Bring up the camera (/dev/video0) with 1280x720 by Gstreamer pipeline:

$ DISPLAY=:0 gst-launch-1.0 nvv4l2camerasrc device=/dev/video0 ! \
"video/x-raw(memory:NVMM), format=UYVY, width=1280, height=720" ! \
nvvidconv ! xvimagesink 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
```
If you cannot see the devices, you should check if the drivers have been probed.

Occur Error: Could not get EGL display connection

If you occurred the errors nvbufsurftransform: Could not get EGL display connection by rununing the Gstreamer command, you can modify the parameter DISPLAY by the command:

# Check and Set environment parameter for 'DISPLAY'
$ export DISPLAY=$(w| tr -s ' '| cut -d ' ' -f 3 | grep :)

# Run Gstreamer pipeline
$ gst-launch-1.0 v4l2src device=/dev/video0 ! \
"video/x-raw, format=UYVY, width=1280, height=720" ! xvimagesink sync=false
