This document provides an overview of the Open Source Media Framework (OSMF) presented by David Hassoun of RealEyes Media. It discusses OSMF's goals of providing a single media player, describes its core components like the MediaElement and MediaPlayer, and how traits and metadata are used. It also covers key OSMF concepts like factories for connections and media, and how plugins can extend OSMF's capabilities for things like advertising and captions. Code demos are provided to illustrate OSMF concepts like traits, factories and creating a simple plugin.
