CameraView

The CameraView provides the ability to connect to a camera, display a preview from the camera and take photos. The CameraView also offers features to support taking photos, controlling the flash, saving captured media to a file, and offering different hooks for events.

The following sections will incrementally build on how to use the CameraView in a .NET MAUI application. They rely on the use of a CameraViewModel. that will be set as the BindingContext of the example CameraViewPage.

Platform specific initialization

The CameraView is part of the CommunityToolkit.Maui.Camera nuget package. To first use the CameraView please refer to the Getting started section. The following platform specific setup is required.

The following permissions need to be added to the Platforms/Android/AndroidManifest.xml file:

<uses-permission android:name="android.permission.CAMERA" />

This should be added inside the <manifest> element. Below shows a more complete example:

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android">
    <application android:allowBackup="true" android:icon="@mipmap/appicon" android:roundIcon="@mipmap/appicon_round" android:supportsRtl="true" />

    <uses-permission android:name="android.permission.CAMERA" />

</manifest>

The following entries need to be added to the Platforms/iOS/Info.plist file:

<key>NSCameraUsageDescription</key>
<string>PROVIDE YOUR REASON HERE</string>

This should be added inside the <dict> element. Below shows a more complete example:

Basic usage

The CameraView can be added to a .NET MAUI application in the following way.

Including the XAML namespace

In order to use the toolkit in XAML the following xmlns needs to be added into your page or view:

xmlns:toolkit="http://schemas.microsoft.com/dotnet/2022/maui/toolkit"

Therefore the following:

<ContentPage
    x:Class="CommunityToolkit.Maui.Sample.Pages.MyPage"
    xmlns="http://schemas.microsoft.com/dotnet/2021/maui"
    xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml">

</ContentPage>

Would be modified to include the xmlns as follows:

<ContentPage
    x:Class="CommunityToolkit.Maui.Sample.Pages.MyPage"
    xmlns="http://schemas.microsoft.com/dotnet/2021/maui"
    xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
    xmlns:toolkit="http://schemas.microsoft.com/dotnet/2022/maui/toolkit">

</ContentPage>

<ContentPage
    x:Class="CommunityToolkit.Maui.Sample.Pages.CameraViewPage"
    xmlns="http://schemas.microsoft.com/dotnet/2021/maui"
    xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
    xmlns:toolkit="http://schemas.microsoft.com/dotnet/2022/maui/toolkit">
    
    <Grid ColumnDefinitions="*,*,*" RowDefinitions="*,30">
        <toolkit:CameraView 
            Grid.ColumnSpan="3" 
            Grid.Row="0" />
    </Grid>

</ContentPage>

The result will be a surface rendering the output of the default camera connected to the device.

Access the current camera

The SelectedCamera property provides the ability to access the currently selected camera.

The following example shows how to bind the SelectedCamera property from the CameraView to a property on the CameraViewModel with the same name (SelectedCamera).

<ContentPage
    x:Class="CommunityToolkit.Maui.Sample.Pages.CameraViewPage"
    xmlns="http://schemas.microsoft.com/dotnet/2021/maui"
    xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
    xmlns:toolkit="http://schemas.microsoft.com/dotnet/2022/maui/toolkit">
    
    <Grid ColumnDefinitions="*,*,*" RowDefinitions="*,30,30">
        <toolkit:CameraView 
            Grid.ColumnSpan="3" 
            Grid.Row="0" 
            SelectedCamera="{Binding SelectedCamera}" />
    </Grid>

</ContentPage>

Control Zoom

The SelectedCamera property provides both a MinimumZoomFactor and a MaximumZoomFactor property, these are read-only and provide developers with a programmatic way of determining what zoom can be applied to the current camera. In order to change the zoom on the current camera the CameraView provides the ZoomFactor property.

Note

If a value is provided outside of the MinimumZoomFactor and MaximumZoomFactor the CameraView will clamp the value to keep it within the bounds.

The following example shows how to add a Slider into the application and setup the following bindings:

Bind the Maximum property of the Slider to the MaximumZoomFactor of the SelectedCamera property.
Bind the Minimum property of the Slider to the MinimumZoomFactor of the SelectedCamera property.
Bind the Value property of the Slider to the CurrentZoom property on the CameraViewModel class.

