IMFMediaSource interface
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.
Methods
The IMFMediaSource interface has these methods.
| Method | Description |
|---|---|
| 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. |
Remarks
In Windows 8, this interface is extended with IMFMediaSourceEx.
