Show on title main form VLC current time positon, length track, pause or playing file

[korp2]

Show on the title main form VLC current time positon, length track, pause or playing file.

I don't find it in menu Preference VLC.

I assume some way's to solve the task:
Write a script in lua. I find how get time
vlc.var.get(input,"time")
and status
vlc.playlist.status()

How i can send it to title main form VLC? If it's impossible, then to my created form with function Create_dialog()
And how a script always autorun?
Is necessary create thread or use "repeat" with "wait"?

What algorithm better to do this task?

P.S. Sorry, for my bad English

You can set meta title for current media:

input.item(): Get the current input item. Input item methods are:
:set_meta(key, value): Set meta data.

You need to write an Interface script as it allows a periodic activity to update the running time and it supports autorun in VLC preferences.
