Argentiina :) Thanks for your work Romain, I really look forward to making liquidsoap cry, the shouting became really annoying! Here is the (fixed) changelog ! Switched to custom implementation of the shout protocols ! New with this: * Support for arbitrary headerless formats using content-type and external encoding process * Wrappers updated for lame and shoutcast, added custom irc, aim and icq headers for shoutcast. fixes #192 * Added wrappers for icecast and shoutcast using aacplusenc. fixes #220 and #136 * Completely rewrote external encoder start/stop mechanisms. Now relies strictly on the encoding process' good behaviour. See (updated) documentation for more details. * Added restart_encoder_delay to regulary restart the encoder. Useful for lame and aacplusenc encoders since they tend to fail after some time. Defaults to 3600 seconds for these encoders. Of course, this might not be bug prone, so feel free to test and report :) Enjoy ! Romain -- Say I remember, when we used to sit, In the gouvernement yard in Trenchtown, (...)

Re: [Savonet-users] Stopping dynamic.request from prefetching songs
Le Wednesday 08 April 2009 20:44:41 Robert McAuley, vous avez écrit :
Hello all,
Hi !
I run a radio station where users request and then vote for what song
they want to hear next. The voting part is critical - each song is
run through an election, and then that song is played immediately as
the next song. The process is controlled via an executable program,
and I have been using Ices' script input to handle this.
This immediate decision process is the problem I am having with
LiquidSoap and its dynamic.request input. On start of LiquidSoap, it
executes the script twice, always keeping one song in queue ahead of
the one currently playing. This makes the voting process on my site
not immediate, which is not desired behaviour from my perspective.
I have tried setting the length setting to 1., however, that
hasn't changed the prefetching behaviour.
Is there a way to stop dynamic.request from prefetching? Or must I
use JACK or something similar to make sure LiquidSoap does not try
prefetching?
Ok, I understand a bit better now your issue :)
Have you try to reverse the behaviour ? I mean that, instead of letting
liquidsoap pull the next song, use a request.{queue,equeue} and push the
songs as soon as they are elected ?
In this case, the behaviour should be much more immediate, but you would have
to provide a fallback source for the cases when there are no next song on the
queue..

Re: [Savonet-users] Taglib problem, svn upgrading problem
Le Monday 13 April 2009 19:27:18 Austin Seraphin, vous avez écrit : Hi. Hi ! I've recently begun using Liquidsoap. I upgraded from an older svn version to the latest stable 0.9..0 release. When I did, I noticed errors like the following: TagLib: MPEG::Header::parse() -- Invalid sample rate. TagLib: MPEG::Properties::read() -- Page headers were invalid. These happen when trying to read .ogg files, so I'd guess that liquidsoap tries to use taglib's mp3 tagging on the wrong file format, hence the errors. Unfortunately, these errors keep outputting on the console, making it unusable for anything else. Hmm.. These messages are not really an issue. If you don't like them, I think you should simply run liquidsoap in a screen, as a daemon, or simply telling it to redirect its messages to /dev/null: liquidsoap (...) /dev/null 21 I then tried upgrading to the latest svn, and ran into another interesting problem. After building it, it could not find output.icecast.vorbis, and related icecast and shoutcast output plugins. I asked on the #savonet channel, and someone suggested using ocaml-cry instead. I added this to the PACKAGES file, after seeing it in the PACKAGES.default file. Firstly, ocaml-cry didn't have a valid configuration file. An error on line 32 (if memory serves) of the main ./configure script said @echo instead of echo. It couldn't find the configure script for ocaml-cry, so I used autoconf to build it. The configuration and making worked for ocaml-cry, but then later on, it gave this: In outputs/icecast2.ml: Error: Unbound value Cry.ogg_audio So there you have my current state. I don't know if upgrading to the latest svn will fix my taglib problem, and the ocaml-cry has some related issues. I hope this email helps. your problem with ocaml-cry comes from the fact that you need to bootstrap again. Hence, you should do again the whole compilation process, from the toplevel, which is: ./bootstrap ./configure make clean make The current state of the toplevel build, with PACKAGE.default, is not really useful. We should do something about it soon.. Romain -- This SF.net email is sponsored by: High Quality Requirements in a Collaborative Environment.

