Unable to use gstreamer plugins as user

theidiotcompany · January 19, 2022, 2:43pm

Hi,

Have been banging my head against the wall for a couple hours now, so time to post :-&

We have a third party Jetson nano with Jetpack 4.6 installed out of the box.

When I run gst-inspect as user, it cannot find the some of the modules we need and keeps spitting out errors and the plugins get blacklisted. On the devkit it works fine.

I’ve deleted the .cache/gstreamer-1.0 directory many times and I cannot reinstall the SDK as the device is already in the field in another country.

The application needs to run as a user

To answer my own question:

the user wasn’t in the group “video”, did a usermod and it works!
