Oak Viewer for my setup (Headless RPi + OAK-D W (OV9782) USB)

(If this has been answered in the documentation, please just point me there.. I have looked and can't find it…)

Is there a way to run Oak Viewer on my Windows PC and have it connect over ethernet to the OAK-D W camera which is connected to a Raspberry Pi on the same network?

On the Oak Viewer page it says "..the local version includes a device selector in the header that displays all OAK cameras the Viewer can detect, including devices available via Ethernet and USB. " Does this mean that Oak Viewer on my PC can somehow connect to a camera on a RPi on the same network? Is there some agent or program I can run on the RPi that makes that camera accessible to Oak Viewer on my PC?

Or is the only option to run Oak Viewer on the RPi and have it redirect X window output back to my PC?

Or, should I use the Oak Visualizer described here https://docs.luxonis.com/software-v3/depthai/tools/oak-visualizer/ ? As far as I can tell Oak Visualizer does not provide all of the features that Oak Viewer does (specifically the stereo calibration features).

Thank you!

I'm also unable to run depthai-viewer on the RPi, redirecting X window output to the PC (running VcXsrv 1.20.14 on the PC). Here is the message I get from depthai-viewer

Note: you can probably enable DRI3 in your Xorg config

Chatgpt suggests that there isn't a Windows X server that has DRI3 support and concluded:

You can use Oak viewer with devices directly connected to the PC (either USB or network).

When self-hosted agent is out, you might be able to install it on RPI and then use the web-viewer on the PC to connect to it.

Currently there is no workaround.

Thanks,
