Java crash when video capture is released about opencv HOT 5 CLOSED

Hi @mdagraca,

The OpenCV version is the one named in the jar version. So, 3.2.0-1 is OpenCV 3.2.0, jar version 1. Jar version 2 would be 3.2.0-2, and so on.

I do not run into this issue with my code, although I am using 2.4.11-2 in my project. Could you try with that version and see if you get the same thing?

For reference, the code I use is basically identical to yours: https://github.com/openpnp/openpnp/blob/develop/src/main/java/org/openpnp/machine/reference/camera/OpenCvCamera.java#L204

I have fallen behind on updating versions of this library. I'll put it on my schedule to get a new version pushed soon.

Thanks,
Jason

Thanks Jason.
I think there is something wrong with the threads. I'm testing it.
The videoCapture is opened when the user clicks on the start button (JavaFX) and released when the user clicks on the stop button.

I'm still having this error when the video capture object is released.

I've just released version 3.4.2-0, please try this and see if it resolves the issue.
