VideoCompression Property

Summary

Gets the type of compression used for the current stream in the current source media file.

Syntax

C++/CLI

public int VideoCompression { get; }

public: 
property int VideoCompression { 
   int get(); 
}

Property Value

A value (FOURCC code) representing the type of compression used for the current stream in the current source media file.

Remarks

The video compression type is indicated by a FOURCC value. For a list of FOURCC values, refer to the Microsoft documentation on FOURCC Codes. This property will not be updated if the current stream is not a video stream. This property is updated automatically when the CurrentStream property is set to a video stream. The current source media file, found in the SourceFile property, is the file that the MediaInfo object gets information for. The SourceFile property must be set before retrieving information from any of the other MediaInfo properties.

Example

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; 
   } 
}
