I'm trying vuforia in a Tablet Android PIPO Max-M1, and the video appears mirrored, and don't detect the marker.
If I flip the marker in the photoshop, it detects the marker and appear the 3d.
I tried to flip the image with the "Mirror Video Background" Option, and the video appear well, but it still detect the marker in mirrored version. It seems that this option is only for visualization, not for the detection module.
Some others clients contact me with this same behaviour, exactly with a tablet teraware k707g.
It seems, that this "artifact" appears in some chinese tablet models, and is possible that it will be extensible to others tablets thanks to the low prize of this tablets.
Can you help me?
