Bytescout Screen Capturing Video Filter API - Virtual Camera
Bytescout Screen Capturing Filter emulates hardware camera and provides virtual camera filter that can be used to record video from. This emulated camera provides video from the desktop screen.
Every software that supports hardware video devices works with virtual Bytescout Screen Capturing camera as well (see screenshot below to see how the camera can be accessed in the Skype).
So you can easily integrate the virtual screen capturing camera within your application or existing code
Filename: BytescoutVirtualCameraFilter.dll
Works As: DirectX Video Filter and Virtual Camera (so you can use any video capturing software to record video from screen);
Type CaptureAreaSource:
caRegion = 0, // capture the region defined with rectangle at CaptureRectLeft, CaptureRectTop, CaptureRectWidth, CaptureRectHeight
caWindow = 1, // captures the given window (including non-visible(!) windows). See WindowsToCapture and WindowToCapture2 properties to define window to find by its title, class name or window handle). IMPORTANT: may cause flickering on some Windows versions (depends on graphic card as well). You can also crop video capture from window using CaptureRectLeft, CaptureRectTop, CaptureRectWidth, CaptureRectHeight
caMouse = 2, // captures the area around the mouse pointer with the width and height defined by CaptureRectWidth and CaptureRectHeight
caScreen = 3 // capture entire screen
caVisibleWindow = 4 // capture the given window (works for only visible windows(!), for non-visible windows see caWindow(1) mode). See WindowsToCapture and WindowToCapture2 properties to define window to find by its title, class name or window handle). IMPORTANT: may cause flickering on some Windows versions (depends on graphic card as well). You can also crop video capture from window using CaptureRectLeft, CaptureRectTop, CaptureRectWidth, CaptureRectHeight
Property CaptureAreaSource As CaptureAreaSource: area type to capture (caRegion = 0, caWindow=1, caMouse=2, caScreen=3);
Property CaptureRectLeft As Long: left coordinate of the rectangle to capture from (in .CaptureAreaSource=caRegion(0) mode)
Property CaptureRectTop As Long: top coordinate of the rectangle to capture from (in .CaptureAreaSource=caRegion(0) mode)
Property CaptureRectWidth As Long: width of the rectangle to capture from (in .CaptureAreaSource=caRegion(0) and .CaptureAreaSource=caMouse(2) modes). In .CaptureAreaSource=caMouse(2) this property defines the width of the rectangle near the mouse cursor
Property CaptureRectHeight As Long: height of the rectangle to capture from (in .CaptureAreaSource=caRegion(0) and .CaptureAreaSource=caMouse(2) modes). In .CaptureAreaSource=caMouse(2) this property defines the height of the rectangle near the mouse cursor
Property WindowToCapture As String: partial name of the window to capture from (in .CaptureAreaSource=caWindow(1) mode). You can provide partial name of the window or partial class name.
Property WindowToCapture2 As OLE_HANDLE: window handle of the window to capture from (in .CaptureAreaSource=caWindow(1) mode).
Property FPS As FLOAT: FPS of the output video;
Property ResizeOutput As Boolean: controls if filter should resize source video into output width and height. True by default.
Property OutputWidth As Long: output video width
Property OutputHeight As Long: output video height
Property CaptureMouseCursor As Boolean: controls if filter should record mouse cursor in the video. True by default.
Property AnimateMouseButtons As Boolean: controls if filter should display a small animation to indicate which mouse button has been clicked by user. False by default
Property AnimateMouseClicks As Boolean:controls if filter should display a small animation (animated circles) when user clicks using the mouse in the output video. True by default.
Property MouseCursorLeftClickAnimationColor As OLE_COLOR: defines the color of the animation for left mouse button clicks. Default color is Blue.
Property MouseCursorRightClickAnimationColor As OLE_COLOR: defines the color of the animation for right mouse button clicks. Default color is Green.
Property MouseCursorLeftClickAnimationColor As OLE_COLOR: defines the color of the animation for left mouse button clicks. Default color is Blue.
Property MouseAnimationDuration As OLE_COLOR: defines the duration of the animation for mouse button clicks. Default duration is 1000 ms (1 sec).
Property ShowMouseHotSpot As Boolean: show/hide the semitrasnparent hotspot around the mouse cursor (to make it easier to follow the mouse on the output video). True by default.
Property MouseHotSpotColor As OLE_COLOR: color of the hotspot around the mouse. Default is Yellow.
Property Version As String: returns text string with version information;
Property UseRegistryKey As String: defines the registry key to store settings. Default value is HKCU\Software\Bytescout\Screen Capturing Filter\
Property UseRegistryHive As Long: controls the Windows Registry Hive;
Method UseDefaultRegistryKey: resets the filter to use default registry key (HKCU\Software\Bytescout\Screen Capturing Filter\)
Property RegistrationName As String: set Registration Name to unlock Full version;
Property RegistrationKey As String: set Registration Key to unlock Full version;
