Hi,
If your source is a v4l2 source, please follow steps in


and see if you can launch it successfully.

Hi,
Please try

gst-launch-1.0 v4l2src device=/dev/video0 ! video/x-raw,format=UYVY,width=480,height=264,framerate=15/1 ! nvvidconv ! 'video/x-raw(memory:NVMM),format=NV12' ! nvoverlaysink

If you run the command and cannot see preview, it is more like an issue in the source. You would need to check the sensor driver first.

Hi DaneLLL

I can capture the video image after change the sensor driver
thanks for your help
