I finally used the Debian version, which is always older, but it works. I'm using a Logitech webcam for the video and microphone, and that's a bitch. You can make the choices inside obs. Here is my final test. The new version of obs has a better filter for the mike, here there is some noise. Also, the lips are out of synch, but that's Linux for you. I'm sure there's some horrible fix out there somewhere.
The whole point is to have a live broadcast when the M7 hits Oklahoma. Then we might get some feedback live.
