This sample demonstrates how to use the
+MediaCapture API to capture video, audio, and pictures from a capture device, such as a webcam.
+
+
Specifically, this sample covers:
+
+- Previewing video from a capture device, such as a webcam, connected to the computer.
+
- Capturing video from a capture device, such as a webcam, connected to the computer.
+
- Taking a picture from a capture device, such as a webcam, connected to the computer.
+
- Enumerating cameras connected to the computer.
- Adding a video effect to a video.
- Recording audio from a capture device connected to the computer.
+
+
For more information on capturing video in your app, see
+Quickstart: capturing a photo or video using the camera dialog and
+Quickstart: capturing video using the MediaCapture API.

Important
+
This sample uses the Media Extension feature of Windows 8 to add functionality to the Microsoft Media Foundation pipeline. A Media Extension consists of a hybrid object that implements both Component Object Model (COM) and Windows Runtime
+ interfaces. The COM interfaces interact with the Media Foundation pipeline. The Windows Runtime interfaces activate the component and interact with the Windows Store app.
+
+
In most situations, it is recommended that you use Visual C++ with Component Extensions (C++/CX ) to interact with the Windows Runtime. But in the case of hybrid components that implement both COM and Windows Runtime interfaces, such as Media
+ Extensions, this is not possible. C++/CX can only create Windows Runtime objects. So, for hybrid objects it is recommended that you use
+Windows Runtime C++ Template Library to interact with the Windows Runtime. Be aware that Windows Runtime C++ Template Library has limited support for implementing COM interfaces.
