If for any reason the my program crashes, I cannot run it again without getting the following error:
VIDIOC_STREAMON: Invalid argument
in an endless loop. I have tried to unload some kernel modules (such as ucvideo) and reloading them again but it didn't help. The only solution is to restart the whole system. This is however not feasible. I would appreciate any comments.
I use OpenCV 2.4.8 on Ubuntu 13.10.
