Using a no name camera for right now as Webcams are sold out everywhere. I installed Octopi latest version over Rasbian as my Pi is also running PiVPN and Orchid for my cameras. The MJPEG streamer seems to work fine as I can hit the IP:8080/?action=stream in a browser and it works fine. The Snapshot URL Works fine and I can preview the image but for some reason the URL for the webcam stream just won't load in the front end of Octoprint.
I checked for a webcamd.log but there doesn't seem to be one. Probably a quirk of not using the image.
What stream url do you use?
Is an octopi thing.
I've tried a bunch of the same thing essentially. The IP if the pi is 192.168.1.15 static'd.
So I've tried http://192.168.1.15:8080/?action=stream (which is the URL that works in browser) I've also tried localhost and 172.0.0.1 etc. I've tried just the ?action=stream which I think what it auto completes to. When I preview the stream it shows one of those can't display image type of deals windows does. I will upload a pic when. I get back to a PC.
