εὕρηκα! I found a way to get a live stream in Bullseye:
Run this on the Pi:
libcamera-vid -t 0 --inline --listen -o tcp://192.168.xxx.xxx:5555 -n
and open a network stream in VLC at:
tcp/h264://192.168.xxx.xxx:5555
Instant live video.
And it only took a month of trawling the internet. (That’s sarcasm.)
Now I’m ready for the onslaught of electoral campaign door-knockers later this year.
