Comments

This function allows the user to store a complete media file in a SAFEARRAY and use it as the source for the conversion process. The user is responsible for allocating, initializing, and freeing the array. However, the user should not free the array while the convert object holds a reference to it. The ResetSource function should be called to stop the convert object from accessing the array. The SourceType will be set to ltmfConvert_Source_Array.
