iPad + RTSP IP Camera

I have set my wowza server with the tutorial for live rtsp video streaming for the all players and i`m trying to get it working on my ipad but when i accesss the url it says that it is playing but the screen is black. When i try it in LiveVideoStreaming example it works perfectly. Have any ideas, are there any aditional settings to be made?

Here is my log.

Use Cupertino streaming for IPad. Use HTML5 video tag and m3u8 url:

<html>
<head> 
  <title>Cupertino Streaming</title>
</head>
<body>
<video controls src="http://[wowza-address]:1935/[app-name]/[stream-name]/playlist.m3u8">
</video>
</body>
</html>

What is the encoder or video source? Which tutorial are you following?
