Example
C#
using Leadtools; 
using Leadtools.MediaFoundation; 
using LeadtoolsMediaFoundationExamples.Fixtures; 
 
 
public bool _result = false; 
public CaptureCtrlForm _form = new CaptureCtrlForm(); 
 
public void CopyToExample() 
{ 
   // reference the capture control  
   CaptureCtrl capturectrl = _form.CaptureCtrl; 
 
   try 
   { 
      // set an audio device first, you should use your audio device name here 
      if (capturectrl.AudioDevices["USB"] == null) 
         throw new Exception("No USB audio device available"); 
 
      capturectrl.AudioDevices["USB"].Selected = true; 
 
      // reference the target formats collection 
      TargetFormats formats = capturectrl.TargetFormats; 
 
      // reference the target format object 
      TargetFormat tf = formats[TargetFormatType.MP4]; 
 
      // reference the target audio formats object 
      TargetAudioFormats taformats = tf.AudioFormats; 
 
      // allocate a new array for the copied target audio formats  
      TargetAudioFormat[] copiedFormats = new TargetAudioFormat[taformats.Count]; 
 
      // copy them 
      taformats.CopyTo(copiedFormats, 0); 
 
      // set the result to what we expect 
      _result = (copiedFormats.Length == formats.Count); 
   }
