我遇到了闪存问题，我不太熟悉。我将这段代码基于视频聊天示例中 wowza 媒体服务器附带的代码，但与该示例不同，flash 不会提示我是否允许使用摄像机。

以下是我的动作脚本：

import flash.events.MouseEvent;
import flash.events.NetStatusEvent;
import flash.media.Camera;
import flash.media.Microphone;
import flash.media.Video;
import flash.net.NetConnection;
import flash.net.NetStream;
import flash.system.Security;
import flash.system.SecurityPanel;
import flash.display.Sprite;
import flash.text.TextField;
import flash.events.StatusEvent;

public class QandA extends Sprite {
    Security.LOCAL_TRUSTED;

    private var nc:NetConnection = null;
    private var camera:Camera;
    private var microphone:Microphone;
    private var nsPublish:NetStream = null;                      
    private var nsPlay:NetStream = null;
    private var videoCamera:Video;
    public var prompt:TextField;

    public function QandA():void {
        stage.align = "TL";
        stage.scaleMode = "noScale";
        videoCamera = new Video(160,120);
        addChild(videoCamera);
        camera = Camera.getCamera();
        microphone = Microphone.getMicrophone();
        if (camera.muted) {
            trace("Camera Muted");
            Security.showSettings(SecurityPanel.CAMERA);
            camera.addEventListener(StatusEvent.STATUS, statusHandler);
        } else {
            startCamera();
        }

    }

    private function statusHandler(e:StatusEvent):void {
        if (e.code == "Camera.Unmuted") {
            trace("Camera Unmuted");
            startCamera();
            camera.removeEventListener(StatusEvent.STATUS, statusHandler);
        } else {
            trace("StatusEvent: " + e.code + " " + e.toString());
        }
    }

    private function startCamera():void {
        // here are all the quality and performance settings that we suggest
        camera.setMode(160, 120, 12, false);
        camera.setQuality(0, 75);
        camera.setKeyFrameInterval(24);
        microphone.rate = 11;
        microphone.setSilenceLevel(0);

        nc = new NetConnection();
        nc.connect("rtmp://localhost/live/");

        // get status information from the NetConnection object
        nc.addEventListener(NetStatusEvent.NET_STATUS, ncOnStatus); 
    }

    private function nsPublishOnStatus(infoObject:NetStatusEvent):void
    {
        trace("nsPublish: "+infoObject.info.code+" ("+infoObject.info.description+")");
    }

    private function ncOnStatus(infoObject:NetStatusEvent):void
    {
        trace("nc: "+infoObject.info.code+" ("+infoObject.info.description+")");
        nsPublish = new NetStream(nc);
        nsPublish.addEventListener(NetStatusEvent.NET_STATUS, nsPublishOnStatus);
        nsPublish.bufferTime = 0;
        nsPublish.publish("testing");
        // attach the camera and microphone to the server
        nsPublish.attachCamera(camera);
        nsPublish.attachAudio(microphone);
    }
}

我相当有信心这很简单。正如我在讨论如何发布到实时服务器时在无数网站上看到的那样。

任何帮助将不胜感激，我尝试在网络服务器上使用此代码来查看它是否只是本地安全设置，但事实并非如此。

在 Flash CS5 中调试应用程序时收到的日志：

尝试使用 URL D:\development\qanda\qandaHost.swf
[SWF] D:\development\qanda\qandaHost.swf 启动并连接到 Player - 解压后 3583 字节
摄像头静音
nc: NetConnection.Connect.Success （连接成功。 )
nsPublish：NetStream.Publish.Start（发布测试。）

下面是错误的：

Security.showSettings(SecurityPanel.**CAMERA**);

你应该写：

Security.showSettings(SecurityPanel.**PRIVACY**);

我没有将相机连接到视频上，因此我看不到自己——即使视频实际上是流式传输的。

private function startCamera():void {
    trace("Attempting to start camera");
    // here are all the quality and performance settings that we suggest
    camera.setMode(160, 120, 12, false);
    camera.setQuality(0, 75);
    camera.setKeyFrameInterval(24);
    videoCamera.attachCamera(camera);
    microphone.rate = 11;
    microphone.setSilenceLevel(0);
}
