The gst-launch-1.0 command with nvarguscamerasrc plugin can works, also can get camera preview, the command is as below:

gst-launch-1.0 \
    nvarguscamerasrc sensor-id=0 \
    ! 'video/x-raw(memory:NVMM), width=1920, height=1080, format=(string)NV12, framerate=(fraction)30/1' \
    ! nvoverlaysink

but it not works with v4l2src plugin ,the command is as blow:

gst-launch-1.0 \
    v4l2src device="/dev/video0" \
    ! video/x-raw, width=1920, height=1080, format=YUY2, framerate=30/1 \

Hi,
The source looks to be a Bayer sensor. Please run

$ v4l2-ctl --list-formats-ext

to get more information. If it does not support YUYV, you are not able to launch it through v4l2src.
