python3-gst
This module contains a wrapper that allows GStreamer applications to be
written in Python.
If you want to use multimedia in your python app on a Sailfish device, you'll need this module.
And if you want to use qml in a noarch app and miss some gstreamer options in Qt Multimedia, you'll need this module too (e.g. Equalizer or Set speed/pitch on audio/raw streams).
