+components horizontally by 2, storing 2 pixels in a container. The container
+is 32-bits for 8-bit formats, and 64-bits for 10+-bit formats.

+The packed YUYV formats with more than 8 bits per component are stored as four
+16-bit little-endian words. Each word's most significant bits contain one
+component, and the least significant bits are zero padding.
