Well, I tried to write something, it works for me at least but partially, I will apriciete if someone look at the code and tell me whats wrong and what could be better. I tried first with mplayer -slave -idle -quit and than sending signals to stdin but I find this very slow, progress bar was not smooth because I have to use atleast time.sleep(0.05) to wait for mplayer, then I removed the -quit and tried to parse mplayers output but then, I dont know how to watch for eof so I can not requestnextsong... How do I do that? Thx

mplayer.py
