automated-youtube-dl

Automated YouTube Archival.

A wrapper for youtube-dl used for keeping very large amounts of data from YouTube in sync. It's designed to be simple and easy to use.

I have a single, very large playlist that I add any videos I like to. On my NAS is a service uses this program to download new videos (see [Example systemd Service.md]).

Features

• Uses yt-dlp instead of youtube-dl.
• Skip videos that are already downloaded which makes checking a playlist for new videos quick because youtube-dl doesn't have to fetch the entire playlist.
• Automatically update yt-dlp on launch.
• Download the videos in a format suitable for archiving:
  • Complex format that balances video quality and file size.
  • Embedding of metadata: chapters, thumbnail, english subtitles (automatic too), and YouTube metadata.
• Log progress to a file.
• Simple display using tqdm.
• Limit the size of the downloaded videos.
• Parallel downloads.
• Daemon mode for running as a system service.

Installation

sudo apt update && sudo apt install ffmpeg atomicparsley
pip install -r requirements.txt

Usage

./downloader.py <URL to download or path of a file containing the URLs of the videos to download> <output directory>

To run as a daemon, do:

/usr/bin/python3 /home/user/automated-youtube-dl/downloader.py --daemon --sleep 60 <url> <ouput folder>

--sleep is how many minutes to sleep after completing all downloads.

Folder Structure

download-archive.log contains the videos that have already been downloaded. You can import videos you've already downloaded by adding their ID to this file.

Videos will be saved using this name format:

[%(id)s] [%(title)s] [%(uploader)s] [%(uploader_id)s]
