Pic Zero using NVR feeds on MK3

I am currently using a Rapberry Pi B 3+. I’ve decided to use my Blue Iris NVR to serve my camera footage. If I switch to the Octoprint to just receiving the feed, instead of it serving and receiving the feed, would it perform well enough to work around the noted performance issues?

I'd like to do the same. Blue iris hosts the webcam in this case a logitech c920. I would like to point the octoprint stream URL to the blueiris IP:port to display the BI stream through octoprint.

Has anyone done this, if so how? I think I'm running into the issue of the blue iris server requires a login and I dont see how to set that up with the octoprint stream interface.

Any help appreciated
