NS_E_WMG_NOSDKINTERFACE
NS_E_WMG_NOSDKINTERFACE: what the result means
NS_E_WMG_NOSDKINTERFACE (0xC00D1056) means the graph object being used does not expose the Windows Media SDK interface required by the requested operation.
What to capture
Record the concrete object/filter being queried, requested interface identifier, object creation path and the graph membership at the time of the query.
Focused verification
Query the interface on the object that is documented to provide it before changing graph topology. Success on another object indicates an object-selection problem, not a media-format failure.
