AAC+ FAQ update - Airtime Development Discussions on Sourcefabric Forum

Re: How do I add an AAC stream?

http://wiki.sourcefabric.org/display/CC/FAQ+and+Support

For version 1.8.2 I made these path corrections:

Original:
Quote:

Go to ~/airtime/pypo/liquidsoap/ and backup liquidsoap32.

Copy the newly compiled liquidsoap from liquidsoap/src to ~/airtime/pypo/liquidsoap/liquidsoap32

Then I modified my ~/airtime/pypo/scripts/ls_config.liq where it shows "###". Remove the "###" for it to work.

Then add the following to the end of ~/airtime/pypo/scripts/ls_scripts.liq:

Update:
Quote:

Go to ~/airtime/python_apps/pypo/liquidsoap/ and backup liquidsoap32 (or liquidsoap64 on a 64bit install).

Copy the newly compiled liquidsoap from ~/savonet/liquidsoap/src to ~/airtime/python_apps/pypo/liquidsoap/liquidsoap32 (or liquidsoap64 on a 64bit install).

Then I modified my ~/airtime/python_apps/pypo/scripts/ls_scripts.liq where it shows "###". Remove the "###" for it to work.

Then add the following to the end of ~/airtime/python_apps/pypo/scripts/ls_scripts.liq:

Hope I caught everything.

You can run

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

and see what error messages appear.

Martin Konecny

Ah ok,

I thought you already replaced the Airtime Liquidsoap with your own version. Yes you need to do that, since we didn't compile AAC support into our Liquidsoap.

Simply overwrite /usr/lib/airtime/pypo/bin/liquidsoap_bin/liquidsoap with your custom version.

I'm reading it

a little thing

music = playlist(mode='randomize',reload=1,reload_mode="rounds", "/srv/users/music")
jingles = playlist(mode='randomize',reload=1,reload_mode="rounds", "/srv/users/jingles/")
default = rotate(weights=[1,5], [jingles, music])

randomize and round are better than random (cf liquidsoap wiki)

and you can do :

jingles = playlist(mode='randomize',reload=1,reload_mode="rounds", "/home/server/muzyka/jingles")
music_zaiks = playlist(mode='randomize',reload=1,reload_mode="rounds" "/home/server/muzyka/zaiks")
music_cc = playlist(mode='randomize',reload=1,reload_mode="rounds" "/home/server/muzyka/cc")

default_zaiks_cc = rotate(weights=[1,3,1,3], [jingles, music_zaiks, jingles, music_cc])

Thanks! I've updated the wiki.

Hello!

I have tried this but that does not work. I done this in that way:

1.Builded liquadsoap like here http://wiki.sourcefabric.org/display/CC/Building+Liquidsoap+from+Mercurial

I have tested by command ./liquidsoap 'output.icecast(%aac+, mount="test.aacp", sine())'

And it is working!

2. I made entry in /etc/airtime/liquidsoap.cfg

mount_point_aacplus = "airtime.aacp"
output_icecast_aacplus = true

3. Entry in /usr/lib/airtime/pypo/bin/liquidsoap_scripts/ls_script.liq

And here I'm not sure if I did it correctly

if output_icecast_aacplus then

ignore(output.icecast(%aac+,

encoding = "UTF-8",

host = icecast_host,

port = icecast_port,

password = icecast_pass,

mount = mount_point_mp3,

fallible = true,

restart = true,

restart_delay = 5,

url = icecast_url,

description = icecast_description,

genre = icecast_genre,

s)

)

end

------------------------------------------------------------------------------------------------------------------------------------------------------

So It's look ok, but don't work. Any idea?

Your mount should use the "mount_point_aacplus" variable.

krzakx

aaa... yeap! I just discover it too...

But it still do not work.

There was script to check ls_script.liq how to run it?

krzakx

And everything is clear

krzakx@krzakx:~/savonet/liquidsoap/src$ sudo -u pypo /usr/lib/airtime/pypo/bin/airtime-liquidsoap

Invalid value at line 78, char 27-31: No encoder found for that format.

krzakx@krzakx:~/savonet/liquidsoap/src$ sudo gedit /usr/lib/airtime/pypo/bin/liquidsoap_scripts/ls_script.liq

But why ./liquidsoap 'output.icecast(%aac+, mount="test.aacp", sine())' is working?

The problem is with compiled liquidsoap?

Martin Konecny · Post edited by Martin Konecny at 2011-11-16 21:06:42

Let us know if it works, I have a feeling that even though Liquidsoap will play it, we may need to change Airtime to allow an extensions other than mp3/ogg.

krzakx

eh...

