When i try camera with ffplay,it works, but not with jevois inventor

Question

Hello, i am on Ubuntu 18, and i bought 2 cameras Jevois. After flashing the micro sd card, i tried jevois inventor on both cameras and got only pure blackscreen. But when i try ffplay, the video set up perfectly on screen. So the problem seems not to come from cameras... Any ideas?

Answer 1

Maybe some graphics driver issue? jevois inventor is using Qt which will use OpenGL if available, so maybe there are issues with your OpenGL or graphics drivers.
