iPhone:How do i stream LIVE audio/video programatically from my iPhone application?

Question

Hello,

I am going to develop an iPhone application, which should stream audio and video LIVE streaming programatically from some web page. I want to know the answer for following questions?

1. How to programmatically stream(buffer by buffer?) LIVE audio/video in iPhone development? Does MoviePlayerViewController class playMovie does that for live video streaming?

2. Is it possible to do real time streaming (uses rtsp://) programmatically?

3. If i want to test some LIVE audio/video streaming through some test environment, what should i do for that? I need to setup any server locally etc.?

4. What types of streaming is available and iPhone supports on 2.x to 3.2?

Appreciate your helps in advance.

Thank you.
