Need help to build liquidsoap - Airtime Support Discussions on Sourcefabric Forum

Hi

I need to transcode to aac when streaming

So i have followed the wiki to build liquidsoap, but i don't know where to copy the new builded folder

thanks

Martin Konecny

You simply need to copy the liquidsoap binary file src/liquidsoap from some place on your drive. Then use the following commands:

rm /usr/bin/airtime-liquidsoap

ln -s /path/to/custom/liquidsoap /usr/bin/airtime-liquidsoap

Albert FR

do a rm is not perhaps a good idea ;-)

mv /usr/bin/artime/liquidsoap usr/bin/airtime/liquidsoap-old

is more secure ;-)

Thanks

One last thing
then I need to modify my ~/airtime/pypo/scripts/ls_config.liq to make the change

mountpoints
mount_point_mp3 = "airtime.mp3"
mount_point_vorbis = "airtime.ogg"
###mount_point_aacplus = "airtime.aacp"

but i can't find this file

It is simply a symlink, so it is ok :)

Reply to @lechevo:

Those instructions are a little out of date.

Now that you've compiled Liquidsoap with AAC plus support, I think it is simple enough to just open /usr/lib/airtime/pypo/bin/ls_scripts/ls_lib.liq and replace "%mp3" with "%aac+" on all lines between 95 and 115.

This will play AAC+ whenever you choose MP3 via the Airtime web UI which is a temporary hack until we bring in better support for alternative streaming formats.

hi

i have made the changes, then i restarted airtime and liquidsoap

and i can't hear any sound when i stream

here is what i can see in the /var/log/airtime/pypo/pypo.log

Run

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

and it will tell you what is wrong with the modification. You can also post the output here.

lechevo · Post edited by lechevo at 2012-08-29 12:44:53

Are you sure i need to do

"%mp3" with "%aac+"

or

"%mp3" with "%aacp"

lechevo

Maybe here is the problem

dpkg-reconfigure airtime

...

Liquidsoap symlink points to the wrong place, fixing it!

Albert FR

ln -s /usr/bin/liquisoap /usr/bin/airtime-liquidsoap

Hey, I got this:

Hi,

I have modified ls_lib.liq such that i will get tile of stream as artist|title. But it is not getting reflected. I am getting it as artist - title. Please help me. Below is the method i changed. After changing i have restarted airtime also.

def append_title(m) =

log("Using stream_format #{!stream_metadata_type}")

if !stream_metadata_type == 1 then

[("title", "#{!show_name} - #{m['artist']} - #{m['title']}")]

elsif !stream_metadata_type == 2 then

[("title", "#{!station_name} - #{!show_name}")]

elsif !stream_metadata_type == 0 then

log("In Case Of 0")

[("title", "#{m['artist']}|#{m['title']}")]

else

log("Using New stream_format #{!stream_metadata_type}")

[("title", "#{m['artist']}|#{m['title']}")]

end

Anyone out there have reliable success with he-aac on 2.3 + LS 1.1.0 yet? When I tried this with the previous versions, liqsoap broke the connection or restarted between each and every track. Super annoying. :(

Martin Konecny

which AAC encode were you using? AFAIK there are 6 different versions for Linux.

libaacplus2 - although if there's a better one out there, I'd love to hear it.

Martin Konecny

Now that you mention it, there used be a bug where Liquidsoap crashed after every track with AAC. I believe this has been fixed though. Why don't you try again, and let us know how it goes. We will be looking into implementing AAC HE support soon, and could learn from your experience on the best approach as well as encoder.

Steps to get latest version of Liquidsoap are available here:

Has this been tested to work with LS1.1.0?

*** bootstrapping ocaml-cry
/bin/sh: 1: ./bootstrap: not found
make: *** [ocaml-cry/configure] Error 127

Martin Konecny

There appears to be a problem with the Liquidsoap repository at the moment.

Roger Wilco

Ah! That explains that! Repo issue aside, to get going with 1.1.0 and 2.3 then, is this the best install sequence?

sudo nano /etc/apt/sources.list
deb http://apt.sourcefabric.org/ precise main

sudo apt-get update

[make/install libaacplus]

[make/install ls]
append:
sed -i "s/#ocaml-aacplus/ocaml-aacplus/g" PACKAGES

sudo apt-get install sourcefabric-keyring

sudo apt-get install postgresql

sudo apt-get install airtime

Voila‽

Martin Konecny

You will also need to install the aacplusenc library. You can get it from medibuntu:

http://www.medibuntu.org/

It's not a free package and therefore not in the Ubuntu/Debian repositories.

Actually appears that you need to get the library from here:

Edit:

Verified as working - download version 2.0.2 untar it and then run

./autogen.sh

./configure

make

sudo make install

Not sure how that happened, but there is something wrong with your /etc/apt/sources.list file. You need to check which architecture your OS is targetting (amd64 or i386), and then remove the incorrect line.

Yes it is a script. You could simply paste it into a file, and then run "bash script.sh" to execute it.

Toronto... we have lift off... :)

Well, sort of. %mp3 connects and works fine but LS simply refuses to start if I change things over to %aacp. What's the proper full syntax? Tried following this and some minor variations and couldn't get it to respond.

Martin Konecny

Try

%aacplus(bitrate=64)

Roger Wilco

ignore(output_stereo(%aacplus(bitrate = 24), !source))

No dice :(

Martin Konecny

Try running

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

and post the output.

That last output you posted looks fine. You should be able to output aac now.

Roger Wilco

Yeah? The On Air light comes on briefly at the start of a track then immediately goes out. Icecast receives a handshake from LS but nothing is actually streamed or transferred. :(

Martin Konecny

Anything in liquidsoap logs?

Anyone else out there rocking libaacplus2 + AT2.3.0 + LS1.1.0 ?? @-)

Martin Konecny

Those outputs look fine to me.

Yeah? The On Air light comes on briefly at the start of a track then immediately goes out. Icecast receives a handshake from LS but nothing is actually streamed or transferred.

Can you elaborate? What do you mean handshake? Does the mount point show only metadata?

I haven't tried faac yet, but aacp2 definitely does not work. At the start of a track, the On Air light in the HTTP interface changes to ON, then 1-3 seconds later, the light goes out. Icecast does get a connection attempt from Liquidsoap (connected time shows >0 seconds) but total_bytes_read/send stays firmly at 0. System>Status>airtime-liquidsoap
Uptime remains "0d 0h 0m 0s" as well.

If Liquidsoap isnt running it should at least show in the logs that it
cannot startup or has shutdown. Can you verify this again. Also check to
make sure there arent two liquidsoap processes running.

Anyone get faac working? How does it compare to lame?

this works ..with aac+ .. I think the only issue was turning off the a flag on the aacplus library build .. installed a version of KH icecast to suit . and added nasty hack on the tail of ls_scipt.liq which allowed to bypass the frontend.. everything seems to work fine..defaulted to 64k ...

output.icecast(%aacplus,
host = "127.0.0.1", port = 80,
password = "xxxx", mount = "din3.aacp",
fallible=true,
description = "xx",
genre = "din_core",
