Here is the one-stop manual. For more details (or latest information), please check https://code.videolan.org/videolan/dav1d.
dav1d relies on meson build system (and ninja), so meson installation is required. It might be best to see https://mesonbuild.com/ to know how to do it, but here are the steps:
$ sudo apt-get install python3 python3-pip python3-setuptools python3-wheel ninja-build$ pip3 install meson (as root)
