HTTP live streaming with ios

My app is rejected by apple and they give a reason

We found that your app does not use the HTTP Live Streaming protocol, with a baseline stream of 64 kbps, to broadcast streaming video

Then I search for a solutions and over internet all the solutions suggest that I have to use .U8F8 and .ts extension for live streaming but my app has mp4 format. I already used MPMoviePlayerController for streaming.

So my question is:

1. Do I have to convert mp4 video to M8U8?
2. Do I have to use MPMoviePlayer?
3. Can I convert mp4 video to M8U8 format during run-time and how to implement live streaming
4. Is there any example code available for HTTP live streaming?

Thanks in advance.