I've been checking out this script. It's interesting!
http://savonet.sourceforge.net/doc-svn/dolebrai.html
What language is the liq script based on? It's unlike anything I'm used to.
Well, it is a liquidsoap script, so the language is liquidsoap itself :)
I've read about specific functions in the API docs, but I'm still
unclear. These areas for example
###
default = single(id=default,default)
s =
request.dynamic(id=scheduler,default_duration=30.,length=1.,
fun () -
request(get_process_output(#{scripts}/scheduler.pl 2
#{scripts}/log)))
s = fallback([ request.queue(id=q), s, default ])
###
default = single(id=default,default)
I understand what is happening here, you're taking an individual mp3
file, and setting up to be a source.
s =
request.dynamic(id=scheduler,default_duration=30.,length=1.,
fun () -
request(get_process_output(#{scripts}/scheduler.pl 2
#{scripts}/log)))
This is a little confusing to me. I understand this is probably the
source which calls a perl script, which queries your database and
outputs a result in the annotated format you mentioned. I don't
understand the purpose of fun(). I noticed fun() is defined in an
add_protocol function, and is setup to take parameters. Though no
parameters are passed in though request.dynamic, at least not in a way
I understand. Can you explain what's happening here?
Well, you basically got it right :)
fun is a keyword specific to functional language. In fact:
fun (x) - print(x)
is equivalent to:
def f(x) =
print(x)
end
It is not really equivalent in the sense that there can be syntactic side-
effects, but that's the idea..
Hence, here:
fun () -
request(get_process_output(#{scripts}/scheduler.pl 2 #{scripts}/log))
Is a function that takes no value and returns a new query.
In particular:
get_process_output: returns the output of the script.
request: create a request based on the output of this script.

I think I get it. fun - is a way to create a anonymous function, and
you'd probably use fun() - if your function code is only a single
line and used in one place. You would go with a full def, if your
custom function were more advanced or was used repeatedly. Correct?
Yep !
add_protocol(dolebrai,
fun (arg,delay) -
get_process_lines(#{scripts}dolebrai-filename #{quote(arg)}))
In this case, the function has two args, arg and delay. How are the
values for those arguments being supplied? I don't see any explicit
calls to to add_protocol.
Yes. This function registers a new request protocol. It will be used when a
request of the form: dolebrai:arg is received.
The two arguments are the arg (part after dolebrai:) and the delay for getting
the song (usually 60 seconds). This possibility is very useful if you want to
extend liquidsoap's capabilities for fetching songs or applying a treatement
to the song.
I'm not sure there if you sense much need for this, but if you help me
understand the language I can try to write a code generator for simple
use cases. Maybe something something like a config file that defines
how you want tracks rotated, backup sources and so on, and a ruby
script (that's what I use most) that generates a .liq based on
contents of config.
Héhé, nice idea.
I have written a similar thing which you can find here:
http://savonet.rastageeks.org/browser/trunk/liq-contrib/simpleliq.in
However, it is nothing serious and was just a proof-of-concept.
But, clearly, a tool to generate a script based on some fixed parameters would
be a great thing for newcomers who don't want (yet) to program their streams
but still benefit from the flexibility :)

Hence, sending AAC is not properly supported: we send the right audio data but the server does not treat it correctly -- or at least the listener does not get it as AAC, I'm not sure. In any case, this is fixed with the SVN version which now uses our own version the shout library, allowing to pass the correct mime-type and get proper AAC streaming through icecast.

