Streaming Radio Howto

by Asbesto, 27/2/2018

Liquidsoap streaming for radiocybernet on zaverio.com

We installed liquidsoap:

apt-get install liquidsoap

The program we use is "stream.liq" in ~/radiocybernet:

# Log dir
set("log.file.path","/home/asbesto/radiocybernet/streaming.log")

# local telnet server only, port 1234
set("server.telnet", true)

# Music
myplaylist = playlist("~/radiocybernet/playlist.m3u",reload_mode="watch")

# Some jingles
jingles = playlist("~/radiocybernet/jingles.m3u",reload_mode="watch")

# If something goes wrong, we'll play this
security = single("~/radiocybernet/alfacharlie.mp3")

# Start building the feed with music
radio = myplaylist
# Now add some jingles
radio = random(weights = [1, 4],[jingles, radio])
# And finally the security
radio = fallback(track_sensitive = false, [radio, security])

# Stream it out
output.icecast(%mp3,
  host = "radio.dyne.org", port = 8000,
  password = "bactrim", mount = "rcyb.mp3",
  icy_metadata="true",
  genre = "Live",
  description = "Historical Broadcast live 24/7 - Multilingual - WARNING, can contain STRONG ITALIAN LANGUAGE, MAYBE NSFW ",
  name = "Radio Cybernet - Online since 1997",
  url = "http://www.radiocybernet.org",
  audio_to_stereo(radio))

Main playlist is there, you also have jingles and the security mp3 if something fail. random weights control jingles.

audio_to_stereo reencode weird mp3 formats on the fly so everything work smooth!

Just add a list of MP3 somewhere, create a playlist, and that's all!

TELNET server (local only) is useful but kinda tricky.

TODO

• add automatic live insertion to the playlist above
• ... check random playing (now is random) or sequential playing...

Tricks

Liquidsoap use MP3 id tag as titles etc. - If mp3 doesn't have tags, nothing will be display. So you MUST describe any mp3 in id tags. We used eye3D tool for that - very useful: eye3D -t title mp3.

REALAUDIO FILES to mp3 - must be converted. ffmpeg does this. GOOGLE THAT

Darkice config file

This is the config file for darkice under Linux, to stream on radio.dyne.org, use darkice as darkice -c darkice.cfg where darkice.cfg is the configuration file:

With OSS (OLD :-? Open Sound System)

Control permissions and existance of /dev/dsp dsp1 dsp2, dependently from how many audio cards you have. Tri gom or aumix to control the mixer settings.

Control that there is an audio card with aplay -l and always control that you are part of group audio ( or be root )

Control the mixer with alsamixer ( alsamixer -c1 in case of pulseaudio cadaver )

In alsamixer press the [tab] button on your keyboard to go to the input capture view:

Don't put the capture volume at max or you will get poor quality audio, if your terminal supports colors keep it under the red bar :), in amixergui or thing like that keep the capture volume 2/3 of the max volume.

With the arrows you can cross the input channels, put the capture on the -mix- by pressing the space bar and then set the volumes of the outputs ( again [tab] to switch back to the outputs volumes views) as you wish.

If you plan to use a player like mplayer or audacious or xmms remember to set them to use Master as volume and not PCM otherwise with the music you will take down also mikes line-in cd and what-sallamadonna-not , best to set them on software volume control ( -softvol for mplayer )
