SourceStream Property

Summary

Gets or sets the media source stream.

Syntax

C++/CLI

public virtual Stream SourceStream { get; set; }

public: 
virtual property Stream^ SourceStream { 
   Stream^ get(); 
   void set (    Stream^ ); 
}

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. For more information, refer to the Error Codes. Note: When setting this property, the Play control must be in the stopped state.

Example

using Leadtools; 
using Leadtools.MediaFoundation; 
using LeadtoolsMediaFoundationExamples.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; 
 
      // set event handler 
      playctrl.StateChanged += new StateChangedEventHandler(PlayCtrl_StateChanged); 
 
      // set the source stream 
      playctrl.SourceStream = new StreamReader(inFile).BaseStream; 
 
      // set the allowed streams 
      playctrl.AllowedStreams = StreamFormatType.Audio; 
 
      // 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_StateChanged(object sender, StateChangedEventArgs e) 
{ 
   // set the result to what we expect 
   _result = (e.lastState == PlayState.Running && e.state == PlayState.Stopped); 
} 
 
static class LEAD_VARS 
{ 
   public const string MediaDir = @"C:\LEADTOOLS23\Media"; 
}
