Screen recording of a region around the mouse ready-to-use code sample:
This sample code demonstrates how to use Screen Capturing SDK to record video from the dynamic region around the mouse. The region is defined by the width and height. This method works as a virtual camera that follows to the mouse cursor.
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.catMouse ' output video filename capturer.OutputFileName = "RegionAroundMouseCaptured.avi" ' set width and height of the rectangle around the mouse to capture video from capturer.CaptureRectWidth = 320 capturer.CaptureRectHeight = 240 ' start capturing capturer.Run() ' wait for 15 seconds Thread.Sleep(15000) ' stop capturing and flush AVI video file into the disk capturer.Stop() ' open the output video Process.Start("RegionAroundMouseCaptured.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.catMouse; // set capturing area type to catScreen to capture whole screen capturer.OutputFileName = "EntireScreenCaptured.avi"; // set output video filename // set width and height of the region around the mouse capturer.CaptureRectWidth = 320 capturer.CaptureRectHeight = 240 // 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("EntireScreenCaptured.avi"); } } }
3) Visual Basic 6 and VBScript (VBS)
' create video capturer activex object Set capturer = CreateObject("BytescoutScreenCapturing.Capturer") ' set output video file name capturer.OutputFileName = "RegionAroundMouseCaptured.avi" ' set capturing type to the caMouse =2 to capture the region around the mouse curosr. You can also set to caRegion = 0 (to record from the given rectangle on screen) or to caScreen = 3 (to capture entire screen) capturer.CapturingType = 2 ' set width of the rectangle to capture from capturer.CaptureRectWidth = 320 ' set height of the rectangle to capture from capturer.CaptureRectHeight = 240 MsgBox "Script will record 320x240 region around the mouse cursor for 10 seconds. Output video will go to CaptureScreenVbs.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
