Many thanks for having a look, but it didn't solve the issue.
I think I may just proceed with my idea of running mediamtx on a separate server and accessing the stream URLs from the relevant MyDesigner 6 component.
I also want to explore doing some more bespoke things with the feeds.
An example of what I want to achieve (which I suspect I can't do via the MyServer and drivers) is to use FFMPEG to combine all four of my CCTV feeds into a grid and output that as a single video feed. I noticed the remote really struggling to display four simultaneous feeds so I want to put the hard work on the server and make it easier on the remote. Suspect I can't do that easily (or at all) via the built in drivers.
Current idea is that when a MediaMTX URL is accessed it triggers FFMPEG to combine the four feeds and MediaMTX serves them up as a single combined video. I think that will be much easier on the remote. I need the trigger in place as I obviously want to avoid a lot of system resources otherwise being used up combining video sources that are not being viewed.
I'll let you know how I get on. It doesn't fix the issue with being unable to configure the driver locally, but I can see that the idea of combining video feeds may be worth the additional effort.
