Flash 使用NetConnection类

我正在尝试使用NetConnection类连接到外部服务器上的实时视频源。我已将其设置为在用户单击播放按钮时开始播放我的视频，但是，每次单击播放按钮时，我的输出中都会显示：

ArgumentError:错误#2126:必须连接NetConnection对象。 在flash.net:：NetStream/ctor（）上 在flash.net:：NetStream（）上 在Over/connectLiveStream（）上[Over:：frame2:31]

你知道为什么这不起作用吗？以下是（我认为相关的）代码：

提前感谢。

我正在从adobe文档网站复制以下内容：

package {
import flash.display.Sprite;
import flash.events.*;
import flash.media.Video;
import flash.net.NetConnection;
import flash.net.NetStream;

public class NetStatusEventExample extends Sprite {
    private var videoURL:String = "Video.flv";
    private var connection:NetConnection;
    private var stream:NetStream;

    public function NetStatusEventExample() {
        connection = new NetConnection();
        connection.addEventListener(NetStatusEvent.NET_STATUS, netStatusHandler);
        connection.addEventListener(SecurityErrorEvent.SECURITY_ERROR, securityErrorHandler);
        connection.connect(null);
    }

    private function netStatusHandler(event:NetStatusEvent):void {
        switch (event.info.code) {
            case "NetConnection.Connect.Success":
                connectStream();
                break;
            case "NetStream.Play.StreamNotFound":
                trace("Unable to locate video: " + videoURL);
                break;
        }
    }

    private function connectStream():void {
        var stream:NetStream = new NetStream(connection);
        stream.addEventListener(NetStatusEvent.NET_STATUS, netStatusHandler);
        stream.addEventListener(AsyncErrorEvent.ASYNC_ERROR, asyncErrorHandler);
        var video:Video = new Video();
        video.attachNetStream(stream);
        stream.play(videoURL);
        addChild(video);
    }

    private function securityErrorHandler(event:SecurityErrorEvent):void {
        trace("securityErrorHandler: " + event);
    }

    private function asyncErrorHandler(event:AsyncErrorEvent):void {
        // ignore AsyncErrorEvent events.
    }

}
}

class CustomClient {
public function onMetaData(info:Object):void {
    trace("metadata: duration=" + info.duration + " width=" + info.width + " height=" + info.height + " framerate=" + info.framerate);
}
public function onCuePoint(info:Object):void {
    trace("cuepoint: time=" + info.time + " name=" + info.name + " type=" + info.type);
}
}

希望这能有所帮助，如果出现安全错误，您也需要在连接的流媒体服务器上设置跨域策略文件

您应该向

nc

对象添加一些事件处理程序，以查看

NetStatusEvent

的运行情况。您可以在此处给出connection.connect（）参数的示例吗？在您的代码中，您正在传递null。我想知道是否唯一允许的协议是rtmp协议？我希望不是因为我希望服务器是GlassFish（java）服务器。。。
