[MPlayer-users] About some API

[Alan]

So... I know that mplayer does not a library, so word API here not 
valid, but I can't called my question other than that :) just sorry :)

so. I want to write a Perl script (plugin) for my X-Chat, so. I want to 
post via IRC information about what audio|video track is currently 
playing. I mean - I start mplayer and xchat plugin send into irc channel 
info about what file I opened, bitrate, length, file size and other 
useful information. So I need, that mplayer store this information 
somewhere (maybe ~/.mplayer/nowplaying or other way).

I have some question about: is there a feature with which I can create 
such script? Or may be you (developers) can create that feature? Just 
need to store information in text file somewhere, and it needs to be a 
X-platform way.

Or maybe I'm lame and it can create more quickly and easily?
