Hi DaneLLL, thank you for the clue. I tried both ways - installing from source and installing with “gst-install” but I wasn’t successful. I got “installation successful” in the command-line but “gst-launch-1.0 --version” showed always the same result: version 1.14.1 . Then I tried to uninstall gstreamer first before installing version 1.16 but after the uninstallation, I lost the desktop-environment and the jetson nano only booted to command-line. It seems quite difficult to uninstall gstreamer in a proper way. What would be the best approach to successfully upgrading gstreamer 1.14.1 to version 1.16? Thanks!
