  • Note   This interface is deprecated. New applications should not use it.

Sets the format of the current media stream.

  HRESULT SetFormat(
  const DDSURFACEDESC *pDDSurfaceDesc,
  IDirectDrawPalette *pDirectDrawPalette
  );

Parameters

pDDSurfaceDesc

[in] Pointer to a DirectDraw surface description that contains the new format.

pDirectDrawPalette

[in] Optional parameter that is a pointer to an IDirectDrawPalette interface.

Return Values

Returns one of the following values.

Return code Description
DDERR_INVALIDSURFACETYPE The specified format is incompatible with the current stream.
MS_E_SAMPLEALLOC Can't change the format because one or more stream samples are already allocated for this stream.