I do not understand

krzakx@krzakx:/usr/lib/airtime/pypo/bin$ sudo -u pypo /usr/lib/airtime/pypo/bin/airtime-liquidsoap

At /usr/lib/airtime/pypo/bin/liquidsoap_scripts/library/shoutcast.liq, line 41, char 20:

cannot apply that parameter because the function

(at /usr/lib/airtime/pypo/bin/liquidsoap_scripts/library/shoutcast.liq, line 36, char 17)

has no argument labeled "restart"!

krzakx@krzakx:/usr/lib/airtime/pypo/bin$

I do not have active Shoutcast, I am using only Icecast
eh... is so difficult.

Albert FR

check your ls_script.liq
some errors inside

krzakx

eh.... it seems OK for me. Please check http://wklej.org/id/629231/

Albert FR

but effectively is not for a switching system ;)

Albert FR

what said

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

humm...

the first thing to do :

change
#output_shoutcast = false

into
output_shoutcast = false

and how do you install your last airtime ?
mannually ? or by apt-get ?
You have recompiled liquidsoap for AAC support, but have you replaced the old one ?

krzakx

1. Done now is output_shoutcast = false (it was before like this, but I have tried many options and I hashed it)

2. Last AirTime is from repo by apt-get

3.yeap, a copy new compiled liquidsoap with AAC package to /usr/lib/airtime/pypo/bin/liquidsoap_bin and from here I can do this ./liquidsoap 'output.icecast(%aac+, mount="test.aacp", sine())'

And it's work!

Albert FR I am making new system admin user for you :) on server that will be quicker.

Also please take look in randomize and round are better than random (cf liquidsoap wiki), becasue I have do in this way and.... not working.

Albert FR

krzakx
that's really strange because randomize and round work really for my servers ...
Ok for admin user
I'll looking that this evening

By the way, the latest stable LS (1.0.0) seems really doesn't have restart and restart_delay option in output.icecast(...)

http://savonet.sourceforge.net/doc-1.0.0/reference.html

Check output.icecast(...)

i was fighting this for some days before i got it work.

Martin Konecny

Yes Romeo is right, you will have to remove the restart and restart_delay parameters. Everywhere from the code. After that it should work.

Albert FR · Post edited by Albert FR at 2011-11-17 10:59:27

Martin, Romeo we are agree with the fact that's only work/bug with 1.0.0 and not 1.0 beta2 (available on ubuntu LTS /debian 6) ?
isn't it ?

Martin Konecny

It's not a bug for 1.0, it's just that there were some changes to the Liquidsoap API, and restart, restart_delay aren't required anymore.

Albert FR

for 1.0.0 (stable) then
and not for 1.0 beta2 (ubuntu 10.04 LTS / debian 6) or 1.0 beta3 (ubuntu 11.04 & 11.10)

do you plan to distribute an liquidsoap up of date with airtime in a near future (debian/ubuntu package) ?

krzakx
, is good for you now ?

Paul Baranowski

"do you plan to distribute an liquidsoap up of date with airtime in a near future (debian/ubuntu package) ?"

Yes :)

Albert FR

that's a really good news !!!

Hello everyone again!

How was the holiday season? At this free time I was little work around the ACC+ support and... I still don't get this working.

By the way after after returning to this topic, it is hard to find me because system of points/votecomments destroyed posts chronological. Is there any solutions to disabled it?

Back to ACC+

I have done every steps one more time on another fresh Ubuntu machine.

1.Installed AirTime from repo.

2. Build LiquidSoap like here https://wiki.sourcefabric.org/display/CC/Building+Liquidsoap+from+Mercurial with ACC+ PACKAGE.

And tested it ./liquidsoap 'output.icecast(%aac+, mount="test.aacp", sine())' .It's working.

3.I had overwrite /usr/lib/airtime/pypo/bin/liquidsoap_bin/liquidsoap with my custom version.

And removed from everywhere in code restart and restart_delay parameters

And it doesn't work :(

krzakx@krzakx-laptop:~/savonet/liquidsoap/src$ sudo -u pypo /usr/lib/airtime/pypo/bin/airtime-liquidsoap

At line 54, char 23: the variable output.alsa used here has not been

previously defined.

EDIT!

I get it workin! I hashed the parameters connected with alsa device in liquadsoap.cfg and ls_script.liq. And now is working, but for what are these parameters? And can they be hashed?

Fisrt attached file is broken.

Verheek

Glad to hear it's working.

I have not played with this since 1.8.2 so I can't comment. I did try experimenting in 2.x.x but found that more work was needed as the settings were made in the web browser and one of these needed to be modified to accept AAC+.
