[Bug 431303] Re: /dev/video
On my fully updated box I have $ ls -l /dev/shm/usb-\:00\:1a.0-2\:USB\ Camera\ \(046d\:08da\) -rw--- 1 root root 4096 2009-11-30 13:36 /dev/shm/usb-:00:1a.0-2:USB Camera (046d:08da) The ubuntu libv4l-0 version is 0.6.0-1 and if it is the same as in Debian, then the 0.6.0-2 version supposedly fixed the problem. I remark that the permission error happens only on my 64 bit box; the same camera works fine on a 32 bit installation of Ubuntu 9.10. -- /dev/video https://bugs.launchpad.net/bugs/431303 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
