What is the problem?
Getting a USB webcam to work with Octopi (that only outputs YU12).
How to change mjpg-streamer to a fork?
What did you already try to solve it?
I've edited /boot/octopi.txt and made the below changes. I've also tried with/without the framerate flag, and with/without the -y flag.
camera_usb_options="-r 640x480 -y"
camera_http_webroot="./www-octopi"
camera_http_options="-n"
From research in:
I've found out and confirmed that the webcam that I have outputs a YU12, which is not supported by mjpg-streamer.

Some hope and where I'd like help
I've found some forks of mjpg-streamer that do support YU12. So;
Where I'd like some help is how to change the mjpg-streamer to a different forked version (linked).
I think I'm comfortable downloading the repo from github and building it within the $HOME directory following these instructions. Would it be as simple as that? I'm not sure what are the octopi specific parts or config are vs what comes with the mjpg_streamer.
Have you tried running in safe mode?
Nope
Did running in safe mode solve the problem?
