.. -*- coding: utf-8; mode: rst -*- .. _pixfmt: ############# Image Formats ############# The V4L2 API was primarily designed for devices exchanging image data with applications. 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 ` ioctl. (The explanations here focus on video capturing and output, for overlay frame buffer formats see also :ref:`VIDIOC_G_FBUF `.) .. toctree:: :maxdepth: 1 pixfmt-002 pixfmt-003 pixfmt-004 colorspaces pixfmt-006 pixfmt-007 pixfmt-008 pixfmt-indexed pixfmt-rgb yuv-formats hsv-formats depth-formats pixfmt-013 sdr-formats tch-formats meta-formats pixfmt-reserved
