安卓媒体播放器 RTSP

Question

我正在尝试在 Android 设备上观看 RTSP 流媒体。但是如果服务器为流式传输设置密码，我的 Android 无法播放它。如果没有密码就可以了。这是我的代码。

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:
            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
public void onPrepared(MediaPlayer mp) {
    Log.e(AppConfig.TAG, "Media Player Prepared");
    m_mediaPlayer.start();
}

private void play() {
    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) {
                Log.e(AppConfig.TAG, "MEDIA ERROR");
            }
            else if(extra == MediaPlayer.MEDIA_ERROR_SERVER_DIED) {
                Log.e(AppConfig.TAG, "SERVER DIED ERROR");
            }
            else if(extra == MediaPlayer.MEDIA_ERROR_UNSUPPORTED) {
                Log.e(AppConfig.TAG, "MEDIA UNSUPPORTED");
            }
            else if(extra == MediaPlayer.MEDIA_ERROR_UNKNOWN) {
                Log.e(AppConfig.TAG, "MEDIA ERROR UNKOWN");
            }
            else if(extra == MediaPlayer.MEDIA_ERROR_NOT_VALID_FOR_PROGRESSIVE_PLAYBACK) {
                Log.e(AppConfig.TAG, "NOT VALID PROGRESSIVE PLAYBACK");
            }
            else {
                Log.e(AppConfig.TAG, String.valueOf(what));
                Log.e(AppConfig.TAG, String.valueOf(extra));
                Log.e(AppConfig.TAG, "ERROR UNKNOWN!");
            }
            return false;
        }
    });
}

private Map<String, String> createHeaders() {
    String videoUri = "rtsp://192.168.1.100:554/video/3gpp";

    Map<String, String> headers =  new HashMap<String, String>();
    String camUser = "guest";//m_sharedPref.getString(AppConfig.CAM_USER,"");
    String camPassword = "tseug";//m_sharedPref.getString(AppConfig.CAM_PASSWORD,"");
    String describe = "DESCRIBE " + videoUri + " RTSP/1.0";
    String accept = "application/sdp";
    String basicAuthValue = "";

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

我使用的网络摄像机是 D-link DCS 942L。我总是从摄像头收到 401 响应，但我的用户名和密码是正确的。这是我得到的日志

我想知道我的请求头是不是错了。这里有一篇文章 http://www.tuicool.com/articles/R7ZF7bF关于如何使用我使用的同一台相机通过身份验证播放 RTSP。如果有任何帮助或解释，我将不胜感激。

我和你一样在开发RTSP相关的代码，得出以下结论:

1. 使用 MediaPlayer 时，您的 RTSP_URL 可以是:rtsp://account:pass@192.168.0.x

2. 但是对于你提到的身份验证，如果你的相机使用 HTTP 基本身份验证，你需要在 http 请求中添加 header :，例如(我使用 OKHTTP 2.0):

   String basicAuth = Credentials.basic("账户", "通过");请求 request = new Request.Builder().url(url).header("Authorization", basicAuth).build();响应response = client.newCall(request).execute();

这对我有用!希望对您有所帮助。
