need help in setting up panoramic display

[Honbrok]

I have been trying to add a video as a live wallpaper with a panoramic view in an app iam developing. The problem is that it sets in a panoramic view for the first time when i set it as a wallpaper but the second time i attempt to set it it changes to non panoramic. i have been figuring out it for past two days without any success any help or guidance will be appreciated.
