UseDeviceEncoding Property

Summary
Queries or sets whether to use device encoding.
Syntax
C#
C++/CLI
public bool UseDeviceEncoding { get; set; } 
public: 
property bool UseDeviceEncoding { 
   bool get(); 
   void set (    bool ); 
} 

Property Value

if true then the device encoding should be used. if false it will not be used.

Remarks

If a selected device outputs the proper encoding, then setting it to true will not recompress the output. In this case, all the output encoding parameters will be ignored. Not every device outputs data that performs well with all the streaming protocols, hence evaluate the use of this option on a per device basis.
