How to install decoder?

[TheFern2]

If I run uxplay on debug mode, I can see I am missing decoder H.264. I am not sure what to install this decoder, any help is appreciated.

Running Kubuntu 20.04.

Ok, so I fixed the issue by actually installing gstreamer packages. Probably a good idea to add some of these instructions for people unfamiliar with gstreamer.
