     GNOME version: ---

I am not sure if this is specific to Ubuntu 16.04 but that is where I am
running on. I am trying to use GStreamer within my application running on
Ubuntu 16.04 to send some video frames over to QGC (QuadGroundControl) to view
the video. 

I am getting a seg fault and do not know where to go from here. I am opening a
bug hoping there is an easy fix in GStreamer or perhaps someone can tell me if
I am missing something.

Not sure if this is related but the rest of the threads look like this

I see this at the top
