IMSVidVideoRenderer::put_DecimateInput
This topic applies to Windows XP or later.
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
Parameters
bDecimate
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.
Requirements
Header: Dshow.h.
Library: Quartz.dll.
