[vlc] Reading stream position with separate program

[Andrew Cunningham]

Hi all,

I have a HTPC which has a 2 line VFD, in the style of standalone 
DVD-players, on the front. This displays current position / file length when 
videos are playing and supports a lot of media players but unfortunately not 
VLC. It is a Soundgraph iMon VFD unit, and thankfully it comes with a plugin 
mode where I can just write a program that calls a SetText routine from a 
downloadable API to display whatever I want on the VFD.

I have written a test plugin that just prints current date and time to the 
display. What I need now is to query a running VLC instance for the current 
position and total file length so that I can show that.
