Nvidia Broadcast

Hi, is there any reason why Unreal 5.4 can’t ‘see’ Nvidia Broadcast virtual camera in Mediaplayer? It can see NDI and even other virtual cameras like OBS and Animaze and I had it recognizing an DSLR capture through an Elgato card but it can’t see Nvidia Broadcast which is maddening.

I would like to be able to use the background replacement feature in that software and bring it into engine.

Any help greatly appreciated, thanks!
