The YCbCrPixelLayout class is not recommended for determining pixel layout on Windows Phone 8. YCbCr data provided by GetPreviewBufferY(array<Byte>[]()[]) 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. |
