They're thinking that presentation cannot be a camera feed, but it can,
because our podium presenter sends HDMI, which goes through a hardware
encoder (blackmagic web presenter), which presents as a UVC camera.

What you could do is plug that encoder into a Raspberry Pi running my software and send the stream to the conference that way.
Ideally whipi would be running in the encoder hardware.
