TODO for DBus integration
List all signals, methods with their arguments and return value
Decide what to do when org.videolan service is already registered by another instance of vlc: let the first instance do all the work ? replace it ? place vlc on the queue ?
Now if vlc is built with D-Bus >= 1.0.0 it will automatically register org.videolan.vlc, and no other instances of vlc will be allowed to replace it
Decide service bahaviour
Could vlc be a on-demand startable service, would it be useful ?
We just have to create a /usr/share/dbus-1/org.videolan.vlc.service:
Exec=/usr/bin/vlc -I dummy --control dbus
volume control => VolumeGet and VolumeSet
playlist => hard.... could we use xspf ?
timing of the input element (position, jump)
