Streaming Using Video View works fine but after playing some video Gives Dialog Can Not Play this video

I am using Video View To stream Video.

I am able to start video successfully But what happens is after playing some video I am getting Dialog Box saying Can not play this video.

When I tried multiple times then I realized that It shows me dialog at random length of video played.

I don't able to find why this is happening.
