Hi MikelDiezGarca ,
You are uysing openvino 2020.1 which is very outdated. So I also assume the depthai version is very outdated, which mean the OAK-D-Lite isn't supported (as it uses different sensors, that are supported since OAK-D-Lite was released). I'd suggest contacting the opencv-ai team directly, maybe opening an issue, as we (Luxonis) are only business partners with them. Thoughts?
