WARNING: erroneous pipeline: no element "v4l2src"

I have a realsense D435 that I want to use in deeesptream

INFO: <bus_callback:204>: incorrect camera parameters provided, please provide supported resolution and frame rate

I searched for information and the following methods can solve it

gst-launch-1.0 v4l2src device=/dev/video4 ! 'video/x-raw, format=YUY2, width=640, height=480, framerate=30/1'  ! nvvideoconvert ! 'video/x-raw(memory:NVMM),format=NV12' ! mux.sink_0  nvstreammux name=mux width=1280 height=720 batch-size=1  ! fakesink

WARNING: erroneous pipeline: no element “v4l2src”

Please clean gstreamer cache and try again. The plugin should be present by default. If it is still present after cleaning the cache, would suggest re-flash the system image. The latest version is Jetpack 5.1.2.

The camera-v4l2-dev-node of [source0] is not configured correctly.
I have already solved the problem.
Thank you.
