gstreamer is unusable for Wine due to it relying on glib and that is broken since glib-2.32.0: https://bugs.winehq.org/show_bug.cgi?id=30557
The way forward is to replace winegstreamer too.
I think a better way forward would be to fix the issue with GLib (either from the GLib side or the Wine one) and to upgrade winegstreamer to a non-obsolete version of GStreamer.
