Live group video streaming

Abstract

The present disclosure relates to systems, non-transitory computer-readable media, and methods for accurately, flexibly, and efficiently broadcasting public combined live video streams from multiple participant devices, which change over the course of the live broadcast, as well as generating dynamic user interfaces that streamline adding, removing, and swapping participant devices from the public combined live video stream. In particular, a live video streaming system facilitates compositing live video streams from multiple participant devices into a public combined live video stream within a digital room before broadcasting the public combined live video stream to viewer devices. In addition, the live video stream smoothly and efficiently transitions new participant devices from a digital waiting room to the public combined live video stream as well as switches current participant devices from the public combined live video stream to a digital waiting room, all while maintaining live video stream of the participant devices.
