Tmux // Icecast // Liquidsoap // Recording computer playback // RSS feeds
Make a first playlist:
cd /srv/radio ls /var/www/html/*.mp3 >> playlist.m3u
Edit Playlist
nano playlist.m3u
Playlist is here: /srv/radio/playlist.m3u
Bash script for liquisdsoap: playlist.sh
liquidsoap \
'output.icecast(%vorbis,
host = "echo.lurk.org", port = 999,
password = "<pwd>", mount = "radioimplicancies.mp3",
mksafe(playlist("playlist.m3u")))'
The resulting program is here: http://echo.lurk.org:999/radioimplicancies.mp3
Run the playlist, via icecast on Lurk
Start a "tmux session", make it shareable...
tmux -S /tmp/radio new -s radio chgrp publicweb /tmp/radio
For others to be able to watch this terminal
tmux -S /tmp/radio attach -t radio -r
Start the stream
bash playlist.sh
To detach from tmux, leaving liquidsoap [and the stream] running
Ctrl + b d
Listen to the program: http://echo.lurk.org:999/radioimplicancies.mp3
