For more information, see Creating Playback Topologies.Ĭall IMFMediaSession::SetTopology to set the topology on the Media Session. In this step, the application creates a partial topology that does not include the decoders. For more information, see Using the Source Resolver.Ĭreate a topology that connects the media source to the EVR and SAR. Use the source resolver to create a media source. The following is a general outline of the steps needed to play a media file using the Media Session:Ĭall the MFStartup function to initialize the Media Foundation platform.Ĭall MFCreateMediaSession to create a new instance of the Media Session. The following diagram illustrates this process. The Media Session controls the data flow and sends status events to the application.A topology defines the flow of data from the media source to the EVR and SAR.The Streaming Audio Renderer (SAR) renders audio to a speaker or other audio output device.The Enhanced Video Renderer (EVR) renders video to the screen.The Source Resolver creates a media source from a URL.Decoders convert encoded media data into uncompressed video and audio. The media source creates stream objects for each audio or video stream in the file. A media source is an object that parses a media file or other source of media data.The following objects are used to play a media file with the Media Session: For information about DRM in Microsoft Media Foundation, see How to Play Protected Media Files. This topic does not describe how to play files that are protected by digital rights management (DRM).
