Important Note:
The YCbCrPixelLayout class is not recommended for determining pixel layout on Windows Phone 8. YCbCr data provided by GetPreviewBufferArgb32(Int32()) follows the NV12 or NV21 format, depending on the version of phone. Apps running on Windows Phone 8 should process YCbCr data according to the NV12 standard rather than use YCbCrPixelLayout to determine pixel the layout. Apps running on phones prior to Windows Phone 8 should process YCbCr data according to the NV21 standard.
