Getting Started --------------- -To fetch the sources, build and install: +Only build ``libcamera`` from scratch if you need custom behaviour or the latest features that have not yet reached ``apt`` repositories. +If you run ``Raspberry Pi OS Lite``, begin by installing the following packages: + .. code:: - git clone https://git.libcamera.org/libcamera/libcamera.git + sudo apt install -y python-pip git python3-jinja2 + +First, install the following ``libcamera`` dependencies: +.. code:: + + sudo apt install -y libboost-dev + sudo apt install -y libgnutls28-dev openssl libtiff-dev pybind11-dev + sudo apt install -y qtbase5-dev libqt5core5a libqt5widgets + sudo apt install -y meson cmake + sudo apt install -y python3-yaml python3-ply + sudo apt install -y libglib2.0-dev libgstreamer-plugins-base1.0-dev + +Now we're ready to build ``libcamera`` itself. + +Download a local copy of Raspberry Pi's fork of ``libcamera`` from GitHub, before building and installing freshly-build binary: + +.. code:: + + git clone https://github.com/raspberrypi/libcamera.git cd libcamera - meson setup build + meson setup build --buildtype=release -Dpipelines=rpi/vc4,rpi/pisp -Dipas=rpi/vc4,rpi/pisp -Dv4l2=true -Dgstreamer=enabled -Dtest=false -Dlc-compliance=disabled -Dcam=disabled -Dqcam=disabled -Ddocumentation=disabled -Dpycamera=enabled ninja -C build install +You can disable the ``gstreamer`` plugin by replacing ``-Dgstreamer=enabled`` with ``-Dgstreamer=disabled`` during the ``meson`` build configuration. +If you disable ``gstreamer``, there is no need to install the ``libglib2.0-dev`` and ``libgstreamer-plugins-base1.0-dev`` dependencies. + +On devices with 1GB of memory or less, the build may exceed available memory. Append the ``-j 1`` flag to ``ninja`` commands to limit the build to a single process. +This should prevent the build from exceeding available memory on devices like the Raspberry Pi Zero and the Raspberry Pi 3. + +``libcamera`` does not yet have a stable binary interface. Always build ``rpicam-apps`` after you build ``libcamera``. + +You can find more informations at `Raspberry Pi libcamera documentation`_ pages. + +.. _Raspberry Pi libcamera documentation: https://www.raspberrypi.com/documentation/computers/camera_software.html + Dependencies ~~~~~~~~~~~~ |
