This disclosure relates to a system for transcoding a media stream. The system comprises at least one network interface; at least one memory; and at least one processor each coupled to one or more of the at least one network interface and one or more of the at least one memory, the at least one processor configured to publish, via a messaging bus, a segment transcode request in a segment transcode request queue, retrieve the segment transcode request by a transcode worker thread, wherein the first transcode worker thread monitors the segment transcode request queue, transcode by a second transcode worker thread a segment referenced by the segment transcode request, determine by the manifest processor whether the second transcode worker thread has completed transcoding the segment and is still operating, and, if not, transcode the segment by a third transcode worker thread, and store the transcoded segment.
