4K h.264 video streaming fails with nvgstplayer

I have created a 4K resolution h.264 stream of my screen on a PC with OBS. I wish to view it over a closed network on the AGX using nvgstplayer. When I run the nvgstplayer, I get a warning message that I have an undefined packet type. This stream opens and plays on the PC’s local IP address with VLC (which will not play on the AGX). Can I create the correct packet type with OBS to resolve my problem?

I found a fix to make VLC work on the AGX in another forum. VLC not working on L4T R27.0.1? - #15 by megardd
I am happy with this solution and not having to find out how/why nvgstplayer is having problems.
