I have the Tricaster 2 Elite 3RU with 8 SDI inputs and outputs. I would like to use them in something like vMix or OBS, but when I add Camera or Video Capture Device respectively, the inputs do not appear as an option to select. When I open up VizRT or the Tricaster software, the inputs appear normally (as they should).

Does anyone have any suggestions on what I could do to access those in vMix or elsewhere?
