Android-fullscreen seamless video loop in background

I am created an Android app thta needs to have a fullscreen seemless video loop playing in the background. By 'in the background' I mean that there will be buttons on top of the video.
I've read these threadw already
playback video full screen
Integrating video file in android app as app background
but I'm still confused about the following
1 Is the mediaplayer needed for video playback?
2 Will using OnCompletionListener create a 'seamless' loop or will there be a 'hiccup' as the video loops?

Use the setOnPreparedListener to tell the MediaPlayer to loop and start
videoview.setOnPreparedListener(new OnPreparedListener()
{
#Override
public void onPrepared(MediaPlayer mp) {
mp.setLooping(true);
mp.start();
}
});
This is seemless on some devices, but can cause a frame or two of stutter on others :/

Pause/Stop MediaPlayer Android at given time programmatically

I researched a little bit, but couldn't find any solutions to this problem:
I would like to play a MediaPlayer and pause/stop it at a given time.. (ie: play from second 6 to second 17).
I know that I can set its starting point with seekTo() method, but can I pause/stop it from playing by setting an end point (of course, before reaching the file end limit)?

There are different ways you could do this, here's one:
int startFrom = 6000;
int endAt = 11000;
MediaPlayer mp;
Runnable stopPlayerTask = new Runnable(){
#Override
public void run() {
mp.pause();
}};
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mp = MediaPlayer.create(this, R.raw.my_sound_file);
mp.seekTo(startFrom);
mp.start();
Handler handler = new Handler();
handler.postDelayed(stopPlayerTask, endAt);
}
The mediaplayer will start playing 6 seconds in and pause it 11 seconds after that (at second 17).

I think you can create Timer and call seekTo() directly from its task. Then call stop()/pause() inside of that Timer Task.
Maybe this post will be helpfull for you.
Or you can use handler for this task, like Ken Wolf shows you.
Best wishes.

You can use CountDownTimer
new CountDownTimer(30000, 1000) {
public void onTick(long millisUntilFinished) {
}
public void onFinish() {
mp.stop;
mp.relese();
}
}.start();

I know this already has an answer but here is an alternative for anyone wanting to do this efficiently for a video with controls.
I saw a different answer that involved constantly checking the position.
Note that this assumes that you do not need a lot of different portions of one video. Even in that case I suggest to follow the below.
If you only need to play a portion of the video and want it to end somewhere, then why not just use free video editing software and clip the end? You can still start it from anywhere using seekTo() but this way you don't have to waste resources checking for a certain position (video with controls).
If you do not have video player controls the accepted answer will work. But if you do have player controls then it would not since a user could pause and play the video.

There's a time difference between videoView.start() and video prepared to play depend on video format, those time difference is probably more than 10 frames.
so the best way to do is to start the timer inside OnPreparedListener to minimise the time difference, or even more to get the current playing duration and set a postDelayed timer at that point.

Android Vitamio weired buffering on progressive download stream

I try to stream (progressive e.g: http://server.com/video.mp4)
when i use the standard google mediaplayer (VideoView from android package) and register an onBufferingUpdateListener then i get the bufferpercentage that refers to the download state of the hole video. This player has also a loading view where i can see the buffer state.
This bufferpercentage and view shows me how much of the video has been downloaded.
Now when i use the Vitamio player, the onBufferingUpdateListener shows me after a few seconds 99 percent of buffering and there is no loading view too. And when i pause the playback it stops buffering immediately instead of continue buffering like the google videoview does. This is very usefull if you have a slow http stream.
Is there a way to make the vitamio-videoplayer buffer the videofiles in the same way as the google videoplayer does?
thank you
daniel

