Live streaming with play back back functionality
<p>I need to develop live DVR with play back functionality with live streaming of radio. 
Like already some application doing:<a href="https://play.google.com/store/apps/details?id=audis.mobile.VRadioRecorderLite.views" rel="nofollow">V Radio Recorder</a>.
The main thing i need the play back functionality and live streaming. 
Like if User listened 20sec of radio then he can rewind to the 10sec.  </p>
