Removing elements

[Florian Echtler]

Was just looking at this yesterday, here's a minimal example:

https://github.com/GStreamer/gst-python/blob/master/examples/dynamic_src.py

IIRC the method is to install an idle probe on the upstream pad, unlink the pads 
when the idle probe is triggered, and set the state to NULL later (in an idle 
callback or such).

Best, Florian
