MultimediaSupport Class

Summary
Unlocks the Multimedia features, filters, codecs and objects.
Syntax
C#
C++/CLI
public static class MultimediaSupport 
public ref class MultimediaSupport abstract sealed  
Remarks

This is a static class, so it does not need to be created. This class is internally calling the DSKERNEL2.DLL ILMDSKernel2 interface. So you can either call the methods in this class or use the ILMDSKernel2 interface directly.

A typical use is to call UnlockModule when the application starts and LockModules at before the application exits.

Example
C#
using Leadtools; 
using Leadtools.MediaFoundation; 
using LeadtoolsMediaFoundationExamples.Fixtures; 
 
 
public bool _result = false; 
 
public void MultimediaSupportExample() 
{ 
   // pszKey is a string containing the serial number. It is defined like this: 
   // string pszKey = "MySerial"; 
   string pszAppId = "My Test Application"; 
 
   try 
   { 
      // unlock the multimedia feature 
      Leadtools.MediaFoundation.Common.MultimediaSupport.UnlockModule(pszKey, 
                                                                 Leadtools.MediaFoundation.Common.LockType.Application, 
                                                                 pszAppId); 
   } 
   catch 
   { 
      return; 
   } 
 
   // [use the multimedia feature here] 
 
   // lock the multimedia feature before exiting the app 
   try 
   { 
      Leadtools.MediaFoundation.Common.MultimediaSupport.LockModules(Leadtools.MediaFoundation.Common.LockType.Application, 
                                                                pszAppId); 
   } 
   catch 
   { 
      return; 
   } 
   _result = true; 
}
