Opentok 3d (stitched stereophonic) published stream. Creating IOS app to play 3d stream

I am using opentok to publish a 3d stream (stitched). This is a web implementation. (WebRTC). All is fine on Andriod.
WebRTC is not available on IPone.

I have created an app to play the stream using opentok.ios (2d presentation). I am in the hunt for techniques, recommendations, samples of how to present the opentok 3d stream in a split screen format for VR goggles.
Some topics : AVFoundation, OPenGL ES, MPMoviePlayer.

Any suggestions would be appreciated.
