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, Cb 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, Cb 94 - No 95 - Linear 96 * - V4L2_PIX_FMT_NV12MT 97 - 'TM12' 98 - 8 99 - 4:2:0 100 - Cb, Cr 101 - No 102 - 64x32 tiles 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 tiles 112 * - V4L2_PIX_FMT_P010 113 - 'P010' 114 - 10 115 - 4:2:0 116 - Cb, Cr 117 - Yes 118 - Linear 119 * - V4L2_PIX_FMT_P010_4L4 120 - 'T010' 121 - 10 122 - 4:2:0 123 - Cb, Cr 124 - Yes 125 - 4x4 tiles 126 * - V4L2_PIX_FMT_P012 127 - 'P012' 128 - 12 129 - 4:2:0 130 - Cb, Cr 131 - Yes 132 - Linear 133 * - V4L2_PIX_FMT_P012M 134 - 'PM12' 135 - 12 136 - 4:2:0 137 - Cb, Cr 138 - No 139 - Linear 140 * - V4L2_PIX_FMT_NV15 141 - 'NV15' 142 - 10 143 - 4:2:0 144 - Cb, Cr 145 - Yes 146 - Linear 147 * - V4L2_PIX_FMT_NV15_4L4 148 - 'VT15' 149 - 15 150 - 4:2:0 151 - Cb, Cr 152 - Yes 153 - 4x4 tiles 154 * - V4L2_PIX_FMT_MT2110T 155 - 'MT2T' 156 - 15 157 - 4:2:0 158 - Cb, Cr 159 - No 160 - 16x32 / 16x16 tiles tiled low bits 161 * - V4L2_PIX_FMT_MT2110R 162 - 'MT2R' 163 - 15 164 - 4:2:0 165 - Cb, Cr 166 - No 167 - 16x32 / 16x16 tiles raster low bits 168 * - V4L2_PIX_FMT_NV16 169 - 'NV16' 170 - 8 171 - 4:2:2 172 - Cb, Cr 173 - Yes 174 - Linear 175 * - V4L2_PIX_FMT_NV61 176 - 'NV61' 177 - 8 178 - 4:2:2 179 - Cr, Cb 180 - Yes 181 - Linear 182 * - V4L2_PIX_FMT_NV16M 183 - 'NM16' 184 - 8 185 - 4:2:2 186 - Cb, Cr 187 - No 188 - Linear 189 * - V4L2_PIX_FMT_NV61M 190 - 'NM61' 191 - 8 192 - 4:2:2 193 - Cr, Cb 194 - No 195 - Linear 196 * - V4L2_PIX_FMT_NV20 197 - 'NV20' 198 - 10 199 - 4:2:2 200 - Cb, Cr 201 - Yes 202 - Linear 203 * - V4L2_PIX_FMT_NV24 204 - 'NV24' 205 - 8 206 - 4:4:4 207 - Cb, Cr 208 - Yes 209 - Linear 210 * - V4L2_PIX_FMT_NV42 211 - 'NV42' 212 - 8 213 - 4:4:4 214 - Cr, Cb 215 - Yes 216 - Linear 217 218.. raw:: latex 219 220 \normalsize 221 222..

The 963luma plane comes first, and the order of the two chroma planes varies between 964formats. The two chroma planes always use the same subsampling. 965 966For memory contiguous formats, the number of padding pixels at the end of the 967chroma lines is identical to the padding of the luma lines. The chroma line 968stride (in bytes) is thus equal to the luma line stride divided by the 969horizontal subsampling factor. Vertical subsampling doesn't affect the line 970stride. 971 972For non-contiguous formats, no constraints are enforced by the format on the 973relationship between the luma and chroma line padding and stride. 974 975All components are stored with the same number of bits per component. 976 977``V4L2_PIX_FMT_P010_4L4`` stores pixels in 4x4 tiles, and stores tiles linearly 978in memory. The line stride must be aligned to multiple of 8 and image height to 979a multiple of 4. The layouts of the luma and chroma planes are identical. 980 981.. raw:: latex 982 983 \small 984 985.. tabularcolumns:: |p{5.0cm}|p{1.1cm}|p{1.5cm}|p{2.2cm}|p{1.2cm}|p{3.7cm}| 986 987.. flat-table:: Overview of Fully Planar YUV Formats 988 :header-rows: 1 989 :stub-columns: 0 990 991 * - Identifier 992 - Code 993 - Bits per component 994 - Subsampling 995 - Planes order [4]_ 996 - Contiguous [5]_ 997 998 * - V4L2_PIX_FMT_YUV410 999 - 'YUV9' 1000 - 8 1001 - 4:1:0 1002 - Y, Cb, Cr 1003 - Yes 1004 * - V4L2_PIX_FMT_YVU410 1005 - 'YVU9' 1006 - 8 1007 - 4:1:0 1008 - Y, Cr, Cb 1009 - Yes 1010 * - V4L2_PIX_FMT_YUV411P 1011 - '411P' 1012 - 8 1013 - 4:1:1 1014 - Y, Cb, Cr 1015 - Yes 1016 * - V4L2_PIX_FMT_YUV420M 1017 - 'YM12' 1018 - 8 1019 - 4:2:0 1020 - Y, Cb, Cr 1021 - No 1022 * - V4L2_PIX_FMT_YVU420M 1023 - 'YM21' 1024 - 8 1025 - 4:2:0 1026 - Y, Cr, Cb 1027 - No 1028 * - V4L2_PIX_FMT_YUV420 1029 - 'YU12' 1030 - 8 1031 - 4:2:0 1032 - Y, Cb, Cr 1033 - Yes 1034 * - V4L2_PIX_FMT_YVU420 1035 - 'YV12' 1036 - 8 1037 - 4:2:0 1038 - Y, Cr, Cb 1039 - Yes 1040 * - V4L2_PIX_FMT_YUV422P 1041 - '422P' 1042 - 8 1043 - 4:2:2 1044 - Y, Cb, Cr 1045 - Yes 1046 * - V4L2_PIX_FMT_YUV422M 1047 - 'YM16' 1048 - 8 1049 - 4:2:2 1050 - Y, Cb, Cr 1051 - No 1052 * - V4L2_PIX_FMT_YVU422M 1053 - 'YM61' 1054 - 8 1055 - 4:2:2 1056 - Y, Cr, Cb 1057 - No 1058 * - V4L2_PIX_FMT_YUV444M 1059 - 'YM24' 1060 - 8 1061 - 4:4:4 1062 - Y, Cb, Cr 1063 - No 1064 * - V4L2_PIX_FMT_YVU444M 1065 - 'YM42' 1066 - 8 1067 - 4:4:4 1068 - Y, Cr, Cb 1069 - No 1070 1071.. raw:: latex 1072 1073 \normalsize 1074 1075..
