I am new to this tech,
but if I can have a video chat from my phone/tablet to my other phone/tablet,
and I can "screen share" whilst in a video chat (like Hangouts) from one to the other,
do any of these "off the shelf googles" support this type of connection?
This way my Mavic Pro receives the signal, sends to my tethered phone/tablet which it shares to my nearby googles.
I'm going to hazard a guess and say NO because those tablets utilize either wi-fi or blue tooth to video chat and share video. The Mavic uses a new system called Occusync and it's a proprietary system from DJI. Therefor, it would not be compatible with the smart devices.
