I want to receive live streaming from an IP camera using RTSP, I'm getting 'Can't play this video', and the following Exception:

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();
can't say I'm sure this is the problem, but I think it's because this camera software needs authentication, but if so, I don't know how to provide the authentication to it.
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)
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);
and this is a screenshots of login process headers and json data using firebug:
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:
public void setDataSource (Context context, Uri uri, Map<String, String> headers)
You must set the Authorization header:
Authorization: Basic _credentials_
_credentials_ is the RFC2045-MIME Base64 encoding of the username:password string.
