Hello…
I just setup my Ubuntu 20.4 with the latest 3.1rc5 yesterday and was copying the settings from my 3.04 version i am running right now and realized, that i dont get a picture in the motion detection part of any of my cams attached.
It showing the grid, i can mark or unmark as needed but all i get picture wise is a little broken media item symbol in upper left corner which appears and disappears with the button for show or hide background.
Thx for any ideas
