I used to have my media keys bound to prev/next/pause with i3 like so
bindsym XF86AudioPrev exec --no-startup-id mpc prev
But I wanted to also use other players so I set it to
bindsym XF86AudioPlay exec --no-startup-id playerctl play-pause
which runs via the D-Bus and controls all media players that follow the MPRIS Spec readme
So is there a MPRIS module for mpd or an adapter that runs as a service and translates the mpris signals for the mpd? I couldn't find any, but it would be nice to use the media keys for both, not just for one XOR the other.
