The GetMediaType method retrieves a preferred media type, by index value.
Syntax
HRESULT GetMediaType(
int iPosition,
CMediaType *pMediaType
);
Parameters
iPosition
Zero-based index value.
pMediaType
Pointer to a CMediaType object that receives the media type.
Return Value
Returns an HRESULT value. Possible values include those shown in the following table.
Value | Description |
S_OK | Success |
VFW_S_NO_MORE_ITEMS | Index out of range |
Remarks
This method overrides the CBasePin::GetMediaType method. If the filter's input pin is not connected, the method returns VFW_S_NO_MORE_ITEMS. Otherwise, it calls the filter's CTransformFilter::GetMediaType method to retrieve the media type. The CTransformFilter::GetMediaType method is pure virtual; the filter's derived class must override it.
