LEADTOOLS Multimedia (Leadtools.Multimedia assembly)

VideoWidth Property (MediaInfo)

Show in webframe
Example 



Gets the video width, in pixels, for the current stream in the current source media file.
Syntax
'Declaration
 
Public ReadOnly Property VideoWidth As Integer
'Usage
 
Dim instance As MediaInfo
Dim value As Integer
 
value = instance.VideoWidth
public int VideoWidth {get;}
public:
property int VideoWidth {
   int get();
}

Property Value

A value representing the current video width in pixels.
Remarks
This property is updated automatically when the CurrentStream property is set to the current stream, if the current stream is a video stream. This property will not be updated if the current stream is not 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.
