Getting Started

To fetch the sources, build and install:

git clone git://linuxtv.org/libcamera.git
cd libcamera
meson build
ninja -C build install

Dependencies

The following Debian/Ubuntu packages are required for building libcamera. Other distributions may have differing package names:

A C++ toolchain: [required]
Either {g++, clang}
Meson Build system: [required]

meson (>= 0.51) ninja-build pkg-config

If your distribution doesn’t provide a recent enough version of meson, you can install or upgrade it using pip3.

pip3 install --user meson
pip3 install --user --upgrade meson
for the libcamera core: [required]
python3-yaml
for IPA module signing: [required]
libgnutls28-dev openssl
for the Raspberry Pi IPA: [optional]

libboost-dev

Support for Raspberry Pi can be disabled through the meson
‘pipelines’ option to avoid this dependency.
for device hotplug enumeration: [optional]
libudev-dev
for documentation: [optional]
python3-sphinx doxygen graphviz
for gstreamer: [optional]
libgstreamer1.0-dev libgstreamer-plugins-base1.0-dev
for qcam: [optional]
qtbase5-dev libqt5core5a libqt5gui5 libqt5widgets5 qttools5-dev-tools libtiff-dev

Using GStreamer plugin

To use GStreamer plugin from source tree, set the following environment so that GStreamer can find it.

export GST_PLUGIN_PATH=$(pwd)/build/src/gstreamer

The debugging tool gst-launch-1.0 can be used to construct and pipeline and test it. The following pipeline will stream from the camera named “Camera 1” onto the default video display element on your system.

gst-launch-1.0 libcamerasrc camera-name="Camera 1" ! videoconvert ! autovideosink
