Unable to get the live video feed

Hello,

My SkyController3 is connected to my PC (Ubuntu 16.04) with a steady blue color (Meaning it is paired with the anafi drone). I have successfully followed the installation guide but when I launch the command ./out/pdraw-linux/staging/native-wrapper.sh pdraw -u rtsp://192.168.53.1/live from the installation directory, I get PDraw with a black screen.

Any idea on what might go wrong please?
