Getting vlc to start network stream on boot (if stream is up) and monitor stream status in case it goes down

I've written a script that first checks whether a local network stream is up, then if this is the case it will start vlc. It will then keep monitoring the stream, if it goes down it will close vlc and wait for the stream to return before restarting vlc (see below).

If I run the script manually this works.

I'd like this script to run automatically on startup (using Raspbian). The issue I seem to be having is that regardless of how I get the script to run on startup I see that it's briefly connecting to the network stream but it isn't opening vlc (at least not visibly on the desktop).

Any suggestions gratefully appreciated.
