Android MediaPlayer错误:从internet上传输的MediaPlayer错误(1，-2147483648)。

I'm trying to stream audio from a URL. The code works fine with other URLs, but in one of those it fails in the OnPrepared method, returning this error code: (1, -2147483648). I've read some people saying it's because of permissions, but it's a remote file, so I can't set permissions. I've tried the URL with other apps like VLC and iTunes, and it's working fine. My code is here:

我正在尝试从一个URL传输音频。这段代码可以很好地处理其他url，但是在onprepare方法中失败了，返回这个错误代码:(1，-2147483648)。我读过一些人说这是因为权限，但这是一个远程文件，所以我不能设置权限。我已经在VLC和iTunes等应用程序上试用过这个URL，它运行得很好。我的代码是:

private void prepareradio() {
    player = new MediaPlayer();
    player.setAudioStreamType(MODE_WORLD_READABLE);
    try {
        player.setDataSource(url);

    } catch (IllegalArgumentException e) {
        e.printStackTrace();
    } catch (IllegalStateException e) {
        e.printStackTrace();
    } catch (IOException e) {
        e.printStackTrace();
    }

    player.setOnErrorListener(new OnErrorListener(){
        public boolean onError(MediaPlayer arg0, int arg1, int arg2) {
            Toast.makeText(getApplicationContext(),"An error happened while preparing radio",Toast.LENGTH_LONG).show();
            prepareradio();
            playe.setEnabled(true);
            hidenot();
            return false;
        }
    });

If you are testing on devices earlier than Android 3.1 you might not be able to play AACP (as seen on the info page for your stream (AAC+) streams.

如果您在比Android 3.1更早的设备上进行测试，您可能无法使用AACP(在您的流(AAC+)流的信息页上看到)。

Info page for your stream:

I was also getting the same error on Froyo & Gingerbread. In higher Androids the same video played well. Finally after a lot of research, tried changing the Https Url to Http Url & Bingo. It resolved my issue. I was using amazon S3 server so that simply replacing the "https" in url with "http" was sufficient.

我在Froyo & Gingerbread上也犯了同样的错误。在高级机器人中，同样的视频播放得很好。经过大量研究之后，尝试将Https Url更改为Http Url & Bingo。它解决了我的问题。我使用的是amazon S3服务器，因此只需将url中的“https”替换为“http”就足够了。

  videoUrl= videoUrl.replaceFirst("https", "http");

PS: For supporting older versions if you are using H.264 make sure videos are Baseline encoded.

PS:如果你正在使用H.264，为了支持旧版本，请确保视频是基线编码的。

As I can see, this stream is not supported by mediaPlayer. Android supports AAC LC/LTP but your stream is aacp. I think this may be the root cause of your problem.

如我所见，这个流不是由mediaPlayer支持的。Android支持AAC LC/LTP，但是你的流是aacp。我认为这可能是你的问题的根本原因。
