我正在尝试在两个人之间构建一个视频会议应用程序。我面临的问题是我将视频和麦克风附加到我的流中并发布它。第一次通话时，音频与视频一起传输，但是当我结束通话并再次通话时，我可以看到只有视频，流中没有音频传​​输。我调试了应用程序，麦克风和视频正在附加到流中。无法弄清楚如何结束这一切。任何帮助将不胜感激。这是我的一些代码。谢谢你。

camera = Camera.getCamera();
mic = Microphone.getMicrophone();
mic.setLoopBack(false); // prevent input from being routed back to local speakers - helps reduce feedback in some conditions
mic.setUseEchoSuppression(true);

camera.setMode(320,240,15);
camera.setQuality(65536,75);

// setup out going stream
var conn:NetConnection = Connection.getConnection().conn;

outStream = new NetStream(conn);
outStream.attachAudio(mic);
outStream.attachCamera(camera);
outStream.publish(appState.userProfile.username);

// setup in coming stream
inStream = new NetStream(conn);
inStream.play(appState.callingUser.username);
inStream.addEventListener(AsyncErrorEvent.ASYNC_ERROR, asyncErrorHandler);
//inStream.addEventListener(NetStatusEvent.NET_STATUS, netStatusHandlerForInStream);

这是 endCall 函数。

if(camera!=null || mic != null)
{
    outStream.attachCamera(null);
    outStream.attachAudio(null);
    outVideo.attachCamera(null);
    inStream.close();
    outStream.close();
    camera = null;
    mic = null;
    inVideo = null;
    outVideo = null;

    inStream = null;
    outStream = null;

    if (newStream)
    {
        newStream.close();
        newStream = null;
    }
}
