IMSVidVideoRenderer::put_DecimateInput Method

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

HRESULT put_DecimateInput(
    VARIANT_BOOL bDecimate
);

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.
