Logitech MX Brio 4K Webcam Not Working with nvgstcapture-1.0 on Jetson Nano

evandrapkl · March 4, 2025, 6:06am

Hi everyone,

I’m having trouble using my Logitech MX Brio 4K webcam on my Jetson Nano. I’ve connected the webcam and checked ls /dev/video*, which returns the following output:

(base) njetson001@njetson001:~$ ls /dev/video0 
/dev/video0

However, when I try running nvgstcapture-1.0, I get the following error/timeout message:

I’ve tried different commands, including specifying --cap-dev-node=0 and adjusting resolution settings, but nothing seems to work. Does anyone know if there are specific drivers or configurations needed to get this webcam running with GStreamer on Jetson Nano?

This is output when using online webcam tester (https://webcamtests.com/), the camera is detected but cannot running properly
“Apparently, your webcam is being used or blocked by another application. To start your webcam, you must temporarily close that application.”

Any help would be greatly appreciated!

Confirm by v4l2-ctl first then try the v4l2src. You should able to find the example for gst-launch-1.0 command line in forum topic.

v4l2-ctl --list-formats-ext
v4l2-ctl --stream-mmap
gst-launch-1.0 v4l2src ......

Try below command.

v4l2-ctl --set-fmt-video=width=640,height=480,pixelformat=YUYV --set-ctrl bypass_mode=0 --stream-mmap

unknown control 'bypass_mode'

What’s wrong?

Remove the bypass_mode from the pipeline for USB camera.

still error, i think i’ve tried that command before

If v4l2-ctl can’t capture successfully that tell it could be sensor HW problem.
You may confirm on host PC to confirm it.
