| − | === 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 and then exit
| |
| − | | |
| − | | |
| − | When D-Bus control interface starts, it does:
| |
| − | # unregister '/'
| |
| − | # register '/org/videolan/vlc'
| |
| − | | |
| − | | |
| − | | |
| − | The problem is that it does require dbus control to be loaded.
| |
| − | | |
| − | Possible ways to do that:
| |
| − | * check if /org/videolan/vlc is present before exit, and then ignore one-instance setting if dbus control isn't activated
| |
| − | * use service activation, but that mean we would have 1 GUI without dbus control, and 1 with dbus control
