how can i get a shoucast stream to start playing almost instantly

Question

I am still fixing my radio app and it is going well and you guys have been great at helping as a resource!!

One thing that I (and my end client) have been worried about is that the stream takes 30 seconds to 45 seconds (wifi vs cell networks vs location mobile user is at) for the stream to start playing.

They are using shoutcast as a services and I pull the streams from their shoutcast account. The streams are MP3s.

Is there a way to make it so that a few seconds after play button is pressed, the stream starts playing???

Here is my code:

Answer 1

Outcast is not great at streaming; however making a buffer class and then controlling the player start part as a percentage of buffering sort of worked.
