SIGSEGV while write video with x264 encoder

edit

Hey

I'm using the OpenCV VideoWriter to create some video's. The good news that it works, but unfortunately isn't very stable. The system crashes randomly with a segmentation fault.

I've debugged with GDB and located the issue with libx264. I was wondering if I could do something about it? Is it caused by writing a wrongly formatted image? I have this issue with IP camera's and USB camera's.

Program received signal SIGSEGV, Segmentation fault.
