gst-examples Issue: Required gstreamer plugin 'nice' not found

[Terence Darwen]

Thanks, David.  As shown in my copied and pasted terminal output below, I
seem to have all of those installed yet it's still not finding the nice
plugin.  I wonder if the issue is related to the fact that I manually built
and installed gstreamer 1.19 and, as shown below, these ones I've installed
are 1.14?
