Control VLC via DBUS

Start vlc with --control dbus:  
vlc --control dbus

Toggle play/pause on VLC:
qdbus org.mpris.MediaPlayer2.vlc /org/mpris/MediaPlayer2  org.mpris.MediaPlayer2.Player.PlayPause

Remove last track from playlist (requires previous alias):
alias rmvlc='qdbus org.mpris.MediaPlayer2.vlc /org/mpris/MediaPlayer2 org.mpris.MediaPlayer2.TrackList.RemoveTrack $(qdbus --literal org.mpris.MediaPlayer2.vlc /org/mpris/MediaPlayer2 org.mpris.MediaPlayer2.TrackList.Tracks | sed "s/\(.*{.*: \)\(.*\)\(]}]*\)/\2/")'

Clear entire track list:
alias clvlc='for a in {1..50}; do rmvlc; done 2>/dev/null' 

Instead of PlayPause you can call any of the MediaPlayer2 methods:
$> qdbus org.mpris.MediaPlayer2.vlc /org/mpris/MediaPlayer2
