Hi,the current ubuntu guvcview version is broken with kernels >= 3.16, you need the latest version 2.0.1 You can get it from the sourceforge download (Files) section or from one of my ppa's:
stable: https://launchpad.net/~pj-assis/+archive/ubuntu/ppa testing (latest git): https://launchpad.net/~pj-assis/+archive/ubuntu/testing Regards, Paulo
