Setting up Open Broadcaster

Even though the ATEM Mini Pro model can stream directly using its Ethernet connection, if you
want to stream using an external computer then you can connect the USB-C and it will appear
as a webcam on your computer. This then lets you use streaming software such as Open
Broadcaster for streaming.
This section shows how to use Open Broadcaster to stream via the USB-C webcam output.
Open Broadcaster is an open source application that works as a streaming platform between
your ATEM Mini and your favorite streaming software like YouTube, Twitch, Facebook Live,
Vimeo Live and others. Open Broadcaster compresses your video to a bit rate that is easily
managed by your streaming app.
Below is a demonstration of how to set up Open Broadcaster to stream the webcam output
from your ATEM Mini using YouTube as the streaming application.
