The following is a usage example of how to control VLC though DBUS, by simple using dbus-send. This bash script toggles between Play/Pause:
Stopped -> Play
Playing -> Pause
Pause -> Play
#!/bin/bash
if dbus-send --print-reply --session --dest=org.mpris.vlc /Player org.freedesktop.MediaPlayer.GetStatus | grep -Fq "int32 2"; then
# Match found
dbus-send --print-reply --session --dest=org.mpris.vlc /Player org.freedesktop.MediaPlayer.Play
else
# Match not found
dbus-send --print-reply --session --dest=org.mpris.vlc /Player org.freedesktop.MediaPlayer.Pause
fiIf you have qt-dbus (or libqt4-dev) installed, you can also use qdbus to toggle between Play/Pause
#!/bin/bash
qdbus org.mpris.MediaPlayer2.vlc /org/mpris/MediaPlayer2 org.mpris.MediaPlayer2.Player.PlayPause
