VideoCompressor Property

Summary

Gets or sets the video compressor's name.

Syntax

C++/CLI

public string VideoCompressor { get; set; }

public: 
property String^ VideoCompressor { 
   String^ get(); 
   void set (    String^ ); 
}

Property Value

A string value representing the video compressor's name.

Remarks

A video compressor is a module or algorithm used to compress video data. Video compressors are also known as video encoders. When the format is selected, the video stream The portion of the file holding the video data will be connected to this compressor before any multiplexer. A multiplexer is a module that combines audio and video into one file. If this value is undefined (empty string), then the video stream will be directly connected to a multiplexer. Attempting to set this value on a ReadOnly item will result in an error. For more information, refer to the Error Codes.

   // 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.
