Question

我正在尝试使用flash / as3拍摄静态照片并按照the example from Adobe

因此我的AS文件中的代码是

package  {
    import flash.desktop.NativeApplication;
    import flash.display.Loader;
    import flash.display.MovieClip;
    import flash.display.StageAlign;
    import flash.display.StageScaleMode;
    import flash.events.ErrorEvent;
    import flash.events.Event;
    import flash.events.IOErrorEvent;
    import flash.events.MediaEvent;
    import flash.media.CameraUI;
    import flash.media.MediaPromise;
    import flash.media.MediaType;

    public class CameraUIStillImage extends MovieClip{

        private var deviceCameraApp:CameraUI = new CameraUI();
        private var imageLoader:Loader; 

        public function CameraUIStillImage() {
            this.stage.align = StageAlign.TOP_LEFT;
            this.stage.scaleMode = StageScaleMode.NO_SCALE;

            if( CameraUI.isSupported )
            {
                trace( "Initializing camera..." );

                deviceCameraApp.addEventListener( MediaEvent.COMPLETE, imageCaptured );
                deviceCameraApp.addEventListener( Event.CANCEL, captureCanceled );
                deviceCameraApp.addEventListener( ErrorEvent.ERROR, cameraError );
                deviceCameraApp.launch( MediaType.IMAGE );
            }
            else
            {
                trace( "Camera interface is not supported.");
            }
        }

        private function imageCaptured( event:MediaEvent ):void
        {
            trace( "Media captured..." );

            var imagePromise:MediaPromise = event.data;

            if( imagePromise.isAsync )
            {
                trace( "Asynchronous media promise." );
                imageLoader = new Loader();
                imageLoader.contentLoaderInfo.addEventListener( Event.COMPLETE, asyncImageLoaded );
                imageLoader.addEventListener( IOErrorEvent.IO_ERROR, cameraError );

                imageLoader.loadFilePromise( imagePromise );
            }
            else
            {
                trace( "Synchronous media promise." );
                imageLoader.loadFilePromise( imagePromise );
                showMedia( imageLoader );
            }
        }

        private function captureCanceled( event:Event ):void
        {
            trace( "Media capture canceled." );
            NativeApplication.nativeApplication.exit();
        }

        private function asyncImageLoaded( event:Event ):void
        {
            trace( "Media loaded in memory." );
            showMedia( imageLoader );    
        }

        private function showMedia( loader:Loader ):void
        {
            this.addChild( loader );
        }

        private function cameraError( error:ErrorEvent ):void
        {
            trace( "Error:" + error.text );
            NativeApplication.nativeApplication.exit();
        }
    }
}

在我的时间轴上我正在打电话

 import CameraUIStillImage; 
 var cameraUIStillImage:CameraUIStillImage = new CameraUIStillImage();
 addChild(cameraUIStillImage);

这会产生错误

未找到类型或不是编译时常量：MediaType

我在谷歌上发现的所有这类问题的解决方案都没有对我有所帮助。任何人都知道什么是错的？：）

谢谢！

Answer 1

MediaType.IMAGE适用于AIR＆gt; = 2.5，因此您必须为该目标进行部署，否则它将无法正常工作。
