I have two option to solve this. Adopt the proposed patch (it's actually 
incomplete, the real patch is more intrusive). Or create a new 
GstAsyncVideoDecoder completly designed toward supporting a task running 
on the src pad. Though, I didn't find the time yet.

This second option would create an analogy with the need for 
GstAsyncBaseTransform.

cheers,
