WMEncDataView Object

The WMEncDataView object controls data view objects. You can use this interface to configure the display settings of the stream, and start or stop the rendering process.
Currently, you can preview and postview a stream. A preview object displays a specific multimedia stream before it is compressed. A postview object displays the same stream after compression and decompression. Postviews, therefore, more closely resemble the image rendered in Windows Media Player on a client computer.
All of the data view objects associated with a stream are grouped together in a collection. Thus, there can be multiple collections, each associated with a different stream. Collections are managed by the IWMEncDataViewCollection object.
The WMEncDataView object exposes the following methods.
| Method | Description |
| GetViewProperties | Retrieves the properties of a specific input stream. |
| SetViewProperties | Specifies the properties of a specific input stream. |
| StartAllViews | Starts displaying all media streams. |
| StartView | Starts displaying a specific media stream. |
| StopAllViews | Stops displaying all media streams. |
| StopView | Stops displaying a specific media stream. |
