I just installed the Blue Iris demo and pointed it at my camera via rtsp:/. The camera shows up in the Blue Iris UI, but the frame rate appears to be like one frame every 10 seconds. I have tried fiddling with the frame rate option in the camera configuration but it doesn't appear to resolve the issue. If I connect to my camera via VLC or an ONVIF app on my phone I get a framerate of about 35fps. The stream is H265. The camera is on a wired network with the computer running Blue Iris and the computer running it is a pretty beefy machine (way more powerful than my phone that can render at full framerate!)
This must be a configuration issue, but after spending some time poking around trying to figure out what I have given up.
