Flash / ActionScript 3: Load .FLV file into a MovieClip and start playing that FLV file

actionscript-3, flash

Solution

Not explicitly answering your question, but there are a number of open source FLV players in the wild. I'd approach the problem by grabbing one of those and seeing how they handle playing video.

FPlayer would be an excellent starting point. Here is the class that is doing the work. It is fairly straight forward, but using a project like this would probably save you some time.

This snippet should do the trick in an extremely bare bones fashion:

var vid:Video = new Video(320, 240);
addChild(vid);

var nc:NetConnection = new NetConnection();
nc.connect(null);

var ns:NetStream = new NetStream(nc);
vid.attachNetStream(ns);

var listener:Object = new Object();
listener.onMetaData = function(evt:Object):void {};
ns.client = listener;

ns.play("externalVideo.flv");

from here
