Raspberry Pi 4 Logitech C922 error

Tsmyth · November 26, 2021, 5:23pm

Hi, i am new to this forum and to raspberry pi’s, I am having a problem with using the command edge-impulse-linux, when I use this command this error appears,

Failed to initialize linux tool Error: Cannot find any webcams, run this command with --disable-camera to skip selection 
at /usr/lib/node_modules/edge-impulse-linux/build/cli/linux/linux.js:423:23
at processTicksAndRejections (internal/process/task_queues.js:97:5)

The raspberry pi is picking up the webcam as when I use lsusb,

Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 001 Device 003: ID 046d:085c Logitech, Inc. C922 Pro Stream Webcam
Bus 001 Device 002: ID 2109:3431 VIA Labs, Inc. Hub
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

And when I use OpenCV with cv2 with this test program I get a video stream,

import cv2
import time

cam = cv2.VideoCapture(0)
cam.set(3,320)
cam.set(4,240)

while True:
	time.sleep(0.1)
	ret, image = cam.read()
	cv2.imshow('Imagetest',image)
	k = cv2.waitKey(1)
	if k != -1:
		break
cam.release()
cv2.destroyAllWindows()

Any help would be appreciated
Thanks

Hi @Tsmyth,

Could you try the patch below and let us know if it works?

Hi i had already tried this with no luck, but tried it again anyways with no luck, i have noticed when running gst-device-monitor-1.0 my webcam comes up as caps : audio/x-raw which has confused me

Hi, we’re investigating this issue. There’s a change in how gstreamer video sources work in Bullseye, and trying to pin down exactly what we need to fix on our end.

Hi, we’ve pushed v1.3.0 of the Edge Impulse for Linux tools which fixes this issue. You can update via:

sudo npm update -g edge-impulse-linux

Perfect I think it is working thanks
