Bernie ordered a Blackmagic ATEM Mini to learn how to do video streaming and switching. But he hasn't gotten it yet. Leo says that it works great as an affordable streaming device. But he has a problem with connecting his webcams because it requires HDMI in. Leo says that he uses DSLRs because they offer clean live HDMI out. Is there an affordable USB to HDMI adapter? Leo says that there's a post on the AVS forums about that here - https://www.avforums.com/threads/connect-webcam-through-hdmi-input.1788260/. From the chatroom -https://www.febon.net/products/usb-uvc-webcam-to-hdmi-adpater. Create an adapter with a Raspberry Pi and Debian. There's an app called Cheese, which is a webcam app that can then be used.
