Switching from xaudio

Hi,

My homebuilt car mp3 player has started acting up on certain mp3's (xaudio
simply crashes with signal 32) so I would like to start using libmad.
However with the lack of documentation this seems to be a little daunting!
I will be using it in an asynchronous setting with a thread to handle the
call backs (it will also set up the mmap() for the input and handle
writing the output into the appropriate device), this much I have
acertained as being possible from minimad. The only thing I think I am
going to have problems with is that the decoder doesn't report any status
as far as track time and elapsed time which are essential to this project.
Am I missing something simple or is this an issue (if it is, how should I
work around it?)
Thanks

Anthony
