Setting up a second camera

What is the problem?

Trying to get a second camera working on my octopi

What did you already try to solve it?

Followed this Setting up multiple webcams in OctoPi the right way and tried looking at some of the solutions in there but couldnt get the 8081 port to send an image

Have you tried running in safe mode?


This is the webcamd.log

  • It seems that you don't have VL805 (Raspberry Pi 4).
    There should be no problems with USB (a.k.a. select() timeout)

Anything im missing information wise please let me know

You have a typo in your configuration. Where you have

usb options: -r 640x480 -f 10 -d /dev/v41/by-id/usb-GenesysLogic_Technology_Co.__Ltd._USB2.0_UVC_PC_Camera-video-index0

Instead of /dev/v41, with a number one, the path starts /dev/v4l with a lowercase letter L.

you solved it straight away thanks buddy, strange though as i just copied and pasted directly from the guide, oh well thanks again
