Nvbuf_utils: Could not get EGL display connection

June 6 - Hello there, I’m working with Jetson Xavier NX, and I want to obtain the video flow from camera. Some errors showed below always appear when I execute my code. However, these errors cannot affect the results materially. Please give me some help to eliminate these errors or warnings.

Please share which release version you use. And do you use Xavier NX developer kit and connect to a TV? Seems like you don’t connect to a TV or display device.
