They 11exist in two variants: 12 13- Semi-planar formats use two planes. The first plane is the luma plane and 14 stores the Y components. The second plane is the chroma plane and stores the 15 Cb and Cr components interleaved. 16 17- Fully planar formats use three planes to store the Y, Cb and Cr components 18 separately. 19 20Within a plane, components are stored in pixel order, which may be linear or 21tiled. Padding may be supported at the end of the lines, and the line stride of 22the chroma planes may be constrained by the line stride of the luma plane. 23 24Some planar formats allow planes to be placed in independent memory locations. 25They are identified by an 'M' suffix in their name (such as in 26``V4L2_PIX_FMT_NV12M``). Those formats are intended to be used only in drivers 27and applications that support the multi-planar API, described in 28:ref:`planar-apis`. Unless explicitly documented as supporting non-contiguous 29planes, formats require the planes to follow each other immediately in memory. 30 31 32Semi-Planar YUV Formats 33======================= 34 35These formats are commonly referred to as NV formats (NV12, NV16, ...). They 36use two planes, and store the luma components in the first plane and the chroma 37components in the second plane. The Cb and Cr components are interleaved in the 38chroma plane, with Cb and Cr always stored in pairs. The chroma order is 39exposed as different formats. 40 41For memory contiguous formats, the number of padding pixels at the end of the 42chroma lines is identical to the padding of the luma lines. Without horizontal 43subsampling, the chroma line stride (in bytes) is thus equal to twice the luma 44line stride. With horizontal subsampling by 2, the chroma line stride is equal 45to the luma line stride. Vertical subsampling doesn't affect the line stride. 46 47For non-contiguous formats, no constraints are enforced by the format on the 48relationship between the luma and chroma line padding and stride. 49 50All components are stored with the same number of bits per component. 51 52.. raw:: latex 53 54 \footnotesize 55 56.. tabularcolumns:: |p{5.2cm}|p{1.0cm}|p{1.5cm}|p{1.9cm}|p{1.2cm}|p{1.8cm}|p{2.7cm}| 57 58.. flat-table:: Overview of Semi-Planar YUV Formats 59 :header-rows: 1 60 :stub-columns: 0 61 62 * - Identifier 63 - Code 64 - Bits per component 65 - Subsampling 66 - Chroma order [1]_ 67 - Contiguous [2]_ 68 - Tiling [3]_ 69 * - V4L2_PIX_FMT_NV12 70 - 'NV12' 71 - 8 72 - 4:2:0 73 - Cb, Cr 74 - Yes 75 - Linear 76 * - V4L2_PIX_FMT_NV21 77 - 'NV21' 78 - 8 79 - 4:2:0 80 - Cr, Cb 81 - Yes 82 - Linear 83 * - V4L2_PIX_FMT_NV12M 84 - 'NM12' 85 - 8 86 - 4:2:0 87 - Cb, Cr 88 - No 89 - Linear 90 * - V4L2_PIX_FMT_NV21M 91 - 'NM21' 92 - 8 93 - 4:2:0 94 - Cr, Cb 95 - No 96 - Linear 97 * - V4L2_PIX_FMT_NV12MT 98 - 'TM12' 99 - 8 100 - 4:2:0 101 - Cb, Cr 102 - No 103 - 64x32 tiles 104 105 Horizontal Z order 106 * - V4L2_PIX_FMT_NV12MT_16X16 107 - 'VM12' 108 - 8 109 - 4:2:2 110 - Cb, Cr 111 - No 112 - 16x16 tiles 113 * - V4L2_PIX_FMT_P010 114 - 'P010' 115 - 10 116 - 4:2:0 117 - Cb, Cr 118 - Yes 119 - Linear 120 * - V4L2_PIX_FMT_P010_4L4 121 - 'T010' 122 - 10 123 - 4:2:0 124 - Cb, Cr 125 - Yes 126 - 4x4 tiles 127 * - V4L2_PIX_FMT_P012 128 - 'P012' 129 - 12 130 - 4:2:0 131 - Cb, Cr 132 - Yes 133 - Linear 134 * - V4L2_PIX_FMT_P012M 135 - 'PM12' 136 - 12 137 - 4:2:0 138 - Cb, Cr 139 - No 140 - Linear 141 * - V4L2_PIX_FMT_NV15 142 - 'NV15' 143 - 10 144 - 4:2:0 145 - Cb, Cr 146 - Yes 147 - Linear 148 * - V4L2_PIX_FMT_NV15_4L4 149 - 'VT15' 150 - 15 151 - 4:2:0 152 - Cb, Cr 153 - Yes 154 - 4x4 tiles 155 * - V4L2_PIX_FMT_MT2110T 156 - 'MT2T' 157 - 15 158 - 4:2:0 159 - Cb, Cr 160 - No 161 - 16x32 / 16x16 tiles tiled low bits 162 * - V4L2_PIX_FMT_MT2110R 163 - 'MT2R' 164 - 15 165 - 4:2:0 166 - Cb, Cr 167 - No 168 - 16x32 / 16x16 tiles raster low bits 169 * - V4L2_PIX_FMT_NV16 170 - 'NV16' 171 - 8 172 - 4:2:2 173 - Cb, Cr 174 - Yes 175 - Linear 176 * - V4L2_PIX_FMT_NV61 177 - 'NV61' 178 - 8 179 - 4:2:2 180 - Cr, Cb 181 - Yes 182 - Linear 183 * - V4L2_PIX_FMT_NV16M 184 - 'NM16' 185 - 8 186 - 4:2:2 187 - Cb, Cr 188 - No 189 - Linear 190 * - V4L2_PIX_FMT_NV61M 191 - 'NM61' 192 - 8 193 - 4:2:2 194 - Cr, Cb 195 - No 196 - Linear 197 * - V4L2_PIX_FMT_NV20 198 - 'NV20' 199 - 10 200 - 4:2:2 201 - Cb, Cr 202 - Yes 203 - Linear 204 * - V4L2_PIX_FMT_NV24 205 - 'NV24' 206 - 8 207 - 4:4:4 208 - Cb, Cr 209 - Yes 210 - Linear 211 * - V4L2_PIX_FMT_NV42 212 - 'NV42' 213 - 8 214 - 4:4:4 215 - Cr, Cb 216 - Yes 217 - Linear 218 219.. raw:: latex 220 221 \normalsize 222 223..

