		/**
		* <p>Android YUV P010 format.</p>
		*
		* P010 is a 4:2:0 YCbCr semiplanar format comprised of a WxH Y plane
		* followed immediately by a Wx(H/2) CbCr plane. Each sample is
		* represented by a 16-bit little-endian value, with the lower 6 bits set
		* to zero.
		*
		* <p>This format assumes
		* <ul>
		* <li>an even height</li>
		* <li>a vertical stride equal to the height</li>
		* </ul>
		* </p>
		*
		* <pre> stride_in_bytes = stride * 2 </pre>
		* <pre> y_size = stride_in_bytes * height </pre>
		* <pre> cbcr_size = stride_in_bytes * (height / 2) </pre>
		* <pre> cb_offset = y_size </pre>
		* <pre> cr_offset = cb_offset + 2 </pre>
		*
		* <p>For example, the {@link android.media.Image} object can provide data
		* in this format from a {@link android.hardware.camera2.CameraDevice}
		* through a {@link android.media.ImageReader} object if this format is
		* supported by {@link android.hardware.camera2.CameraDevice}.</p>
