Epiphan AV.io HD - Grab and Go USB Video Capture for VGA, DVI, and HDMI up to 1080p at 60 fps

Can I capture video to a Raspberry Pi with this?

Does it record gameplay from consoles like Avermedia or Elgato devices ?

Could I use more than one at a time? I'd like to capture two sources and live stream them together split screen

Will this work with a chromebook that only accepts android usb connections?
