我使用的方式如下：
I'm using the following way:
VideoView videoView = (VideoView) ((Activity) ctx).findViewById(R.id.videoView);
//add controls to a MediaPlayer like play, pause.
MediaController mc = new MediaController(ctx);
videoView.setMediaController(mc);
//Set the path of Video or URI
videoView.setVideoURI(Uri.parse("rtsp://192.168.30.108:554"));
//Set the focus
videoView.requestFocus();
不能说我敢肯定，这是一个问题，但我认为这是因为这台相机软件需要身份验证，但如果是这样，我不知道如何提供验证它。
使用MediaPlayer的用的setDataSource后，我得到了以下异常：
After using MediaPlayer with setDataSource, I'm getting the following Exception:
07-21 12:04:11.677: W/System.err(17714): java.io.IOException: Prepare failed.: status=0x1
07-21 12:04:11.677: W/System.err(17714): at android.media.MediaPlayer.prepare(Native Method)
我不知道如果这涉及到一个错误的方式在设置页眉或不：
I'm not sure if that related to a wrong way in setting the headers or not :
Uri uri = Uri.parse("rtsp://192.168.30.108:554");
Map<String , String> headres = new HashMap<String, String>();
headres.put("Authorization", "Basic ce0ca0f0864513c28c7be98f0f929be7b1f5db79"); //Also tried it without "Basic"
headres.put("encryption", "Default");
headres.put("mac", "9002A9D89200");
headres.put("random", "1715377261");
headres.put("realm", "Login to 90:02:a9:d8:92:00");
mediaPlayer.setDataSource(getApplicationContext(), uri, headres);
这是使用Firebug登录过程头和JSON数据的截图：

推荐答案
如果身份验证机制 HTTP基本身份验证，然后可能有办法设置所需的HTTP标头：在<一个href=\"http://developer.android.com/reference/android/media/MediaPlayer.html#setDataSource%28android.content.Context,%20android.net.Uri,%20java.util.Map%3Cjava.lang.String,%20java.lang.String%3E%29\"相对=nofollow> MediaPlayer的类有一个方法的setDataSource 走地图参数头文件：
If the authentication mechanism is HTTP basic authentication then there might be way to set the required HTTP header: the MediaPlayer class has a method setDataSource taking a Map parameter for headers:
公共无效的setDataSource（上下文的背景下，开放的URI，地图＆LT;字符串，字符串＆GT;头）
您必须设置授权头：
授权：基本_credentials _
_credentials _ 是的RFC2045-MIME Base64编码的用户名：密码字符串
