This method retrieves the multimedia format type.


HRESULT GetFourCCCodes(
  DWORD* pCount,
  DWORD* pCodes
);

pCount

Number of FOURCC codes in the pCodes array.

pCodes

Array of DWORD media tags formerly used for Microsoft multimedia types.

Returns an HRESULT value.

In the original Microsoft® Windows® multimedia APIs, media types were tagged with 32-bit values created from four 8-bit characters and were known as FOURCC codes. Because FOURCC codes are unique, a one-to-one mapping is possible by allocating a range of 4 billion GUIDs representing FOURCCs.

This method retrieves the FOURCC codes that the current display driver can support.

The number available is obtained by calling the method with a valid pCount pointer, but with pCodes set to NULL. In this case, the pCount variable will be filled in with the number of FOURCC codes available. An application can then allocate enough DWORD values for this many FOURCC codes and call the method again with the array pointer in pCodes.
