Each four bytes is two 25Y's, a Cb and a Cr. Each Y goes to one of the pixels, and the Cb and Cr 26belong to both pixels. As you can see, the Cr and Cb components have 27half the horizontal resolution of the Y component. ``V4L2_PIX_FMT_YUYV`` 28is known in the Windows environment as YUY2. 29 30**Byte Order.** 31Each cell is one byte. 32 33 34 35 36.. flat-table:: 37 :header-rows: 0 38 :stub-columns: 0 39 40 * - start + 0: 41 - Y'\ :sub:`00` 42 - Cb\ :sub:`00` 43 - Y'\ :sub:`01` 44 - Cr\ :sub:`00` 45 - Y'\ :sub:`02` 46 - Cb\ :sub:`01` 47 - Y'\ :sub:`03` 48 - Cr\ :sub:`01` 49 * - start + 8: 50 - Y'\ :sub:`10` 51 - Cb\ :sub:`10` 52 - Y'\ :sub:`11` 53 - Cr\ :sub:`10` 54 - Y'\ :sub:`12` 55 - Cb\ :sub:`11` 56 - Y'\ :sub:`13` 57 - Cr\ :sub:`11` 58 * - start + 16: 59 - Y'\ :sub:`20` 60 - Cb\ :sub:`20` 61 - Y'\ :sub:`21` 62 - Cr\ :sub:`20` 63 - Y'\ :sub:`22` 64 - Cb\ :sub:`21` 65 - Y'\ :sub:`23` 66 - Cr\ :sub:`21` 67 * - start + 24: 68 - Y'\ :sub:`30` 69 - Cb\ :sub:`30` 70 - Y'\ :sub:`31` 71 - Cr\ :sub:`30` 72 - Y'\ :sub:`32` 73 - Cb\ :sub:`31` 74 - Y'\ :sub:`33` 75 - Cr\ :sub:`31` 76 77 78**Color Sample Location:** 79 80 81 82.. flat-table:: 83 :header-rows: 0 84 :stub-columns: 0 85 86 * - 87 - 0 88 - 89 - 1 90 - 91 - 2 92 - 93 - 3 94 * - 0 95 - Y 96 - C 97 - Y 98 - 99 - Y 100 - C 101 - Y 102 * - 1 103 - Y 104 - C 105 - Y 106 - 107 - Y 108 - C 109 - Y 110 * - 2 111 - Y 112 - C 113 - Y 114 - 115 - Y 116 - C 117 - Y 118 * - 3 119 - Y 120 - C 121 - Y 122 - 123 - Y 124 - C 125 - Y 126
