Trying to compile Kooha screen recorder, gstreamer not found

You can use SimpleScreenRecorder on the VF2 (low frame rate recommended), but that doesn’t work with Wayland.
I tried to compile Kooha, but it can’t find gstreamer.

I tried to compile with meson, but the file references gstreamer packages that can’t be found.

dependency(‘gstreamer-1.0’, version: ‘>= 1.20’)
dependency(‘gstreamer-pbutils-1.0’, version: ‘>= 1.20’)
dependency(‘gstreamer-plugins-base-1.0’, version: ‘>= 1.20’)

dpkg -l shows me a package gstreamer1.0-x, but I have no clue if that is to supposed to be the same, or if it is really something different.
And will the missing package gstreamer-pbutils-1.0 block it anyway?

I also went back to an older version of Kooha, so we have the correct version for gtk4.

git rev-list -n 1 --before=“2023-03-01 00:00” main
git checkout e25f7ed95d10ec9e5198dae6dc795a943f2845d2

Anyone able to tell me if there is still a way to compile Kooha?
