Sococo uses the industry standard WebRTC and tries first to send video over UDP, then automatically switches to TCP when UDP traffic is blocked. That said, TCP is a much less desirable protocol for streaming video because of the overhead incurred for error checking. Applications that stream live video, like Sococo, perform better over UDP because its speed is desirable and the error correction guaranteed by TCP isn't necessary. Unblocking UDP, and confirming proxy and firewall settings, will assure a higher quality and more consistent Sococo user experience.
