Request: update sample, and add scrolling feature, as well as ability to change which video to play, and use OpenGL3 when possible

[AndroidDeveloperLB]

Seems the video-choosing, scrolling feature, and OpenGL 3 are done here:
https://github.com/AlynxZhou/alynx-live-wallpaper
alynx-live-wallpaper.zip
Or my fork:
https://github.com/AndroidDeveloperLB/alynx-live-wallpaper

But sadly it has no way to change scale-types. Only center-crop, with ability to scroll.

Attached a more updated project of the current repository:
