IMSVidVideoRenderer::get_DecimateInput
This topic applies to Windows XP or later.
The get_DecimateInput method queries whether the Video Mixing Renderer (VMR) is currently configured to decimate the video (that is, reduce the native video size) before processing it.
This method is currently not supported.
Syntax
Parameters
pDeci
[out] Pointer to a variable that receives one of the following values.
| Value | Description |
| VARIANT_TRUE | The VMR is configured to decimate the video. |
| VARIANT_FALSE | The VMR is not configured to decimate the video. |
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.
Requirements
Header: Dshow.h.
Library: Quartz.dll.
