Hi Scott, Sure, that's in fact my eventual goal - but in order to successfully get that far I need to work out how to compile OpenJFX with other GStreamer plugins first, and unfortunately at the moment I seem to be getting stuck at that hurdle!
Time permitting, I do indeed plan to look at addressing 2684 if I can get that far.
