The struct :c:type:`v4l2_pix_format` and 10 struct :c:type:`v4l2_pix_format_mplane` structures define the 11 format and layout of an image in memory. The former is used with the 12 single-planar API, while the latter is used with the multi-planar 13 version (see :ref:`planar-apis`). Image formats are negotiated with 14 the :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` ioctl. (The explanations here 15 focus on video capturing and output, for overlay frame buffer formats 16 see also :ref:`VIDIOC_G_FBUF <VIDIOC_G_FBUF>`.) 17 18 19 .. toctree:: 20 :maxdepth: 1 21 22 pixfmt-v4l2 23 pixfmt-v4l2-mplane 24 pixfmt-intro 25 pixfmt-indexed 26 pixfmt-rgb 27 pixfmt-bayer 28 yuv-formats 29 hsv-formats 30 depth-formats 31 pixfmt-compressed 32 sdr-formats 33 tch-formats 34 meta-formats 35 pixfmt-reserved 36 colorspaces 37 colorspaces-defs 38 colorspaces-details
