Thanks for the response.<br>
<br>
I'm not sure I follow.. I already have an instance of <font
face="monospace, monospace">Glib.MainLoop</font> for the
pipeline to run already.<br>
<br>
This is constructed on the main thread just after <font
face="monospace, monospace">Gst.init(None)</font><font
face="arial, helvetica, sans-serif"> is called.</font><br>
But.. I am running <font face="monospace, monospace">GLib.MainLoop.run</font> in
it's own thread - is this okay?<br>
That Thread is started from the main application, just before
the pipeline is started.<br>

<br>
Unfortunately, no. The CFRunLoop must be running on the main
thread, otherwise this will not work.<br>
<br>
Cheers<br>

I can see that the python rocket bouncing.. so it's attempting
to kick the display.. but no window.<br>
<br>
Do I need to override something with the

I have attempted to connect this on the bus
'message::need-context', but get no signal..<br>
