Hi!
I am a newbie to the world of Home Assistant and Node-RED but I am trying to find my way 
Currently, I have a Ring Doorbell that I have been able to view in my Home Assistant Dashboard using ring-mqtt integration. The RTSP stream that is created by the ring-mqtt integration is working fine when using in a player like VLC.
I then started to setup a Node-RED dashboard that I would like to show on my wall mounted tablet using Fully Kiosk. My goal is to show a full-screen “popup” showing the live stream of the Ring doorbell when somebody is ringing it. Then after 60 secs or so, the popup should be closed again.
Can anyone help me by describing the high level steps that need to be taken to convert the RTSP stream to a format that can be used in a Node-RED template node?
Many thanks in advance!
