Multicam adapter: previewOpencv.py doesn't work, but AdapterTestDemo.py does

Camera Breakout Boards
1

I am currently running 4 raspberry pi v3 noir camera modules on the Arducam Raspberry Pi Multi-Camera Adapter Module V2.2.

When running previewOpencv.py, All the cameras initialize, then I get an error saying the Dequeue timer of 1206000.00us has expired, and that Unicam has timed out. However, running the AdapterTestDemo.py file runs perfectly well and I am able to initialize every camera and see a preview for each. I’m not sure how to troubleshoot this issue, so any tips would be appreciated.

You can try it first, and we will write a document on the documentation website to explain it later.
