UsingDVDecoder Property

Summary

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

Syntax

C++/CLI

public virtual bool UsingDVDecoder { get; }

public: 
virtual property bool UsingDVDecoder { 
   bool get(); 
}

Property Value

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

Remarks

If the DV decoder is being used, change the size of the preview using the DVDecoderResolution property. Doing so affects the playback of the currently loaded file.

Example

using Leadtools; 
using Leadtools.Multimedia; 
using LeadtoolsMultimediaExamples.Fixtures; 
 
 
public bool _result = false; 
public PlayCtrlForm _form = new PlayCtrlForm(); 
 
public void UsingDVDecoderExample() 
{ 
   // reference the play control 
   PlayCtrl playctrl = _form.PlayCtrl; 
 
   // input file 
   string inFile = Path.Combine(LEAD_VARS.MediaDir, "PlayCtrl_SourceDVSD.avi"); 
 
   try 
   { 
      // turn off auto start 
      playctrl.AutoStart = false; 
 
      // set the source for conversion 
      playctrl.SourceFile = inFile; 
 
      // check to see if we are using the DVDecoder 
      if (playctrl.UsingDVDecoder) 
      { 
         // set the DV resolution to full 
         playctrl.DVDecoderResolution = DVResolution.Full; 
         // set the result 
         _result = true; 
      } 
 
      // see if we have a video decompressor dialog and show it 
      if (playctrl.HasDialog(PlayDlg.VideoDecompressor)) 
         playctrl.ShowDialog(PlayDlg.VideoDecompressor, _form); 
 
      // start the capture process 
      playctrl.Run(); 
 
      // 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 (playctrl.State == PlayState.Running) 
         Application.DoEvents(); 
   } 
   catch (Exception) 
   { 
      _result = false; 
   } 
}
