OutputStreams Property

Summary
Gets the number of output streams available in the current program.
Syntax
C#
C++/CLI
public int OutputStreams { get; } 
public: 
property int OutputStreams { 
   int get(); 
} 

Property Value

A value representing the number of output streams available in the current program.

Remarks

The current source media file is the file that the MediaInfo object gets information for. To set the current source media file, set the SourceFile property. The source file has one or more programs and each program has one or more output streams. The value of this property might change if you change the value of the current program using the CurrentProgram property. The value of this property can be used to iterate through all streams, acquiring information on each. To set the current stream, set the CurrentStream property. Once the current stream has been set, other MediaInfo properties are updated with information about the current stream.

Example
C#
using Leadtools; 
using Leadtools.Multimedia; 
using LeadtoolsMultimediaExamples.Fixtures; 
 
 
public PlayCtrlForm _form = new PlayCtrlForm(); 
public bool _result = false; 
 
public void ResetSourceExample() 
{ 
   // reference the play control 
   PlayCtrl playctrl = _form.PlayCtrl; 
 
   // input file 
   string inFile = Path.Combine(LEAD_VARS.MediaDir, "MediaInfo_Source.avi"); 
   string info = string.Empty; 
 
   try 
   { 
      // create a new media info object 
      MediaInfo mi = new MediaInfo(); 
 
      // set the input and output files 
      mi.SourceFile = inFile; 
 
      // set the info string 
      info = string.Format("Source File={0}\nSource File Size={1}\nSource BitRate={2}\nDuration={3}\nVideoBitRate={4}\nVideoBitCount={5}\n\nAre these values correct?", 
         // AudioBitsPerSample={5}\nAudioChannels={6}\n  
         mi.SourceFile, mi.SourceFileSize, mi.SourceBitRate, mi.SourceDuration, mi.VideoBitRate, mi.VideoBitCount); //, mi.AudioBitsPerSample, mi.AudioChannels); 
 
      // verify the values 
      _result = (MessageBox.Show(_form, info, "Media Info", MessageBoxButtons.YesNo) == DialogResult.Yes); 
 
      // reset the source 
      mi.ResetSource(); 
 
      // set the result to what we expect 
      _result = (mi.SourceFile == null); 
   } 
   catch (Exception) 
   { 
      _result = false; 
   } 
}
