How does the flash player play local mp4 file

Question

I want to play the local mp4 file in adobe flash player, the source code show following:

package
        {
           import flash.display.Sprite;
           import flash.net.NetConnection;
           import flash.net.NetStream;
           import flash.text.TextField;
           import flash.media.Video;

           public class Exploit extends Sprite
           {

              public function Exploit()
              {
                 greeting = new TextField();
                 super();
                 greeting.text = "Loading...";
                 greeting.x = 100;
                 greeting.y = 100;
                 addChild(greeting);
                 MyVideo = new Video();
                 addChild(MyVideo);
                 MyNC = new NetConnection();
                 MyNC.connect(null);
                 MyNS = new NetStream(MyNC);
                 MyVideo.attachNetStream(MyNS);
                 MyNS.play("http://techslides.com/demos/sample-videos/small.mp4");
              }

              public var MyNC:NetConnection;

              public var MyNS:NetStream;

              private var greeting:TextField;

              public var MyVideo:Video;
           }
        }

then I use mxmlc.exe to generate .swf file. Open the swf file, it works. But when I modify MyNS.play("http://techslides.com/demos/sample-videos/small.mp4") to MyNs.play("small.mp4"), and then use mxmlc.exe to generate .swf file. Open it, it cannot play the small.mp4 file.(Note: small.mp4 locates the same directory with swf file).

Anyone give me suggestion?

For anyone with same problem. Try setting your swf output options from "access network files only" to being "access local files only" then test again. — VC.One

I don't think flash supports MP4 natively. I would suggest looking at a codec

Here is the list of natively supported codecs by the Flash Player:

If you need to play something not natively supported, there are external API's that will allow you to do so, just chose a Flash Sound API:
