Hi and thanks for the reply.
I don’t think it’s a permission issue, since every other ccv settings are saved without any problem, including the setting of the first camera (i.e. camera position in source setting as well as the calibration points array).
The problem is the setting of the second camera, which is saved correctly (in the multipliex.xml) but not recognized on ccv restart. It looks like ccv cannot pair the setting previously saved to the camera connected.
I did other test without luck, i.e. exchange the Ps3 eye (I have four ps3 for testing), exchange usb ports.
Hope and thanks for any advices that can solve the issue.
@todo.to.it - few community members got this problem. And they solved it by granting write permission inside CCV folder.
