NDI source

Products: Video Capture SDK .Net

Engines: VideoCaptureCore, VideoCaptureCoreX

The NDI source is a network video source. It can be used to capture video from NDI cameras and NDI-enabled software.

To use NDI, you'll need to install the NDI SDK or NDI Tools.

Enumerating NDI Sources

Enumerate NDI sources and add them to the combo box.

VideoCaptureCore

var lst = await VideoCapture1.IP_Camera_NDI_ListSourcesAsync();
foreach (var uri in lst)
{
    cbIPCameraURL.Items.Add(uri);
}

VideoCaptureCoreX

var lst = await DeviceEnumerator.Shared.NDISourcesAsync();
foreach (var uri in lst)
{
    cbIPCameraURL.Items.Add(uri.URL);
}

Set NDI source

VideoCaptureCore

// Create an IP camera source settings object
settings = new IPCameraSourceSettings
            {
                URL = new Uri("NDI source URL")
            };

// Set the source type to NDI
settings.Type = IPSourceEngine.NDI;

// Enable or disable audio capture
settings.AudioCapture = false; 

// Set login information if needed
settings.Login = "username";
settings.Password = "password";

// Set the source to the VideoCaptureCore object
VideoCapture1.IP_Camera_Source = settings;

Use the IPPreview or IPCapture mode to preview or capture video from the device.

VideoCaptureCoreX

Create the source settings object using the NDI source URL.

var ndiSettings = await NDISourceSettings.CreateAsync(VideoCapture1.GetContext(), null, "NDI URL");

Or use the NDI name instead of the URL.

var ndiSettings = await NDISourceSettings.CreateAsync(VideoCapture1.GetContext(), cbIPURL.Text, null);

Set the source to the VideoCaptureCoreX object.

VideoCapture1.Video_Source = ndiSettings;

Sample applications that use the NDI source
