Я пытаюсь смотреть потоковую передачу RTSP на устройстве Android. Но если сервер установил пароль для потоковой передачи, мой Android не сможет воспроизвести его. Если без пароля это нормально. Вот мои коды.

public class VideoFragment extends Fragment implements View.OnClickListener, SurfaceHolder.Callback, MediaPlayer.OnPreparedListener {


VideoView m_videoView;
SurfaceView m_surfaceView;
SurfaceHolder m_surfaceHolder;
MediaPlayer m_mediaPlayer;
SharedPreferences m_sharedPref;
Boolean m_videoStarted;

public VideoFragment() {
    // Required empty public constructor
}


@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
                         Bundle savedInstanceState) {
    View view = inflater.inflate(R.layout.fragment_video, container, false);
    m_sharedPref = this.getActivity().getSharedPreferences(MainActivity.class.getSimpleName(), Context.MODE_PRIVATE);
    m_surfaceView = (SurfaceView) view.findViewById(R.id.surfaceView);
    m_surfaceHolder = m_surfaceView.getHolder();
    m_surfaceHolder.addCallback(this);
    m_surfaceHolder.setFixedSize(320, 240);
    m_videoStarted = false;
    ToggleButton togglePlay = (ToggleButton) view.findViewById(R.id.toggleVideo);
    togglePlay.setOnClickListener(this);
    return view;
}


@Override
public void onClick(View v) {
    switch (v.getId()) {
        case R.id.toggleVideo:
            if(m_videoStarted == false) {
                play();
                m_videoStarted = true;
            }
            else {
                m_mediaPlayer.reset();
            }

            break;
        default:
            Log.i(AppConfig.TAG, "DEFAULT");
            break;
    }
}

@Override
public void surfaceCreated(SurfaceHolder holder) {
    Log.e(AppConfig.TAG, "surfaceCreated");

}

@Override
public void surfaceChanged(SurfaceHolder holder, int format, int width, int height) {

}

@Override
public void surfaceDestroyed(SurfaceHolder holder) {
    m_mediaPlayer.release();
}

@Override

    Log.e(AppConfig.TAG, "Media Player Prepared");
    m_mediaPlayer.start();

    if(m_mediaPlayer == null) {
        m_mediaPlayer = new MediaPlayer();
    }
    setErrorListener();
    m_mediaPlayer.setDisplay(m_surfaceHolder);
    m_mediaPlayer.setOnPreparedListener(this);
    try {
        Map<String, String> headers =  createHeaders();
        String videoUri = "rtsp://192.168.1.100:554/video/3gpp";
        Log.i(AppConfig.TAG, "Video URI: " + videoUri);
        m_mediaPlayer.setDataSource(getActivity(), Uri.parse(videoUri), headers);
        m_mediaPlayer.prepareAsync();
    } catch (IOException e) {
        e.printStackTrace();
    }
}

private void setErrorListener() {
    m_mediaPlayer.setOnErrorListener(new MediaPlayer.OnErrorListener() {
        @Override
        public boolean onError(MediaPlayer mp, int what, int extra) {
            if(extra == MediaPlayer.MEDIA_ERROR_IO) {

}

}

Я использую IP-камеру D-link DCS 942L. Я всегда получаю 401 ответ от камеры, но мои имя пользователя и пароль верны. Вот журнал, который я получил

Интересно, если мой заголовок запроса неправильный. И здесь есть статьяhttp://www.tuicool.com/articles/R7ZF7bF о том, как играть в RTSP с аутентификацией, используя ту же камеру, которую я использую. Я буду очень благодарен за любую помощь или объяснение.
