无法从IP cam接收RTSP直播

Question

我希望使用RTSP从IP摄像头接收实时流媒体，我正在＆＃39;无法播放此视频＆＃39; ，以及以下例外情况：

我使用以下方式：

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();

不能说我确定这是问题，但我认为这是因为这款相机软件需要验证，但如果是这样，我不知道如何提供身份验证。

使用带有setDataSource的MediaPlayer后，我得到以下例外：

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)

我不确定这是否与设置标题的方式有关：

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登录过程标题和json数据的屏幕截图：

Answer 1

如果身份验证机制是 HTTP基本身份验证，那么可能有办法设置所需的HTTP标头：MediaPlayer类的方法setDataSource采用{{1}标题的参数：

Map

您必须设置Authorization标题：

public void setDataSource (Context context, Uri uri, Map<String, String> headers)

Authorization: Basic _credentials_是_credentials_字符串的RFC2045-MIME Base64编码。
