I know this is an old post but this just isn't possible. The ahf file isn't simply a video. It's a capture of the game engine stream as it happened. When you open it with the film viewer it's not playing a video, it's actually re-running the game using that captured stream of data. So, you'd need the entire game to be ported to mobile in order to do this. I'd say that's in snowball's chance territory.
