kolibri2zim

kolibr2zim allows you to create a ZIM file from a Kolibri Channel.

It downloads the video (webm or mp4 extension – optionally recompress them in lower-quality, smaller size), the thumbnails, the subtitles and the authors' profile pictures ; then, it create a static HTML files folder of it before creating a ZIM off of it.

[!WARNING] This scraper is under heavy modifications to prepare a v2 including a brand new UI for navigating the tree of content and a move to Vue.JS. These changes are already merged into main branch but not yet completed. Should you be interested in a stable version, please used published versions (PyPI or Docker). We also have a v1 branch for any urgent patch needed to current production version.

Requirements

• Node 20.x
• Python 3.11
• ffmpeg for video transcoding (only used with --use-webm or --low-quality).
• curl and unzip to install Javascript dependencies. See get_web_deps.sh if you want to do it manually.

Installation

Virtualenv

kolibri2zim is a Python3 software. If you are not using the Docker image, you are advised to use it in a virtual environment to avoid installing software dependencies on your system.

python3 -m venv env      # Create virtualenv
source env/bin/Activate  # Activate the virtualenv ('env/Scripts/Activate' in Windows)
pip3 install kolibri2zim # Install dependencies
kolibri2zim --help       # Display kolibri2zim help

Call deactivate to quit the virtual environment.

See pyproject.toml for the list of python dependencies.

cd zimui
yarn install
yarn build
cd ../scraper
hatch run kolibri2zim --name "Biblioteca Elejandria" --output output --zim-file Biblioteca_Elejandria.zim --channel-id "fed29d60e4d84a1e8dcfc781d920b40e" --node-ids 'd92c07655128458f8248416154b18a68,89fe2f86ee3f4fbaa7fb2bf9bd56d088,75f99e6b97d14b14a4e74762ad77391f,89fe2f86ee3f4fbaa7fb2bf9bd56d088'
