# 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
```python
import gi
gi.require_version('Gst', '1.0')
from 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`.
