Issue is present on both Unity 2018.3.6f1 & Unity 2018.3.11f1 (latest) however I can only seem to reproduce this on my laptop, as everything works fine on my PC.
I have tried both internal and external webcams but the issue is still the same. The steps I took were switching platform to android, removing the Main Camera, adding in the WikitudeCamera, changing he webcam to my external webcam and finally playing live preview.
Thank you for reporting this issue. Can you please confirm that the same webcam is working correctly on your PC, but not on your laptop? We've seen similar reports from other customers, but we're having trouble reproducing this issue internally, so every bit of information help.
Additionally, can you try changing the resolution of the Game panel, from "Free Aspect" to something else? Does matching the resolution of the camera, for example, help with the issue?
This video should confirm that the webcam functions on my PC but not my laptop, and that changing the resolution from Free Aspect to the webcam's resolution doesn't fix the issue.
If you have managed to solve the issue for the other customers, then I would really appreciate it if you could share the fix.
I'am currently having the same issue even if my webcam works good. (I did some test with my webcam in unity whithout wikitudecamera)
If there is any solution, give me the info please.
Unity version : 2019.2.0b3
The issue is caused by display scaling options in Windows. This will be fixed in the next update, but until then, please make sure that scaling is set to 100%.
