Switch to mpris-player-zbus
I am in the process of packaging podcats for debian. The only library missing is mpris-player. However, upstream is retired and it doesn't compile against the newer dbus and glib rust libs in debian. I tried patching mpris-player but it would essentially mean a complete rewrite of the crate. If you could consider switching to the mpris-player-zbis by the Pop!OS developers, I could finish the packaging and podcast s would land in the debain repos (soon™).
Cheers
