onStateFling is not called

[perusudroid]

While scrolling the next neighbour item is loaded. But i can't able to pause the video playing in the current view. While playing video if i scrolled next video is also playing. deactivateCurrentItem is not triggering onStateFling.

While scrolling, neighbour video is played but i want to release the video from current view and make the Thumbnail imageview visible.

Please help me to solve this....