Re: [Savonet-users] How can one play a playlist just o nce, and reload it each time it's called
Le Wednesday 13 May 2009 13:33:55 Kero, vous avez écrit :
Hello,
Hi !
Writing here as suggested on IRC.
Here is the deal :
I'm running a webradio with a music playlist most of the day, and some
live shows usually during the evening. These show can last from 1 to
more than 7 hours, it all depends on the mood of the DJ.
All live shows are saved by liquidsoap in different files using
output.file.mp3
Now, I would like to be able to rerun my shows during nights and
afternoons. It has to stop and go back to the main playlist once the show
has been entirely rebroadcasted. And also at special hours, even if the
rebroadcast is still running.
So I was thinking of something like :
pre_rerun = playlist.once(path/rerun.m3u)
music = playlist(path/music.m3u)
true_rerun = fallback([pre_rerun, music])
switch([ ({10h00-16h00}, music),({16h00-20h30},
true_rerun),({20h30-3h00}, music),({3h00-10h00}, true_rerun)] )
The main problem is : playlist_once has no way of reloading rerun.m3u
- so it would play the same playlist everyday even tho the files are
changing.
It is even worse: playlist.once will not be available any more when it has
finished, so that you shall need to restart liquidsoap..
I've heard there was a workaround for this, a way to force a playlist
to run only once per switch while being regularly reloaded. I would be
interested by such a solution. :-)
For this case, I have another idea in mind. You should be able to perform
something relatively simple using a queue of request and a recursive task.
Something like:
rerun = request.queue(id=rerun)
Now the trick is to register a recursive task for adding the new live shows.
Roughly, something like:
def add_live() =
# We check if it is time to push a request
if 16h00-20h30 or 3h00-10h00 then
# We check if we are already running a live
ret = list.hd(server.execute(rerun.queue))
if ret == then
# We get the file/uri to play (can be a obtained from a script or
# anything else)
file = (...)
# We push the request
ignore(server.execute(rerun.push #{file}))
end
end
# We run again in one minute
60.
end
Eventually, we register the task:
add_timeout(60., add_live)
The purpose of this recursive task is to feed the rerun source. It will feed
it if it is the correct time for broadcasting the live archive, and only if
another archive is not already being played.
When an archive ends, within at most one minute, if it is still time, it will
start another live.
We could also check the duration of the file, using file.duration, and if there
is not enough time for it, don't push it, but I am nto sure there is a
function for that in the language for now..
Eventually, we can add the switch that will make sure we play the archive at
the correct time:
# This transition skips the current track when switching..
def transition(a,b) =
source.skip(a)
# This eats the last remaining frame from a
sequence([a,b])
end
full = switch(track_sensitive=false, transitions=[transition,transition],
[({16h00-20h30 or 3h00-10h00}, rerun), ({true}, music) ])
We set track_sensitive to false to make sure that the switch can occur in the
middle of an archive. We could set it to true if we check for available time
before starting a live, as explained above.
The transition function is also needed when track_sensitive is false. It makes
sure that if switching back to music in a middle of an archive, then this
track is skiped, such that the next time we play an archive, it starts with a
fresh one.
I did not test the code above, but I think it should mostly be correct. Let me
know if you need more details.. I may also add something inspired by that in
the standard library.

Re: [Savonet-users] normalize/skip_blank
Le Friday 15 May 2009 02:05:51 Brandon Casci, vous avez écrit :
Hello
Hi !
If you choose to use normalize and skip_blank, do you need to apply
them for each playlist, or can you apply them to the whole chain of
playlists?
In general, skip_blank can be used on the top level of your playlists.
The same applies for normalize.
However, you should not apply skip_blank on the last source before an output
if this source includes live sources, such as input.http or input.harbor. For
these sources, skipping would not work. Normalize should work, however, but
you should care about sound issues when normalizing. More details there:
http://savonet.sourceforge.net/doc-0.9.0/replay_gain.html
For example..looking at the case study from the website
(...)
radio = add(normalize = true, [radio, switch([({0m0s},clock)])])
Beware that the meaning of the normalize parameter here is not the same as the
meaning of the normalize operator. In add, normalize means that, when adding
for instance a and b, the resulting sound samples are normalized, in the form:
a + b / 2
Without normalization, the resulting samples are simply:
a + b

