Commit 08e5a1f7 authored by Gildas Bazin's avatar Gildas Bazin

* include/os_specific.h, src/libvlc.[c,h], src/misc/win32_specific.c: new win32 specific option (--one-instance) to have only one instance of vlc running at once.
 Running another vlc (with --one-instance as well) will only transfer the requested playlist items to the first instance.
