IAMVideoProcAmp parameter type is 64bit?

According to IAMVideoProcAmp
long type maybe 32 bit not c# long type?

long in C/C++is generally (and certainly in Windows SDK header files) considered as a 32-bit integer, so it's equivalent to C# int (.NET System.Int32)

Sorry, I gave the wrong example.
this GetRange has c++ long type,
long type maybe change to int type below code

[ComImport]
[Guid("c6e13360-30ac-11d0-a18c-00a0c9118956")]
[InterfaceType(ComInterfaceType.InterfaceIsIUnknown)]
public interface IAMVideoProcAmp
{
    [PreserveSig]
    HRESULT GetRange(int Property, out long pMin, out long pMax, out long pSteppingDelta, out long pDefault, out long pCapsFlags);

    [PreserveSig]
    HRESULT Set(int Property, int lValue, int Flags);

    [PreserveSig]
    HRESULT Get(int Property, out long lValue, out long Flags);
}

Same answer, long C++ is int C# so there's nothing to change.
