How to display a video behind gui on mobile

Is it possibile to play a video, mp4 or other format, behind the GUI in Unity3D for mobile?

Using class MovieTexture it works on desktop, unfortunately MovieTextures aren’t supported on iOS/Android.

And Handheld.PlayFullScreenMovie only plays the movie in full screen.

There is some other method?

(or a solid plugin)

Unfortunately, this is not supported natively. But there is an asset in the store which allows this for mobile platforms. Seems like a common request among mobile developers.
