These are file management tools for videos recorded by my bicycle helmet camera.
Plug your camera into your computer and run lsusb to retrieve information
about connected USB devices. Locate your camera in the device list and note the
USB vendor and product ID for your device. For example, lsusb prints the
following for my camera (an original ContourROAM):
Bus 003 Device 045: ID 0d64:5566 DXG Technology Corp.
In this example, 0d64 and 5566 are the USB vendor and product ID,
respectively.
To automatically copy video files from your camera to your hard drive when your
camera is plugged in via USB, run setup-udev to install a udev rule for your
device. Specify your camera's USB vendor and product ID, as well as a
destination directory to copy videos to:
./setup-udev -d path/to/videos/directory -v 0d64 -p 5566The udev rule will be placed in /etc/udev/rules.d/81-helmet-camera.rules.
setup-udev will automatically reload the udev rules. Unplug and replug your
camera to test video import.
setup-udev accepts additional arguments that can be passed along to
import-videos via the installed udev rule. Run setup-udev --help for more
information.
Provide an email address to setup-udev using -e/--email-address to receive
an email notification when video import is complete. This feature requires your
system to have a working sendmail in /usr/sbin/sendmail.
import-videos is meant to run automatically via udev. It mounts the camera
device, copies video files to a directory specified by the user, and unmounts
the camera.
I wrote this script to handle my specific camera (an original ContourROAM), but it may be useful for video import from any camera that presents videos to the host via USB mass storage.
An appropriate udev rule can be automatically installed using setup-udev. See
the "Quick setup" section above for more information. These instructions
describe how to configure udev manually.
To configure import-videos to run automatically, create a udev rule such as
the following (the entire rule must be placed on a single line):
KERNEL=="sd?1", ATTRS{idVendor}=="0d64", ATTRS{idProduct}=="5566", ACTION=="add", MODE="664", RUN+="/path/to/helmet-camera/import-videos -e 'email@example.com' -d '/path/to/videos/directory'"
Note that the import-videos executable name and the target videos directory
argument must be absolute paths.
The email argument is optional, but recommended. If specified, a summary is emailed from and to the specified address when video import is complete. This feature requires a working sendmail in /usr/sbin/sendmail.
If you have a camera other than the original ContourROAM, you will likely want
to change the idVendor and idProduct values in the above example rule. You
can determine the correct values for your hardware by examining the output of
lsusb.
Place your udev rule in /etc/udev/rules.d, for example in a file named
/etc/udev/rules.d/81-helmet-camera.rules.
After creating your udev rule, you may need to reload your udev configuration by running:
$ sudo udevadm control --reloadPlease note this udev rule has been tested on Gentoo Linux. I am not sure if these instructions are portable to other Linux distributions.
This is a utility meant to be run manually for organizing already-imported
video files. import-videos places all video files directly into the
specified destination directory. organize-videos can be used to organize
video files into subdirectories based on the recording count.
organize-videos uses a hardcoded organization method based on how the
ContourROAM names its video files. Please see the top of
video_utils/__init__.py for an explanation.
Video file organization can also happen automatically in import-videos with
the -o/--organize option.
This utility removes video files to free disk space, in order by video number
from lowest to highest. cleanup-videos removes videos until the amount of
disk space specified by -f/--free-space (in GiB) is available.
Video file organization can also happen automatically in import-videos by
specifying the desired amount of free disk space (in GiB) with the
-c/--clean-up-free-space option.
