How to get accessible camera resolutions? - silverlight

Question

I would like to ask, how it is possible to get all accessible camera resolutions in Windows Phone 8.1 app (for both silverlight and WinRT). I wanted to use:
Windows.Phone.Media.Capture.PhotoCaptureDevice.GetAvailableCaptureResolutions(
Windows.Phone.Media.Capture.CameraSensorLocation.Back);
But I am getting message that namespace Windows.Phone.Media.Capture is obsolete and may not be supported from next version of Windows Phone starting with Windows Phone Blue and that I should use Windows.Media.Capture instead. However Windows.Media.Capture does not allow me to get accessible camera resolutions, so I would like to ask, how to solve this.
Thank you.

It can be done like this:
First let's define method to get Device ID which will be used to take a photo:
private static async Task<DeviceInformation> GetCameraID(Windows.Devices.Enumeration.Panel desiredCamera)
{
DeviceInformation deviceID = (await DeviceInformation.FindAllAsync(DeviceClass.VideoCapture))
.FirstOrDefault(x => x.EnclosureLocation != null && x.EnclosureLocation.Panel == desiredCamera);
if (deviceID != null) return deviceID;
else throw new Exception(string.Format("Camera of type {0} doesn't exist.", desiredCamera));
}
Then after we initialize the camera - we can read the resolutions like this:
private async void InitCameraBtn_Click(object sender, RoutedEventArgs e)
{
var cameraID = await GetCameraID(Windows.Devices.Enumeration.Panel.Back);
captureManager = new MediaCapture();
await captureManager.InitializeAsync(new MediaCaptureInitializationSettings
{
StreamingCaptureMode = StreamingCaptureMode.Video,
PhotoCaptureSource = PhotoCaptureSource.VideoPreview,
AudioDeviceId = string.Empty,
VideoDeviceId = cameraID.Id
});
// Get resolutions
var resolutions = captureManager.VideoDeviceController.GetAvailableMediaStreamProperties(MediaStreamType.Photo).Select(x => x as VideoEncodingProperties).ToList();
// get width and height:
uint width = resolutions[0].Width;
uint height = resolutions[0].Height;
}
