Spoiler Tag How to edit when I close and lock the video content

[WDS]

I do not know if and explained well, but here goes.

I'm looking for some spoiler or tell me I should change so that when you close a spoiler that contains a video or an MP3 player such that it stops, ie stops working.

I leave here an example of what I want:

search: VALUS, MINOTAURUS COLOSSUS (1 st spoiler down)

As you will see if you get to play video and then close the spoiler this video will stop.

Thanks
