public string SourceFormatName { get; } public:property String^ SourceFormatName {String^ get();}
A string value representing the name of the current source media format.
Gets the name of the format of the current source media file. This property is updated automatically when the SourceFile property is set to the current source media file. The current source media file is found in the SourceFile property. This is the file that the MediaInfo object gets information for. The SourceFile property must be set before retrieving information from any of the other MediaInfo properties. Call the ResetSource method to release the source file when it is no longer needed.
