我如何附上相机Spark.components.VideoDisplay

问题描述

我在使用Flash Builder和创建Spark应用的Flex项目，将视频流从本地摄像头。如果我使用 mx.controls.VideoDisplay当;是没有问题的，因为它有的attachCamera（摄像头）方法。但是，星火的的VideoDisplay 组件没有该方法。我知道我可以使用内部的火花应用程序MX控制，但我想知道的：

I'm using Flash Builder and created a spark-application Flex project that will stream video from the local camera. If I use mx.controls.VideoDisplay; there is no problem since it has attachCamera(camera) method. But Spark's VideoDisplay component does not have that method. I know I can use mx controls inside a Spark app but I want to know:

• 是什么 spark.components.VideoDisplay 和 mx.controls.VideoDisplay当？
• 如何连接相机 spark.components.VideoDisplay ？
• 有什么好处，如果我去火花（因为它是新的，以MX库）？

• What is the real difference between spark.components.VideoDisplay and mx.controls.VideoDisplay?
• How do I attach camera to spark.components.VideoDisplay?
• Is there any advantages if I go with spark (since it's newer to mx library)?

感谢。

修改：在这个文件中提到：的 Flex 4.0开始，Adobe建议您使用spark.components.VideoPlayer类来替代此类（MX。 controls.VideoDisplay）的

EDIT: In the documentation this is mentioned: "Starting with Flex 4.0, Adobe recommends that you use the spark.components.VideoPlayer class as an alternative to this class. (mx.controls.VideoDisplay)"

推荐答案

下面是具体得到这个工作：

Here are the specifics to get this working:

import mx.events.FlexEvent;

import org.osmf.net.StreamType;

import spark.components.mediaClasses.DynamicStreamingVideoItem;
import spark.components.mediaClasses.DynamicStreamingVideoSource;

private var _cam:DynamicStreamingVideoSource =  new DynamicStreamingVideoSource();
private var _dynVideoSource:DynamicStreamingVideoSource;

protected function application1_creationCompleteHandler(event:FlexEvent):void
{

    _dynVideoSource=new DynamicStreamingVideoSource();

    var videoItems:Vector.<DynamicStreamingVideoItem>;
    videoItems=new Vector.<DynamicStreamingVideoItem>();
    videoItems[0]=new DynamicStreamingVideoItem();

    _dynVideoSource.host= "";
    _dynVideoSource.streamType=StreamType.LIVE;
    _dynVideoSource.streamItems=videoItems;

    mycam.source=_dynVideoSource;

    var cam:Camera = Camera.getCamera(); //Camera.names[0]);
    cam.setMode(640, 480, 15);
    cam.setQuality(0, 80);
    mycam.videoObject.attachCamera(cam); 
}
