If you've upgraded a printer host to Debian 13 "Trixie" — or you're running a board like the BTT CB1 on a recent Armbian image — you may find that your Obico webcam feed stops working. The premium (high-FPS) stream never starts, and the logs are not especially forthcoming about why.
The short version: Trixie ships no janus package, and Obico's bundled fallback binaries don't cover Debian 13 either. So you have to build Janus yourself — and there are four separate ways to build it that look successful but leave you with a Janus that Obico can't use.
