硬件条件:一个摄像头 一台FMS服务器即可
原理:摄像头实时采集视频源,然后推送到FMS服务器,其它客户从FMS上获取视频流。
需要做二个fla,一个用于向FMS服务端推送视频源(即发送端),一个用于从FMS服务器获取并播放视频(即接收端)
Server.fla关键代码:
代码语言:javascript复制var cam:Camera;
var vod:Video;
var intervalId:uint;
var intelvalTimes:uint=0;
var isWorked=false;
var nc:NetConnection;
var ns:NetStream;
btnPublish.addEventListener(MouseEvent.CLICK,btnPublishClick);
lblMsg.text = "连接好摄像头后,n点击下面的按钮"
//摄像头有活动时,被触发
function camActivityHandler(e:ActivityEvent) {
trace(e);
if (!isWorked) {
intervalId=setInterval(checkCallBack,100);
}
}
function checkCallBack():void {
intelvalTimes =1;
trace(intelvalTimes);
if (cam.currentFPS>0) {
lblMsg.text="摄像头工作正常!";
isWorked=true;
clearInterval(intervalId);
ns.publish("myCamera", "live");
//同时处理本地播放
vod = new Video();
vod.attachCamera(cam);
vod.height=cam.height;
vod.width=cam.width;
vod.x = 45;
vod.y = 15;
addChild(vod);
} else {
if (intelvalTimes>=10) {//持续检测2秒,仍然无图象的话,认为"设备无法使用(占用中)"
lblMsg.text="设备无法使用(有可能被占用)";
clearInterval(intervalId);
}
}
}
//用户选择"同意"或"不允许"使用摄像头时触发
function statusHandler(e:StatusEvent) {
trace(e);
if (e.code=="Camera.Muted") {
lblMsg.text="您不允许使用摄像头!";
} else if (e.code == "Camera.Unmuted") {
lblMsg.text="摄像头视频获取中...";
}
}
//推送按钮点击事件
function btnPublishClick(e:MouseEvent) {
nc = new NetConnection();
nc.addEventListener(NetStatusEvent.NET_STATUS, NetStatusHandler);
nc.connect("rtmp://fms服务器ip地址/camlive");
}
//连接状态处理代码
function NetStatusHandler(event:NetStatusEvent):void {
trace(event.info.code);
if (event.info.code=="NetConnection.Connect.Success") {
cam=Camera.getCamera();
if (cam==null) {
this.lblMsg.text="未安装摄像头!";
return;
}
cam.addEventListener(StatusEvent.STATUS, statusHandler);
cam.addEventListener(ActivityEvent.ACTIVITY,camActivityHandler);
ns=new NetStream(nc);
ns.attachCamera(cam);
}
}
Client.fla关键代码:
代码语言:javascript复制var nc:NetConnection;
var ns:NetStream;
var vod:Video;
btnReceive.addEventListener(MouseEvent.CLICK,function(){
nc = new NetConnection();
nc.addEventListener(NetStatusEvent.NET_STATUS, NetStatusHandler);
nc.connect("rtmp://fms服务器ip地址/camlive");
})
//连接状态处理代码
function NetStatusHandler(event:NetStatusEvent):void {
trace(event.info.code);
if (event.info.code=="NetConnection.Connect.Success") {
lblMsg.text = "正在获取视频..."
ns=new NetStream(nc);
ns.addEventListener(NetStatusEvent.NET_STATUS,nsNetStatusHandler);
ns.play("myCamera");
vod = new Video();
vod.x=45;
vod.y=15;
vod.height=120;
vod.width=160;
vod.attachNetStream(ns);
addChild(vod);
}
}
function nsNetStatusHandler(e:NetStatusEvent){
trace(e.info.code);
}
