You can now use Amazon Elastic Transcoder to create MPEG-DASH streams. MPEG-DASH is a standard for HTTP based adaptive bitrate streaming of video. With Elastic Transcoder support for MPEG-DASH, you can now reach a wide range of DASH-compatible devices (from desktop to mobile and OTT) with fewer output renditions created using the same easy workflows that Elastic Transcoder supports for HLS and Smooth Streaming. This enables you to simplify your video processing workflows and helps improve cost efficiency.
