WPF media kit camera orientation not working properly

I am developing a camera application for tablet PC running Windows 8.1 using wpf mediakit. I am using VideoCapture for this,

<Controls:VideoCaptureElement 
                    FPS="30"
                    x:Name="videoElement" Stretch="UniformToFill" 
                    HorizontalAlignment="Center"

                    VerticalAlignment="Center"
                    Height="Auto"
                    Width="Auto"
                    Margin="0, 0, 0, 0"
                    EnableSampleGrabbing="True"
                    Visibility="Visible"
                    UseYuv="False"
                    UseStillPin="False"
                    UnloadedBehavior="Close" >
                    <Controls:VideoCaptureElement.LayoutTransform>
                        <RotateTransform Angle="0" />
                    </Controls:VideoCaptureElement.LayoutTransform>
                </Controls:VideoCaptureElement>

The problem is that, when I change the orientation, the camera is not changing accordingly.

ie, If I am in a portrait view, the camera preview will be flipped.

How can I rotate the preview whenever the user changes the orientation ?
