I had this problem too back when I was using the composite input from
my cable box. Now I don't have a cable box anymore and I'm using the
tuner on the PVR-150 so I don't have this issue any more. I came
across this hack when I was trying to deal with the problem:
#!/bin/sh
# Some variables used to remember if the device is in use or not
record_video0=NO
# Loop forever
while true
do
# Is the video device in use ?
fuser /dev/video0 2>/dev/null >/dev/null
if [ $? -eq 0 ]
then
# Something is using video device and this is the first time
we notice this
if [ "$record_video0" = "NO" ]
then
date
echo " recording on video0"
sleep 5
/usr/local/bin/ivtvctl -d /dev/video0 -q 0
echo
fi
record_video0=YES
else
# Not recording
if [ "$record_video0" = "YES" ]
then
date
echo " not recording anymore on video0"
echo
fi
record_video0=NO
fi
sleep 1
done
I put this in a script called sound_fixer and started this in my
.xinitrc (or .xserverrc, I forget). You might have to play with the
"-q" value in the ivtvctl command to figure out which one works for
you.
Hope this helps,
Akshat
