本文介绍如何在FMS服务器上进行视频和语音的发布，通过简单的代码实现摄像头和麦克风的数据流传输，并演示了如何检测摄像头和麦克风的状态。

[b] 每天一点学FMS(二)文字+视频语音[/b]

FMS服务器的设置简单的仿照(一)就可以了,这段代码延续(一),加上了视频和语音发布,主要用到netstream.publish()方法,该方法也可以用于视频在线录制,除了检测摄相头和MIC状态的代码外，就增加了十几行的视频发布代码,有关摄相头和MIC的详细设置我并没有写,只是让大家看清楚它的工作原理,没有摄相头的朋友(我就没有摄相头)可以这样测试:打开麦克风说话,如果能听到回音就说明发布成功了

代码:
//建立与服务器的连接.
var sv_uri:String = "rtmp:/recordstream";
var my_nc:NetConnection = new NetConnection ();
my_nc.connect (sv_uri);
//新建共享对象;
my_nc.onStatus = function (thisObj:Object){
if (thisObj.code == "NetConnection.Connect.Success"){
info_txt.text = "连接服务器成功!!";
info_txt.textColor = 0x66CC00;
}
else{
info_txt.text = "连接服务器失败!!"
info_txt.textColor = 0xFF0000;
}
}
var user_rso:SharedObject = SharedObject.getRemote ("chat_rso", my_nc.uri, true);
user_rso.connect (my_nc);
//建立摄相头和麦克风对象
this.cam = Camera.get();
this.mic = Microphone.get();
videobox.attachVideo(this.cam);
videobox.attachAudio(this.mic);
send_ns = new NetStream(my_nc);
send_ns.attachVideo(this.cam);
send_ns.attachAudio(this.mic);
send_ns.publish("humorguy");
get_ns = new NetStream(my_nc);
get_ns.play("humorguy");
videobox2.attachVideo(get_ns);
//更新聊天内容
user_rso.onSync = function (){
chatOutput_txt.text += newline+this.data.chatname +":" + this.data.chatcontent;
chatOutput_txt.scroll = chatOutput_txt.maxscroll+1;//确保最新消息能显示在输出框里
}
//回车键发送聊天内容
function myOnKeyDown() {
if (Key.getCode() == 13) {
