Re: [linux-audio-user] Recording internet radio using MPlayer

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: MPlayer 1.0pre6-3.4.3 (C) 2000-2004 MPlayer Team CPU: Intel Pentium 4/Xeon/Celeron Northwood (Family: 8, Stepping: 3) Detected cache-line size is 64 bytes CPUflags:  MMX: 1 MMX2: 1 3DNow: 0 3DNow2: 0 SSE: 1 SSE2: 1 Compiled with runtime CPU detection - WARNING - this is not optimal!

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) MPlayer 1.0pre6-3.4.3 (C) 2000-2004 MPlayer Team CPU: Intel Pentium 4/Xeon/Celeron Northwood (Family: 8, Stepping: 3) Detected cache-line size is 64 bytes CPUflags:  MMX: 1 MMX2: 1 3DNow: 0 3DNow2: 0 SSE: 1 SSE2: 1 Compiled with runtime CPU detection - WARNING - this is not optimal!

Anyone have any suggestions on how to get this working? Thank you very much for your time, Kevin
