Thanks Sebastian and Jesper.  This was a great help and I'm able to view
the statistics now.  I'd welcome the new API, since this is a pretty
elaborate way of getting to some nice statistics.

One question - is there a way that I can get access to a shared (read only,
or immutable) version of the statistics from the rtp source?  I'd like to
store that and reference it when I need to read it, rather than needing to
go through the process of getting a new copy of the statistics GstStructure
every time.
