Implemented by media source objects.
Media sources are objects that generate media data. For example, the data might come from a video file, a network stream, or a hardware device, such as a camera. Each media source contains one or more streams, and each stream delivers data of one type, such as audio or video.
The IMFMediaSource interface has these methods.
|IMFMediaSource::CreatePresentationDescriptor||Retrieves a copy of the media source's presentation descriptor. Applications use the presentation descriptor to select streams and to get information about the source content.|
|IMFMediaSource::GetCharacteristics||Retrieves the characteristics of the media source.|
|IMFMediaSource::Pause||Pauses all active streams in the media source.|
|IMFMediaSource::Shutdown||Shuts down the media source and releases the resources it is using.|
|IMFMediaSource::Start||Starts, seeks, or restarts the media source by specifying where to start playback.|
|IMFMediaSource::Stop||Stops all active streams in the media source.|
In Windows 8, this interface is extended with IMFMediaSourceEx.
