Jetpack 4.5: USB Camera does not work in Cheese and opencv 4.1

Hi,
Please check the sample:

and run this pipeline:

 v4l2src device=/dev/video0 ! video/x- raw,format=YUY2,width=640,height=480,framerate=30/1 ! videoconvert ! video/x-raw,format=BGR ! appsink

A user has mentioned performance is better with two nvvidconv plugins:

So you may also try

 v4l2src device=/dev/video0 ! video/x- raw,format=YUY2,width=640,height=480,framerate=30/1 ! nvvidconv ! video/x-raw(memory:NVMM),format=BGRx ! nvvidconv ! video/x-raw ! videoconvert ! video/x-raw,format=BGR ! appsink
