icecast

Icecast can be a bit tricky to setup for testing purposes.

    $ doas pkg_add icecast
    ...

Maybe not the package addition part, but rather the configuration. In this case I was testing whether client software to stream to anonradio on SDF would work with a local icecast server, so I needed something that acts at least superficially like the SDF anonradio. Hence the "openmic" and "anonradio" stuff in the following configuration file. Probably you will want to change the passwords?

=> icecast.xml

The configuration file probably needs more work.

    $ ls -l /var/icecast/icecast.xml
    -rw-------  1 _icecast  _icecast  1882 Sep 26 12:01 /var/icecast/icecast.xml
    $ doas icecast -c /var/icecast/icecast.xml
    ...

Ezstream

ezstream is what I picked to stream files to the server.

    $ doas pkg_add ezstream madplay lame
    ...

It is slightly buggy on OpenBSD 7.3 in that streaming MP3 files fails.

    ezstream[5310]: stream: default: format: MP3: This libshout doesn't support the requested option

One can patch and compile a local version of ezstream and to put that binary somewhere in your PATH. Hopefully this patch (from 2021, this document written 2023) or maybe a better fix gets applied to upstream and then eventually makes its way to the OpenBSD ports system?

=> stream.patch

ezstream needs a configuration file, which is also XML. This assumes a localhost server running on a particular port, and that a playlist.m3u file has been created, which should have some paths to some MP3 files, one per line.

=> localhost.xml

    $ ezstream -c localhost.xml
    ...

Listen

A bunch of different audio programs can listen to streams, e.g. mpv, mpg123, and others.

    $ mpv http://localhost:8010/openmic
    ...

=> https://anonradio.net/
