This is preferable because it prevents things like disk corruption (requiring the user to delete the disk image when starting up) that I consistently ran into.
Without this change it segfaults when trying to play any media:
$ jellyfinmediaplayer
Warning: Ignoring XDG_SESSION_TYPE=wayland on Gnome. Use QT_QPA_PLATFORM=wayland to run on Wayland anyway.
libpng warning: iCCP: known incorrect sRGB profile

Segmentation fault (core dumped)
The backtrace shows pipewire being at fault:

Standalone mpv doesn't segfault (when directly playing the underlying
media files). I don't know why.
