I have a DJI Mavic pro. Will the HDMI / lightning adapter support video in and out to a FPV head set and from the controller at the same time?

I want to plug this into my iPad as a view screen and run video out at the same time to a head set. Does the lightning port do more then just charge the iPad or will it take input and give the ut put at the same time.
