Loading video files

Flash Player 9 and later, Adobe AIR 1.0 and later

Loading videos using the NetStream and NetConnection classes is a multistep process. As a best practice, the steps of adding the Video object to the display list, attaching the NetStream object to the Video instance, and calling the NetStream object’s play() method should be performed in the specified order:

  1. Create a NetConnection object. If you are connecting to a local video file or one that is not using a server such as Adobe's Flash Media Server 2, pass null to the connect() method to play the video files from either an HTTP address or a local drive. If you are connecting to a server, set the parameter to the URI of the application that contains the video file on the server.

    var nc:NetConnection = new NetConnection(); 
  2. Create a new Video object that display the video and add it to the stage display list, as shown in the following snippet:

    var vid:Video = new Video(); 
  3. Create a NetStream object, passing the NetConnection object as an argument to the constructor. The following snippet connects a NetStream object to the NetConnection instance and sets up the event handlers for the stream:

    var ns:NetStream = new NetStream(nc); 
    ns.addEventListener(AsyncErrorEvent.ASYNC_ERROR, asyncErrorHandler); 
    function netStatusHandler(event:NetStatusEvent):void 
        // handle netStatus events, described later 
    function asyncErrorHandler(event:AsyncErrorEvent):void 
        // ignore error 
  4. Attach the NetStream object to the Video object using the Video object’s attachNetStream() method, as seen in the following snippet:

  5. Call the NetStream object’s play() method with the video file url as an argument to start the video playing. The following snippet loads and plays a video file named “video.mp4” in the same directory as the SWF file:
