Dependencies

The image stitching library has the following dependencies:

Meson

The library makes use of the Meson build system. To correctly build this library you need to use the latest version of Meson:

First, make sure cmake, python dependencies, and ninja are installed

sudo apt-get install python3 python3-pip python3-setuptools \
                       python3-wheel ninja-build

Then use pip3 install Meson directly from its repository.

sudo -H pip3 install git+https://github.com/mesonbuild/meson.git

GStreamer

If using only the library, the required packages are:

sudo apt install libgstreamer-plugins-bad1.0-dev gstreamer1.0-plugins-bad

However, to also build the example please install:

sudo apt install libgstreamer1.0-dev libgstreamer-plugins-base1.0-dev gstreamer1.0-plugins-base libgstreamer-plugins-bad1.0-dev gstreamer1.0-plugins-bad

CppUTest

The following test library will allow you to run the unit tests of the project

sudo apt install libcpputest-dev

Building the project

To build the H.264 Motion Vector Extractor library natively run:

meson build --prefix /usr/
ninja -C build
ninja -C build test
sudo ninja -C build install

For additional customization, you may refer to the following options table:

`

-Denable-eval=enabled	Compile the evaluation version. Includes examples unless explicitly disabled.
-Dtests=disabled	Disable compilation of tests.
-Dexamples=enabled/disabled	If enabled, build and install the examples. Disabling it will not build them. The default action is building the examples but not installing them.
-Ddeveloper-mode=enabled	Install pre-commit hooks.
--prefix /usr	Set the installation path of the library
