A problem I came across is that sometimes the device driver modules
needed a slight pause inbetween
loading to allow the /dev char devices to be created, there are two ways
round this.
1) stick a couple of sleep statements in your rc.local, ie
modprobe ivtv
sleep 5
modprobe ivtv-fb
sleep 5
2) stick a little loop in there to check for the devices and loop until
they're there, eg
(this is the script I use)
#/bin/bash
# Name: load-ivtv
# Author : David Sharp @ 04/01/2005
# Purpose : Load ivtv driver checking for char devices before continuing
to load
# next module.
# Mod.Hist:
# 04/01/05: New script
# Functions
function wait_for_device(){
Device=${1} # device is full path name, eg /dev/fb1
Count=1
Count_Timeout=100 # number of seconds to wait before timing out
# needed as otherwise this will loop forever
# if for whatever reason the device never appears
echo -n "Waiting for device ${Device} to appear."
while [ ! -c ${Device} ]
do
let Count=Count+1
sleep 1
echo -n "."
if [ ${Count} = ${Count_Timeout} ]
then
echo
echo "Timeout waiting for device ${Device}"
sleep 1
return 1
break
fi
done
}
# Main script
modprobe ivtv
wait_for_device /dev/video0
RETVAL=$?
if [ $RETVAL -eq 0 ]
then
/usr/lib/ivtv/ptune.pl -f pal-europe-west --channel 53 # tune in
channel otherwise errors in log
dd if=/dev/video0 of=/dev/video16 bs=64k & # output to /video16
otherwise ivtvdev/X tv out doesn't work
sleep 5
kill %1
modprobe ivtv-fb
wait_for_device /dev/fb1
fi
