A lightweight camera application, designed to start quickly in a bare environment. It is named twincam as it is built with automotive in mind like a twin-cam engine, it is simply the name of the application.
On CentOS Stream 9:
sudo dnf install -y 'dnf-command(config-manager)'
sudo dnf config-manager --set-enabled crb
sudo dnf install -y epel-release
On Fedora and CentOS Stream 9 (steps should be similar on other platforms):
sudo dnf install -y git gcc g++ libevent libevent-devel openssl openssl-devel \
gnutls gnutls-devel meson boost boost-devel python3-pip libdrm libdrm-devel \
systemd-udev doxygen cmake graphviz libatomic texlive-latex cppcheck \
libyaml-devel clang zip valgrind libasan findutils libjpeg-turbo-devel \
systemd-devel mesa-dri-drivers SDL2-devel libglvnd-devel mesa-libgbm-devel
On Clear Linux:
sudo swupd bundle-add vim git dev-utils devpkg-gnutls devpkg-boost \
devpkg-libevent devpkg-libdrm ccache devpkg-SDL2
On Debian/Ubuntu:
sudo apt install -y clang gnutls-dev libboost-dev meson cmake pkg-config \
libevent-dev libdrm-dev gcc make autoconf automake cppcheck libsdl2-dev \
meson vim libgtest-dev libyaml-dev curl zip valgrind libasan5 git \
libjpeg-dev python3-pip
On Alpine (enable community repo in /etc/apk/repositories):
sudo apk add git vim gcc meson g++ pkgconf gnutls-dev cmake boost-dev py-pip \
ccache libevent-dev libdrm-dev
On all platforms:
sudo pip install jinja2 ply pyyaml
git clone https://git.libcamera.org/libcamera/libcamera.git
cd libcamera
meson build --prefix=/usr && ninja -v -C build && sudo ninja -v -C build install
cd -
git clone https://github.com/ericcurtin/twincam
cd twincam
meson build --prefix=/usr && ninja -v -C build && sudo ninja -v -C build install
Then switch to a tty without a Desktop Environment (Gnome, XFCE, etc.) running via Ctrl+Alt+F? (whichever tty does not have DE running F1, F2, F3, etc.) and run:
twincam
To install as a quick booting camera application, you can install via:
sudo ./install.sh
and reboot to test. There will be an rpm soon.
