MediaPlayer的错误，当试图从流播放 [英] MediaPlayer error when attempt to play from a stream

问题描述

有谁知道是什么，第二个参数从这一错误中的的意思是（1，-2147483648）在MediaPlayer的？我不断地试图从URL流播放音频时收到它。我试图把它从一个扩展BaseExpandableListAdapter如果此事一类游戏。我已经审阅这篇文章<一个href="http://stackoverflow.com/questions/10795388/android-mediaplayer-error-mediaplayer-error1-2147483648-on-stream-from-inte">Android MediaPlayer的错误：MediaPlayer的错误（1，-2147483648）的流从互联网上但所有的答案是指流支持问题。这不是我的情况下，流支持的问题，因为我能够从同一个流播放音频，但只使用一个不同的类。这是我使用的演奏方法：

 私人无效startPlaying（字符串文件名）{
    媒体播放器=新的MediaPlayer（）;

    尝试 {
        如果（的FileInputStream！= NULL）{//从文件系统读取从一个FileInputStream文件（内部或外部存储）
            mediaPlayer.setDataSource（fileInputStream.getFD（））;
            Log.d（从设备，MediaPlayer正在玩）;

        } 其他 {
    //媒体播放器=新的MediaPlayer（）;
            mediaPlayer.setDataSource（getFilePath（））; //从URL中读取一个文件
            Log.d（从流的MediaPlayer播放）;
        }
        媒体播放器prepare（）。
        mediaPlayer.start（）;
        mediaPlayer.setOnCompletionListener（新CompletionListener（））;


    }赶上（IOException异常E）{
        Log.e（LOG_TAG，prepare（）失败）;
    }
}
 

解决方案

该错误通常是这些在这种情况一：

1. 在文件路径是错误的。不正确的目录或URL或URI中。
2. 在媒体文件是错误的，不兼容的格式。
3. 缺少权限

Does anybody know what does the second argument mean from this error (1, -2147483648) in MediaPlayer? I constantly receive it when attempting to play an audio from a url stream. I try to play it from a class that extends BaseExpandableListAdapter if that matter. I have already reviewed this post Android MediaPlayer error: MediaPlayer error(1, -2147483648) on Stream from internet however all the answers refers to the stream support issues. It's not a stream support issue in my case since I am able to play an audio from the same stream but just using a different class. This is a method that I'm using for playing:

private void startPlaying(String fileName) {
    mediaPlayer = new MediaPlayer();

    try {
        if (fileInputStream != null) {  // Read a file from a fileInputStream from a filesystem (EXTERNAL OR INTERNAL storage)
            mediaPlayer.setDataSource(fileInputStream.getFD());
            Log.d("MediaPlayer is playing", "from device");

        } else {
    //      mediaPlayer = new MediaPlayer();
            mediaPlayer.setDataSource(getFilePath());   // Read a file from a url
            Log.d("MediaPlayer is playing", "from stream");             
        }
        mediaPlayer.prepare();
        mediaPlayer.start();
        mediaPlayer.setOnCompletionListener(new CompletionListener());


    } catch (IOException e) {
        Log.e(LOG_TAG, "prepare() failed");
    }
}

解决方案

The error is usually one of these in this case:

1. File path is in error. Incorrect directory or Url or Uri found.
2. Media file is in error, incompatible format.
3. Missing permissions

Here's a good blog that outlines these situations and how to fix them:
