ARjs: Camera Video not centered / wrong image ratio

This problem arises using aframe v1.2.0 and ARjs master branch

Hey everyone:

Is there a way to center the camera image in ARjs?
I am currently using the version from the master branch, but the video is shifted, when using aframe version 1.2.0.
I know that the newest version of aframe is 1.3.0 but there are known incompatibilities with ARjs master branch. When using the dev branch the errors are resolved, but the video is still not centered.

Image from Android Studio:
Video not centered – Android Studio

The desired video should look like this:
Video centered – Android Studio

Script imports:

src=”https://aframe.io/releases/1.3.0/aframe.min.js”

src=”https://unpkg.com/[email protected]/dist/aframe-look-at-component.min.js”

Kind regards
