You get state change messages on the pipeline's bus (make sure to also
check for message->src == pipeline), only when you set the pipeline to
NULL state you won't get any messages for that.

You will also get an ASYNC_DONE message to signal that the pipeline has
prerolled, at which point you can usually query duration and do seeks
and things like that.
