Additional information

Seems that there are some missing components needed for this integration missing from Core, which prevents the integration from working out of the box.

I got it working by executing the following commands:

apk add gstreamer gstreamer-dev gstreamer-tools pkg-config build-base cairo-dev cairo cairo-tools gobject-introspection-dev gst-plugins-good gst-plugins-bad gst-plugins-ugly  

pip install PyGObject
pip install pgi

After executing those commands in the HA container i was able to use the Gstreamer integration without any errors. I would really appreciate if any dev would implement those dependencies into the project.
