is designed to make live adaptive bitrate delivery over HTTP easy. The Transcoder can ingest a single high bitrate live stream and create multiple lower-bitrate renditions on the fly, which are keyframe-aligned for adaptive bitrate delivery. Synchronized Multimedia Integration Language (SMIL) files enable you to group the high bitrate stream and the new renditions together in logical groups for live adaptive bitrate delivery.
This article explains how to use a SMIL file with transcoded or transrated streams created by Wowza Transcoder.
