With random chinese knock-off and GoPro 3, I had a latency of 10-11 frames when doing 60 fps stream. It was usable for video calls, but I had problems with reliability (old battery in Gopro, and even if it was permanently connected to power source, it charged only when I turned it on -- which usually was when I wanted to have a call).
