Returns a UINT32 value from an attribute store, or a default value if the attribute is not present.
Pointer to the IMFAttributes interface of the attribute store.
GUID that identifies which value to retrieve.
Default value to return if the attribute store does not contain the specified attribute.
Returns a UINT32 value.
This helper function queries the attribute store for the UINT32 value specified by guidKey. If the value is not present or does not have type UINT32, the function returns unDefault.
This function is convenient because it never returns a failure code. However, if the attribute in question does not have a meaningful default value, you should call IMFAttributes::GetUINT32 and check for MF_E_ATTRIBUTENOTFOUND.
