Enabling decoder compatibility model in BI seems to have solved the no signal issue for me, as well. But now I've ran into a new issue that I was not expecting. Within
Blue Iris, the Dahua (EmpireTech) 180 turret is now lagging 1 minute behind my other cameras, and is reporting 13.85 fps. I have the camera set to 25 fps and 12288 kbps (to give it a little headroom). Logging in through the web configurator shows the camera functioning at full frame rate.
BI seems to be really struggling with it right now. It's clearly a Blue Iris issue, not a camera issue. What would be the best way to resolve this issue going forward?
