Save the video position and resume later

You can save the current playback position in a video and resume playing at the same position in a future session.

Dynamically inserted ads differ between user sessions, so saving the position with spliced ads refers to a different position in a future session. TVSDK provides methods to retrieve the playback position while ignoring spliced ads.

  1. When the user quits a video, your application retrieves and saves the position in the video.


    Ad durations are not included.

    Ad breaks can vary in each session due to ad patterns, frequency capping, and so on. The current time of the video in one session might be different in a future session. When saving a position in the video, the application retrieves the local time, which you can save on the device or in a database on the server.

    For example, if the user is at the 20th minute of the video, and this position includes five minutes of ads, getCurrentTime will return 1200 seconds, while getLocalTime at this position will return 900 seconds.


    Local time and current time are the same for live/linear streams. In this case, convertToLocalTime has no effect. For VOD, local time remains unchanged while ads play.

    // Save the user session when player activity stops
        public void onStop(){
            prefs = PreferenceManager.getDefaultSharedPreferences(
            SharedPreferences.Editor editor = prefs.edit();
            // get the local time where stream stopped playing and
            // save it in System preferences
            editor.putLong(LAST_LOCAL_TIME, _mediaPlayer.getLocalTime());
            editor.putString(LAST_MEDIA_RESOURCE, _contentInfo.toMediaResource().getUrl());
  2. Restore the user session when player activity resumes.

    public void onResume() {
        prefs =
        if (prefs.getString(LAST_MEDIA_RESOURCE, "nil").
          equals(_contentInfo.toMediaResource().getUrl())) {
            _lastKnownLocalTime =
              prefs.getLong(LAST_LOCAL_TIME, 0); // get the last local time
                                                 // saved in system preferences
            if(_lastKnownLocalTime > 0) {
                _shouldResumePlayback = true;
  3. To resume the video at the same position:

    • To resume playing the video from the position that was saved from a previous session, use seekToLocalTime.


      This method is called only with local time values. If the method is called with current time results, incorrect behavior occurs.

    • To seek to the current time, use seek.

  4. When your application receives the onStatusChanged status change event, seek to the saved local time.

    private final MediaPlayer.PlaybackEventListener _playbackEventListener =
      new MediaPlayer.PlaybackEventListener() {
        public void onPrepared() {
                if(_lastKnownLocalTime >= 0) {
  5. Provide the ad breaks as specified in the ad policy interface.

  6. Implement a custom ad policy selector by extending the default ad policy selector.

  7. Provide the ad breaks that must be presented to the user by implementing selectAdBreaksToPlay.

    This method includes a pre-roll ad break and the mid-roll ad breaks before the local time position. Your application can decide to play a pre-roll ad break and resume to the specified local time, play a mid-roll ad break and resume to the specified local time, or play no ad breaks.
