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_4L4 141 - 'VT15' 142 - 15 143 - 4:2:0 144 - Cb, Cr 145 - Yes 146 - 4x4 tiles 147 * - V4L2_PIX_FMT_NV16 148 - 'NV16' 149 - 8 150 - 4:2:2 151 - Cb, Cr 152 - Yes 153 - Linear 154 * - V4L2_PIX_FMT_NV61 155 - 'NV61' 156 - 8 157 - 4:2:2 158 - Cr, Cb 159 - Yes 160 - Linear 161 * - V4L2_PIX_FMT_NV16M 162 - 'NM16' 163 - 8 164 - 4:2:2 165 - Cb, Cr 166 - No 167 - Linear 168 * - V4L2_PIX_FMT_NV61M 169 - 'NM61' 170 - 8 171 - 4:2:2 172 - Cr, Cb 173 - No 174 - Linear 175 * - V4L2_PIX_FMT_NV24 176 - 'NV24' 177 - 8 178 - 4:4:4 179 - Cb, Cr 180 - Yes 181 - Linear 182 * - V4L2_PIX_FMT_NV42 183 - 'NV42' 184 - 8 185 - 4:4:4 186 - Cr, Cb 187 - Yes 188 - Linear 189 190.. raw:: latex 191 192 \normalsize 193 194..

The 704luma plane comes first, and the order of the two chroma planes varies between 705formats. The two chroma planes always use the same subsampling. 706 707For memory contiguous formats, the number of padding pixels at the end of the 708chroma lines is identical to the padding of the luma lines. The chroma line 709stride (in bytes) is thus equal to the luma line stride divided by the 710horizontal subsampling factor. Vertical subsampling doesn't affect the line 711stride. 712 713For non-contiguous formats, no constraints are enforced by the format on the 714relationship between the luma and chroma line padding and stride. 715 716All components are stored with the same number of bits per component. 717 718``V4L2_PIX_FMT_P010_4L4`` stores pixels in 4x4 tiles, and stores tiles linearly 719in memory. The line stride must be aligned to multiple of 8 and image height to 720a multiple of 4. The layouts of the luma and chroma planes are identical. 721 722.. raw:: latex 723 724 \small 725 726.. tabularcolumns:: |p{5.0cm}|p{1.1cm}|p{1.5cm}|p{2.2cm}|p{1.2cm}|p{3.7cm}| 727 728.. flat-table:: Overview of Fully Planar YUV Formats 729 :header-rows: 1 730 :stub-columns: 0 731 732 * - Identifier 733 - Code 734 - Bits per component 735 - Subsampling 736 - Planes order [4]_ 737 - Contiguous [5]_ 738 739 * - V4L2_PIX_FMT_YUV410 740 - 'YUV9' 741 - 8 742 - 4:1:0 743 - Y, Cb, Cr 744 - Yes 745 * - V4L2_PIX_FMT_YVU410 746 - 'YVU9' 747 - 8 748 - 4:1:0 749 - Y, Cr, Cb 750 - Yes 751 * - V4L2_PIX_FMT_YUV411P 752 - '411P' 753 - 8 754 - 4:1:1 755 - Y, Cb, Cr 756 - Yes 757 * - V4L2_PIX_FMT_YUV420M 758 - 'YM12' 759 - 8 760 - 4:2:0 761 - Y, Cb, Cr 762 - No 763 * - V4L2_PIX_FMT_YVU420M 764 - 'YM21' 765 - 8 766 - 4:2:0 767 - Y, Cr, Cb 768 - No 769 * - V4L2_PIX_FMT_YUV420 770 - 'YU12' 771 - 8 772 - 4:2:0 773 - Y, Cb, Cr 774 - Yes 775 * - V4L2_PIX_FMT_YVU420 776 - 'YV12' 777 - 8 778 - 4:2:0 779 - Y, Cr, Cb 780 - Yes 781 * - V4L2_PIX_FMT_YUV422P 782 - '422P' 783 - 8 784 - 4:2:2 785 - Y, Cb, Cr 786 - Yes 787 * - V4L2_PIX_FMT_YUV422M 788 - 'YM16' 789 - 8 790 - 4:2:2 791 - Y, Cb, Cr 792 - No 793 * - V4L2_PIX_FMT_YVU422M 794 - 'YM61' 795 - 8 796 - 4:2:2 797 - Y, Cr, Cb 798 - No 799 * - V4L2_PIX_FMT_YUV444M 800 - 'YM24' 801 - 8 802 - 4:4:4 803 - Y, Cb, Cr 804 - No 805 * - V4L2_PIX_FMT_YVU444M 806 - 'YM42' 807 - 8 808 - 4:4:4 809 - Y, Cr, Cb 810 - No 811 812.. raw:: latex 813 814 \normalsize 815 816..
