I run into same kina problem. I'm using THREEAR in an app environment which provides API for getting camera frame data. So I modified the THREEAR API to accept typedarray instead of html element. Sine the given camera data is fixed size in portrait mode, the threejs camera works in wrong aspect ratio. don't know how to fix it.

I got two examples to stress the problem.
fixed size landscape video: https://www.xingway.com/ar2/basic2.html (works fine)
fixed size portrait video: https://www.xingway.com/ar2/basic.html (camera aspect goes wrong)
from threear.
From what I know the camera's aspecto Ratio is always 4/3 regardless of the screen orientation, so maybe you have to change the aspecto after thr source is initialized, depending on the orientation

aspect = prjMatrix[1][1] / prjMatrix[0][0]

hi @0b01001101
thanks for the reply. the examples use basic three camera which dosen't take fov, aspect ratio into acccount.
I tried to use perspective camera and upateProjectionMatrix after the source initializiation. the stretching issue gone, but the 3D Object dosen't attatch the marker correctly anymore.
