The newly released Microsoft Media Platform Content Manager pulls together an end-to-end video workflow that allows you to create live streaming events, transcode on-demand content, manage and publish video, edit video, and insert mid-roll advertisements. This open-source release can be used by enterprises, educational institutions, and broadcasting companies to manage their video assets using a lightweight and highly-customizable solution built on Microsoft SharePoint 2010 and Microsoft Media Platform (MMP) technologies, including Silverlight 4, IIS Media Services 4.0, and Expression Encoder 4.
The MMP Content Manager is one of four MMP frameworks optimized around IIS Smooth Streaming and its open-specification adaptive streaming file format, known as PIFF (the Protected Interoperable File Format, adopted by the likes of Ultraviolet and Netflix). It greatly simplifies the workflow for complex video streaming events, such as PDC 2010 and the types shown on the IIS Media Case Studies page.
