usb cam not working

[pascal2313]

i am using the firs jetson nano with a cheap usb cam. and i know it works becouse if i run this command it works
gst-launch-1.0 v4l2src device=/dev/video0 ! image/jpeg, width=1280, height=720! jpegdec ! videoconvert ! ximagesink

it is slow but that does not matter i think
