Clearly format : RGB32_-1442840129x1515803904 is invalid
It must be like RGB32_720x480. But 1442840129x1515803904 is huge Resolution and beyond ROIPosition limits. Contact matlab support team for invalid supported formats.

Moreover... There can be problem with frame grabber communication because of:
1) Frame grabber is not for windows (winvideo)
2) The driver of frme graber is not for (specific) windows
3) Error in driver code
