Cannot Get mpv-mpris To Show Up In Playerctl

[ZachIndigo]

If I load mpv without mpris.so, the video plays as normal, and nothing shows up in playerctl -l. However, if I load mpv with --script=~/.config/mpv/scripts/mpris.so, and add the relevant dbus interfaces in /usr/lib/dbus-1/system.d/, nothing shows up in playerctl -l, and I get the following output: `An object is already exported for the interface org.mpris.MediaPlayer2 at /org/mpris/MediaPlayer2 (process:27778): GLib-GIO-CRITICAL **: 15:59:09.590: g_dbus_connection_register_object: assertion 'error == NULL || error == NULL' failed An object is already exported for the interface org.mpris.MediaPlayer2 at /org/mpris/MediaPlayer2 (+) Video --vid=1 () (h264 1280x720 30.000fps) (+) Audio --aid=1 (*) (aac 2ch 44100Hz) AO: [pulse] 44100Hz stereo 2ch float VO: [gpu] 1280x720 yuv420p AV: 00:00:04 / 00:04:53 (1%) A-V: 0.000

and add the relevant dbus interfaces in /usr/lib/dbus-1/system.d/

What do you mean by this?

It looks like you're loading the plugin multiple times. eg you're adding it to the command with --script and also have mpris.so installed in ~/.config/mpv/scripts/mpris.so and/or /etc/mpv/scripts.

The plugin doesn't currently protect against this and won't work correctly if loaded multiple times.

My dbus denies everything except what I allow in /usr/share/dbus-1/system.d/, I believe it has to do with how Arch Linux does pipewire.

So I tried running mpv without the command (using ~/.config/mpv/scripts/mpris.so), and moving mpris.so and loading it manually, and in both cases nothing pops up in dbus.

$ playerctl -l
mpd
mpd

$ dbus-send --session --dest=org.freedesktop.DBus --type=method_call --print-reply /org/freedesktop/DBus org.freedesktop.DBus.ListNames
method return time=1618424795.126584 sender=org.freedesktop.DBus -> destination=:1.282 serial=3 reply_serial=2
   array [
      string "org.freedesktop.DBus"
      string ":1.205"
      string "org.freedesktop.Notifications"
      string ":1.7"
      string "org.freedesktop.login1"
      string "org.freedesktop.ReserveDevice1.Audio0"
      string ":1.207"
      string ":1.72"
      string ":1.73"
      string ":1.40"
      string "org.freedesktop.DisplayManager"
      string ":1.41"
      string ":1.282"
      string ":1.75"
      string "org.freedesktop.PolicyKit1"
      string "org.bluez"
      string ":1.76"
      string ":1.10"
      string ":1.77"
      string ":1.33"
      string ":1.11"
      string "org.pulseaudio.Server"
      string ":1.14"
      string ":1.277"
      string ":1.38"
      string ":1.3"
      string ":1.39"
      string ":1.4"
      string "org.freedesktop.RealtimeKit1"
      string "org.mpris.MediaPlayer2.mpd"
   ]

And in both cases, mpv doesn't output any errors or messages except for what is playing
