Beginner problem: usb camera not detected

Hello, I can’t get my usb webcam to work on jeston nano. It is detectable, it can be found in /dev/video0 but does not work with applications like cheese or even VPI Demos V1.0. Do you have any idea why?

Cheese never works for me.

Look at gst-launch-1.0

gst-launch-1.0 v4l2src device=/dev/video0 ! xvimagesink

or for mjpeg device

gst-launch-1.0 -v v4l2src device=/dev/video0 ! image/jpeg, width=1920, height=1080, framerate=30/1, format=MJPG ! jpegdec ! xvimagesink

if you want the audio start a loopback for pulseaudio

pactl load-module module-loopback

Thank you very much. Gstreamer works fine !
