Nobody can stream 2x 4K to my Apple VR headset. I can barely get a single 4K stream to my TV!
- fwip 2y agoIf you mean you're trying to send the entire viewport, you simply can't stream that over the Internet, even at lower relations. Not for bandwidth reasons, but for latency reasons. A 20ms delay (RTT) between your head moving and the camera moving is a one-way ticket to hurl city. If you did not mean that, please reread my original comment again.
- fwip 2y agoEdit for clarity: A total latency of 20ms from motion->display update is not egregiously bad. But by RTT, I mean the additional latency induced by going to a central server over the internet and back. You've also got latency from input->sensor, sensor->packet, [packet-flight-time], frame-gen-time, [response-packet-flight-time], response-packet->decoded-video, and signal->display-update. You simply should not put the video feed any further away from your headset than a computer on your desk. Even then, a wired connection gives much better results, because the experience is consistently timed.
