Jetson nano cannot open the camera

[chentaotao666]

Hi all~
I use jetson nano and webcam c270, when i type
‘ls /dev/video0*’
in the terminal, it replis
‘/dev/video0’.
however, when i type
‘camorama’,
it replis
‘Opening in BLOCKING MODE
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.

Have reference to below link to try gst-launch-1.0 with v4l2src.

Using logitech webcam C510 on Jetson nano with Gstreamer and OpenCV

Hi, I am using a raspberry pi cam on my nano with gstreamer and opencv, for that my init string is: nvarguscamerasrc ! video/x-raw(memory:NVMM), width=(int)1280, height=(int)720, format=(string)NV12, framerate=(fraction)60/1 ! nvvidconv flip-method=0 ! video/x-raw, width=(int)1280, height=(int)720, format=(string)BGRx ! videoconvert ! video/x-raw, format=(string)BGR ! appsink This is working fine for the raspberry pi. Before getting deeper in the details, I would like to know if anybody knows…

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’
