Using PyGObject to control gstreamer under MSYS2 from windows

[Peter]

Hello,

I wanted to provide an update as I've managed to figure out a solution to
the immediate part of issue 1) the solution is discussed on this page.
https://stackoverflow.com/questions/76458520/create-an-executable-from-a-python-and-pygtk-script-under-windows
"chcp.com 65001"
I am able to play a video using the example
https://gstreamer.freedesktop.org/documentation/tutorials/basic/hello-world.html?gi-language=python
while under a msys2 shell now.

I am still stuck with the second question regarding what package is
equivalent to gstreamer1.0-python3-plugin-loader on pacman for msys2.
