Superliminal

Small http app for Subliminal subtitle downloader to use with Sonarr / Radarr webhooks.

Why?

When you don't want to touch/alter the official Docker images of Sonarr / Radarr it's impossible to neatly integrate Subliminal next to those as another container. (At least without dirty container privilege haxx) This is simply a small webservice on top of the official Subliminal container which listens for Sonarr / Radarr webhook requests and then runs Subliminal on the downloaded file accordingly.

Some limitions

• This will not pro-actively search for subtitles afterwards. It's a simple fix to use Subliminal in a Docker container too and never intended to be more.
• For best results movie/series files should not be renamed.

Installation

• Setup this Docker container next to your other Sonarr / Radarr container(s).
• Make sure you map the /config volume to something you can access. Also map your video folders EXACTLY the same way you have in your Sonarr / Radarr containers. (Ex: /videos /tv /anime should be accessible using the same volume paths!)
• Run the superliminal container and edit arguments.txt (found in /config) accordingly.
• Add the webhook in Sonarr / Radarr

Example of arguments.txt

{
    "default": "--cache-dir /config --addic7ed YOURUSERNAME YOURPASSWORD --opensubtitles YOURUSERNAME YOURPASSWORD download -p addic7ed -p opensubtitles -l nl -m 85 -v \"#FILE#\"",
    "sonarr": null,
    "radarr": null
}

Then #FILE# will be replaced with the complete filepath of a tv show of movie after downloading. If you want different Subliminal parameters for Sonarr or Radarr use the corresponding values accordingly. The default parameters will be used when sonarr / radarr is null.

Add a webhook in Radarr/Sonarr

Go in Settings to configure a "Connect" WebHook:

• Settings > Connect > add WebHook notification
• Select On Download and On Upgrade
• URL: http://<ip address>:<port>/
• Example: http://192.168.2.2:8978/
• Method: POST

This was intended for personal use and it 'works-for-me ™' so just shoot a pull request / issue if you see room for improvement. Tested on a Synology DS216+II with 8GB RAM.

Troubleshooting

Check the logs in /config for any pointers on what is wrong. :D
