}

Property Value

A System.IO.Stream object for the media source stream.

Remarks

Use this property to assign a Stream-derived object as the media source for the conversion process. The SourceType will be set to SourceObjectType.Stream. Assignment can raise an error exception.

Example

using Leadtools; 
using Leadtools.Multimedia; 
using LeadtoolsMultimediaExamples.Fixtures; 
 
 
public bool _result = false; 
public PlayCtrlForm _form = new PlayCtrlForm(); 
 
public void SourceStreamExample() 
{ 
   // reference the play control 
   PlayCtrl playctrl = _form.PlayCtrl; 
 
   // input and output file names 
   string inFile = Path.Combine(LEAD_VARS.MediaDir, "PlayCtrl_Source.avi"); 
 
   try 
   { 
      // turn off auto start 
      playctrl.AutoStart = false; 
 
      // subscribe to the complete event to check our result 
      playctrl.MediaEvent += new MediaEventHandler(PlayCtrl_MediaEvent); 
 
      // set the source stream 
      playctrl.SourceStream = new StreamReader(inFile).BaseStream; 
 
      // set the allowed streams 
      playctrl.AllowedStreams = StreamFormatType.AudioVideoCC; 
 
      // play it! 
      playctrl.Run(); 
   } 
   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 (playctrl.State == PlayState.Running) 
      Application.DoEvents(); 
} 
 
void PlayCtrl_MediaEvent(object sender, MediaEventArgs e) 
{ 
   // set the result 
   if (e.eventCode == MediaEventCode.EC_COMPLETE) 
      _result = true; 
} 
 
static class LEAD_VARS 
{ 
   public const string MediaDir = @"C:\LEADTOOLS23\Media";
