Return codeDescription
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.
