Android getDuration for video gets different value on different versions

Question

I'm trying to play the following video on all devices. The problem is that with Android 4.1.2 the getDuration is 1476000 AKA 24:36 minutes. With Android 5.0.2 the getDuration returns 1546347 AKA 25:46 minutes.

So on Android 4.1.2 the real problem is that the video continues to play after "being finished". But the reality is that the video should have a getDuration like on Android 5.0.2. Does anyone here have any clue?

Code below:

private void crearVideoPlayer(String videoURL) {
    // Find your VideoView in your video_main.xml layout
    videoview = (VideoView) findViewById(R.id.VideoView);

    videoControls = new MediaController(this);
    videoview.setMediaController(videoControls);
    // Start the MediaController
    videoControls.setAnchorView(videoview);

    // Get the URL from String VideoURL
    Uri video = Uri.parse(videoURL);

    videoview.setOnCompletionListener(this);
    videoview.setOnTouchListener(this);

    videoview.setVideoURI(video);

    videoview.requestFocus();
    videoview.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
        // Close the progress bar and play the video
        public void onPrepared(MediaPlayer mp) {
            pDialog.dismiss();
            videoview.start();
        }
    });

}
