Support multiple LIBRARY_ROOT directories

[MarcSeebold]

Feature description

I have two drives I'd like to use as my library:

• /ssd/media
• /ssd4tb/media

I tried creating a new folder with two softlinks, but it seems that Kyoo doesn't follow softlinks.

Two possible solutions:

1. Add support for multiple library roots
2. Follow softlinks

Library are mounted as docker volumes, symlinks across volumes mostly don't work in docker.
You can effectively use multiples directory by manually editing the docker-compose.yml file. You'll need to change

  volumes:
    - ${LIBRARY_ROOT}:/video:ro

by

  volumes:
    - /ssd/media}/video/ssd:ro
    - /ssd4tb/media}/video/ssd4tb:ro

If you do change that, you'll need this edit in two places: in the x-transcoder's volume definition and in the scanner's volume definition.

If this is something that people often needs, we might want to look into easier ways of doing that ; for example using reusable volumes scopes for the transcoder/scanner.

(i'm closing this, but feel free to comment if you need more help!)
