Bitrate Property

Summary
Gets or sets the stream's bit rate in bits per second.
Syntax
C#
C++/CLI
public int Bitrate { get; set; } 
public: 
property int Bitrate { 
   int get(); 
   void set (    int ); 
} 

Property Value

The stream's bit rate in bits per second.

Remarks

Gets or sets the stream's bit rate in bits per second. Call the WMProfile.ReconfigStream method to have the new bit rate take effect. For more information, refer to the Microsoft documentation for IWMStreamConfig.GetBitrate.

Example
C#
using Leadtools; 
using Leadtools.Multimedia; 
using LeadtoolsMultimediaExamples.Fixtures; 
 
 
public bool _result = false; 
public CaptureCtrlForm _form = new CaptureCtrlForm(); 
 
public void StreamTypeExample()

   CaptureCtrl capturectrl = _form.CaptureCtrl; 
 
   try 
   { 
      // reference the profile if available 
      WMProfile CurrentProfile = capturectrl.WMProfile; 
 
      // if we have a profile display the info 
      if (CurrentProfile != null) 
         MessageBox.Show(GetStreamInfo(CurrentProfile), "Stream Info", MessageBoxButtons.OK); 
      _result = true; 
   } 
   catch (Exception) 
   { 
      _result = false; 
   } 
} 
 
// discovering streams

      // where zero denotes maximum frame rate and 100 denotes maximum quality.  
      streamInfo += "\n stream quality: "; 
 
      if (streamConfig.Quality > -1) 
         streamInfo += streamConfig.Quality.ToString(); 
      else
