Workaround: If intrinsics-file is from the beginning in the same or relative folder, you can save in this folder and later copy or move the files to another location.
Are you sure you are using the right version? VL.OpenCV has this particular issue in which you need to manually remove older versions when you install a new one.
I would suggest you try and delete all OpenCVSharp and VL.OpenCV versions from your AppData directory and then install the latest.
also, if you save a patch at a new location, the patch of the new location is already opened… so could you tell us in even more detail what you do or record a screen capture?
I have tried to open the patch after closing vvvv and also after closing only the patch and it crashes anyway
It apparently saves the patch to new location and it keeps working (doesn’t seems to reload the patch)
It´s only when you close the patch or vvvv and try to reopen the patch when it crashes
…sometihng like this…
confirmed. the previously mentioned fix was only fixing the problem with the EstimatePose node. but in this particular patch the Undistort node has a similar problem. thanks for the pointer.
