Use the GStreamer pipeline to verify a 1280x720 resolution camera (/dev/video0) without opening a display window:

$ gst-launch-1.0 nvv4l2camerasrc device=/dev/video0 num-buffers=30 ! \
"video/x-raw(memory:NVMM), format=UYVY, width=1280, height=720, framerate=60/1" ! \
nvvidconv ! "video/x-raw(memory:NVMM), format=NV12" ! fakesink sync=false

Use the GStreamer pipeline to launch a 1280x720 resolution camera (/dev/video0) via the GPU on the Jetson display:

$ DISPLAY=:0 gst-launch-1.0 nvv4l2camerasrc device=/dev/video0 ! \
"video/x-raw(memory:NVMM), format=UYVY, width=1280, height=720, framerate=60/1" ! \
nvvidconv ! "video/x-raw(memory:NVMM), format=NV12" ! nv3dsink sync=false

Troubleshooting

Cannot Find Cameras

If you cannot bring up the cameras, you can check if the video device does exist.

$ ls /dev/video*  # List all video devices
/dev/video0  /dev/video1  /dev/video2  /dev/video3
/dev/video4  /dev/video5  /dev/video6  /dev/video7

If you cannot see the devices, you should check if the drivers have been probed.

$ lsmod | grep -E 'tevs|max96724|max96717'
max96717               32768  8
max96724               36864  0
tevs                   32768  0

You can also check whether the VLS-GM2 boot entry is active after reboot.

$ grep -nE 'DEFAULT|LABEL|FDT|OVERLAYS' /boot/extlinux/extlinux.conf
DEFAULT tn-vls-gm2
LABEL tn-vls-gm2
      FDT /boot/tegra234-p3768-0000+p3767-0005-nv.dtb
      OVERLAYS /boot/tegra234-p3767-camera-p3768-vls-gm2.dtbo

Occur Error: Could not get EGL display connection or Failed to start nv3dsink

If you encounter nvbufsurftransform: Could not get EGL display connection or nv3dsink: Failed to start by running the GStreamer command through SSH, run the command from the Jetson graphical session or set the display environment before launching the pipeline:

$ export DISPLAY=:0
$ export XDG_RUNTIME_DIR=/run/user/$(id -u)
$ gst-launch-1.0 nvv4l2camerasrc device=/dev/video0 ! \
"video/x-raw(memory:NVMM), format=UYVY, width=1280, height=720, framerate=60/1" ! \
nvvidconv ! "video/x-raw(memory:NVMM), format=NV12" ! nv3dsink sync=false

If the display sink still cannot start from SSH, verify the camera capture path without opening a display window:

$ gst-launch-1.0 nvv4l2camerasrc device=/dev/video0 num-buffers=30 ! \
"video/x-raw(memory:NVMM), format=UYVY, width=1280, height=720, framerate=60/1" ! \
nvvidconv ! "video/x-raw(memory:NVMM), format=NV12" ! fakesink sync=false
