Mux Property

Summary

Gets or sets the multiplexer's name

Syntax

C++

public string Mux { get; set; }

Public Property Mux As String

public: 
property String^ Mux { 
   String^ get(); 
   void set (    String^ ); 
}

Property Value

A string value representing the multiplexer's name

Remarks

A multiplexer is a module that combines audio and video into one file. When the format is selected, all streams will be combined in this filter before being passed to the TargetFormat.Sink property. Attempting to set this value on a ReadOnly item will result in an error. For more information, refer to the Error Codes.
