InterleaveMode Property (CaptureCtrl)

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

Syntax

Visual Basic
C#
C++/CLI

'Declaration
 
Public Overridable Property InterleaveMode As CaptureInterleavingMode

'Usage
 
Dim instance As CaptureCtrl
Dim value As CaptureInterleavingMode
 
instance.InterleaveMode = value
 
value = instance.InterleaveMode

public virtual CaptureInterleavingMode InterleaveMode {get; set;}

public:
virtual property CaptureInterleavingMode InterleaveMode {
   CaptureInterleavingMode get();
   void set (    CaptureInterleavingMode value);
}

Property Value

A CaptureInterleavingMode value specifying the interleave mode.

Remarks

Not all file formats support interleaving. For example, the AVI file format supports interleave mode, while the WMV file format does not. The interleave mode is ignored for those formats that do not support it.

Interleave mode tells the multiplexer (the module that combines audio and video into one file) which method to use to combine data from various streams (video, audio, etc) in the file. Some interleaving modes require more processing and more memory, but generate files more suitable for streaming. Other interleaving modes are faster, and should be used when speed is necessary (for example, during capture).

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