Example

using Leadtools; 
using Leadtools.Multimedia; 
using LeadtoolsMultimediaExamples.Fixtures; 
 
 
public bool _result = false; 
public ConvertCtrlForm _form = new ConvertCtrlForm(); 
 
// input and output file names 
string _inFile = Path.Combine(LEAD_VARS.MediaDir, "ConvertCtrl_Source.mpeg"); 
string _outFile = Path.Combine(LEAD_VARS.MediaDir, "ConvertCtrl_PreferredMPEG2SplitterExample.avi"); 
 
public void PreferredMPEG2SplitterExample() 
{ 
   // reference the convert control 
   ConvertCtrl convertctrl = _form.ConvertCtrl; 
 
   try 
   { 
      // set the source file 
      convertctrl.SourceFile = _inFile; 
 
      // select video and audio compressors 
      convertctrl.VideoCompressors.Mpeg2.Selected = true; 
      convertctrl.AudioCompressors.AC3.Selected = true; 
 
      // set the target file and format 
      convertctrl.TargetFile = _outFile; 
      convertctrl.TargetFormat = TargetFormatType.AVI; 
 
      // set the preferred MPEG2 splitter to be the LEAD MPEG2 Transport Demultiplexer. 
      // this avoids a rogue filter with a higher merit from being used to play MPEG2 files. 
      convertctrl.PreferredMPEG2Splitter = Constants.Filter_MPEG2_Transport_Demux; 
 
      // subscribe to the complete event to check our result 
      convertctrl.Complete += new EventHandler(ConvertCtrl_Complete); 
 
      // set the allowed streams 
      convertctrl.AllowedStreams = StreamFormatType.AudioVideoCC; 
 
      // convert it! 
      convertctrl.StartConvert(); 
   } 
   catch (Exception) 
   { 
      _result = false; 
   } 
 
   // 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(); 
} 
 
void ConvertCtrl_Complete(object sender, EventArgs e) 
{ 
   // set the result 
   _result = File.Exists(_outFile); 
}
