Sample code

Select video source

1. Get a list of available video capture devices, and fill combo-box

foreach (var device in VideoCapture1.Video_CaptureDevices)

2. Create video source device settings

VideoCapture1.Video_CaptureDevice = new VideoCaptureSource(cbVideoInputDevice.Text);

3. Get a list of available video formats and frame rates, fill combo-box

var deviceItem = VideoCapture1.Video_CaptureDevices.First(device => device.Name == cbVideoInputDevice.Text);
if (deviceItem == null)

foreach (string format in deviceItem.VideoFormats)

foreach (string frameRate in deviceItem.VideoFrameRates)

4. Select the video format

VideoCapture1.Video_CaptureDevice.Format = cbVideoInputFormat.Text;

or automatically choose the best video format

VideoCapture1.Video_CaptureDevice.Format_UseBest = true;

5. Select the frame rate

VideoCapture1.Video_CaptureDevice.FrameRate = Convert.ToDouble(cbVideoFrameRate.Text);

6. Select needed video input (configure crossbar) if needed

Select audio source

1. Get a list of available audio capture devices, and fill combo-box

foreach (var device in VideoCapture1.Audio_CaptureDevices)

2. Create audio source device settings

VideoCapture1.Audio_CaptureDevice = new AudioCaptureSource(cbAudioInputDevice.Text);

3. Get a list of available audio formats, and fill combo-box

var deviceItem = VideoCapture1.Audio_CaptureDevices.FirstOrDefault(device => device.Name == cbAudioInputDevice.Text);

if (deviceItem != null)
foreach (string format in deviceItem.Formats)

2. Select the format

VideoCapture1.Audio_CaptureDevice.Format = cbAudioInputFormat.Text;

or automatically choose the best audio format

VideoCapture1.Audio_CaptureDevice.Format_UseBest = true;

3. Select input (line)

VideoCapture1.Audio_CaptureDevice.Line = cbAudioInputLine.Text;
