== TODO for DBus integration ==

=== List all signals, methods with their arguments and return value ===

=== 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:
----
[D-BUS Service]

Name=org.videolan.vlc

Exec=/usr/bin/vlc -I dummy --control dbus
----


=== Clarify one instance mode ===

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 the service.

When vlc starts it registers the org.videolan.vlc service on the session bus
* if it succeeds, it register '/' object on it
* if it fails:
** if "one-instance" is false, just warn that it didn't register the service
** if "one-instance" is true, the mrls given on the command line are passed to the owner of org.videolan.vlc through D-Bus interface


When D-Bus control interface starts, it does:
# unregister '/'
# register '/org/videolan/vlc'

=== Missing features ===

volume control => VolumeGet and VolumeSet

playlist => hard.... could we use xspf ?

timing of the input element (position, jump)

preferences ?


== List of signals and methods ==



=== Signals ===

'ItemChange' 's' : Emitted when a new input element is played, the string contains the filename, or the input name if it has some metadata.

'NewInstance' 'i' : Emitted when vlc control interface is started, with vlc pid

=== Methods ===

''''Method' (input signature) = (output signature) : description'''

'GetPlayStatus' () = (s) : return "play" "pause" "stopped" or "unknown"

'GetPlayingItem' () = (s) : return the filename of the current item being played, or it's name if it has some metadata. Same data provided by "ItemChange"

'ToglePause' () = (b) : toggle the play/pause status, and start playing if it was stopped, return true if playing, false if paused

'AddMRL' (sb) = () : add string to the playlist, and play it if bool is true

'Nothing' () = () : do nothing, just here for tests, and code example

'Quit' () = () : exits vlc

'Stop' () = () : stop playlist

'Prev' () = () : plays previous playlist item

'Next' () = () : plays next playlist item
