Maybe something with the imagefreeze element?

You could change the pipeline when the pause event comes and replay the
last buffer over and over using imagefreeze, with the downstream
pipeline (in particular gltransform) staying the same, just the
"source" would change.

I've never done it so I am afraid I cannot be more specific, sorry.
