Android 安卓：韩元'；不播放rtp流

我想制作一个从服务器播放声音的应用程序。 从internet接收和播放是可行的，但对于我的JMF程序，它不起作用（错误（-38,0））

以下是我的应用程序代码片段：

MediaPlayer mPlayer = new MediaPlayer();
    // String url
    // ="http://programmerguru.com/android-tutorial/wp-content/uploads/2013/04/hosannatelugu.mp3";
    String url = "rtp://192.168.32.29:22222/audio/16";
    mPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);

    AudioManager audioManager = (AudioManager) this
            .getSystemService(Context.AUDIO_SERVICE);
    audioManager.setStreamVolume(AudioManager.STREAM_MUSIC, volume, volume);

    try {
        mPlayer.setDataSource(url);
    } catch (IllegalArgumentException e) {
        Toast.makeText(getApplicationContext(),
                "You might not set the URI correctly!", Toast.LENGTH_LONG)
                .show();
    } catch (SecurityException e) {
        Toast.makeText(getApplicationContext(),
                "You might not set the URI correctly!", Toast.LENGTH_LONG)
                .show();
    } catch (IllegalStateException e) {
        Toast.makeText(getApplicationContext(),
                "You might not set the URI correctly!", Toast.LENGTH_LONG)
                .show();
    } catch (IOException e) {
        e.printStackTrace();
    }

    try {
        mPlayer.prepare();
    } catch (IllegalStateException e) {
        Toast.makeText(getApplicationContext(),
                "You might not set the URI correctly!", Toast.LENGTH_LONG)
                .show();
    } catch (IOException e) {
        Toast.makeText(getApplicationContext(),
                "You might not set the URI correctly!", Toast.LENGTH_LONG)
                .show();
    }

    mPlayer.start();

当我使用“”时，它起作用，但是“rtp://192.168.32.29:22222/audio/16“向我发送错误（-38,0）

有人能帮我吗？ 谢谢
