves from 0 even though the exact command
that I ran on the command line is running via cron.

Anyone have any suggestions on how to get this working?

Thank you very much for your time,
Kevin
