Hi,
I am trying to use a Black Magic UltraStudio Mini device to capture video to OBS. When I first ran it everything worked great. But then randomly it stopped. I can get the device to work with Black Magic Media Express no problem. Even the Black Magic Utility shows the input is working when I am running OBS but the log still says "Failed to enable video input". I downloaded Wirecast trial and it works fine in that software.
The frame rate, resolution match perfectly. I can get the device to work with my AppleTV in OBS by unplugging the thunderbolt out then in.
