Scripts doesn't work in domoticz

Hey guys, I've a problem.
I wrote a script.sh and it works really well in terminal. I set a dummy switch and in the on action I set the script.
Code: Select all
#!/bin/sh
# Start Recording RTSP stream via VLC
vlc rtsp://192.168.1.3/unicast --sout=file/mp4:/home/pi/Desktop/Soggiorno-$(date +%m%d%H%M%S).mp4 -I dummy --stop-time=10 vlc://quit
exit 0
that's the script. Already set chmod 777 script.sh and chmod +x script.sh.
In domoticz log I see
Code: Select all
Executing script: /home/pi/domoticz/scripts/soggiorno.sh
and no error but nothing happens.

If you run in terminal:
Code: Select all
sudo /home/pi/domoticz/scripts/soggiorno.sh
it works?

Can the script find vlc when started from domoticz?

Use the absolute path to executables.
Make sure the users that run's Domoticz has rights to the scripts and executables.
Add a echo 'script executed' > /temp/test.log to see of the script is called from domoticz

Try to put output to logfile...for example:
Code: Select all
vlc rtsp://192.168.1.3/unicast --sout=file/mp4:/home/pi/Desktop/Soggiorno-$(date +%m%d%H%M%S).mp4 -I dummy --stop-time=10 > /home/pi/domoticz/scripts/vlc.log
and look into vlc.log after execution.
A question...but with that vlc command...vlc opens graphically into your desktop?

Log file is empty.
if I start the script in terminal vlc doesn't open graphically

Yes it works
EDIT
I'm sorry I was wrong. If I use SUDO I recive this "VLC is not supposed to be run as root. Sorry.
If you need to use real-time priorities and/or privileged TCP ports
you can use vlc-wrapper (make sure it is Set-UID root and
cannot be run by non-trusted users first)."
Nut starts fine without SUDO

Domoticz on raspberry runs as root..so scripts run as root...
You can try this:
Code: Select all
sed -i 's/geteuid/getppid/' /usr/bin/vlc
(rif.
http://unix.stackexchange.com/questions ... er-in-root)
and run again as root...but make a backup of /usr/bin/vlc before...
Or recompile vlc...
Or use avconf instead of vlc...
..

Yes man! you did it! but now I'm not able to open file due to permission I think.
How can I set permission on file that has (date +%m%d%H%M%S) in the name?

It seems that change permission to folder did the trick

Just another problem. I've two scripts calling vlc to record two cameras but domoticz doesn't run them at the same time. If I open two terminals and lunch one script per istance I can do that. I also enabled multiple istances on vlc. Ideas?

Done. Simply add an & at the end of the scripts.
