Malphas,
Like BSPeter said : all the info is in the SDK directory.
All you have to do is send a message to BSplayer and it will return the information.
Maybe you find some useful information in this topic :

I know it's C++ related, but you just need to find out how to get the handle to the BSPlayer window and how to send messages in your programming language.
