This is my first post as a new member of the community. I'm looking for some advice on what to try next.
I have an Ender 3 with a Raspberry Pi running Octoprint, and both work fine.
I recently got one of the chinese made endoscope cameras that have USB plugs. When I tried it on my phone (Samsung S6) it gave a great picture so I fitted it to the front of the fan enclosure on the printer.
I edited the "octopi.txt" file and set the following:
camera_usb_options="r- 1920x1080 -f 15"
After a reboot I get the stream as shown in the attached picture (very grainy). I've tried lots of different settings and the size of the picture does change, but it's always grainy.
Does anyone have any idea how to fix this ?
Thanks in advance,
