The struct :c:type:`v4l2_pix_format` and 11struct :c:type:`v4l2_pix_format_mplane` structures define the 12format and layout of an image in memory. The former is used with the 13single-planar API, while the latter is used with the multi-planar 14version (see :ref:`planar-apis`). Image formats are negotiated with 15the :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` ioctl. (The explanations here 16focus on video capturing and output, for overlay frame buffer formats 17see also :ref:`VIDIOC_G_FBUF <VIDIOC_G_FBUF>`.) 18 19 20.. toctree:: 21 :maxdepth: 1 22 23 pixfmt-v4l2 24 pixfmt-v4l2-mplane 25 pixfmt-intro 26 pixfmt-indexed 27 pixfmt-rgb 28 pixfmt-bayer 29 yuv-formats 30 hsv-formats 31 depth-formats 32 pixfmt-compressed 33 sdr-formats 34 tch-formats 35 meta-formats 36 pixfmt-reserved 37 colorspaces 38 colorspaces-defs 39 colorspaces-details 40
