How does HTTP Dynamic Streaming work within OSMF and Flash Player 10.1?

Media playback is started by requesting and parsing a manifest file (FMF). The manifest file contains four main parts: • The bootstrap information — describing the make up of the file format, allowing OSMF to form URLs to start requesting the media • The DRM license server location — which OSMF can use to prefetch a license file from the Flash Access license server • The metadata of the stream • The bitrates associated with the stream — so OSMF can switch between bitrates OSMF will use the information from the manifest file to generate the URLs and begin filling a buffer using new APIs inside Flash Player 10.1. OSMF will also fetch any required DRM keys and use them for playback, also using new APIs in Flash Player 10.1. During playback, OSMF is responsible for managing fragment requests, monitoring QoS, and switching bitrates if needed.
