description     "Replay go2001 video codec device udev events"
author          "chromium-os-dev@chromium.org"

# This job is used to replay events of the go2001 video codec device. Chrome
# queries the video nodes for hardware decode and encode capabilities when it
# starts. The video nodes have to be present before it starts. So this job is
# a task and blocks Chrome to start.
#
# To avoid hardcoding the names in udev-trigger.conf, these events are
# replayed again there. But these events are simple and do not increase
# much boot time.
