WARNING: apt does not have a stable CLI interface. To provide more information to you, here are the gstreamer packages that I have installed: $ apt search gstreamer1.0 | grep nstalled Nevertheless, I took the code from, checked out version 1.14, built an own DEB-packet from it and installed it. I am aware of a similar forum thread that proposes to install gst-omx, which however is not available for my Ubuntu 18.04 installation and also seems outdated.

The guide suggests I should check my gstreamer version, which is $ gst-inspect-1.0 -version I followed the Accelerated Gstreamer User Guide (Release 32.1), which however was unsuccessful. I am trying to make use of the built-in H.264 encoder in my Jetson TX2.
