Andoni Morales Alastruey 3683cd9052 gst-python: fix build and usage in Windows 
Windows require the python module to be linked to GStreamer.
With msvc and /FORCE:UNUSED, links succeeds but it failes to
load the library at runtime.

gst-python

gst-python is an extension of the regular GStreamer Python bindings based on gobject-introspection information and PyGObject.

It provides two things:

  1. "syntactic sugar" in form of overrides for various GStreamer APIs that makes them easier to use in Python and more pythonic; and

  2. support for APIs that aren't available through the regular gobject-introspection based bindings, such as e.g. GStreamer's fundamental GLib types such as Gst.Fraction, Gst.IntRange etc.

Prerequisites

These libraries are needed to build gst-python:

  • gstreamer core
  • gst-plugins-base
  • pygobject

You will also need pygobject and glib installed. On debian-based distros you can install these with:

sudo apt build-dep python3-gst-1.0

Only Python 3 is supported.

Building

meson setup builddir && ninja -C builddir
meson install -C builddir

Using

Once installed in the right place, you don't need to do anything in order to use the overrides. They will be loaded automatically on

import gi
gi.require_version('Gst', '1.0')
gi.repository import GObject, Gst

Note that additional imports will be required for other GStreamer libraries to make use of their respective APIs, e.g. GstApp or GstVideo.
