The current source media file, set using IltmmMediaInfo::put_SourceFile, is the file for which the IltmmMediaInfo interface/object gets information. IltmmMediaInfo::put_SourceFile must be called before calling any of the other IltmmMediaInfo functions used for retrieving information.

To set the current stream, call IltmmMediaInfo::put_CurrentStream.
