Comments

To get the current source media file, call IltmmMediaInfo::get_SourceFile.

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

Call IltmmMediaInfo::ResetSource to release the source file when it is no longer needed.
