Need help on how to use Pymedia!

[CptPicard]

Hi,
I am currently trying to use pymedia so to get the following informations
(author, song title, ...) from a mp3 file.
The documentation I downloaded is quite limited : It gives some clues on how
to get that information (method getInfo() from pymedia.audio.acodec).
However, it does not explain what has to be done prior to that call.
I downloaded pycar but it did not help me.

Could someone give me a more detailed documentation on pymedia or some clues
on how to get the information I need ?

Thanks for your help
