[SOLVED] How to configure external Icecast2 server - Airtime Support Discussions on Sourcefabric Forum

Rodolfo Pilas · Post edited by Rodolfo Pilas at 2011-11-08 17:14:08

I have just installed Airtime 1.9.4 at Ubuntu Studio 10.04 (lucid) with .deb packages.

I lived Icecast2 uninstalled and unconfigured to use my EXTERNAL server, but I have not success to configure it.

In particular I have the exact problem like this post. I configured /etc/airtime/liquidsoap.cfg but it do not works.

I check it with command line:

$ /usr/lib/airtime/pypo/bin/liquidsoap_bin/liquidsoap 'output.icecast(%mp3, mount="test.ogg", host="164.73.XX.XX", port=8888, password="Pass", sine())'

Can you please tell me how I configure a external Icecast2 server?

(I have seen documentation and wiki and forum, but perhaps I have not seen the right document)

Martin Konecny

Make that line

/usr/lib/airtime/pypo/bin/liquidsoap_bin/liquidsoap 'output.icecast(%vorbis, host = "localhost", port = 8000, password = "hackme", mount = "liq.ogg", mksafe(single("/path/to/mp3")))'

Rodolfo Pilas

SOLVED!!

The radios is ON AIR now, and streaming thought a remote icecast server.

Thank you very much Martin and Paul.

I will add Uniradio http://www.uniradio.edu.uy, the first University Radio of Uruguay, (South America), as soon it become online with Airtime.

That should be all you need to do...can you send the liquidsoap.cfg file to
us and the results of airtime-check-system?

As you may see at the first post, the server has proper connection to broadcasting Icecast server.

Thank you for your help.

Hi,

Please try the following from the command line

liquidsoap 'output.icecast(%vorbis, host = "localhost", port = 8000, password = "hackme", mount = "liq.ogg", mksafe(single("/path/to/mp3")))'

with your custom parameters set up. Does it work then?

Rodolfo Pilas · Post edited by Rodolfo Pilas at 2011-11-03 20:58:35

I receive an error form command:

$ /usr/lib/airtime/pypo/bin/liquidsoap_bin/liquidsoap 'output.icecast(%mp3, mount="test.ogg", host="164.73.X.X", port=8888, password="Pass", mksafe(single("/var/lib/airtime/tmp/airtime_mvc/application/models/tests/test10003.mp3")))'
At line 1, char 101: the variable mksafe used here has not been previously
defined.

I also have tryed change mksafe() with sine(). as I seen into other example at this formum:

$ /usr/lib/airtime/pypo/bin/liquidsoap_bin/liquidsoap 'output.icecast(%mp3, mount="test.ogg", host="164.73.X.X", port=8888, password="Pass", sine())'

Sorry, the previous command was missing something. Try this:

/usr/lib/airtime/pypo/bin/liquidsoap_bin/liquidsoap /usr/lib/airtime/pypo/bin/liquidsoap_scripts/library/pervasives.liq 'output.icecast(%vorbis, host = "localhost", port = 8000, password = "hackme", mount = "liq.ogg", mksafe(single("/var/lib/airtime/tmp/airtime_mvc/application/models/tests/test10003.mp3")))'

Rodolfo Pilas · Post edited by Rodolfo Pilas at 2011-11-06 09:44:09

Thank you Martin. I understand that the command connects and starts the source to the icecast server:

$ /usr/lib/airtime/pypo/bin/liquidsoap_bin/liquidsoap /usr/lib/airtime/pypo/bin/liquidsoap_scripts/library/pervasives.liq 'output.icecast(%vorbis, host = "164.73.X.X", port = 8888, password = "Pass", mount = "liq.ogg", mksafe(single("/var/lib/airtime/tmp/airtime_mvc/application/models/tests/test10003.mp3")))'

Martin Konecny

This is really strange. Everything looks perfectly set up. Please run the following command:

/usr/lib/airtime/pypo/bin/airtime-liquidsoap

and post the entire output.

Rodolfo Pilas

OK... when I run the command as user, it can not include cfg file because it is root read-only.

$ /usr/lib/airtime/pypo/bin/airtime-liquidsoap
Line 2, char 39: cannot %include, file "/etc/airtime/liquidsoap.cfg" doesn't exist.

Use ignore(...) instead of output_stereo = ... if you meant to not use it.
Otherwise, this may be a typo or a sign that your script does not do
what you intend.
#

I have played, and when I change /etc/airtime/liquidsoap.cfg permission to 644 it works!! I have now a running LIQUIDSOAP process.

Let me do several test before to label this post as SOLVED.

Martin Konecny

Did you fix it by putting the comment back in front of "output_stereo" variable in /etc/airtime/liquidsoap.cfg?

It looks like this variable isn't used anymore, and we should have removed it in 1.9.4.

Rodolfo Pilas

No, I lived the /etc/airtime/liquidsoap.cfg unchanged, at it is showed before.

I just changed the file permission to 0644.

Rodolfo Pilas

THANK YOU VERY MUCH Martin!

Howdy, Stranger!
