Assuming you use spider, you have the following pipeline (in gst-launch
syntax, you'll get the idea):

filesrc location=file ! spider ! osssink

The listener can simply be added to the pipeline like this:

filesrc location=file ! spider ! identity ! osssink

Then attach your signal callback to the identity object after reating
it, and you're done.
