Since Coub started blocking coubs, I've slapped together a tool to save coubs locally in highest quality.
- Ruby (tested using
ruby 2.7.4p191 (2021-07-07 revision a21a3b7d23) [x86_64-linux-gnu]) - Nokogiri
- FFmpeg (tested using
ffmpeg version 4.3.4-0+deb11u1 Copyright (c) 2000-2021 the FFmpeg developers)
./download.rb -u URL
Provided a valid coub URL will create a directory with coub permalink in current directory, download coub metadata, video, audio and join them using FFmpeg.
cat links.txt | while read url; do
./download.rb -d ~/Downloads/coubs -u "$url"
sleep 0.5
done
Given coub links (one per line) in links.txt, will attempt to download all of them to ~/Downloads/coubs/$permalink.
Unless script gets a valid JSON from a page, it will not do anything.
Everything is cached: JSON is saved as $permalink/coub.json, audio as $permalink/audio.ext, video as $permalink/video.ext and will not be downloaded again if sizes match what's in JSON.
The script will throw an error if output file ($permalink/coub.mp4) already exists. In this case, simply nuke the output file or whole directory and try again.
