Adobe AIR的：如何播放本地的MP3文件？ [英] Adobe AIR: How to play local mp3 file?

问题描述

我测试的Adobe AIR使用Flex，我想通过一个打开文件对话框中发挥的MP3，我这样做：

I'm testing Adobe AIR with flex, and I wanted to play a mp3 via an open file dialog, I did that :

import flash.filesystem.*;
import flash.events.Event;
import flash.media.*;
import mx.core.SoundAsset;

public var loadedFile:File;
public var channel:SoundChannel;
public var song:SoundAsset;


private function loadFile():void {
 loadedFile = new File();
 loadedFile.browseForOpen("Open multimedia File");
 loadedFile.addEventListener(Event.SELECT, fileSelected);
}

private function fileSelected(event:Event):void {
 song = new SoundAsset()
 song.load(URLRequest(loadedFile.url));
 channel = song.play();
}

但是，当我试图打开一个文件，打开文件对话框关闭后，我得到这个错误：

But when I try to open a file, after the Open file dialog close, I get this error :

TypeError: Error #1034: Type Coercion failed: cannot convert "file:///C:/Users/Kedare/Music/05-Scene%20V%20~%20Prelude.mp3" to flash.net.URLRequest.

我找不到任何有关这对谷歌或其他文件，都让我觉得是有关的文档使用URL，而不是本地文件播放声音：（

I can't find anything related to that on Google or another documentation, all the docs I find is related to play a sound using URL and not Local files :(

什么可问题你知道吗？我该怎么办？

Any idea of what can be the problem ? What can I do ?

感谢您！

推荐答案

修改

song.load(URLRequest(loadedFile.url));

到

song.load(new URLRequest(loadedFile.url));
