MinimumFragmentDuration Property

Summary

Gets or sets the output minimum fragment duration in seconds.

Syntax

C#
VB
C++
public double MinimumFragmentDuration {get; set;} 
Public Property MinimumFragmentDuration As Double 
public: 
property double MinimumFragmentDuration { 
   double get(); 
   void set (    double ); 
}

Property Value

Double value that represents the minimum output fragment duration, in seconds.

Remarks

The minimum output fragment duration indicates the minimum time to accumulate a fragment for delivery to all the protocols. The default value is 2 seconds. Setting this to a smaller value can result in reduced latency. However, some protocols will not function with a value that is too small.

Example
