Additional context

I started the system with the environment variable BOTTLES_USE_SYSTEM_GSTREAMER=1, but it doesn't seem to affect it at all. It doesn't matter whether I define it at the bottle level or at the global level. I have also verified that inside the bottle there is the directory /usr/lib/x86_64-linux-gnu/gstreamer-1.0 containing all the .so files.

The plugins are correctly installed on my system:

With the ge-proton10-15 executor, the videos work correctly (which is what I use as a workaround), but I'm really interested in getting them to work with soda as well.
