[Bug 1353139] Re: [manta] video playback currently broken (denied by apparmor)

  Thread Previous • Date Previous • • Thread Next 
mediascanner2 needs to add this to its apparmor policy:
  /sys/devices/**/video4linux/video** r,

media-hub needs to add this to its policy:
  /sys/devices/**/video4linux/video** r,

The media-hub orcexec issue is already fixed, but you may not have the policy update loaded due to bug #1350673. This will be fixed in the next apparmor upload (scheduled for next week). To workaround the orcexec issue, please do:
$ sudo rm -f /etc/apparmor.d/cache/*
$ sudo reboot
