Integrate my webcam into octoprint

Hello everyone
here I am looking for my usb webcam on linux
I can see it connecting but I can't see its path
thank you for your help
my webcam is an avercam

Use lsusb from the console.

hello
this is what it does to me
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 001 Device 002: ID 07ca:313a AVerMedia Technologies, Inc. Live Streamer CAM 313
Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub

Excellent. It is being recognized.

Try

sudo apt install v4l-utils
v4l2-ctl --list-devices

this is what it does to me
Live Streamer CAM 313: Live Str (usb-0000:00:14.0-2):
/dev/video0
/dev/video1
/dev/media0
sorry I'm trying to understand at the same time

Your camera is showing up as a Linux device called /dev/video0 or /dev/video1.

I believe there is also a usb stream called /dev/media0.

Using that you can tell the streamer program how to effectively talk to the camera.

hello I don't know where to put that
thanks again for the explanation

put I'm not on a raspberry pi I'm on a debian

now I can see the webcam clearly on the browser
but I can't see it in octoprint

Hello, I found my webcam which is displayed in the browser but I can't put it in Octoprint, thank you for your help.