The 964luma plane comes first, and the order of the two chroma planes varies between 965formats. The two chroma planes always use the same subsampling. 966 967For memory contiguous formats, the number of padding pixels at the end of the 968chroma lines is identical to the padding of the luma lines. The chroma line 969stride (in bytes) is thus equal to the luma line stride divided by the 970horizontal subsampling factor. Vertical subsampling doesn't affect the line 971stride. 972 973For non-contiguous formats, no constraints are enforced by the format on the 974relationship between the luma and chroma line padding and stride. 975 976All components are stored with the same number of bits per component. 977 978``V4L2_PIX_FMT_P010_4L4`` stores pixels in 4x4 tiles, and stores tiles linearly 979in memory. The line stride must be aligned to multiple of 8 and image height to 980a multiple of 4. The layouts of the luma and chroma planes are identical. 981 982.. raw:: latex 983 984 \small 985 986.. tabularcolumns:: |p{5.0cm}|p{1.1cm}|p{1.5cm}|p{2.2cm}|p{1.2cm}|p{3.7cm}| 987 988.. flat-table:: Overview of Fully Planar YUV Formats 989 :header-rows: 1 990 :stub-columns: 0 991 992 * - Identifier 993 - Code 994 - Bits per component 995 - Subsampling 996 - Planes order [4]_ 997 - Contiguous [5]_ 998 999 * - V4L2_PIX_FMT_YUV410 1000 - 'YUV9' 1001 - 8 1002 - 4:1:0 1003 - Y, Cb, Cr 1004 - Yes 1005 * - V4L2_PIX_FMT_YVU410 1006 - 'YVU9' 1007 - 8 1008 - 4:1:0 1009 - Y, Cr, Cb 1010 - Yes 1011 * - V4L2_PIX_FMT_YUV411P 1012 - '411P' 1013 - 8 1014 - 4:1:1 1015 - Y, Cb, Cr 1016 - Yes 1017 * - V4L2_PIX_FMT_YUV420M 1018 - 'YM12' 1019 - 8 1020 - 4:2:0 1021 - Y, Cb, Cr 1022 - No 1023 * - V4L2_PIX_FMT_YVU420M 1024 - 'YM21' 1025 - 8 1026 - 4:2:0 1027 - Y, Cr, Cb 1028 - No 1029 * - V4L2_PIX_FMT_YUV420 1030 - 'YU12' 1031 - 8 1032 - 4:2:0 1033 - Y, Cb, Cr 1034 - Yes 1035 * - V4L2_PIX_FMT_YVU420 1036 - 'YV12' 1037 - 8 1038 - 4:2:0 1039 - Y, Cr, Cb 1040 - Yes 1041 * - V4L2_PIX_FMT_YUV422P 1042 - '422P' 1043 - 8 1044 - 4:2:2 1045 - Y, Cb, Cr 1046 - Yes 1047 * - V4L2_PIX_FMT_YUV422M 1048 - 'YM16' 1049 - 8 1050 - 4:2:2 1051 - Y, Cb, Cr 1052 - No 1053 * - V4L2_PIX_FMT_YVU422M 1054 - 'YM61' 1055 - 8 1056 - 4:2:2 1057 - Y, Cr, Cb 1058 - No 1059 * - V4L2_PIX_FMT_YUV444M 1060 - 'YM24' 1061 - 8 1062 - 4:4:4 1063 - Y, Cb, Cr 1064 - No 1065 * - V4L2_PIX_FMT_YVU444M 1066 - 'YM42' 1067 - 8 1068 - 4:4:4 1069 - Y, Cr, Cb 1070 - No 1071 1072.. raw:: latex 1073 1074 \normalsize 1075 1076..
