As you probably know, Apple is not just badly supported in the surveillance industry, it is actively hated.
As I was working on the ONVIF stuff, I encountered this quite often. As soon as people found out I was working on Apple stuff, the relationship would go belly-up.
I ended up not bothering to renew my ONVIF membership, because it didn’t really buy me anything.
I created a “breadboard” streaming server for ffmpeg[0], but I’ve put my ONVIF stuff aside for a while, as I work on Bluetooth projects.
There is even a nice sample application that you can try out without having to write any code.
