2. 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 :)
