Using a YUY2 camera and trying to convert to BGR using a pipeline I have tested for other format conversions and it works just fine. For this example it fails.
gst-launch-1.0 -v v4l2src device="/dev/video$CAMERA_NAME" ! 'video/x-raw, width=(int)1920, height=(int)1080, format=(string)YUY2 , framerate=60/1' ! videorate ! 'video/x-raw, framerate=(fraction)20/1' ! nvvidconv ! 'video/x-raw, format=(string)BGRx' ! videoconvert ! 'video/x-raw, format=(string)BGR' ! queue ! shmsink wait-for-connection=0 socket-path="/tmp/cam$SHARED_MEM_ID" shm-size=200000000 sync=false
If I leave out the nvvidconv part it works but there is lag as the conversion is not using the hardware support. It is unclear to me why the YUY2 to BGRx part is failing as the conversion seems to be supported in the docs by nvvidconv.
My NX Jetpack is as follows:

gstreamer version is:
