They 10exist in two variants: 11 12- Semi-planar formats use two planes. The first plane is the luma plane and 13 stores the Y components. The second plane is the chroma plane and stores the 14 Cb and Cr components interleaved. 15 16- Fully planar formats use three planes to store the Y, Cb and Cr components 17 separately. 18 19Within a plane, components are stored in pixel order, which may be linear or 20tiled. Padding may be supported at the end of the lines, and the line stride of 21the chroma planes may be constrained by the line stride of the luma plane. 22 23Some planar formats allow planes to be placed in independent memory locations. 24They are identified by an 'M' suffix in their name (such as in 25``V4L2_PIX_FMT_NV12M``). Those formats are intended to be used only in drivers 26and applications that support the multi-planar API, described in 27:ref:`planar-apis`. Unless explicitly documented as supporting non-contiguous 28planes, formats require the planes to follow each other immediately in memory. 29 30 31Semi-Planar YUV Formats 32======================= 33 34These formats are commonly referred to as NV formats (NV12, NV16, ...). They 35use two planes, and store the luma components in the first plane and the chroma 36components in the second plane. The Cb and Cr components are interleaved in the 37chroma plane, with Cb and Cr always stored in pairs. The chroma order is 38exposed as different formats. 39 40For memory contiguous formats, the number of padding pixels at the end of the 41chroma lines is identical to the padding of the luma lines. Without horizontal 42subsampling, the chroma line stride (in bytes) is thus equal to twice the luma 43line stride. With horizontal subsampling by 2, the chroma line stride is equal 44to the luma line stride. Vertical subsampling doesn't affect the line stride. 45 46For non-contiguous formats, no constraints are enforced by the format on the 47relationship between the luma and chroma line padding and stride. 48 49All components are stored with the same number of bits per component. 50 51.. raw:: latex 52 53 \footnotesize 54 55.. tabularcolumns:: |p{5.2cm}|p{1.0cm}|p{1.5cm}|p{1.9cm}|p{1.2cm}|p{1.8cm}|p{2.7cm}| 56 57.. flat-table:: Overview of Semi-Planar YUV Formats 58 :header-rows: 1 59 :stub-columns: 0 60 61 * - Identifier 62 - Code 63 - Bits per component 64 - Subsampling 65 - Chroma order [1]_ 66 - Contiguous [2]_ 67 - Tiling [3]_ 68 * - V4L2_PIX_FMT_NV12 69 - 'NV12' 70 - 8 71 - 4:2:0 72 - Cb, Cr 73 - Yes 74 - Linear 75 * - V4L2_PIX_FMT_NV21 76 - 'NV21' 77 - 8 78 - 4:2:0 79 - Cr, Cr 80 - Yes 81 - Linear 82 * - V4L2_PIX_FMT_NV12M 83 - 'NM12' 84 - 8 85 - 4:2:0 86 - Cb, Cr 87 - No 88 - Linear 89 * - V4L2_PIX_FMT_NV21M 90 - 'NM21' 91 - 8 92 - 4:2:0 93 - Cr, Cr 94 - No 95 - Linear 96 * - V4L2_PIX_FMT_NV12MT 97 - 'TM12' 98 - 8 99 - 4:2:0 100 - Cb, Cr 101 - No 102 - 64x32 macroblocks 103 104 Horizontal Z order 105 * - V4L2_PIX_FMT_NV12MT_16X16 106 - 'VM12' 107 - 8 108 - 4:2:2 109 - Cb, Cr 110 - No 111 - 16x16 macroblocks 112 * - V4L2_PIX_FMT_NV16 113 - 'NV16' 114 - 8 115 - 4:2:2 116 - Cb, Cr 117 - Yes 118 - Linear 119 * - V4L2_PIX_FMT_NV61 120 - 'NV61' 121 - 8 122 - 4:2:2 123 - Cr, Cr 124 - Yes 125 - Linear 126 * - V4L2_PIX_FMT_NV16M 127 - 'NM16' 128 - 8 129 - 4:2:2 130 - Cb, Cr 131 - No 132 - Linear 133 * - V4L2_PIX_FMT_NV61M 134 - 'NM61' 135 - 8 136 - 4:2:2 137 - Cr, Cr 138 - No 139 - Linear 140 * - V4L2_PIX_FMT_NV24 141 - 'NV24' 142 - 8 143 - 4:4:4 144 - Cb, Cr 145 - Yes 146 - Linear 147 * - V4L2_PIX_FMT_NV42 148 - 'NV42' 149 - 8 150 - 4:4:4 151 - Cr, Cr 152 - Yes 153 - Linear 154 155.. raw:: latex 156 157 \normalsize 158 159..
