InterleaveMode Property (ConvertCtrl)

Summary

Gets or sets the current interleave mode used when writing the target file.

Syntax

C++

public virtual Leadtools.Multimedia.ConvertInterleavingMode InterleaveMode {get; set;}

Public Overridable Property InterleaveMode As Leadtools.Multimedia.ConvertInterleavingMode

public: 
virtual property Leadtools.Multimedia.ConvertInterleavingMode InterleaveMode { 
   Leadtools.Multimedia.ConvertInterleavingMode get(); 
   void set (    Leadtools.Multimedia.ConvertInterleavingMode ); 
}

Property Value

An ConvertInterleavingMode enumeration value specifying the interleave mode.

Remarks

Not all file formats support interleaving. For example, AVI file format supports interleave mode, while WMV file format does not. The interleave mode is ignored for the formats that do not support it. Interleave mode tells the multiplexer (the module that combines audio and video into one file) the method for combining data from various streams (video, audio, etc) in the file. Some interleaving modes will require more processing and more memory, but will generate files more suitable for streaming. Other interleaving modes will be faster, and should be used when speed is necessary (for example, during capture).

For a list of possible values, refer to the ConvertInterleavingMode enumeration value.

   // but you should not need to if running from a Windows Forms application.
