Do you need the background to be static or animated? If static is good enough, you can do this now by following what FreeTransformVideoGlFragment does. If it needs to be animated and show blurred and zoomed version of original video frame, that will probably require writing a new filter. I will have to think about this, it is a very interesting problem and feels like LiTr "almost" supports this.
