Code samples on recording video from the region on the screen:

Code samples below are demonstration use of Screen Capturing SDK for screen video recording from a predefined region on screen. The region is defined through the following properties: CaptureRectLeft, CaptureRectTop, CaptureRectWidth, CaptureRectHeight.



The sound track for the video is recorded from default recording line by default (if user need to record voice comments then you should change audio line to Mic line source)

1) Visual Basic .NET

Create new VB.NET Console project in Visual Studio. Click Project | Add Reference.. and add the reference to Bytescout Screen Capturing Lib on the COM tab and click OK. Then use the code snippet below.

Imports System.Threading

Imports System.Diagnostics



Imports BytescoutScreenCapturingLib ' import bytescout screen capturer activex object



Module Module1



  Sub Main()

  ' create capturer class

    Dim capturer As New CapturerClass()

  ' set capturing area to the region type (to capture from given region on the screen)

    capturer.CapturingType = CaptureAreaType.catRegion



  ' output video filename

    capturer.OutputFileName = "GivenRegionCaptured.avi"



    ' set coordinates of the region to capture video from

    capturer.CaptureRectLeft = 50

    capturer.CaptureRectTop = 50



    capturer.CaptureRectWidth = 640

    capturer.CaptureRectHeight = 480



    ' set width and height of output video

    capturer.OutputWidth = 320

    capturer.OutputHeight = 240



  ' start capturing

    capturer.Run()



  ' wait for 10 seconds

    Thread.Sleep(10000)



  ' stop capturing and flush AVI video file into the disk

    capturer.Stop()





    ' open the output video

    Process.Start("GivenRegionCaptured.avi")

  End Sub



End Module

2) Visual C# .NET

Create new C# Console project in Visual Studio. Click Project | Add Reference.. and add the reference to Bytescout Screen Capturing Lib on the COM tab and click OK. Then use the code snippet below.

using System;

using System.Collections.Generic;

using System.Text;

using System.Threading;

using System.Diagnostics;



using BytescoutScreenCapturingLib; // import bytescout screen capturing activex object



namespace SimpleCaptureCSharp

{

  class Program

  {

    static void Main(string[] args)

    {

      CapturerClass capturer = new CapturerClass(); // create new screen capturer object



      capturer.CapturingType = CaptureAreaType.catRegion; // set capturing area type to catRegion to capture from the given region

      

      capturer.OutputFileName = "RegionCapture.avi"; // set output video filename



      capturer.CaptureRectLeft = 100; // set left coordinate of the rectangle region to record video from

      capturer.CaptureRectTop = 100; // set top coordinate of the rectangle region to record video from



      capturer.CaptureRectWidth = 640; // set width of the rectangle region to record video from

      capturer.CaptureRectHeight = 480; // set height of the rectangle region to record video from



      // set output video width and height

      capturer.OutputWidth = 320;

      capturer.OutputHeight = 240;



      capturer.Run(); // run screen video capturing



      Thread.Sleep(15000); // wait for 15 seconds



      capturer.Stop(); // stop video capturing



      Process.Start("RegionCapture.avi");

    }

  }

}

2) Visual Basic 6 and VBScript (VBS)

' create video capturer activex object

Set capturer = CreateObject("BytescoutScreenCapturing.Capturer")



' set output video file name

capturer.OutputFileName = "CaptureScreenVbs.avi"



' set capturing type to the caRegion =0 to capture the given region

capturer.CapturingType = 0



' set left coordinate of the rectangle to capture from

capturer.CaptureRectLeft = 100

' set top coordinate of the rectangle to capture from

capturer.CaptureRectTop = 100



' set width of the rectangle to capture from

capturer.CaptureRectWidth = 320

' set height of the rectangle to capture from

capturer.CaptureRectHeight = 240



MsgBox "This script will record video from the screen from region (100,100, 420, 350) for 10 seconds. Output video will go to PredefinedRegionCaptured.avi"



' run video capturing

capturer.Run()



' wait for 10 seconds (10000 msec)

WScript.Sleep(10000)



' stop capturing

capturer.Stop()



' destroy Capturer object so the video will be saved into the disk

Set capturer = Nothing
