Hi Folk,
This is my first time on this forum, so if I have logged this incorrectly please let me know.
I am relatively new to obs and Ubuntu.
I have written a script that runs obs as required when run from the command line.
But when I run it from my (user) crontab it fails with the error message:
"qt.qpa.xcb: could not connect to display
qt.qpa.plugin: Could not load the Qt platform plugin "xcb" in "" even though it was found.
This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.
Available platform plugins are: eglfs, linuxfb, minimal, minimalegl, offscreen, vnc, wayland-egl, wayland, wayland-xcomposite-egl, wayland-xcomposite-glx, xcb."
I can see on various linux forums this is a frequent error when running "Qt platform" apps from crontab. Each app seems to have it's own unique fix.
Has anybody come across this with obs?
I am running Ubuntu 20.4 and installed OBS 27.0.1 64bit, using Ubuntu's "snap" installer.
My script: myobs.sh.
# Setup Debug to get error details.
export QT_DEBUG_PLUGINS=1
# Get Date and time for log file names.
now=$( date +%Y-%m-%d-%H:%M:%S )
myobs=`cat /home/pats/Documents/LiveStreamFiles/myobs.sh | grep Normal`
echo "$now, $myobs" >> /home/pats/Documents/myobs.log
# Test for day of week and run OBS Scene for that day.
case $(LC_ALL=C date +"%u") in

If I run this script from the command line it works well, obs runs with the correct Profile and Scene, recording starts, and log files are written as expected.
Now to automate using crontab.....
crontab entry:
# run obs at 17:55 every day with the scene for the appropriate day of the week.
55 20 * * * /home/pats/Documents/LiveStreamFiles/myobs.sh 2>&1 &
Obs does not run but the log files show:
1. myobs.log:
2021-09-14-00:45:01, rosary=`cat /home/pats/Documents/LiveStreamFiles/myobs.sh | grep Normal`
So, cron job is run.
2. myobsDateAandTime.log:
is created with errors.

My attempts so far to fix this have been
Search the internet for the error shown in the log.
1. Remove and re-install obs with the included plugins from the Snap Store. Still did not work.
2. Remove and re-install obs direct from obs project.com then install the plugins I require as per the error message suggestions. Still did not work.
3. Remove and re-install obs with the plugins I require from the Snap Store. Still didn't work.
After each of the above 3 tries the error was the same (identical).
Several forums suggest the Qt Platform is loaded into directories for each App that uses it and the ENV PATH should reflect the appropriate directory structure for the App, obs in my case. Do I need to install the Qt Development platform? But surely not.
I am guessing this is valid information but unfortunately I can't work out what that path is therefore don't know what to add to PATH.
Also I don't understand how myobs.sh script works when I run it from the command line but does not run successfully from crontab.
a. permissions?
b. shell?
c. something else?
Any ideas or suggestions would be gratefully received.
Thanks in advance.

My attempts so far to fix this have been
Search the internet for the error shown in the log.
1. Remove and re-install obs with the included plugins from the Snap Store. Still did not work.
2. Remove and re-install obs direct from obs project.com then install the plugins I require as per the error message suggestions. Still did not work.
3. Remove and re-install obs with the plugins I require from the Snap Store. Still didn't work.
After each of the above 3 tries the error was the same (identical).
Several forums suggest the Qt Platform is loaded into directories for each App that uses it and the ENV PATH should reflect the appropriate directory structure for the App, obs in my case. Do I need to install the Qt Development platform? But surely not.
I am guessing this is valid information but unfortunately I can't work out what that path is therefore don't know what to add to PATH.
Also I don't understand how myobs.sh script works when I run it from the command line but does not run successfully from crontab.
a. permissions?
b. shell?
c. something else?
Any ideas or suggestions would be gratefully received.
Thanks in advance.
