Jetson nano cannot open the camera

Hi all~
I use jetson nano and webcam c270, when i type
‘ls /dev/video0*’
in the terminal, it replis
however, when i type
it replis
Segmentation fault (core dumped)’.
i can detect the camera but i cannot open it.
If someone else have any good idea about this situation , let us know.
Thanks, in advance.

thank you so much for your reply, i tried the command
gst-launch-1.0 v4l2src device="/dev/video0" name=e ! 'video/x-raw, width=640, height=480' ! videoconvert ! 'video/x-raw, width=640, height=480, format=(string)YUY2' ! xvimagesink.
But the reply is
‘ERROR: from element /GstPipeline:pipeline0/GstV4l2Src:e: Device ‘/dev/video0’ is busy’
