I do get dbus name registration very well. However, the libvlc
initialization sequence and the dbus control module do not share the
same connection, because they are running on different threads while
connection handling in dbus is not thread safe.
They are then to be considered as two separate entities on the bus
because a name is owned with the scope of a dbus connection. It is not
The role of the connection used in src/libvlc.c is only to make an mpris
client call, it can not make any use of the well-known name, given that
only the dbus control module can answer calls for which the well-known
name is set as a destination

It will have to be registered indeed, but over a different, private
connection unless there is a way to reuse the same connection in the
dbus control interface.
This is probably where lies our misunderstanding, do you know how I can
use the same connection for the single instance mode and the dbus
control module ?
