Introduction

Webcam is a WPF user control that uses the Expression Encoder SDK to enable easy display of webcam video in a WPF application.

Features

Webcam has the following features,

  • displays webcam video in a WPF application,
  • enables saving of webcam video (in .wmv format),
  • enables saving of snapshots of webcam preview.

Requirements

NB: There are two versions of Expression Encoder; the free and paid version (Expression Encoder Pro). Webcam can be used with either version.

In the code sample the audio and video devices are listed using the EncoderDevices.FindDevices() method. The EncoderDevices class is found in the Microsoft.Expression.Encoder.Devices namespace, so when using the webcam user control in your project ensure that you have installed Expression Encoder and added a reference to Microsoft.Expression.Encoder.dll. You can do this by right-clicking your project, selecting Add Reference from the context menu, and selecting Microsoft.Expression.Encoder in the Assemblies > Extensions section of the Reference Manager dialog box.

NB: When using Microsoft.Expression.Encoder.dll and WebcamControl.dll in your project ensure that the project build platform is set to x86.

Webcam

The following is the XAML markup for the user control,

<UserControl x:Class="Webcam" 
             xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" 
             xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"              
             xmlns:d="http://schemas.microsoft.com/expression/blend/2008" 
             xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
             xmlns:wf="clr-namespace:System.Windows.Forms;assembly=System.Windows.Forms"
             MinHeight="100" MinWidth="100"
             mc:Ignorable="d">
    <Grid>
        <WindowsFormsHost Name="WinFormsHost" Margin="0" Background="{x:Null}">
            <wf:Panel x:Name="WebcamPanel"/>
        </WindowsFormsHost>
    </Grid>
</UserControl>

To display video from a webcam the user control makes use of the LiveJob class, which is in the Microsoft.Expression.Encoder.Live namespace. LiveJob expose routines for encoding video and audio from a live source such as a webcam. The webcam video is displayed in a WinForms Panel which is hosted in a WindowsFormsHost.

''' <summary>
''' Displays webcam video.
''' </summary>
Public Sub StartPreview()
    Try
        If (_videoDevice IsNot Nothing) Then
            StopRecording()
            StopCapture()

            job = New LiveJob
            Dim frameDuration As Long = CLng(_frameRate * Math.Pow(10, 7))

            deviceSource = job.AddDeviceSource(_videoDevice, _audioDevice)
            deviceSource.PickBestVideoFormat(FrameSize, frameDuration)
            deviceSource.PreviewWindow = New PreviewWindow(New HandleRef(WebcamPanel, WebcamPanel.Handle))

            job.OutputFormat.VideoProfile = New AdvancedVC1VideoProfile
            job.OutputFormat.VideoProfile.Size = FrameSize
            job.OutputFormat.VideoProfile.FrameRate = FrameRate

            job.ActivateSource(deviceSource)

            isPreviewing = True
        End If
    Catch ex As Microsoft.Expression.Encoder.SystemErrorException
        Throw New Microsoft.Expression.Encoder.SystemErrorException
    End Try
End Sub

The LiveJob object is used to save webcam videos using the LiveJob.StartEncoding() method.

''' <summary>
''' Starts the recording of webcam images to a video file.
''' </summary>
Public Sub StartRecording()
    Dim vidDir As String = CType(GetValue(VideoDirectoryProperty), String)

    If (vidDir = String.Empty) Then
        Throw New DirectoryNotFoundException("Video directory has not been specified")
        Exit Sub
    ElseIf (Not Directory.Exists(vidDir)) Then
        Throw New DirectoryNotFoundException("The specified video directory does not exist")
        Exit Sub
    End If

    If (job IsNot Nothing AndAlso isPreviewing) Then
        StopRecording()

        Dim filePath As String = Path.Combine(vidDir, "Webcam " & TimeStamp() & ".wmv")
        Dim fileArcvFormat As New FileArchivePublishFormat(filePath)

        job.PublishFormats.Clear()
        job.PublishFormats.Add(fileArcvFormat)
        job.StartEncoding()

        SetValue(IsRecordingPropertyKey, True)
    End If
End Sub

A snapshot of a webcam video is actually just a snapshot of the WinForms Panel,

''' <summary>
''' Takes a snapshot of an webcam image.
''' The size of the image will be equal to the size of the control.
''' </summary>
Public Sub TakeSnapshot()
    Dim imgDir As String = CType(GetValue(ImageDirectoryProperty), String)

    If (imgDir = String.Empty) Then
        Throw New DirectoryNotFoundException("Image directory has not been specified")
        Exit Sub
    ElseIf (Not Directory.Exists(imgDir)) Then
        Throw New DirectoryNotFoundException("The specified image directory does not exist")
        Exit Sub
    End If

    If (job IsNot Nothing AndAlso isPreviewing) Then
        Dim panelWidth As Integer = WebcamPanel.Width
        Dim panelHeight As Integer = WebcamPanel.Height
        Dim imgFormat As ImageFormat = CType(GetValue(SnapshotFormatProperty), ImageFormat)
        Dim filePath As String = Path.Combine(imgDir, "Snapshot " & TimeStamp() & "." & imgFormat.ToString)
        Dim pnt As Point = WebcamPanel.PointToScreen(New Point(WebcamPanel.ClientRectangle.X, WebcamPanel.ClientRectangle.Y))

        Using bmp As New Bitmap(panelWidth, panelHeight)
            Using grx As Graphics = Graphics.FromImage(bmp)
                grx.CopyFromScreen(pnt, Point.Empty, New Size(panelWidth, panelHeight))
            End Using
            bmp.Save(filePath, imgFormat)
        End Using
    End If
End Sub

GeneralRemote Streaming Question [modified] PinmemberPaulReis9-Jul-12 10:42 
Say I build a windows app that captures a users webcam (video and audio). Can I then stream their webcam (live) to a remote windows encoder server to then publish as a broadcast for people to view? I see in encoder 4 you can connect your webcam and stream it but they (encoder and webcam) have to be on the same machine. I was hoping to build something so I can have a couple remote users stream their webcam to my encoder server to then broadcast as a live event. like ustream and some other services out their. I'd like to build something basic myself.
