What kind of UWP app to make for Windows camera filtering app?
To make a UWP app for filtering the Windows camera feed, you can create an app that utilizes the MediaCapture API and applies image processing filters to the camera feed. Here are some steps to get started:
- Create a new UWP project in Visual Studio.
- Add the
Windows.Media.Capture
namespace to your project. - Add a
CaptureElement
control to your app's user interface. This control will be used to display the camera feed. - Initialize the
MediaCapture
object and set itsVideoDeviceCharacteristic
property toVideoDeviceCharacteristic.AllStreamsIndependent
to enable video preview and processing. - Bind the
CaptureElement
control'sSource
property to theMediaCapture
object. - Add image processing filters to the camera feed by creating custom
IMediaExtension
classes and applying them to theMediaCapture
object.
Here's some sample code to get you started:
csharpusing Windows.Media.Capture;
using Windows.UI.Xaml.Controls;
// Initialize the MediaCapture object
MediaCapture mediaCapture = new MediaCapture();
await mediaCapture.InitializeAsync(new MediaCaptureInitializationSettings
{
VideoDeviceCharacteristic = VideoDeviceCharacteristic.AllStreamsIndependent
});
// Bind the CaptureElement control to the MediaCapture object
captureElement.Source = mediaCapture;
// Apply image processing filters to the camera feed
// Create a custom IMediaExtension class that implements the image processing filter
IMediaExtension filter = new MyImageFilter();
mediaCapture.VideoDeviceController.SetMediaStreamPropertiesAsync(MediaStreamType.VideoPreview, filter.GetProperties(MediaStreamType.VideoPreview, null));
In this code, the MediaCapture
object is initialized with the VideoDeviceCharacteristic.AllStreamsIndependent
property set to enable video preview and processing. The Source
property of the CaptureElement
control is then bound to the MediaCapture
object to display the camera feed. Finally, a custom image processing filter is applied to the camera feed by creating an IMediaExtension
class and setting it as the media stream properties for the video preview.
Note that you will need to create custom image processing filters to apply to the camera feed. The IMediaExtension
interface provides methods for setting and getting media stream properties, which can be used to apply image processing filters to the camera feed. You can find more information on creating custom media extensions in the Microsoft documentation.
