I'm writing a plugin which should take an mp3 file from a network source (like a web server) and then just stream it (much likesoundcloud etc.). The problem is that i can't use the WebStream class since I need to do a post to the url in order to trigger the download. I created a class which can download the mp3 file. If I save it as a file and then replay it everything is fine. If i try to stream it nothing works. What should i return in the getInput stream? I've tried all sorts of various Stream classes but everything ends up with the render just saying playback not possible (rather quick).
