This article provides an example app which is intended to be used as a template for applying filters to a real-time video with the ability to record video with the filters applied. The article will also describe key sections of code that are requirements for creating your own version of this app.

Enter article metadata as described below. Note that this template can be placed anywhere in the article. Do not remove parameters that you do not use

Introduction

With the introduction of universal apps and WinRT for Windows Phone 8.1, the Silverlight/WP8.0 method of accessing the camera has changed. Within the latest Nokia Imaging SDK is a IImageProvider called CameraPreviewImageSource which allows you to process frames from a video stream before capturing a final image to process. However, unless you were to provide your own video encoder, you cannot record the video being output by the CameraPreviewImageSource.

WinRT provides a MediaCapture class which provides video preview, image capture, and video record capabilities. The preview can be output to a new XAML class called a CaptureElement. There is no traditional way to apply the Nokia Imaging SDK to the preview (or record) output of the MediaCapture class. However, the MediaCapture class will accept Media Foundation Transforms through the AddEffectAsync method. This article will describe the key sections of code that are required to add a Media Foundation Transform to the app and how to incorporate the Nokia Imaging SDk into it.

Many parts of this app were inspired by or even pulled directly from code provided by other developers on this site.
