How to upgrade gstreamer in Jetson nano 2GB

How to upgrade the GStreamer version to 1.18. Right now, it is using 1.14, Is there any documentation or steps to perform the upgrade.

I am using Jeston nano with ubuntu 18.04

We have instructions in gstreamer user guide

A user has tried to upgrade to 1.16:
Gstreamer 1.16 on Jetson AGX Xavier

Since we have performed all tests on 1.14.5, there might be stability issues after manually upgrading to later version. Would suggest you use default 1.14.5.
