-----------------------------------------
Hey, Adam! Please check stopCapture in CaptureAgentImpl. There are cases where
you can exit the method without calling Pipeline.setState(State.NULL), and,
according to the java-gstreamer wiki:

Finally, after processing has completed, we need to clean up the pipeline by
setting its state back to the default state, or else gstreamer will get upset.
pipe.setState(State.NULL);
{quote}
I think this is the problem.
Also, I don't know why you use the pipeline bus to send an EOS event, when the
preferred way to stop the pipeline is setting its state to stopped, or using
the .stop() method. I see no reason for using such a convoluted syntax there...
