我试图在Android设备上观看RTSP流媒体。但是如果服务器为我的Android设置了密码而无法播放它。如果没有密码就行了。这是我的代码。
public class VideoFragment extends Fragment implements View.OnClickListener, SurfaceHolder.Callback, MediaPlayer.OnPreparedListener {
VideoView m_videoView;
SurfaceView m_surfaceView;

}

Bundle savedInstanceState) {

m_surfaceView = (SurfaceView) view.findViewById(R.id.surfaceView);
m_surfaceHolder = m_surfaceView.getHolder();

togglePlay.setOnClickListener(this);

我使用的IP摄像机是D-link DCS 942L。我总是得到相机的401响应，但我的用户名和密码是正确的。这是我得到的日志

我想知道我的请求标头是否错误。这里有一篇文章http://www.tuicool.com/articles/R7ZF7bF关于如何使用我使用的相同相机使用身份验证来播放RTSP。 我将非常感谢任何帮助或解释。
答案 0 :(得分：2)
我和您一样开发与RTSP相关的代码，我得出以下结论：
但是根据您提到的身份验证，如果您的相机使用HTTP基本身份验证，则需要在http request：，ex（我使用OKHTTP 2.0）中添加标头：
String basicAuth = Credentials.basic（＆＃34; account＆＃34;，＆＃34; pass＆＃34;）; 请求请求= new Request.Builder（）。url（url）.header（＆＃34; Authorization＆＃34;，basicAuth）.build（）; 响应响应= client.newCall（请求）.execute（）;
这对我有用！希望它对你有所帮助。
