Blackmagic Design released a new ATEM Mini production switcher that has many good features for streaming live to an online platform. It has 4 HDMI inputs for cameras, consoles, or anything else HDMI and has a built in USB output. The USB output means that if you connect it to a computer it appears as a 1080p webcam that can be used for any streaming platform. The price is very low compared to other offerings at only $295 for example the Roland VR1-HD has many of the same features but it has one less HDMI input and it is $1495.
