thanks, that's interesting, where did you find this fix documented?
Like this?

That definitely made the difference in my frigate config file. Hope it helps.
(I notice in the screengrab you wrote #backchannel=0S... not sure if that was just a typo before you screengrabbed but it's just #backchannel=0 (no S) on the end of the two stream profile bits.)
 
Yup, here it is, once I put this in, the BI can no longer see/connect to the camera, just give me a No Signal RTSP: 404 not found

In my previous screen capture I had pasted it on there (with typo) just to ask the question, I never tried to use like that.
