This repository can use a modified v4l-utils tree as a git submodule. The following example shows how to build using that submodule on a development PC.

  1. Add and initialize the submodules
git submodule add -b scarthgap/v4l-utils-1.26.1 \
  https://github.com/clear-code/v4l-utils v4l-utils
git submodule add https://github.com/clear-code/cutter.git cutter
git submodule update --init --recursive
  1. Build the project with Meson
./scripts/build.sh

The script builds v4l-utils with Meson and installs it locally under v4l-utils/_install_root, builds the cutter submodule under _local when Cutter is not available on the system, and then configures and builds this project with Meson, passing -Dlibv4l-dir that points to the local v4l-utils install.

Note: You will usually need meson, ninja, and development packages for dependencies. On Debian/Ubuntu, for example, install something like:

sudo apt install meson ninja-build pkg-config libglib2.0-dev

Notes:

  • If you omit -Dlibv4l-dir, Meson auto-detects a v4l-utils directory (the _install_root/usr install tree if present). If no local tree is found, the system v4l-utils is used, which is what Yocto builds rely on.
  • Integrating this into Yocto requires adapting your existing recipes and is outside the scope of this document.
