Using Gstreamer and souphttpsrc in Jupyter Notebook

[Jimmy Bush]

When I execute

    conda install gst-plugins-good

it causes gstreamer, gst-plugins-base, and gst-plugins good to be
installed.  All are 1.14.5.  Same behavior, as gst-inspect-1.0 reports "No
such element or plugin 'souphttpsrc'.

After uninstalling these conda packages, I also attempted to install
jupyter notebook with pip in my conda workspace.  This installed okay, and
it didn't break my command line usage of souphttpsrc.  In the notebook,
however, when I try to gi.require_version("Gst", "1.0"), it gives me an
error that "Namespace Gst not available", even though I have
gobject-introspection and pygobject installed.  If this is an easier
problem to attack, it would let me use 1.16, which might be preferable
given that a lot of gst_plugins packages aren't available in conda.

Thanks,
Jimmy
