Re: [Bugreport] v4l-utils/libv4lconvert/ov511-decomp does not shutdown on SIGTERM

Hi, Thanks for the bug report. I must say I don't really like the suggested fix. Can you try removing the kill altogether and moving the 2 close calls to above the waitpid call and see if that helps, I think that is a cleaner solution. Thanks & Regards, Hans On 04/21/2014 03:11 PM, Andrey Volk
