UsingDVDecoder Property

Summary

Gets a value that indicates whether the state of the DV Decoder is in use.

Syntax
C#
VB
C++
public virtual bool UsingDVDecoder { get; } 
Public Overridable ReadOnly Property UsingDVDecoder As Boolean 
public: 
virtual property bool UsingDVDecoder { 
   bool get(); 
}

true if the DV decoder is being used; otherwise it is false.

using Leadtools.Multimedia; 
using LeadtoolsMultimediaExamples.Fixtures; 
 
public bool _result = false; 
public PlayCtrlForm _form = new PlayCtrlForm();
