Output

**Prerequisites:** * Windows computer with a webcam installed * PowerShell installed on the computer * Webcam drivers installed and updated **Steps:** 1. **Create a new PowerShell script:** Open the Windows PowerShell ISE (Integrated Scripting Environment) or any PowerShell compatible text editor. 2. **Import the Multimedia module:** To access webcam functionality, import the Multimedia module using the following command: 

1
Import-Module Multimedia
3. **List available webcams:** Use the `Get-CimInstance` cmdlet to list the available webcams. This command will return a list of CIM (Common Information Model) instances representing the webcams. 
1
2
3
Get-CimInstance -ClassName Win32_VideoController | 
    Where-Object { $_.PNPDeviceID -like '*webcam*' } |
    Select-Object Name, PnpDeviceID
4. **Select the desired webcam:** Choose the index of the webcam you want to access from the output of the previous command. 5. **Create a VideoControl object:** Use the `New-Object` cmdlet to create a VideoControl object. The object represents the webcam and provides access to its video properties and methods. 
1
2
3
$webcam = New-Object System.Windows.Media.VideoCaptureDevice(
    'pnpdevid:' + $webcamID     # Replace $webcamID with the device ID of the desired webcam
)
6. **Start the webcam:** Start the webcam video feed using the `Start` method of the VideoControl object. 
1
$webcam.Start()
7. **Display the video feed:** To display the webcam video feed, you can create a video player using the `GetNativeVideoControl` method of the VideoControl object. This method returns a Windows Media Player object that you can use to show the video. 
1
2
$mediaPlayer = $webcam.GetNativeVideoControl()
$mediaPlayer.Visible = $true
8. **Stop the video feed:** When you are done viewing the video feed, stop it and release the resources using the `Stop` and `Dispose` methods of the VideoControl object. 
1
2
$webcam.Stop()
$webcam.Dispose()

$webcam.Start()

$mediaPlayer = $webcam.GetNativeVideoControl()
$mediaPlayer.Visible = $true

# Run the script until the user presses a key
Until ([Console]::ReadKey())

# Stop the webcam and release resources
$webcam.Stop()

**Requirements:** * PowerShell 5.1 or later * Microsoft.WindowsCamera module (optional) **Steps:** **1. Install the Microsoft.WindowsCamera Module (Optional):** This module provides additional functionality for working with webcams and is recommended for advanced scenarios. Run the following command in PowerShell: 

1
Install-Module -Name Microsoft.WindowsCamera
**2. Get a List of Webcam Devices:** Use the `Get-WmiObject` cmdlet to list all webcam devices connected to the computer. Run the following command: 
1
Get-WmiObject -Class Win32_VideoController | Where-Object {$_.DriverDesc -like "*Webcam*"}
**3. Select a Webcam Device:** From the list, select the device whose video feed you want to access by copying its `Name` property. **4. Access the Video Feed:** To access the video feed using raw DirectShow COM API (DirectShowLib library):

Add-Type -AssemblyName C:\Windows\System32\DirectShowLib.dll

$filter = "Name = '$WebcamName'"
$webcam = Get-WmiObject -Class Win32_VideoController -Filter $filter
$dev = New-Object -ComObject "DirectShowLib.DsDevice"
$dev.SetFilter($webcam.Name)
$cap = New-Object -ComObject "DirectShowLib.CaptureGraphBuilder2"
$cap.SetFiltergraph($dev.Moniker)
$cap.RenderStream($cap.FindInterface("IAMVideoControl", "VideoOutput0"))
$cap.Run()
To access the video feed using the Microsoft.WindowsCamera module (if installed): 
1
2
$webcam = Get-WindowsCamera
$stream = $webcam.OpenStream()
**5. Display the Video Feed:** The video feed can be displayed using various methods. Here's an example using Windows Forms:

# Using Windows Forms
$form = New-Object System.Windows.Forms.Form
$videoPanel = New-Object System.Windows.Forms.Panel -Property @{Size = [System.Drawing.Size]::new(640, 480)}
$videoPanel.Location = [System.Drawing.Point]::new(0, 0)
$form.Controls.Add($videoPanel)

if ($stream) {
    $videoViewer = New-Object Microsoft.WindowsCamera.CameraCaptureUISurface
    $videoViewer.CameraStream = $stream
    $videoPanel.Controls.Add($videoViewer)
} else {
    $label = New-Object System.Windows.Forms.Label -Property @{Location = [System.Drawing.Point]::new(0, 0), Text = "Unable to open webcam feed.\nEither grant access or install the Microsoft.WindowsCamera module."}
    $videoPanel.Controls.Add($label)
}

$form.ShowDialog() | Out-Null
**6. Stop the Video Feed:** Call the `Stop` method of the `CaptureGraphBuilder2` object or the `Dispose()` method of the `CameraCaptureUISurface` object to stop the video stream. **Example:**

2
$cap.Stop()
$videoViewer.Dispose()
