This is needed to use option type 'feature'. This is a tri-state (auto/enabled/disabled) which comes with utility to enable them all, or disabled them all to avoid any dynamic selection happening. It can also be used as value to any "required" field. This will be used in GStreamer support. If you don't have a recent enough meson in your distribution, you can always install or upgrade your version using pip3. pip3 install --user meson pip3 install --user --upgrade meson Signed-off-by: Nicolas Dufresne <nicolas.dufresne@collabora.com> Reviewed: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>

**A complex camera support library for Linux, Android, and ChromeOS**
|
|
|
|
Cameras are complex devices that need heavy hardware image processing
|
|
operations. Control of the processing is based on advanced algorithms that must
|
|
run on a programmable processor. This has traditionally been implemented in a
|
|
dedicated MCU in the camera, but in embedded devices algorithms have been moved
|
|
to the main CPU to save cost. Blurring the boundary between camera devices and
|
|
Linux often left the user with no other option than a vendor-specific
|
|
closed-source solution.
|
|
|
|
To address this problem the Linux media community has very recently started
|
|
collaboration with the industry to develop a camera stack that will be
|
|
open-source-friendly while still protecting vendor core IP. libcamera was born
|
|
out of that collaboration and will offer modern camera support to Linux-based
|
|
systems, including traditional Linux distributions, ChromeOS and Android.

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}
|
|
|
|
for libcamera: [required]
|
|
meson ninja-build python3-yaml
|
|
meson (>= 0.47) ninja-build python3-yaml
|
|
|
|
If your distribution doesn't provide a recent enough version of meson,
|
|
you can install or upgrade it using pip3.
|
|
|
|
.. code::
|
|
|
|
pip3 install --user meson
|
|
pip3 install --user --upgrade meson
|
|
|
|
for device hotplug enumeration: [optional]
|
|
pkg-config libudev-dev
|
|
|
|
for qcam: [optional]
|
|
qtbase5-dev libqt5core5a libqt5gui5 libqt5widgets5
|
|
|
|
for documentation: [optional]
