Auto ripper

S & C is a group specializing in the production of front actuators for construction equipment and has been a successful strategic partner with Doosan Infracore since 1999. It collaborated with a well-known Japanese construction machine manufacture as a partner four years ago.

Among the current flagship products are its auto ripper and vibro hammer. The former reduces noise by more than 10dB against hydraulic breakers and secures performance two to five times higher covering 70% of all different types of working sites compared to hydraulic breakers. Most field works such as breaking, ripping and crushed rubble handling can be handled simultaneously. It can carry out construction work even in city zones as places sensitive to machine noise. It minimizes operators’ vibration fatigue compared to other ripper machines, so the operators’ preference for this fatigue relief can contribute to high job efficiency. Construction work in rivers and oceans is possible without extra optional devices. Thanks to its design, it ensures lower maintenance cost than the existing hydraulic breakers. With additional option devices, the ripper can be used as a compactor or pile-driving hammer.

The latter is attractive equipment. It also gives a benefit of lower cost of maintenance than a crane hammer. With outstanding workability and mobility, it ensures easier operation in critical regions such as chaotic sections of a city, bridge areas and the vicinity of high-voltage lines than a crane hammer does. It is equipped with a high-powered hydraulic motor and suitable bearing for high frequency vibration. For high-frequency purposes, vibro isolating rubber is installed.

Automatic Ripping Machine (ARM)

Upgrading from v2_master to v2.2_dev

If you wish to upgrade from v2_master to v2.2_dev instead of a clean install, these directions should get you there.

Backup config file and replace it with the updated config

There are new config parameters so review the new arm.yaml file

Make sure the ‘arm’ user has write permissions to the db directory (see your arm.yaml file for locaton). is writeable by the arm user. A db will be created when you first run ARM.

Make sure that your rules file is properly copied instead of linked:

Otherwise you may not get the auto-launching of ARM when a disc is inserted behavior on Ubuntu 20.04.

Please log any issues you find. Don’t forget to run in DEBUG mode if you need to submit an issue (and log files). Also, please note that you are running 2.2_dev in your issue.

Insert an optical disc (Blu-Ray, DVD, CD) and checks to see if it’s audio, video (Movie or TV), or data, then rips it.

  • Detects insertion of disc using udev
  • Auto downloads keys_hashed.txt and KEYDB.cfg using robobrowser and tinydownloader
  • Determines disc type.
    • If video (Blu-Ray or DVD)
      • Retrieve title from disc or Windows Media MetaServices API to name the folder “movie title (year)” so that Plex or Emby can pick it up
      • Determine if video is Movie or TV using OMDb API
      • Rip using MakeMKV or HandBrake (can rip all features or main feature)
      • Eject disc and queue up Handbrake transcoding when done
      • Transcoding jobs are asynchronusly batched from ripping
      • Send notification when done via IFTTT or Pushbullet
    • If audio (CD) – rip using abcde
    • If data (Blu-Ray, DVD, or CD) – make an ISO backup
  • Headless, designed to be run from a server
  • Can rip from multiple-optical drives in parallel
  • HTML UI to interact with ripping jobs, view logs, etc
  • Ubuntu Server 18.04 (should work with other Linux distros) – Needs Multiverse and Universe repositories
  • One or more optical drives to rip Blu-Rays, DVDs, and CDs
  • Lots of drive space (I suggest using a NAS like FreeNAS) to store your movies

Pre-Install (only if necessary)

If you have a new DVD drive that you haven’t used before, some require setting the region before they can play anything. Be aware most DVD players only let you change the region a handful (4 or 5?) of times then lockout any further changes. If your region is already set or you have a region free DVD drive you can skip this step.

Setup ‘arm’ user and ubuntu basics:

Sets up graphics drivers, does Ubuntu update & Upgrade, gets Ubuntu to auto set up driver, and finally installs and setups up avahi-daemon

Set up repos and install dependencies

Install and setup ARM

Set up drives

Create mount point for each dvd drive. If you don’t know the device name try running dmesg | grep -i -E ‘\b(dvd|cd)\b’ . The mountpoint needs to be /mnt/dev/. So if your device name is sr0 , set the mountpoint with this command:

Repeat this for each device you plan on using with ARM.

Create entries in /etc/fstab to allow non-root to mount dvd-roms Example (create for each optical drive you plan on using for ARM):

Configure ARM

Edit your “config” file (located at /opt/arm/arm.yaml) to determine what options you’d like to use. Pay special attention to the ‘directory setup’ section and make sure the ‘arm’ user has write access to wherever you define these directories.

Edit the music config file (located at /home/arm/.abcde.conf)

To rip Blu-Rays after the MakeMKV trial is up you will need to purchase a license key or while MakeMKV is in BETA you can get a free key (which you will need to update from time to time) here: https://www.makemkv.com/forum2/viewtopic.php?f=5&t=1053 and create /home/arm/.MakeMKV/settings.conf with the contents:

For ARM to identify movie/tv titles register for an API key at OMDb API: http://www.omdbapi.com/apikey.aspx and set the OMDB_API_KEY parameter in the config file.

After setup is complete reboot.

Optionally if you want something more stable than master you can download the latest release from the releases page.

Email notifcations

A lot of random problems are found in the sysmail, email alerting is a most effective method for debugging and monitoring.

Then configure /etc/aliases e.g.:

Run below to pick up the aliases

  • Insert disc
  • Wait for disc to eject
  • Repeat

When a disc is inserted, udev rules should launch a script (scripts/arm_wrapper.sh) that will launch ARM. Here are some basic troubleshooting steps:

Look for empty.log.

  • Everytime you eject the cdrom, an entry should be entered in empty.log like:
  • Empty.log should be in your logs directory as defined in your arm.yaml file. If there is no empty.log file, or entries are not being entered when you eject the cdrom drive, then udev is not launching ARM correctly. Check the instructions and make sure the symlink to 51-automedia.rules is set up right. I’ve you’ve changed the link or the file contents you need to reload your udev rules with:

Check ARM log files

  • The default location is /home/arm/logs/ (unless this is changed in your arm.yaml file) and is named after the dvd. These are very verbose. You can filter them a little by piping the log through grep. Something like

This will filter out the MakeMKV and HandBrake entries and only output the ARM log entries.

  • You can change the verbosity in the arm.yaml file. DEBUG will give you more information about what ARM is trying to do. Note: please run a rip in DEBUG mode if you want to post to an issue for assistance.
  • Ideally, if you are going to post a log for help, please delete the log file, and re-run the disc in DEBUG mode. This ensures we get the most information possible and don’t have to parse the file for multiple rips.

If you need any help feel free to open an issue. Please see the above note about posting a log.

Pull requests are welcome. Please see the Contributing Guide

If you set ARM up in a different environment (harware/OS/virtual/etc), please consider submitting a howto to the wiki.
