This quite interesting, I've been toying with building a capture box myself for presentation/gaming streaming and recording. It takes two inputs: HDMI-in from monitor, and HDMI/Other Digital for the camera, and one output: HDMI out back to the monitor. It can be configured to record to its internal SSD or stream (to popular streaming sources). I run a meetup and would love an easy way to record talks, there isn't much out on the market currently which is unfortunate. I'm really happy to see stuff like this surface in the OSS world.
