android rtsp live stream - "Can't play this video"

public class MainActivity extends Activity
{
VideoView vv;
@Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
vv = (VideoView)findViewById(R.id.videoView);

Uri uri;
uri=Uri.parse("rtsp://user:pass@192.168.x.x:554/cam/realmonitor?channel=1&subtype=1");
vv.setVideoURI(uri);
vv.start();
}
}


I am using the above code, trying to play my IP live camera stream. The used URI works when used in VLC player. I have Internet permissions set inside my manifest too. But when I run the app on my emulator, or live device, I get the "Can't play this video" error.

The error that pops up in logcat is:

08-31 09:21:15.602 2487-2487/package D/MediaPlayer: Couldn't open file on client side, trying server side
08-31 09:21:15.612 2487-2503/package W/MediaPlayer: info/warning (701, 0)
08-31 09:21:15.666 2487-2502/package E/MediaPlayer: error (1, -2147483648)
08-31 09:21:15.725 2487-2487/package E/MediaPlayer: Error (1,-2147483648)
08-31 09:21:15.725 2487-2487/package D/VideoView: Error: 1,-2147483648


I have tried setting it up with media player aswell:

public class MainActivity extends Activity implements MediaPlayer.OnPreparedListener, SurfaceHolder.Callback
{
final static String USERNAME = "user";
final static String PASSWORD = "pass";
final static String RTSP_URL = "rtsp://192.168.x.x:554/cam/realmonitor?channel=1&subtype=00";

private MediaPlayer _mediaPlayer;
private SurfaceHolder _surfaceHolder;

@Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_NO_TITLE);
Window window = getWindow();
window.setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
window.setBackgroundDrawableResource(android.R.color.black);
setContentView(R.layout.activity_main);
SurfaceView surfaceView = (SurfaceView) findViewById(R.id.surfaceView);
_surfaceHolder = surfaceView.getHolder();
_surfaceHolder.addCallback(this);
_surfaceHolder.setFixedSize(320, 240);
}
@Override
public void surfaceChanged(SurfaceHolder sh, int f, int w, int h) {}
@Override
public void surfaceCreated(SurfaceHolder sh) {
_mediaPlayer = new MediaPlayer();
_mediaPlayer.setDisplay(_surfaceHolder);
Context context = getApplicationContext();
Map<String, String> headers = getRtspHeaders();
Uri source = Uri.parse(RTSP_URL);
try {
_mediaPlayer.setDataSource(context, source, headers);
_mediaPlayer.setOnPreparedListener(this);
_mediaPlayer.prepareAsync();
}
catch (Exception e) {}
}
@Override
public void surfaceDestroyed(SurfaceHolder sh) {
_mediaPlayer.release();
}
private Map<String, String> getRtspHeaders() {
Map<String, String> headers = new HashMap<String, String>();
String basicAuthValue = getBasicAuthValue(USERNAME, PASSWORD);
headers.put("Authorization", basicAuthValue);
return headers;
}
private String getBasicAuthValue(String usr, String pwd) {
String credentials = usr + ":" + pwd;
int flags = Base64.URL_SAFE | Base64.NO_WRAP;
byte[] bytes = credentials.getBytes();
return "Basic " + Base64.encodeToString(bytes, flags);
}
@Override
public void onPrepared(MediaPlayer mp) {
_mediaPlayer.start();
}
}


the above code has been taken from here
but none of them work.
I've also tried the Vitamio library with no results. Nothing I do seems to be working.

Am I missing any small details somewhere? I'm assuming the URI is fine since that works in VLC player just fine. At some point the emulator was also giving a "java.io.FileNotFoundException: No content provider", but no longer.

At one point, I was thinking that maybe the authentication is a problem, so I streamed the IP camera using VLC, without user/pass, and tried to connect, but that didn't work either, so I'm assuming it is successfully authenticating.

I have also tried passing the url in as "rtsp://user:pass@192.168.x.x:554/", that also works in VLC player. But not in my app.

I have tried everything I was able to find, with no success. If anyone is able to help out, would be much appreciated!

Edit 1: The VideoView has been able to successfully play pre-recorded clips such as "rtsp://mpv.cdn3.bigCDN.com:554/bigCDN/definst/mp4:bigbuckbunnyiphone_400.mp4"
same with vitamio and mediaplayer.

Answer

You are trying to play the video inVideoView. Unfortunately VideoView does not support videos which try to play using RTSP protocol.

You can use a library called Vitamino to play videos using RTSP. You can check out their demo here
