If we don't specify a path for loading, the runtime linker will search for the library instead, which will use the usual mechanisms: RPATHs, LD_LIBRARY_PATH, PATH (on Windows), etc. Also try harder to load a non-devel libpython using INSTSONAME, if available.

gst-python
gst-python is an extension of the regular GStreamer Python bindings based on gobject-introspection information and PyGObject.
It provides two things:
-
"syntactic sugar" in form of overrides for various GStreamer APIs that makes them easier to use in Python and more pythonic; and
-
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.IntRangeetc.
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.
