How can I get the medata from my gst command

Hi all

I'm using gmsl camera with below gst command.

gst-launch-1.0 v4l2src device=/dev/video0 ! "video/x-raw,
format=(string)UYVY, width=(int)1920,height=(int)1080" ! nvvidconv !
"video/x-raw(memory:NVMM), format=(string)I420" ! nvoverlaysink sync=false

I'd like to check frame's kernel timestamp.
When I checked dts and pts after enabling do-timestamp=true, it's not about
kernel timestamp.

So I thought I can get the kernel timestamp from the metadata but I don't
know how to get it.
Is there a way to get kernel timestamp or metadata with my gst command?
