Android媒体播放器RTSP

Question

我正试着在Android设备上观看RTSP流媒体。但是，如果服务器为流设置密码，我的Android就不能播放它。如果没有密码就没问题了。这是我的密码。

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:

            break;
    }
}

}

        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() {

    if (camUser != "") {
        String credentials = camUser + ":" + camPassword;
        byte[] bytes = credentials.getBytes();
        int flags = Base64.URL_SAFE|Base64.NO_WRAP;
        basicAuthValue = "Basic " + Base64.encodeToString(bytes, flags);
        headers.put("Authorization", basicAuthValue);
    }

    headers.put("Request", describe);
    headers.put("Accept", accept);

    Log.i(AppConfig.TAG, "Accept: " + accept);
    return headers;
}

}

我使用的IP摄像头是D链接DCS 942 L。我总是从相机得到401响应，但我的用户名和密码是正确的。这是我拿到的原木

我想知道我的请求头是否错了。这里有一篇关于如何使用我使用的相机进行身份验证的http://www.tuicool.com/articles/R7ZF7bF的文章。我将非常感谢任何帮助或解释。

我和您一样正在开发RTSP相关代码，我发现了以下结论：

1. 使用MediaPlayer时，您的RTSP_URL可以是:rtsp://RTSP_URL:pass@192.168.0.x
2. 但是通过您提到的身份验证，如果您的相机使用HTTP，则需要在http请求：、ex(我使用OKHTTP2.0)中添加报头： 字符串basicAuth = Credentials.basic("account"，"pass")；请求请求=新的basicAuth).build()；响应响应=client.newCall(请求).execute()；

这对我有用！希望这对你有帮助。
