The GetDeinterlacePrefs method queries how the VMR will select a deinterlacing mode if it cannot use the preferred deinterlacing mode.
Syntax
HRESULT GetDeinterlacePrefs(
DWORD *lpdwDeinterlacePrefs
);
Parameters
lpdwDeinterlacePrefs
[in] Pointer to a variable that receives a member of the VMRDeinterlacePrefs enumeration.
Return Values
Returns an HRESULT value. Possible values include the following:
| Return Code | Description |
| E_POINTER | NULL pointer argument. |
| S_OK | Success. |
| VFW_E_VMR_NOT_IN_MIXER_MODE | The VMR is not in mixer mode. |
Remarks
By default, the preferred deinterlacing mode is the first mode reported by the driver. The application can set the preferred mode by calling the IVMRDeinterlaceControl::SetDeinterlaceMode method. If the VMR cannot use the preferred mode, it will fall back to another mode as specified by the dwDeinterlacePrefs parameter.
