Python Development Environment Setup for GStreamer

The default method for installing packages from distros is normally fine. venv is usually the way to go instead if you need to pip install the latest packages and want to avoid conflicts with system packages. .

Gst-Python Installation for System Python

Install GStreamer GObject Introspection overrides for Python 3 (python3-gst-1.0). Note that this package works for system-level of Python, see the next section for Python venv.

$ sudo apt install python3-gst-1.0
$ dpkg -L python3-gst-1.0

Gst-Python Installation for Venv

Download matched version:

Make sure you also have python-gi-dev installed on system.

$ sudo apt install python-gi-dev

Build The Shared Module

$ cd gst-python-1.24.9
$ meson setup builddir
$ meson compile -v -C builddir

I haven't figured out how to configure the installation path yet, so just copy files manually to the correct override location.

$ cp gi/overrides/Gst*.py <your-venv-root>/lib/python3.12/site-packages/gi/overrides/
$ cp builddir/gi/overrides/_gi_gst.cpython-312-x86_64-linux-gnu.so <your-venv-root>/lib/python3.10/site-packages/gi/overrides/
