Hi @eduramiba,
I just tested the project and have some issues on Windows 10, not MacOS. Same on a colleage laptop.
I ran TestDriver.java from the project. It does not display anything.
What I notice is it works with a resolution of 160x120, 320x180, 320x240 but not beyond.
Here are the logs when I switched to 160*120, then the ones in 640 * 480

What should I check to have more information? Have you ever notice this problem?
Here is the code used to add a resolution choice box.
Also notice that camera.close() is not enough to close the camera. It must be followed by dispose().