The final change involves binding the ZoomFactor property of the CameraView to the CurrentZoom property on the CameraViewModel class.

    xmlns:toolkit="http://schemas.microsoft.com/dotnet/2022/maui/toolkit">
    
    <Grid ColumnDefinitions="*,*,*" RowDefinitions="*,30,30">
        <toolkit:CameraView 
            Grid.ColumnSpan="3" 
            Grid.Row="0"
            SelectedCamera="{Binding SelectedCamera}"
            ZoomFactor="{Binding CurrentZoom}" />

        <Slider 
            Grid.Column="0"
            Grid.Row="1"
            Value="{Binding CurrentZoom}"
            Maximum="{Binding SelectedCamera.MaximumZoomFactor, FallbackValue=1}"
            Minimum="{Binding SelectedCamera.MinimumZoomFactor, FallbackValue=1}"/>
    </Grid>

Camera Flash Mode

The CameraView provides the ability to programmatically change the flash mode on the device, the possible options are:

Off - the flash is off and will not be used.
On - the flash is on and will always be used.
Auto - the flash will automatically be used based on the lighting conditions.

The SelectedCamera property also provides the IsFlashSupported which makes it possible to determine whether the currently selected camera has a flash that can be controlled.

The following example shows how to add a Picker into the application and setup the following bindings:

Bind the IsVisible property of the Picker to the IsFlashSupported of the SelectedCamera property.
Bind the ItemsSource property of the Picker to the FlashModes property on the CameraViewModel class - a simple list of the possible values of the CameraFlashMode enum.
Bind the SelectedItem property of the Picker to the FlashMode property on the CameraViewModel class.

The final change involves binding the CameraFlashMode property of the CameraView to the FlashMode property on the CameraViewModel class.

            ItemsSource="{Binding FlashModes}"
            SelectedItem="{Binding FlashMode}" />
    </Grid>

ImageCaptureResolution

The CameraView provides the ability to programmatically change resolution for images captured from the current camera.

Note

This will not change the resolution displayed in the preview from the camera.

The SelectedCamera property also provides the SupportedResolutions which makes it possible to determine which resolutions the current camera supports.

The following example shows how to add a Picker into the application and setup the following bindings:

Bind the ItemsSource property of the Picker to the SupportedResolutions of the SelectedCamera property.
Bind the SelectedItem property of the Picker to the SelectedResolution property on the CameraViewModel class.

The final change involves binding the ImageCaptureResolution property of the CameraView to the SelectedResolution property on the CameraViewModel class.

CaptureImage

The CameraView provides the ability to programmatically trigger an image capture. This is possible through both the CaptureImage method or the CaptureImageCommand.

The following example shows how to add a Button into the application and setup the following bindings:

Bind the Command property of the Button to the CaptureImageCommand property on the CameraView.

            Grid.ColumnSpan="3" 
            Grid.Row="0"
            SelectedCamera="{Binding SelectedCamera}"
            ZoomFactor="{Binding CurrentZoom}"
            CameraFlashMode="{Binding FlashMode}" />

        <Slider 
            Grid.Column="0"
            Grid.Row="1"
            Value="{Binding CurrentZoom}"
            Maximum="{Binding SelectedCamera.MaximumZoomFactor, FallbackValue=1}"
            Minimum="{Binding SelectedCamera.MinimumZoomFactor, FallbackValue=1}"/>

        <Picker 
            Grid.Column="1"
            Grid.Row="1"
            Title="Flash"
            IsVisible="{Binding Path=SelectedCamera.IsFlashSupported, FallbackValue=false}"
            ItemsSource="{Binding FlashModes}"
            SelectedItem="{Binding FlashMode}" />

        <Picker 
            Grid.Column="2"
            Grid.Row="1"
            Title="Available Resolutions"
            ItemsSource="{Binding SelectedCamera.SupportedResolutions}"
            SelectedItem="{Binding SelectedResolution}" />

        <Button
            Grid.Column="0"
            Grid.Row="2"
            Command="{Binding CaptureImageCommand, Source={x:Reference Camera}}"
            Text="Capture Image" />
    </Grid>

</ContentPage>

Note

In order to use the image that has been captured the CameraView provides the MediaCaptured event.

The following example demonstrates how to use the CaptureImage method:

Note

The C# code below uses the Camera field defined above in XAML (<toolkit:CameraView x:Name="Camera" />)

async void HandleCaptureButtonTapped(object? sender, EventArgs e)
{
    try
    {
        // Use the Camera field defined above in XAML (`<toolkit:CameraView x:Name="Camera" />`)
        var captureImageCTS = new CancellationTokenSource(TimeSpan.FromSeconds(3));
        Stream stream = await Camera.CaptureImage(captureImageCTS.Token);
    }
    catch(Exception e)
    {
        // Handle Exception
        Trace.WriteLine(e);
    }
}

Video Recording

The CameraView provides the ability to record videos. This is possible through both the StartVideoRecording method or the StartVideoRecordingCommand.

