earhorn

Listen, monitor and archive your streams!

Install

If you need to listen or archive an Icecast stream, you will need ffmpeg:

sudo apt install ffmpeg

Install earhorn from pip (install the s3 extra to upload the segment to an s3 bucket):

pipx install earhorn
pipx install earhorn[s3]

You can start archiving an Icecast stream by providing a stream url and an archive path:

earhorn \
  --stream-url https://stream.example.org/live.ogg \
  --archive-path=/to/my/archive

You can also start exporting the Icecast stats as prometheus metrics by providing an Icecast stats url:

earhorn \
  --stats-url https://stream.example.org/admin/stats.xml \
  --stats-user admin \
  --stats-password hackme

Docker

docker pull ghcr.io/jooola/earhorn

Usage

Usage: earhorn [OPTIONS]

  ENVIRONMENT VARIABLES:

  If a `.env` file is present in the current directory, it will be loaded and can be used to pass environment
  variables to this tool.

  ARCHIVE STORAGE:

  The storage can be defined using a path to a local directory or an url to an s3 bucket. Segments will be saved on
  the storage you specified.

  To use an s3 bucket, you need to install the `s3` extras (`pip install earhorn[s3]`), use `s3://bucket-name` as
  value for the `--archive-path` option and export the s3 bucket credentials listed in the table below:

  | Variable                | Description                               | Example                     |
  | ----------------------- | ----------------------------------------- | --------------------------- |
  | AWS_ACCESS_KEY_ID       | The access key for your bucket user       | AKIA568knmklmk              |
  | AWS_SECRET_ACCESS_KEY   | The secret key for your bucket user       | mi0y84wu498zxsasa           |
  | AWS_S3_ENDPOINT_URL     | The endpoint to your s3 bucket (optional) | https://s3.nl-ams.scw.cloud |
  | AWS_S3_REGION_NAME      | Region of your s3 bucket                  | us-east-2                   |

  Example: export AWS_S3_ENPOINT_URL="https://s3.nl-ams.scw.cloud"

  ARCHIVE SEGMENTS:

  To change the segments duration or format, see the ffmpeg documentation for details
  about the available options:
