又是我！我尝试使用 actionscript 开发我的聊天！我取得了一些成功！这是我的代码：
动作脚本：

javascript:
var name='myflash';
function getP2p(){
if(navigator.appName.indexOf("Microsoft")!=-1)return window[name];
else return document[name];

function p2pStartInit(){
try{getP2p().initConnection()}

return s;

function getRandom(min,max){

return Math.floor(r*(max-min)+min)
}
如果我在 initSendStream 函数中删除这些部分，一切正常：
recvVideos[subscriber.farID] = getVideoBox();
recvVideos[subscriber.farID].attachNetStream(subscriber);
我可以向任何我想要的同伴发送消息，我可以从我的网络摄像头看到视频。但是当我向任何人发送消息时，我也需要发送视频，我的问题就从这里开始了。
如果我用这两行代码编译应用程序，一切都会正常工作，直到我尝试连接到另一个对等方。这里出现错误 #1009，视频无法在对等方之间传输。我不明白我做错了什么。
还有另一个问题，可能是解决方案可能隐藏在这里。它一直出现。我在两个浏览器中测试这个聊天 - mozilla 和 opera。如果带有应用程序的页面首先在 opera 中加载，那么我可以在 opera 中看到来自网络摄像头的视频，而在 mozilla 中看不到它。如果 mozilla 页面首先加载，那么我可以在 mozilla 中看到视频，而在 opera 中看不到视频。为什么会这样？这真的让我很困惑！
所以请大家告诉我的代码有什么问题！
非常感谢您的帮助！
