Simple twitch client displaying and archiving a playlist for a livestream.


  twitch.rb stream CHANNEL           # output an m3u8 suitable for most media players
  twitch.rb archive CHANNEL [LIMIT]  # archive the most recent streams
  twitch.rb gc [LIMIT]               # Show commands and statistics to limit the archive


  • Clone the repository
  • gem install concurrent-ruby thor pry twitch-api m3u8
  • ./twitch.rb help


During a livestream, Twitch automatically populates it's archive with an update frequency of roughly 5 minutes. The archiver will catch up to Twitch's archive on each run. Running the archiver periodically ensures gapless transitions between restarts of streams. A certain kind fellow has written a front-end.


The current format consists of two parts, top-level vods.json and a video.json with the properties for each video as Twitch serves it.

  "streamer_name": [
      "meta": "relative/path/to/video.json",
      "video": "relative/path/to/",
      "playable": true,
      "source": "relative/path/to/index.m3u8",
      "twitch": {.. contents of meta ..},
//  ...

The playable property indicates whether the video chunks have been deleted to conserve space. If false then source will be omitted. Make use of the url property from the object referenced by meta to provide a link to Twitch.

Known Issues

The archiver writes the meta files before each part of the playlist is downloaded and when nothing is downloaded at all. This has two effects:

  • For a short duration the meta files thus reference non-existing objects. This is not a problem in regular operations as the time to catch up is usually less than the length of even a single chunk. This means it is essentially invisible to clients. Were this to use promises over manually managing a tasks in a threadpool.
  • Modification times are nolonger indicative. There is however a suitable time in the meta file video.json. The lack of mtime (or ctime) makes deletions a bit of a nuisance. As find archive -mtime +20 -delete is unsuitable limiting storage space should probably be integrated in the archive command.
