Escapi can't see virtual cameras like OBS Virtual Camera

(pic of skype showing all cams. Wow, that pic came out big)

Escapi (using the propgui.exe example) can see my Game Capture HD60 Pro, but it does not see virtual cameras like "Camera (NVIDIA Broadcast" and "OBS Virtual Camera".

I suspect this is an issue with Media Foundation (MFEnumDeviceSources just won't see them) and the only "fix" is to use DirectShow (which we're not supposed to use anymore?!) , but figured I'd better ask in case I'm totally wrong and there actually is a way to access these.
