Screen source

Products: Video Capture SDK .Net

Screen capture is a process of copying what you see on your screen.

Video Capture SDK .Net allows you to capture the entire screen, a single window, or a selected area of the screen.

Capture screen area​

To capture a screen area, use the ScreenCaptureSourceSettings class.

// Set screen capture source settings
VideoCapture1.Screen_Capture_Source = new ScreenCaptureSourceSettings
{
    FullScreen = false,
    Left = 0,
    Top = 0,
    Width = 640,
    Height = 480,
    DisplayIndex = 0,
    FrameRate = new VideoFrameRate(25),
    AllowCaptureMouseCursor = true
};

Capture full screen​

To capture the full screen, use the ScreenCaptureSourceSettings class.

// Set screen capture source settings
VideoCapture1.Screen_Capture_Source = new ScreenCaptureSourceSettings
{
    FullScreen = true,
    DisplayIndex = 0,
    FrameRate = new VideoFrameRate(25),
    AllowCaptureMouseCursor = true
};

Capture window​

To capture a window, use the ScreenCaptureSourceSettings class.

// Set screen capture source settings
VideoCapture1.Screen_Capture_Source = new ScreenCaptureSourceSettings
{
    FullScreen = false,
    WindowHandle = windowHandle,
    FrameRate = new VideoFrameRate(25),
    AllowCaptureMouseCursor = true
};

To capture the mouse cursor, set the AllowCaptureMouseCursor property to true.

Use DisplayIndex to select the display to capture. The default value is 0.

Use ScreenPreview or ScreenCapture mode to preview or capture video from the device.
