UseDeviceEncoding Property

Queries or sets whether to use device encoding.

Syntax

C#
Visual Basic
Objective-C
Java
C++

public bool UseDeviceEncoding {get; set;}

'Declaration

Public Property UseDeviceEncoding As Boolean

'Usage

Dim instance As LiveStream
Dim value As Boolean
 
instance.UseDeviceEncoding = value
 
value = instance.UseDeviceEncoding

public:
property bool UseDeviceEncoding {
   bool get();
   void set (    bool value);
}

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.

Example

Silverlight C#
