8. At the top of the Form1.vb file, add the following to the using directives
already in the class:

Imports Viscomsoft.VideoCapture

9.  The following code bit presents the video capture sdk initialization:
 

Public Class Form1

Public _capture As VideoCapture

Public _devices As Devices

Private Sub Form1_Load(sender As System.Object, e As System.EventArgs) Handles MyBase.Load

_capture = New VideoCapture()

_capture.Initialize()

_devices = New Devices()

_devices.Refresh()
 

10.  double click Form1.vb in the Solution Explorer and Drag the PictureBox to form.

11.  After _devices.Refresh() add the following code use PictureBox for preview window, set the Preview Mode, selected first video device and audio device and use first video resolution. If the Start() return 1 , it mean successful for preview video.
 

_capture.Window = PictureBox1.Handle

_capture.Mode = VideoCapture.CaptureMode.Preview

_capture.VideoDevice = _devices.VideoDevices.Item(0)

_capture.VideoDevice.SelectedResolution = _capture.VideoDevice.VideoResolutions.Item(0)

_capture.AudioDevice = _devices.AudioDevices.Item(0)

Dim iResult As Integer = _capture.Start()

12.  double click Form1.vb in the Solution Explorer and Drag the two button to form . For button1, In the Properties window, change the Text to "Capture to MP4"

_capture.OutputFile = "c:\temp\test1.mp4"

Dim audiodevice As AudioDevice = _devices.AudioDevices.Item(0)

_capture.AudioDevice = audiodevice

Dim lstbitrates As New Generic.List(Of Integer)

lstbitrates = _capture.Encoder.getSupportedAudioBitrates(audiodevice.AudioSamplingRates.Item(0).SampleRate, audiodevice.AudioSamplingRates.Item(0).Channels)

_capture.Encoder.AudioBitrate = lstbitrates.Item(0)

_capture.VideoDevice = _devices.VideoDevices.Item(0)

_capture.Encoder.VideoBitrate = 1000000

_capture.VideoDevice.SelectedResolution = _capture.VideoDevice.VideoResolutions.Item(0)

Dim iResult As Integer = _capture.Start()

14.  In button2 click event, add the following code.
 

_capture.Stop()

15.  Press F5 to Run the project, click Capture to MP4 video, then click Stop button to stop the capturing.
