Function
OSMF simplifies the development of media players by allowing developers to assemble components to create high quality, full-featured playback experiences.
OSMF is designed for content publishers, developers, and Adobe® Flash® Platform ecosystem partners—anyone who is incorporating video on their website. OSMF decreases time to initial deployment with out-of-the-box support for multiple media types, including video, audio, images, and SWF files.
OSMF simplifies the development of media players by allowing developers to use plug-ins created by partners in the Adobe Flash Platform ecosystem. The extensible plug-in architecture enables additional features from third-party services, such as advertising insertion, rendering, tracking, and reporting for analytics, and content delivery network (CDN) authentication. This allows media player developers to assemble, rather than code, new player functionality.
OSMF supports RTMP and HTTP streaming, progressive download, sequential and parallel compositions of video and other media, and layout in and outside the video player.
