I am tired by my usb camera loosing stream with octoprint, I have try many settings without a better result (maybe stable for 5 minutes, maybe 30 minutes, but at the end it stop).
So I am giving up, and think to buy a Logitech C920.
Is it a good choice for a peaceful stream ?
Thank you
Updated my raspberry pi4 and now working well !
Don't need to spend money for a new camera 
sudo rpi-update
