For one festival I need to provide WebVR slideshow (mix of panoramas and video) and got the same problem as others: on PC video scene runs with autoplay, but on mobile it's necessary to touch screen for start playing.
So it required to remove phone from headset to start video and insert again.
In my opinion for mobile it's necessary to have "skin_video_playpause" button in WebVR interface. Is it possible? Is anybody work on this issue?
