Input Media Properties Object
[The feature associated with this page, Windows Media Format 11 SDK, is a legacy feature. It has been superseded by Source Reader and Sink Writer. Source Reader and Sink Writer have been optimized for Windows 10 and Windows 11. Microsoft strongly recommends that new code use Source Reader and Sink Writer instead of Windows Media Format 11 SDK, when possible. Microsoft suggests that existing code that uses the legacy APIs be rewritten to use the new APIs if possible.]
An input media properties object created by the writer object supports the following interfaces. These interfaces are accessed by a call to QueryInterface on one of the interfaces of the writer object.
| Interface | Description |
|---|---|
| IWMInputMediaProps | Retrieves the properties of an input stream. |
| IWMMediaProps | Used as the base interface for the other media-property interfaces (input, output, and video). |
| IWMVideoMediaProps | Manages the properties of a video stream. This is an optional interface, available only for video streams. |
