Adobe Air video player blank video on iPad

问题

Any idea why this simple piece of code wont work on iPad mobile? This works great on Android tablets, the desktop version, web version, etc. On iPad, the video is blank

<?xml version="1.0" encoding="utf-8"?>
<!-- controls\videoplayer\VideoPlayerEvent.mxml-->
<s:Application xmlns:fx="http://ns.adobe.com/mxml/2009" 
               xmlns:s="library://ns.adobe.com/flex/spark" 
               xmlns:mx="library://ns.adobe.com/flex/mx">


    <s:VideoPlayer 
        source="rtmp://fmsexamples.adobe.com/vod/mp4:_cs4promo_1000.f4v"
        width="500" height="500" x="500" y="500"
        loop="true" />
 </s:Application>

Taken from my comment:

iOS doesn't playback of h.264 encoded mp4s or f4vs through the standard Flex VideoPlayer. Only ways you can play those back are through StageWebView and StageVideo
