livePreview transmits a motionJpeg stream over TCP/IP using Wi-Fi, mobile data or Ethernet. It is used to preview the image prior to taking a picture. Some developers use livePreview to stream the video from the camera to different devices.
This is primarily for experimentation. Streaming over wi-fi in 5.8K using livePreview is generating more heat in my tests and the camera suffered thermal shutdown in extended use. I did not use a fan. I recommend people use the USB cable with the THETA X for live streaming. However, as the API supports 5.7K wifi streaming direct from the camera, let’s test it out!
This update to the webAPI documentation indicates that the THETA X can show previewFormat in different resolutions, including 5.8K.

check format
testing 5760x2880 frames
confirming that frame is 5760x2880
frames look good.
testing 512x512 frames at 30fps
To reduce heat
{
"name": "camera.setOptions",
"parameters": {"options": {"previewFormat": {"width": 512, "height": 512, "framerate": 30}}
}}
frame looks a bit distorted
