Meson

The image projector makes use of the Meson build system. To correctly build this library you need to use version 0.60 of Meson:

First, make sure Python dependencies and Ninja are installed.

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

Then use pip3 to install Meson.

sudo -H pip3 install meson==0.60

Hotdoc

sudo -H pip3 install hotdoc

Building the project

Once you have met the requirements, execute the following commands:

cd gst-rr-projector
meson setup --prefix=/usr build
ninja -C build
sudo ninja -C build install

To verify that the plug-in was correctly installed, you should run:

gst-inspect-1.0 rrfisheyetoeqr

with expected output
