Flash Builder 初试（三） 使用摄像头

本程序演示了，如何调用本地摄像头，并显示在FLASH中

            import flash.media.Camera;
            
            import mx.events.FlexEvent;
            
            private var camera:Camera;
            private var video:Video;
            
            protected function btnCamera_clickHandler(event:MouseEvent):void
            {
                // TODO Auto-generated method stub
                if(Camera.isSupported==true)
                {
                    camera=Camera.getCamera();
                    camera.setMode(320,240,15,true);
                    sve.width=camera.width;
                    sve.height=camera.height;
                    video=new Video(camera.width,camera.height);
                    video.attachCamera(camera);
                    sve.addChild(video);
                    this.lab_info.text="摄像头 ["+camera.name+"] 已经打开";
                }
                else
                {
                    this.lab_info.text="系统不支持摄像头！";
                }
            }

    <s:SpriteVisualElement id="sve" x="10" y="39" width="100" height="100"/>
    <s:Button id="btnCamera" x="10" y="10" label="打开摄像头" click="btnCamera_clickHandler(event)"/>
    <s:Label id="lab_info" x="98" y="19"/>
