Spherical 360 view for live feed as a virtual camera?

Is the RTSP plug-in latency around 350ms? You can take a video of a stopwatch on your computer monitor with the THETA Z1 like this:

Even if you use a USB cable, you will not be able to lower the latency beyond that as the camera needs to stitch the two spheres into equirectangular.

Thanks for sharing your solution.
