IMSVidVideoRenderer::put_DecimateInput method (segment.h)
[The feature associated with this page, Microsoft TV Technologies, is a legacy feature. Microsoft strongly recommends that new code does not use this feature.]
The put_DecimateInput method specifies whether the Video Mixing Renderer (VMR) will decimate the video (that is, reduce the native video size) before processing it.
This method is currently not supported.
Syntax
HRESULT put_DecimateInput(
VARIANT_BOOL pDeci
);
Parameters
pDeci
Specifies whether to enable or disable video decimation. Use one of the following values.
| Value | Description |
|---|---|
| VARIANT_TRUE | Enable video decimation. |
| VARIANT_FALSE | Disable video decimation. |
Return value
If the method succeeds, it returns S_OK. If it fails, it returns an error code.
Remarks
This property should be set to true when the native video stream is HDTV but the system monitor is set to a lower resolution. This prevents the VMR from doing unnecessary work by processing the video at high resolution and then shrinking it.
