This works great.  I have three video feeds streaming over udp to my client
machine, which is running my Qt app which now has three widgets, one for
each stream.

I set the uri like so:

m_pipeline->setProperty("uri", "udp://0.0.0.0:5001);

streaming to different ports (i.e. 5002, 5003) for each widget.

The only problem now is that things seem much choppier than when I run all
this using gst-launch from the command line (also over UDP).  Is there an
alternative to playbin2 which would be less choppy?

i.e. right now I'm doing like in the example:

 m_pipeline =
QGst::ElementFactory::make("playbin2").dynamicCast<QGst::Pipeline>();

Thanks again.
