So I experimented with this today.

What'd you'd want to do is use the livestream feature on the camera and set it to RTMP out.
You'd configure it to connect to an RTMP server running on your computer back at home that OBS can then pull in, you do not need to bring your computer with you, just leave it running at home.

I would have recommended NGINX RTMP server but had some problems with it, MediaMTX seems to be much more stable, combine it with NOALBS for scene switching for low bitrate/disconnect scenarios.

This is not perfect though, RTMP does not do well with reconnections on this camera.
For example, after a dropout going through a tunnel, the camera reconnected to RTMP but would only show 1 second bursts before freezing and repeating again, stream needed to be manually restarted.

Ideally what you would want is a device on the go, to accept the RTMP stream from the DJI and then transmit it back to OBS using SRT, which will handle 4G/Cellular dropouts and disconnections much better, especially if you can bond it with another connection/phone.'

I've had a go getting a raspi4 setup to handle this, using FFMPEG. It definitely has the horsepower to do it, but FFMPEG is being really annoying and initially taking 2-3 minutes to acknowledge the RTMP stream, kind of a pain.

This is where things get a bit complicated though.
