The first plane - contains interleaved JPEG and UYVY image data, followed by meta - data in form of an array of offsets to the UYVY data blocks. The - actual pointer array follows immediately the interleaved JPEG/UYVY - data, the number of entries in this array equals the height of the - UYVY image. Each entry is a 4-byte unsigned integer in big endian - order and it's an offset to a single pixel line of the UYVY image. - The first plane can start either with JPEG or UYVY data chunk. The - size of a single UYVY block equals the UYVY image's width - multiplied by 2. The size of a JPEG chunk depends on the image and - can vary with each line. - - The second plane, at an offset of 4084 bytes, contains a 4-byte - offset to the pointer array in the first plane. This offset is - followed by a 4-byte value indicating size of the pointer array. - All numbers in the second plane are also in big endian order. - Remaining data in the second plane is undefined. The information - in the second plane allows to easily find location of the pointer - array, which can be different for each frame. The size of the - pointer array is constant for given UYVY image height. - - In order to extract UYVY and JPEG frames an application can - initially set a data pointer to the start of first plane and then - add an offset from the first entry of the pointers table. Such a - pointer indicates start of an UYVY image pixel line. Whole UYVY - line can be copied to a separate buffer. These steps should be - repeated for each line, i.e. the number of entries in the pointer - array. Anything what's in between the UYVY lines is JPEG data and - should be concatenated to form the JPEG stream. - * .. _V4L2-PIX-FMT-MT21C: - - - ``V4L2_PIX_FMT_MT21C`` - - 'MT21' - - Compressed two-planar YVU420 format used by Mediatek MT8173. - The compression is lossless. - It is an opaque intermediate format and the MDP hardware must be - used to convert ``V4L2_PIX_FMT_MT21C`` to ``V4L2_PIX_FMT_NV12M``, - ``V4L2_PIX_FMT_YUV420M`` or ``V4L2_PIX_FMT_YVU420``. - * .. _V4L2-PIX-FMT-SUNXI-TILED-NV12: - - - ``V4L2_PIX_FMT_SUNXI_TILED_NV12`` - - 'ST12' - - Two-planar NV12-based format used by the video engine found on Allwinner - (codenamed sunxi) platforms, with 32x32 tiles for the luminance plane - and 32x64 tiles for the chrominance plane. The data in each tile is - stored in linear order, within the tile bounds. Each tile follows the - previous one linearly in memory (from left to right, top to bottom). - - The associated buffer dimensions are aligned to match an integer number - of tiles, resulting in 32-aligned resolutions for the luminance plane - and 16-aligned resolutions for the chrominance plane (with 2x2 - subsampling). - -.. tabularcolumns:: |p{6.6cm}|p{2.2cm}|p{8.7cm}| - -.. _format-flags: - -.. flat-table:: Format Flags - :header-rows: 0 - :stub-columns: 0 - :widths: 3 1 4 - - * - ``V4L2_PIX_FMT_FLAG_PREMUL_ALPHA`` - - 0x00000001 - - The color values are premultiplied by the alpha channel value. For - example, if a light blue pixel with 50% transparency was described - by RGBA values (128, 192, 255, 128), the same pixel described with - premultiplied colors would be described by RGBA values (64, 96, - 128, 128) |
