NullPointerException when trying to play DASH Widevine content

[pM0n]

Trying to play: http://storage.googleapis.com/wvmedia/cenc/tears.mpd

Strange, but in some rare times it plays the video for a short time.

Code:

MediaPlayer mMediaPlayer = new MediaPlayer();
mMediaPlayer.setDataSource(getBaseContext(),Uri.parse("http://storage.googleapis.com/wvmedia/cenc/tears.mpd"));
mMediaPlayer.setDisplay(((SurfaceView) findViewById(R.id.video_surface)).getHolder());
mMediaPlayer.prepare();
mMediaPlayer.play();

Log:
