我正在尝试从我的 PC 上的 VLC 流式传输到在 Android 4.0.3 上运行的 Android 设备，但不知何故它无法正常工作，我搜索了互联网，我的错误意味着我使用了错误的格式。但是我已经得到了正确的格式，这个错误不应该发生。所以我希望你们能帮助我解决问题所在。

MediaPlayer player;
SurfaceHolder holder;
SurfaceView surfaceView;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    surfaceView = (SurfaceView) findViewById(R.id.rtspStream);
    holder = surfaceView.getHolder();
    holder.addCallback(this);
    player = new MediaPlayer();
    player.setOnErrorListener(this);
}

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.activity_main, menu);
    return true;
}
@Override
public void surfaceChanged(SurfaceHolder arg0, int arg1, int arg2, int arg3) {
    // TODO Auto-generated method stub

}
@Override
public void surfaceCreated(SurfaceHolder arg0) {
    try
    {
        if(holder.equals(holder))
        {
            player.setDataSource(this,Uri.parse("rtsp://192.168.0.3:8080/test.sdp"));
            player.setDisplay(holder);          
            player.prepare();
            player.start();
        }
    }
    catch(Exception e){
        Log.e("MEDIA", e.toString());
    }
}
@Override
public void surfaceDestroyed(SurfaceHolder arg0) {
    // TODO Auto-generated method stub  
}
@Override
public boolean onError(MediaPlayer arg0, int arg1, int arg2) {
    if(arg0.equals(player)){
        if(arg1 == MediaPlayer.MEDIA_ERROR_UNKNOWN){
            Log.d("onError","extra "+arg2);
        }

    }
    return false;
}

这是我的测试课。我的 Logcat 看起来像这样

我在终端中运行 VLC：

vlc -vvv testing.mp4 --sout '#rtp{dst=192.168.0.7,port=1234,sdp=rtsp://192.168.0.3:8080/test.sdp}'

从互联网流式传输时，使用 prepareAsync 而不是 prepare 并从 onPrepared 方法调用 start：

player.setOnPreparedListener( new StreamPlayerListener() );         
player.prepareAsync();

和 StreamPlayerListener 类：

private class StreamPlayerListener implements OnPreparedListener {

    @Override
    public void onPrepared(MediaPlayer mp) {
        player.start();
    }
}
