you should select the VLC driver with the [driver vlc( message, then use
the message [device $1( to open something (a file, a stream...)
but note 1 : $1 in device message should be a full path like the one you
enter in VLC (ex : file://home/me/mavideo.avi or udp://@
2 : vlc driver didn't know the resolution of the video, you should set it
yourself with the [dimen width height( message

see attachment

I note that the vlc-videoplugin.pd is empty, this could be filed with some
informations like above.



do it yourself
