Abstract
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.
