I'm not sure if this would help anyone but this is how i got rtsp working on octopi after installing the new image with the new camera stack
sudo systemctl edit camera-streamer-libcamera --full
--rtsp-port=8554 \
${OPTIONS}"
sudo systemctl daemon-reload
systemctl restart camera-streamer-libcamera.service
now i can see my prints in frigate
You can add this to the config files in /boot/camera-streamer/* for your cameras, in the OPTIONS section. Then you don't have to edit the service files, the config files provided are meant to be able to add these options.
/boot/camera-streamer/*
Ohhhh! i see! i saw those ${options} in the service file but wasn't sure where i could edit those. thanks charlie!
