Publish gst-python on PyPI

The common way to pull in dependencies for a Python project is to install them via pip: either directly, or via an install_requires stanza in setup.py. This requires the dependency to be available on PyPI. As gst-python is not available on PyPI, it can't be pulled in in the normal way.

I realise that the package is somewhat special, requiring various GStreamer headers and introspection data be installed. But if PyGObject can do it, presumably gst-python can too.

My goal is to use mesonpep517 to publish gst-python, it should be quite straight forward but I haven't looked into it yet. I already proposed to move PyGObject to using it instead of having a setup.py.

I was wondering if there was any progress made on this matter. What is the proper way to install the gst-python package? Can someone refer me to some basic tutorial on how to install this package and get some basic example up and running?

I'd also like to know how to do this. I'm trying to build gstreamer on Windows using meson. A lot of it builds, but gst-python and pygobject are not built. From the meson-log.txt file:

added Bindings Python labels

This seems to still be valid, I guess one the mesonpep517 is no longer the best way to do it, https://github.com/mesonbuild/meson-python/ seems to be the newest thing in meson pythoness ?
