Finally! Safari and SFU became good fellows. eyeson is based on this great aproach of Single-Stream-Technology. All participants are basically merged into one audio/video stream that opens a great window of advantages. This technique is called MCU ("Multipoint Control Unit"). Some time ago, eyeson introduced a new mode called SFU ("Selective Forwarding Unit") to directly send your audio/video stream to your video call participant and vice versa. This mode is only activated when 2 people have a video call.
