Had to find where cec-client was located and for Raspbmc its in a couple of locations:

Code:

pi@raspbmc:/$ find . -name cec-client
./opt/xbmc-bcm/xbmc-bin/bin/cec-client
./home/pi/.upgrade/xbmc-13-20140305-nc3/xbmc-bcm/xbmc-bin/bin/cec-client
./home/pi/.upgrade/xbmc-13-20140213-nc3-2/xbmc-bcm/xbmc-bin/bin/cec-client
./home/pi/.upgrade/xbmc-13-20140306-nc3b/xbmc-bcm/xbmc-bin/bin/cec-client
./home/pi/.upgrade/xbmc-13-20140228-nc3/xbmc-bcm/xbmc-bin/bin/cec-client

The .upgrade path isn't viable, so made changes and set as

Code:

#!/bin/bash

/opt/vc/bin/tvservice $1

case "$1" in
  "--off")        echo "standby 0" | /opt/xbmc-bmc/xbmc-bin/bin/cec-client -s >/dev/null;;
  "--preferred")    echo "on 0" | /opt/xbmc-bcm/xbmc-bin/bin/cec-client -s >/dev null;;
esac
echo "$(date) called with $1 param" >> /tmp/tvservice.log

But still have

Code:

You've got a typo in the path for cec-client - it should be:

Code:

/opt/xbmc-bcm/xbmc-bin/bin/cec-client

but for --off you've typed:

Code:

/opt/xbmc-bmc/xbmc-bin/bin/cec-client

("/opt/xbmc-bmc" when it should be "/opt/xbmc-bcm")

And I shoud change this to

Code:

sleep 20 && su pi -c /home/pi/texturecache.py @logfile=/home/pi/t4.txt @debug=yes @xbmc.host=localhost @bin.tvservice=/home/pi/mytv.sh rbphdmi 420

??

Actually, you may need to wrap the command being executed in quotes so that it's treated as one argument and not several:

Code:

sleep 20 && su pi -c '/home/pi/texturecache.py @logfile=/home/pi/t4.txt @debug=yes @xbmc.host=localhost @bin.tvservice=/home/pi/mytv.sh rbphdmi 420' &

Give it a go, it should work. Note also that I've added the & on the end which should cause su to fork a new process, other you might find that rc.local processing doesn't finish... in fact with that in mind, I'd change your startup script to be as follows:

Code:

(sleep 20 && su pi -c '/home/pi/texturecache.py @logfile=/home/pi/t4.txt @debug=yes @xbmc.host=localhost @bin.tvservice=/home/pi/mytv.sh rbphdmi 420') &
