CMediaSample::SetPreroll

Sets the preroll property. If TRUE, this sample is for preroll only and should not be displayed.

HRESULT SetPreroll(
BOOL bIsPreroll );

Parameters

  • bIsPreroll
    Set to TRUE to specify the media sample as a preroll sample, or FALSE otherwise.

Return Values

Remarks

This member function implements the IMediaSample::SetPreroll method. It sets the value of the m_dwFlags Sample_Preroll flag to the value of bIsPreroll. Preroll samples are samples that are processed but not displayed, and are located in the media stream before the displayable samples.
