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:
-
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();
nc.connect(null);
-
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();
addChild(vid);
-
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(NetStatusEvent.NET_STATUS,netStatusHandler);
ns.addEventListener(AsyncErrorEvent.ASYNC_ERROR, asyncErrorHandler);
function netStatusHandler(event:NetStatusEvent):void
{
// handle netStatus events, described later
}
function asyncErrorHandler(event:AsyncErrorEvent):void
{
// ignore error
}
-
Attach the NetStream object to the Video object using the
Video object’s
attachNetStream()
method, as seen
in the following snippet:
vid.attachNetStream(ns);
-
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:
ns.play("video.mp4");
