Microsoft Azure Media Services
This document provides an overview of Microsoft Azure Media Services for encoding, packaging and streaming media. It describes Media Services' support for common input/output formats and codecs for video and audio encoding. Tasks define processing instructions for assets containing media files and associated metadata. Jobs coordinate task execution across processors. Streaming can be static via packaged files or dynamic via just-in-time encoding. Pricing is based on data processed and reserved units for parallel tasks or streaming bandwidth.
