Abstract
A computer system receives two publishing streams from two multimedia recording devices for generating a playlist for streaming a live event. An ingest endpoint transcodes the publishing stream input into multimedia segments and uploads the multimedia segments to a data storage service. The multimedia segments from both publishing streams are evaluated to determine whether a failover event occurred that requires failing-over from a first publishing stream to a second publishing stream in order to generate the playlist. A playlist is generated, based on the evaluated multimedia segments, and includes Uniform Resource Identifiers for each multimedia segment of the live event. By using dynamic, on-demand playlist generation for input received on two publishing streams, the system is able to provide failover capabilities from a first stream to a second stream without the need for customer or viewer action.
