IVMRDeinterlaceControl::GetActualDeinterlaceMode

-description

[The feature associated with this page, DirectShow, is a legacy feature. It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation. Those features have been optimized for Windows 10 and Windows 11. Microsoft strongly recommends that new code use MediaPlayer, IMFMediaEngine and Audio/Video Capture in Media Foundation instead of DirectShow, when possible. Microsoft suggests that existing code that uses the legacy APIs be rewritten to use the new APIs if possible.]

The GetActualDeinterlaceMode method returns the deinterlacing mode that the VMR is using for a specified stream.

-parameters

-param dwStreamID [in]

Index of the video stream.

-param lpDeinterlaceMode [out]

Pointer to a variable that receives a GUID value that identifies the deinterlacing mode. The method returns GUID_NULL if the VMR has not initialized the deinterlacing hardware, or if the VMR determines that this stream should not be deinterlaced.

-returns

Returns an HRESULT value. Possible values include the following:

Return code	Description
E_INVALIDARG	Invalid stream number.
E_POINTER	NULL pointer argument.
S_OK	Success.
VFW_E_VMR_NOT_IN_MIXER_MODE	The VMR is not in mixer mode.
