help! gst-launch1.0 can't work on my jetson nano!

Hi all!
I use a csi-camera and when I launch the camera,the system stuck.Then the computer reboot.
I use this script to launch the camera:

gst-launch-1.0 nvarguscamerasrc ! 'video/x-raw(memory:NVMM),width=3820, height=2464, framerate=21/1, format=NV12' ! nvvidconv flip-method=0 ! 'video/x-raw,width=960, height=616' ! nvvidconv ! nvegltransform ! nveglglessink -e

if I use a USB camera,the gst-launch1.0 window is stuck.
I’ look foward to your help!Thank you.

Hi,
Please check if your camera source is good by running:

gst-launch-1.0 nvarguscamerasrc num-buffers=300 ! 'video/x-raw(memory:NVMM),width=3820, height=2464, framerate=21/1, format=NV12' ! fakesink

If above pipeline runs fine, please try

gst-launch-1.0 nvarguscamerasrc num-buffers=300 ! 'video/x-raw(memory:NVMM),width=3820, height=2464, framerate=21/1, format=NV12' ! nvvidconv ! 'video/x-raw(memory:NVMM),width=1920, height=1080' ! nvoverlaysink
