offstream

Record your favorite twitch streams automatically and watch them later.

• There is no web UI, just use curl and your favorite video player.
• Streams are recorded as is, without re-transcoding.
• Recordings are never muted.
• Ads are optional.
• You can run it on Heroku (completely free) or locally.
• Recordings are stored on IPFS.
• RSS feed of all recordings is available. It can be consumed by youtube-dl, VLC, and other feed readers.
• Streams are available while recording is in progress.

Installing

Option 1: Heroku

You can deploy the app to Heroku by clicking the button below and following the instructions. IMPORTANT: When the app is deployed, click on the "View" button at the bottom to complete the setup.

Option 2: Local installation

1. Install the package.

   $ pip install offstream
   

2. Setup your local sqlite database located at ~/.offstream/offstream.db.

   $ offstream setup
   

   You will get credentials to control the app. I recommend adding them to your ~/.netrc file (or _netrc on Windows):

   machine <your-app-hostname>
       login offstream
       password <your-password>
   

3. Start the app.

   $ offstream
   

Usage

Once your app is ready, you can add your favorite streamers.

$ curl -n https://your-app-name.herokuapp.com/streamers -d name=garybernhardt
$ curl -n https://your-app-name.herokuapp.com/streamers -d name=esl_sc2 -d max_quality=720p60

The max_quality parameter is optional and defaults to best. Typical stream quality options are
audio_only, 160p, 360p, 480p, 720p, 720p60, 1080p60, best.

When any of the streamers goes live, the app will record the stream.

An RSS feed of all recordings is available at
https://your-app-name.herokuapp.com/rss.

Finally, to watch the latest recording, open the following URL in mpv, VLC, QuickTime, or any other video player.

$ mpv https://your-app-name.herokuapp.com/latest/{streamer_name}

API

• POST /streamers -d name=<streamer_name> -d max_quality=<quality>

  Track a new streamer.

  Requires auth.

• DELETE /streamers/{streamer_name}

  Delete a streamer. WARNING: Deletes all associated recordings too.

  Requires auth.

• GET /latest/{streamer_name}

  Get the latest recorded stream.

• POST /settings -d ping_start_hour=<hour> -d ping_end_hour=<hour>

  Modify ping settings. On Heroku, offstream keeps itself awake 24/7 by pinging itself periodically. You can save some dyno hours by changing the ping_start_hour and ping_end_hour settings to let the app sleep when no one is streaming.

  Requires auth.

• GET /rss or GET /rss?limit=100

  RSS feed of recent recordings.

FAQ

• Q: My video player reports the following error:
  keepalive request failed for 'https://bafybeie3v6lomkfti2b4zsa4yj35nypojllvjrzpbzyxhn5tkfoqaswmbm.ipfs.infura-ipfs.io/18846.ts'

  A: This warning can be safely ignored. It's because Infura keeps the root content identifier (CID) in a subdomain, rather than in the path portion of the URL.
