Passing parameters to Red5 application with OSMF
Recently working on a Flex project i had the need to implement a video player in my Flex application. Although my needs did not involve media streaming, rather only playing live streams, i still needed a  industry standard code to my solution. Thats where OSMF (Strobe)  came handy. Tracking OSMF for a few months, seems like we finally have a usable version – OSMF 1.0  (0.93).
The second hurdle was passing parameters to RTMP application. As the traditional Netconnection class allows connection params in the constructor, i was unable  to find a example on the web involving OSMF and passing parameters to RTMP applications. Finally after some struggle , god’s grace 
i think i nailed it. Here is the code snippet showing you how to connect to a RTMP application and passing parameters when connecting.
Note: Make sure you have latest OSMF revision from trunk added to your project classpath.

mediaElement = new VideoElement(new StreamingURLResource(REMOTE_STREAMING,StreamType.RECORDED,NaN,NaN,vector),new NetLoader);
container = new MediaContainer();
container.addMediaElement( mediaElement );
// Flex requires a DisplayObject to be wrapped in Flex Framework UI Abstraction
videoParent.addChild( container );
// MediaPlayer is a virtual controller. Assign it a media element and it will autoplay the media by default.
mediaPlayer = new MediaPlayer(mediaElement);
mediaPlayer.addEventListener(MediaPlayerStateChangeEvent.
