I display YouTube live streams in VLC 24/7, they've been going fine for weeks - then suddenly, this afternoon = black screens with traffic cone and "VLC is unable to open the MRL https.etc etc".
I have tested with YT streams which I know are live and working, none work - tested a non-YT live stream, that's fine.
Has YouTube introduced a new "rule" out of the blue that VLC needs updating to cope with?
