This object extends LuminanceSource around an array of YUV data returned the camera driver, with the option to crop to a rectangle within the full data. This can be used to exclude superfluous pixels around the perimeter and speed up decoding.

It works for any pixel format where the Y channel is planar and appears first, including YCbCr_420_SP and YCbCr_422_SP.-This object extends LuminanceSource around an array of YUV data returned　the camera driver, with the option to crop to a rectangle within the full data.
