COORDINATION OF VIDEO STREAM TIMING IN CLOUD-BASED VIDEO STREAMING SYSTEM

摘要

A method to coordinate video stream timing is disclosed. In one embodiment, a request is received at a streaming platform coordinator (SPC) to create a plurality of synchronized media workflows for video sources. Using the plurality of video sources as input, the SPC transmits a request from the SPC to at least one video streaming platform to create the plurality of media workflows, which are assigned to a plurality of workers. The SPC causes the plurality of videos to be routed to the plurality of workers upon receiving the request to route them. The SPC then determines a set of timing offsets to synchronize the plurality of media workflows, and makes the set of timing offsets available to the plurality of workers so that the workers publish synchronized media outputs. A system to perform the method and a storage medium storing instructions to perform the method are disclosed too.

1. A method executed by an electronic device implementing a streaming platform coordinator (SPC) to coordinate processing of a plurality of video sources, originated from a plurality of video output devices to broadcast an event concurrently, the method comprising:
receiving a request to create a plurality of media workflows for the plurality of video sources, wherein the plurality of media workflows are to be synchronized; responsive to receiving the request at the SPC to create the plurality of media workflows, transmitting a request from the SPC to at least one video streaming platform to create the plurality of media workflows using the plurality of video sources as input, wherein the plurality of media workflows are assigned to a plurality of workers; receiving requests from the at least one video streaming platform to route the plurality of video sources to the plurality of workers; causing the plurality of video sources to be routed to the plurality of workers; determining a set of timing offsets to synchronize the plurality of media workflows; and making the set of timing offsets available to the plurality of workers, wherein the plurality of workers apply the set of timing offsets so that output of the plurality of media workflows are synchronized.
