I saw a post on G+ were someone used OBS to overlay printer status over a live video of their printer. Since I used a USB camera to monitor the filament in the extruder, I knew I needed this.
I used OBS (https://obsproject.com/) to combine video from two usb cameras, and 4 window captures from Repetier host to provide the printer status boxes.
This can be recorded or streamed to several live streaming services like twitch, or Youtube Live. I use my second monitor output to a TV for easy monitoring.
