Fullscreen mode not available for libvlc1.1 (Win32)
For libvlc1.1 on Win32, fullscreen mode is not implemented. Actually, the libvlc api pertaining to fullscreen is just a no-op.
In modules/video_output/drawable.c (line 150), the vout window provider module that processes "drawable-hwnd" just ignores VOUT_WINDOW_SET_FULLSCREEN which falls back in default : "not implemented".
For developers that used libvlc1.0, this can be seen as a regression, and there is no means to even work around this issue.
