Okay, so I've answered some of these for myself, thanks to the
excellent C API documentation, but I'm still having trouble on a
couple counts:

Still haven't figured this one out :-(  What's the most appropriate
way to identify an incoming stream as MP3 or Ogg Vorbis or whatever?

So, now I've figured out how to use pipeline.query_position().  Handy!
 However, I'd like to know if there is a way to install a callback
that will get called when the stream reaches a specific position... so
that I can avoid repeatedly polling.

Thanks for any advice!
