Pi 4 w/ pi camera - can't find any webcams

#1

Hey all, new install on a pi 4 with the onboard v2 pi cam, but when I try to run edge-impulse-linux, it errors out because it can’t find any webcams.

I don’t have the option in raspi-config to enable one; the cam seems to be enabled by default now. I am able to trigger the sample image, so it doesn’t appear to be an issue with wiring. I’ve tried updating, but that didn’t work. Editing the dtoverlay didn’t seem to get me anywhere (Cannot detect camera when using raspberry pi 4 - #11 by SoloGithu). I think I’ve reached the end of things to try that have been mentioned in the forums and am not sure where to go from here. Any ideas on what to try next?

Hello @magicofray,

Which OS version are you using?

Best,

I’m on Debian GNU/Linux 12 (bookworm).

did you manage to solve it?

Unfortunately no. Still stuck. My next step was going to be a fresh install of a different build to see if that gets me anywhere. Having the same issue?

Hi @magicofray @AymanBakleh

We have not published bookwork camera support yet, or identified the steps required for users encountering problems with support, when we do I will update the FAQ / troubleshooting.

For now our documentation stil recommends:
Raspberry Pi OS - Bullseye release

Hi Eion, is there an updated edge-impulse-linux CLI tool that works with RPi camera on bookworm OS release?

Thanks!

Can you install the gstreamer1.0-libcamera package and use the latest edge-impulse-linux >=v1.9.2 and let me know if this resolves the issue.

Note that once gstreamer1.0-libcamera is installed it hides v4l2deviceproviders, as a result it hides webcams etc… (Source)
At the moment we’re working on a better.
