CBaseVideoRenderer::GetStdDev (Windows Embedded CE 6.0)

1/6/2010

Estimates the standard deviation in milliseconds between when each frame is due and when it is actually rendered, for per-frame statistics.

Syntax

HRESULT GetStdDev(
  int nSamples,
  int* piResult,
  LONGLONG llSumSq,
  LONGLONG iTot
);

Parameters

  • nSamples
    Integer value that contains the number of video samples received by the video renderer.
  • piResult
    Pointer to an integer value that will contain the standard deviation.
  • llSumSq
    Value that represents the standard deviation, in milliseconds, of all rendered video samples. The lower the value, the more consistent the rendering.
  • iTot
    Value that represents the mean value, in milliseconds, between the stamped time and rendered time for all rendered video samples.

Return Value

Returns NOERROR.
