Description
Hello!
I'm currently testing some video grabbing, recording and playback on RPi4 w/ Buster. I noticed that if I open a default ofVideoGrabber and ofVideoPlayer at the same time, the two inputs are confused, ie. both are flashing frames from one-another.
I imagine this is something to do with GST using the same pipeline for each. Could anyone recommend what to look at?

Research direction
Reproduce the issue on an RPi4 running Buster with the default ofVideoGrabber and ofVideoPlayer open simultaneously. Inspect how the GST pipelines are created and identify why the inputs exchange frames; done means video capture and playback remain independent.
