Video feed from HereLink with ethernet connected camera - on Mission Planner on a tethered PC

I’m doing a little work this week with SIYI gimbal/cameras.

I’ve had some success using the ethernet connection to the HereLink air unit - which requires using the custom SIYI HereLInk apps - either their custom version of Qgroundcontrol or the SIYI-FPV app.

Using standard HDMI camera connections to the HereLink, there is no trouble getting video feed to a tethered version of Mission Planner via a wi-fi or USB tether connection.

I haven’t yet figured out how (if possible) to do the same if the camera is using an ethernet connection to HereLink air unit.

When the SIYI gimbal/camera has an ethernet connection to the HereLink air unit, the video feed is available with an RTSP server as the source.

The question is can a copy of a USB or wi-fi tethered Mission Planner gain access to this RTSP video stream?

Note: When using a camera connected via ethernet to the HereLink air unit - you enter the RTSP address for the video feed source in the custom SIYI Qgroundcontrol app. For some reason, the HereLink’s native Qgroundcontrol will not get the video feed from this RTSP address.

So to recap - I’d like to use a camera with an ethernet connection to a HereLink air unit - and get that video feed on a tethered copy of Mission Planner.

I’d appreciate any thoughts our suggestions!