Re: [Savonet-users] Liquidsoap on FreeBSD
Hi !
Thanks for you detailled report. Here are some comments:
Le Tuesday 26 May 2009 05:30:10 Andrew, vous avez écrit :
In order to get configure to go through cleanly I had to use this
configure command:
CFLAGS=-I/usr/local/include LDFLAGS=-L/usr/local/lib CPPFLAGS=-I/
usr/local/include ./configure
Ok. That is probably normal.
To compile with OSS support I needed to create /usr/src/include/linux
and copy the following sound include files there:
cp /usr/src/sys/dev/sound/pcm/sound.h /usr/src/include/linux/sound.h
cp /usr/src/sys/sys/soundcard.h /usr/src/include/linux/soundcard.h
Could you check with the attached patch if it fixes oss compilation for you
without this hack ?
With the LDFLAGS on the command line I was able to make it go through
the configure process successfully, however make would continually fail.
To fix the issues with make I had to symlink the following libraries
from /usr/local/lib to /usr/lib
ln -sf /usr/local/lib/libmp3lame.so /usr/lib/libmp3lame.so
ln -s /usr/local/lib/libmad.so /usr/lib/libmad.so
ln -sf /usr/local/lib/libogg.so /usr/lib/libogg.so
ln -sf /usr/local/lib/libvorbisenc.so /usr/lib/libvorbisenc.so
ln -sf /usr/local/lib/libvorbisfile.so /usr/lib/libvorbisfile.so
ln -sf /usr/local/lib/libshout.so /usr/lib/libshout.so
ln -sf /usr/local/lib/libfaac.so /usr/lib/libfaac.so
ln -sf /usr/local/lib/libfaad.so /usr/lib/libfaad.so
ln -sf /usr/local/lib/libsamplerate.so /usr/lib/libsamplerate.so
ln -sf /usr/local/lib/libtag.so /usr/lib/libtag.so
ln -sf /usr/local/lib/libtag_c.so /usr/lib/libtag_c.so
Ok. We had found the issue for this some times ago.
I just made a big commit on trunk/ in order to fix this.
Could you try with the latest SVN trunk if you can compile without this hack ?
This fixed the problems of finding codecs and such, however despite
specifically compiling using gmake it would try and use the FreeBSD
make instead. This forced me to temporarily rename the BSD version and
symlink gmake:
mv /usr/bin/make /usr/bin/make.good
ln -sf /usr/local/bin/gmake /usr/bin/make
make
Hmm..
We have tried to remove all hardcoded make calls. Apparently there still are
some of them..
Could you send us the compilation logs where this fails so that we can fix them
?
And lastly in order for 'make install' to work I had to add a user and
group named liquidsoap using adduser:
adduser
make install
Hmmm..
So far, this part is assumed to be done by the user/administrator:
# User ${user} and group ${group} are expected to exist.
# They are defined in Makefile.defs, written by configure.
However, since you are not the first to complain, I wonder whether this could
be done in a better way..
This produced a working /usr/local/bin/liquidsoap binary that worked
with OSS audio input.
Good ! You seemed quite patient :)
For some reason though I had to remove the /usr/local/lib/liquidsoap/
0.9.0/utils.liq file as the program would just hang there with it in
place.
That is really strange.
Using liquidsoap without utils.liq will be mush less usefull. A lot of useful
functions are defined there.. It would be good to debug and fix this issue..
Do you have more informations ?

