Plugging a 64 GB USB stick with directories full of MP3 / OGG files into an always-on Raspberry Pi running Pi-Hole, one can use Icecast to stream them for clients on the LAN, so as to avoid over-the-Intertubes streaming issues.
The only changes in the /etc/icecast2/icecast.xml file cover passwords, the number of source streams, and the hostname. It’s that simple, really.
Given a directory of files, generate a file-per-line playlist:
find /mnt/music/goodmusic/ -name \*mp3 | sort > /mnt/music/goodmusic/playlist.m3u
Then set up a corresponding Ezstream XML file, perhaps imaginatively named goodmusic.xml:
<ezstream>
<url>http://localhost:8000/goodmusic</url>
<sourcepassword>make-up-your-own</sourcepassword>
<format>MP3</format>
<filename>/mnt/music/goodmusic/playlist.m3u</filename>
<shuffle>1</shuffle>
<stream_once>0</stream_once>
<svrinfoname>Good Music</svrinfoname>
<svrinfourl>pihole.local</svrinfourl>
<svrinfogenre>Good Music Streaming 24x7</svrinfogenre>
<svrinfodescription>Techno Dub</svrinfodescription>
<svrinfobitrate>128</svrinfobitrate>
<svrinfochannels>2</svrinfochannels>
<svrinfosamplerate>44100</svrinfosamplerate>
<svrinfopublic>1</svrinfopublic>
</ezstream>
Fire off the source stream in /etc/rc.local:
ezstream -c /home/pi/Icecast/goodmusic.xml &
The ampersand tells Bash to fire-and-forget the process, so it runs all the time. One could, I suppose, put it in crontab to start after each boot or puzzle out the corresponding systemd incantation, but …
Add the station to your streaming media player:
'KEY_KP5' : ['Good Music',False,['mplayer','-playlist','http://192.168.1.2:8000/goodmusic.m3u']],
And then It Just Works™.
