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.

What is claimed is: 
     
         1 . A computer-implemented method comprising:
 receiving, at a server device, a plurality of live video streams from a plurality of participant devices;   detecting, from a first participant device of the plurality of participant devices, a user interaction comprising a selection of a graphical live broadcast element within a digital preparation room interface that provides a combined live video stream to the plurality of participant devices and is displayed on the first participant device, wherein the combined live video stream comprises the plurality of live video streams;   based on detecting the selection of the graphical live broadcast element displayed within the digital preparation room interface, converting the digital preparation room interface provided to the plurality of participant devices into a public combined live video stream interface comprising the combined live video stream;   detecting that the combined live video stream is ended; and   based on detecting that the combined live video stream is ended, providing a resume live video stream option for the first participant device to resume the combined live video stream that upon selection resumes the combined live video stream.   
     
     
         2 . The computer-implemented method of  claim 1 , further comprising:
 receiving a selection of the resume live video stream option from the first participant device; and   based on receiving the selection of the resume live video stream option, resuming the ended combined live video stream and the public combined live video stream interface.
