Automatically open the rear camera on a windows 8 tablet using EasyWebCam in c#

I'm currently putting together a little project in c# designed to be used on Windows based tablets.

I have integrated the open source code available from http://easywebcam.codeplex.com/ to run the tablets camera. However, when you click the start button, it asks you to choose between the front or rear camera and as it is being used on a touch screen tablet, it's a bit on the fiddly side.

Does anyone know of a way of either adding a button to choose between the cameras or, better still, a way of automatically selecting the rear camera?

For Windows Store apps, a list of video capture device ids can be returned from DeviceInformation.FindAllAsync(DeviceClass.VideoCapture). See the Device enumeration sample for details.

Then you can set MediaCaptureInitializationSettings.VideoDeviceId and use it to initialize a capture session. Note however, this only supports UI-less capture. You cannot customize the selection in the CameraCaptureUI dialog.

For Desktop apps, a list of video capture device monikers can be returned from the device numerator (see How To Get A List Of Available Video Capture Devices for an example). Then you can plug the desired device moniker in your filter graph via IFilterGraph::AddFilter.