The following example shows how to add a Button into the application and setup the following bindings:

Bind the Command property of the Button to the StartVideoRecordingCommand property on the CameraView.

            Grid.ColumnSpan="3" 
            Grid.Row="0"
            SelectedCamera="{Binding SelectedCamera}"
            ZoomFactor="{Binding CurrentZoom}"
            CameraFlashMode="{Binding FlashMode}" />

        <Slider 
            Grid.Column="0"
            Grid.Row="1"
            Value="{Binding CurrentZoom}"
            Maximum="{Binding SelectedCamera.MaximumZoomFactor, FallbackValue=1}"
            Minimum="{Binding SelectedCamera.MinimumZoomFactor, FallbackValue=1}"/>

        <Picker 
            Grid.Column="1"
            Grid.Row="1"
            Title="Flash"
            IsVisible="{Binding Path=SelectedCamera.IsFlashSupported, FallbackValue=false}"
            ItemsSource="{Binding FlashModes}"
            SelectedItem="{Binding FlashMode}" />

        <Picker 
            Grid.Column="2"
            Grid.Row="1"
            Title="Available Resolutions"
            ItemsSource="{Binding SelectedCamera.SupportedResolutions}"
            SelectedItem="{Binding SelectedResolution}" />

        <Button Clicked="StartCameraRecording"
                Text="StartVideoRecording" />

        <Button Command="{Binding StartVideoRecordingCommand, Source={x:Reference Camera}, x:DataType=toolkit:CameraView}"
                CommandParameter="{Binding Stream}"
                Text="StartVideoRecording" />

        <Button Command="{Binding StopVideoRecordingCommand, Source={x:Reference Camera}, x:DataType=toolkit:CameraView}"
                CommandParameter="{Binding Token}"
                Text="StopVideoRecording" />
    </Grid>

</ContentPage>

Note

You must provide a clean stream in order to record the video.

The following example demonstrates how to use the StartVideoRecording method:

Note

The C# code below uses the Camera field defined above in XAML (<toolkit:CameraView x:Name="Camera" />)

async void StartCameraRecordingWithCustomStream(object? sender, EventArgs e)
{
    using var threeSecondVideoRecordingStream = new FileStream("recording.mp4");
    await Camera.StartVideoRecording(stream, CancellationToken.None);

    await Task.Delay(TimeSpan.FromSeconds(3));
    
    await Camera.StopVideoRecording(CancellationToken.None);
    await FileSaver.SaveAsync("recording.mp4", threeSecondVideoRecordingStream);
}

In case you want to record a short video and record video in MemoryStream you can use the next overload of VideoRecording:

async void StartCameraRecording(object? sender, EventArgs e)
{
    await Camera.StartVideoRecording(CancellationToken.None);
    
    await Task.Delay(TimeSpan.FromSeconds(3));
    
    var threeSecondVideoRecordingStream = await Camera.StopVideoRecording(CancellationToken.None);
    await FileSaver.SaveAsync("recording.mp4", threeSecondVideoRecordingStream);
}

Start preview

The CameraView provides the ability to programmatically start the preview from the camera. This is possible through both the StartCameraPreview method or the StartCameraPreviewCommand.

The following example shows how to add a Button into the application and setup the following bindings:

Bind the Command property of the Button to the StartCameraPreviewCommand property on the CameraView.

        // Use the Camera field defined above in XAML (`<toolkit:CameraView x:Name="Camera" />`)
        await Camera.StartCameraPreview(startCameraPreviewTCS.Token);
    }
    catch(Exception e)
    {
        // Handle Exception
        Trace.WriteLine(e);
    }
}

The following example demonstrates how to use the StopCameraPreview method:

Note

The C# code below uses the Camera field defined above in XAML (<toolkit:CameraView x:Name="Camera" />)

void HandleStopCameraPreviewButtonTapped(object? sender, EventArgs e)
{

    try
    {
        // Use the Camera field defined above in XAML (`<toolkit:CameraView x:Name="Camera" />`)
        Camera.StopCameraPreview();
    }
    catch(Exception e)
    {
        // Handle Exception
        Trace.WriteLine(e);
    }
}
