Several video streams mixing, Picture-in-Picture in Video Capture SDK .Net

SDK can mix several video streams with different resolutions and frame rates.

1. Set video mixing mode using PIP_Mode property.

Horizontal stack

VideoCapture1.PIP_Mode = VFPIPMode.Horizontal;

Vertical stack

VideoCapture1.PIP_Mode = VFPIPMode.Vertical;

2×2 square

VideoCapture1.PIP_Mode = VFPIPMode.Mode2x2;

Custom coordinates and output video size

VideoCapture1.PIP_Mode = VFPIPMode.Custom;
VideoCapture1.PIP_CustomOutputSize_Set(1920, 1080);

2. Add sources

First source is the main configured source. Screen for screen capture mode, camera for video capture mode, etc. Additional sources can be added using PIP API. Add video capture device:

VideoCapture1.PIP_Sources_Add_VideoCaptureDevice(
                    deviceName,
                    format,
                    false,
                    frameRate,
                    input,
                    left,
                    top,
                    width,
                    height);

Add IP camera source:

var ipCameraSource= new IPCameraSourceSettings
            {
                URL = "camera url"
            };

// set other IP camera parameters
// ...


VideoCapture1.PIP_Sources_Add_IPCamera(
    ipCameraSource,
    left,
    top,
    width,
    height);

Add screen source:

ScreenCaptureSourceSettings screenSource = new ScreenCaptureSourceSettings();
screenSource.Mode = VFScreenCaptureMode.Screen;
screenSource.FullScreen = true;
VideoCapture1.PIP_Sources_Add_ScreenSource(
    screenSource,
    left,
    top,
    width,
    height);

3. Update on-the-fly source position and parameters (0 is major source, 1 and later – sources added using PIP API):

VideoCapture1.PIP_Sources_SetSourcePosition(
    index,
    left,
    top,
    width,
    height);

bool transparency = 127; // (0-255)
bool flipX = false;
bool flipY = false;

VideoCapture1.PIP_Sources_SetSourceSettings(transparency , transparency, flipX, flipY);
