New Post: tracking stream duration

Hello.

I am working on a streaming app and I want to track the duration (in seconds) of the amount of the stream that has been played. My streaming source provides the duration (in seconds) at the beginning of the stream and I would like to display a progressbar, but I need a way of tracking how much of the stream has been played. This is an MP3 stream and thus I am following the 'Streaming MP3 example', but I am at a loss on how to track the amount of played stream.

Any help would be greatly appreciated.

Thanks.
