The struct :c:type:`v4l2_pix_format` and +struct :c:type:`v4l2_pix_format_mplane` structures define the +format and layout of an image in memory. The former is used with the +single-planar API, while the latter is used with the multi-planar +version (see :ref:`planar-apis`). Image formats are negotiated with +the :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` ioctl. (The explanations here +focus on video capturing and output, for overlay frame buffer formats +see also :ref:`VIDIOC_G_FBUF <VIDIOC_G_FBUF>`.) + + +.. toctree:: + :maxdepth: 1 + + pixfmt-v4l2 + pixfmt-v4l2-mplane + pixfmt-intro + pixfmt-indexed + pixfmt-rgb + pixfmt-bayer + yuv-formats + hsv-formats + depth-formats + pixfmt-compressed + sdr-formats + tch-formats + meta-formats + pixfmt-reserved + colorspaces + colorspaces-defs + colorspaces-details |
