My ipad reboots while watching videos on youtube

So I was watching videos on YouTube last night..and everything seems to be fine for me.I can play all the videos in just fine.

But when I played a certain video,means only one video does it,it actually reboots my iPad.On it's middle or 1/4part.It's like a tv that has lost it's channel..like a colorful thingy then it restarts my ipad afterwards.Is it my ipad's problem? As for me,i haven't droped it in its entire life,just a little bump on the wall..a light bump.

What do you think is the problem?
