My own set of commands is almost identical. I just used different layer numbers for each of them. I run 7 cams on a pi 2, however some of them are super small streams while at least one is 1280x720.
Some autostart methods work specifically with the GUI and won't work with a CLI-only installation. Try adding the startup command to rc.local instead.OK finally got around to looking at this. Are you guys running this on the desktop Raspian OS on the pi or the streamlined CLI only OS?
I'm command line only version and can't get it to autostart the web service. Manual load is fine. Still have to configure the cameras.
sudo nano /etc/rc.local
