Your description is a bit vague. But anyway you can write a custom bin (subclass
GstBin) and there do what you want. In that regard it does not matter if you use
a object property on the bin, an action-signal or an event to ask the bin to
change the internal graph. Events have the advantage that they can be synced
with the data flow.
