Stereo to mono sound error or Gov hack?

[dessipation]

I have noticed that I get the audio feed when listening to my stereo headphones and when I am watching a youtube video or watching a video that I downloaded on my iPad, I would get my right side audio cut off, with or without wifi/bluetooth connection. I assume the mono speakers on the iPad itself is left channel or both at the same time? What is funny about this sudden stereo to mono transition is that after some duration, it switches back to stereo.
can anyone explain why this is happening?

Well, after watching the same videos, it turns out that some guy formatted the video so that it would be in mono an then stereo... sorry about the unverified observation.
