WMScripter Property

Summary

Provides a way to get the WMScript object.

Syntax

C++/CLI

public WMScript WMScripter { get; }

public: 
property WMScript^ WMScripter { 
   WMScript^ get(); 
}

Property Value

A WMScript object, which can be used to manage the Windows Media Script commands.

Remarks

The object is read-only and can be null if the TargetFormat property is not set to TargetFormatType.WMVMux or TargetFormatType.ASFMux. You can keep a copy of the object but only as long as the target format does not change. If the target format changes, get the object again. For more information on Windows Media Script Commands, refer to WMScript object.

Example

using Leadtools; 
using Leadtools.Multimedia; 
using LeadtoolsMultimediaExamples.Fixtures; 
 
 
public bool _result = false; 
public ConvertCtrlForm _form = new ConvertCtrlForm(); 
 
public void AddHeaderScriptExample() 
{ 
   ConvertCtrl convertctrl = _form.ConvertCtrl; 
   string inFile = Path.Combine(LEAD_VARS.MediaDir, "ConvertCtrl_Source.avi"); 
   string outFile = Path.Combine(LEAD_VARS.MediaDir, "WMScript_AddHeaderScriptExample.wmv"); 
 
   try 
   { 
      convertctrl.TargetFormat = TargetFormatType.WMVMux; 
      convertctrl.SourceFile = inFile; 
      convertctrl.TargetFile = outFile; 
      WMScript mux = convertctrl.WMScripter; 
      if (mux == null) 
      { 
         _result = false; 
         return; 
      }

      if (mux.HeaderScriptCount > 0) 
         mux.RemoveAllHeaderScripts(); 
 
      WriteScript(convertctrl, mux); 
 
      // run the convert 
      convertctrl.StartConvert(); 
   } 
   catch (Exception) 
   { 
      _result = false; 
      return; 
   } 
 
   // we'll loop on the state and pump messages for this example. 
   // but you should not need to if running from a Windows Forms application. 
   while (convertctrl.State == ConvertState.Running) 
      Application.DoEvents(); 
 
   // set the result 
   _result = true; 
}

{ 
   double duration = convertctrl.Duration; 
 
   for (double t = 0.0; t < duration; t += 1.0) 
   { 
      String sz = String.Format("Sample caption script at {0} seconds", t); 
      mux.AddHeaderScript("caption", sz, t); 
   }
