You might find some bits in this blog post interesting:

One problem is that if your pipeline is actually in PAUSED state (which
usually means blocked at the sinks, although it depends a bit on your
exact pipeline), you may not be able to just remove elements from it,
since the streaming thread is 'stuck' inside the element so to say.
You'd either have to flush part of the pipeline to make it come unstuck,
or set it to playing. It's all in the details though.

Cheers
