So I ran into an issue 3 years ago where the 32-bit GStreamer plugins are unusable on Fedora and openSUSE despite these distributions shipping the needed 32-bit packages.
So did anyone manage to get winegstreamer.dll to work for 32-bit Windows applications on Fedora and openSUSE or is it widely known that one should avoid them when using Wine?
Note that of course I reported this issue to the distributions and this is where you'll find more details about this issue:
* Fedora https://bugzilla.redhat.com/show_bug.cgi?id=1472160 -> Reported against Fedora 26, then 28, still present in Fedora 32 but fixing this bug seems to have been postponed indefinitely.
* openSUSE https://bugzilla.opensuse.org/show_bug.cgi?id=1049452 -> Supposedly fixed on Tumbleweed 2 years ago but still present on openSUSE Leap 15.1
https://bugzilla.opensuse.org/show_bug.cgi?id=1172018 -> New bug for openSUSE Leap 15.1.
