Youtube2zim

CodeFactor Docker Build Status License: GPL v3 PyPI version shields.io

youtube2zim allows you to create a ZIM file from a Youtube Channel/Username or one-or-more Playlists.

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.

Requirements

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

Installation

Here comes a few different ways to install youtube2zim.

Virtualenv

youtube2zim is a Python3 software. If you are not using the Docker image, you are advised to use it in a virtualenv to avoid installing software dependences on your system.

virtualenv -p python3 ./ # Create virtualenv
source bin/activate      # Activate the virtualenv
pip3 install youtube2zim # Install dependencies
youtube2zim --help       # Display youtube2zim help

At the end, call deactivate to quit the virtual environment.

See requirements.txt for the list of python dependencies.

Docker

docker run -v my_dir:/output openzim/youtube youtube2zim --help

Globally (on GNU/Linux)

sudo pip3 install -U youtube2zim

Usage

youtube2zim uses Youtube API v3 to fetch data from Youtube. You thus need to provide an API_KEY to use the scraper.

To get an API:

  1. Connect to Google Developers Console
  2. Create a new Project then Select it.
  3. When asked, choose Create Credentials and select the API Key type. (Credentials page)
youtube2zim --api-key "<your-api-key>" --type user --id "Vsauce"

Notes

  • Your API_KEY is subject to usage quotas (10,000 requests/day) so use --only_test_branding when adjusting parameters and branding to not waste your quota.
  • If you encounter issues reading ZIM files created using this scraper, please take a look at the Compatibility Matrix before opening a ticket.

youtube2zim-playlists

youtube2zim produces a single ZIM file for a youtube request (channel, user, playlists.

youtube2zim-playlists allows you to create one ZIM file per playlist instead.

This script is a wrapper around youtube2zim and is bundled with the main package.

Usage

youtube2zim-playlists --help

Sample usage:

youtube2zim-playlists --indiv-playlists --api-key XXX --type user --id Vsauce --playlists-name="vsauce_en_playlist-{playlist_id}"

Those are the required arguments for youtube2zim-playlists but you can also pass any regular youtube2zim argument. Those will be forwarded to youtube2zim (which will be run independently for each playlist).

Specificities:

  • --title and --description are mutually exclusive with --playlists-title and --playlists-description.
  • If using --title or --description, all your playlists ZIMs will have the same, static metadata. This is rarely wanted.
  • --playlists-title and --playlists-description allows you to dynamically customize them via some playlist-related variables:
    • {title}: the playlist title
    • {description}: the playlist description
    • {slug}: slugified version of the playlist title
    • {playlist_id}: playlist ID on youtube
    • {creator_id}: playlist's owner channel/user ID.
    • {creator_name}: playlist's owner channel/user name.
  • You can omit them and youtube2zim will auto-generate those.
  • you must specify --playlists-name (supports variables listed above).
  • --playlists-name is used to set the Name metadata of the ZIM (should be unique) and if not set separately, the output file name for the ZIM.
  • --metadata-from allows to specify a path or URL to a JSON file specifying custom static metadata for individual playlists. Format:
{
    "<playlist-id>": {
        "name": "",
        "zim-file": "",
        "title": "",
        "description": "",
        "tags": "",
        "creator": "",
        "profile": "",
        "banner": ""
    }
}

All fields are optional and taken from command-line/default if not found. <playlist-id> represents the Youtube Playlist ID.

If you feel the need for setting additional details in this file, chances are you should run youtube2zim independently for that playlist (still possible!)
