as3摄像头

时间轴第一帧上敲以下代码就可以了：

//import fl.controls.Label;

//var camera:Camera = Camera.getCamera();
//trace(camera==null?"未检测到摄像头":"已安装了摄像头");

var W:int=stage.stageWidth;//场景的原始宽度
var H:int=stage.stageHeight;//场景的原始高度

stage.scaleMode=StageScaleMode.NO_SCALE;//舞台禁止缩放,但是好象没效果?

var video:Video;
var camera:Camera=Camera.getCamera();

if (camera==null) {
 trace("未检测到摄像头!"); 
 lbl1.text="未检测到摄像头!";
 btnCapture.visible=false;

} else {
 camera.addEventListener(ActivityEvent.ACTIVITY,activityHander);
 video=new Video(camera.width,camera.height);
 trace("视频宽度：" + camera.width + "，视频高度：" + camera.height);
 video.attachCamera(camera);
 //定位到水平中心点
 video.x = (W - video.width) /2;
 video.y=10;
 addChild(video);//加载到当前舞台中
 btnCapture.x = (W - btnCapture.width) /2;
 btnCapture.y=video.y+video.height+5;
 btnCapture.addEventListener(MouseEvent.CLICK,captureImage);

}

function activityHander(e:ActivityEvent):void {
 trace("activityHander:" + e);
}

var dp:DataProvider = new DataProvider();

function captureImage(e:MouseEvent):void {
 //trace("你点击了按钮");
 var bit:BitmapData=new BitmapData(video.width,video.height);
 bit.draw(video);
 var bmp:Bitmap=new Bitmap(bit);
 //bmp.y=btnCapture.y+btnCapture.height+10;
 //bmp.x = (W - bmp.width) /2;
 var d:Date = new Date();
 dp.addItem({label:"截图" + d.getFullYear() + d.getMonth() + d.getDay() + d.getHours() + d.getMinutes() + d.getSeconds() + d.getMilliseconds(),source:bmp});
 
 //addChild(bmp);
 tilelst1.dataProvider = dp;
}

stop();
