Comments

The current source media file, set using this function, is the file for which the IltmmMediaInfo interface/object gets information.

This function must be called before calling most of the other IltmmMediaInfo function used for retrieving information. If IltmmMediaInfo::get_OutputStreams is called before IltmmMediaInfo::put_SourceFile is called, IltmmMediaInfo::get_OutputStreams will update the Stream parameter with 0 and return S_OK. If any of the other IltmmMediaInfo functions are called before IltmmMediaInfo::put_SourceFile is called, they will return an error.

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

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