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

It downloads the video (webm or mp4 extension – optionnaly 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.

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

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
pip3 install kolibri2zim # Install dependencies
kolibri2zim --help       # Display kolibri2zim help

Call deactivate to quit the virtual environment.

See requirements.txt for the list of python dependencies.

docker run -v my_dir:/output ghcr.io/openzim/kolibri2zim kolibri2zim --help

kolibri2zim works off a channel-id that you must provide. This is a 32-characters long ID that you can find in the URL of the channel you want, either from Kolibri Studio or the Kolibri Catalog
