Apologies, I am being vague. I am after MPEG-TS packet processing in the bus
event handler so as to get the EIT packages and create the various tables so
as to construct the EPG. So the MPEG-TS API to GstMessage instances.

I have started tinkering with using std::unique_ptr with explicit deleter to
get lightweight RAII using the C API in C++.

I got so wrapped up in the Glib::RefPtr itself and forgot the obvious, every
instance has a gobj method so it is easy to get the GstMessage* from the
Glib::RefPtr<Gst::Message>const&. I was being silly.

But that is why the instructions are needed:

./autogen.sh: 5: ./autogen.sh: mm-common-prepare: not found