Sorry i posted that question as wrong user. Here the Answer of what i tried:
VideoView (android default - just plays few video formats) from inside the android.widget and from io.vov.vitamio.widget (vitamio - plays most video formats) package has the same structure. In both you can register an OnBufferingUdateListener that returns the bufferstate in percent:
videoview.setOnBufferingUpdateListener(new io.vov.vitamio.MediaPlayer.OnBufferingUpdateListener() {
public void onBufferingUpdate(io.vov.vitamio.MediaPlayer mp, int i) {
Log.v(TAG, "Buffer percentage done: "+i);
}
});
or with the android default VideoView:
videoview.setOnBufferingUpdateListener(new android.media.MediaPlayer.OnBufferingUpdateListener() {
public void onBufferingUpdate(android.media.MediaPlayer mp, int i) {
Log.v(TAG, "Buffer percentage done: "+i);
}
});
If i use android.widget.VideoView the buffer percentage slowly increases until it reaches 100% - The video file has been downloaded completely. And it continues updating BufferingUpdate when i press the pause button.
When i use io.vov.vitamio.widget.VideoView the percentage reaches 100% within seconds. Then the video starts and the OnBufferingUpdateListener never gets called again (when i call getBufferPercentage it is always at 99 percent. That seems to be the reason). And as i sayed: It seems to stop buffering when i press the pause button.
I think the buffering works different in vitamio. But that's crap. Especially when i stream videos from the web and the video datarate is higher than the download speed i need to prebuffer the video by pressing pause and wait until it has downloaded enough data to watch it smoothly. Hope you got what i mean. thank you

Android - changing/replaying video in videoView

App I'm developing contains many short (1-2 sec) videos.
The videos are displayed in one activity. User can either replay video (possibly while video is beeing played) or change actual video.
Part of code changing video:
String videoPath = getVideoPath();
videoView.setVideoPath(videoPath);
videoView.start();
Those 3 lines already causes app to load new video and play it.
Problem starts after video is completed. From this point loading new video causes many problems (Like sometimes for half a movie only sound is played while screen is black blank). There are similar problems with replaying video (which I end up with calling 3 lanes from above).
It seems like android after completing movie releases resources or something like this (and that's why I am settings same path, when I want to replay video).
Ideally I would want video to simply pause and seekTo to beggining of movie after finished playing (but I cannot do this in OnCompletedListener, since it already changed state to stopped...).
Can I somehow achieve this? (By this I mean -> after completed video pauses and seekTo to beginning)
I already tried all combinations of pausing vidoes, suspending them, setting OnPreparedListener, setting OnCompletedListener.
Thx!

Try something like
mVideoView.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
#Override
public void onPrepared(MediaPlayer arg0) {
mVideoView.start();
}
});
mVideoView.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {
public void onCompletion(MediaPlayer mp) {
mp.reset();
mVideoView.setVideoPath(file.getAbsolutePath());
mVideoView.start();
}
});

stop the playback, change video path, start video
videoView.stopPlayback();
videoView.setVideoPath(newVideoPath);
videoView.start();

I refactored my code in a following way: Everytime I need new video I reload whole activity. It works most of times, but now instead of video blackness at the beginning of playing I sometimes get "Cannot open media file" error.
Has it something to do with android resource managment? I release mediaPlayer in onCompletionListener.
Has anyone had such problem with playing many videos from external storage?

You can do something like this:
videoView.setOnCompletionListener(MediaPlayer.OnCompletionListener { mp ->
mp.seekTo(0);//go to second 0
mp.start()// start again
})
I discover in this link:
https://developer.android.com/reference/android/media/MediaPlayer

Do this.
videoView.setOnPreparedListener { mp ->
mp.isLooping = true
)

Android Media Player - Getting the number of times a video played in SetLooping

I am Playing the video in loop using set Looping(true) option and i will stop the media player after a particular event happened. It is working fine. But i want to know the number of times that my video got played in the loop.

MediaPlayer doesn't provide that information, you need to make it loop yourself and count how many times it has restarted. To do this, something in your app will need to extend OnCompletionListener and do something like
int count = 0;
public void onCompletion(MediaPlayer mediaPlayer) {
count++;
mediaplayer.seekTo(0);
mediaplayer.start();
}
And you need to set mediaPlayer.setLooping(false)
