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;

2x2 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);

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);
