Last week I installed OBS Studio, Elgato Camera Hub, Itunes - all to my new computer (Acer Nitro) and Epoccam to my iphone and successfully streamed on twitch with both my iphone and my laptop webcam. Today I tried to stream and OBS would not recognize the Elgato camera hub/iphone camera. I tried with the preview on in Elgato Camera Hub and with it off. Did I skip a step this week? How do I get OBS to recognize my iphone through Elgato as a video source?
