sample program

The NVIDIA Jetson family is the one that powers the Nintendo Switch, although the AGX Xavier is of a more modern vintage (turing, 512 cores.)

When using the sample program from https://watte.net/opengl-fails.zip together with libsdl2 2.0.8 built from source on the Xavier, software works great. However, the opengl renderer just renders a black window.

The sample program captures a side-by-side stereo video image from a Zed camera; you can change the frame size to match some other webcam you might have; you can also change the yuyv->rgba conversion function to force a particular color, but it will still just render black.

I don't have that platform to test on, did you figure this out?