Unfortunately it did not. I got this:

I just tried SVN revision 6591 and that seems to have fixed things.
However I did need to run gmake with the LDFLAGS:
CFLAGS=-I/usr/local/include LDFLAGS=-L/usr/local/lib CPPFLAGS=-I/
usr/local/include gmake
after that it compiled cleanly without having to make any symlinks to
libraries or gmake.
Great !
It seems strange that you still need to pass the compilation variables.
However, this is far much better..
Hmmm..

I think if there was some information in INSTALL that would be
suitable. It just threw me off because I wasn't expecting that.
Yes. I think we should detect when the user/group does not exist and issue an
error in this case..
The LDFLAGS on the command line was also a bit non-intuitive as I'm used
to libraries being automatically discovered when running ./configure --
prefix=/usr/local. It's not a big deal though.
Ok, I will look at that.
That is really strange.

The SVN releases seems to have fixed this issue as well.
Good !
One note. With ocaml-faac and ocaml-faad enabled in PACKAGES it would
not compile cleanly. I don't particularly need regular AAC so that is
ok for my purposes, but I thought I would report it:
Ok, will look at that.

Re: [Savonet-users] External aacplusenc on FreeBSD
Le Tuesday 26 May 2009 13:47:33 Andrew, vous avez écrit : Humm... The external mechanism is pretty complicated. I am not surprised it does not work out of the box. For a start, could you try to test with the latest SVN trunk code ? This part has been rewritten recently, and there were important changes in the implementation. SVN release 6591 appears to have resolved the issue here. Aacplusenc how works. Good ! One bug that I discovered with it on both Linux and FreeBSD was that it does not restart correctly using the restart_encoder_delay field. With this set to 3600, I got: 2009/05/25 20:39:40 [output(dot)icecast(dot)aacplusenc:3] Restarting encoder after delay (3600s) encoding finished And it never did restart. I also have these values in my config (as in my previous post); ~restart=true, ~restart_delay=3 ~restart_on_crash=true, ~restart_on_new_track=false, ~restart_encoder_delay=3600 Hmm. I need to debug this more. Will try to look more in details. Of course, any patch/contribution is welcome :) With a working restart_encoder_delay will there be any cutouts in the audio while the encoder restarts or will liquidsoap just continue to store audio in the buffer as it comes in from the soundcard and then pump it out to the encoder once it comes back up? There should not be any loss, from the point of view of liquidsoap, the encoder is just restarted, but no audio is lost. For the player, however, there can be a glitch. I understand that the hourly restart is due to bugginess with aacplusenc. Is this because it's a child process instead of a library? Yes ! Perhaps it would be useful to use libaacplus instead? I know that's what the Darkice project is using: http://lists.tyrell.hu/pipermail/darkice-list/2008-November/000314.html Haha ! I initially looked for such wrapper to turn aacplusenc into a library. However, upstream communication was not very sucessful, and I decided to switch to external encoders for that reason. I do not know f it is a good idea to use this library: its API might change, or support get lost.. However, any contribution on this topic would be of course welcome. For myself, I do not know yet if I want to bind this library. Romain -- Register Now for Creativity and Technology (CaT), June 3rd, NYC.

In order to inject metadata into your source, you can use the insert_metadata
operator.
You enable it by adding in your script:
radio = insert_metadata(id=radio, radio)
That way, the radio source is redefined with the possibility to inject
metadata.
When running the script with the telnet server enabled:
set(server.telnet, true)
you should be able to connect to the port 1234 on the localhost:
telnet localhost 1234
This should open a console where you can type commands. For instance help
will return the list of available commands. Also, some commands are self-
documented, so you can ask for their documentation.
In your case, you can then insert metadata, for instance:
radio.insert title=foo,artist=bar
For advanced usages, you can also execute this command within the script it
self, using the server.execute operator:
server.execute('radio.insert title=foo,artist=bar')
This operator returns the strings corresponding to the output of the command.
Usually you don't care about them and you ignore the output:
ignore(server.execute('radio.insert title=foo,artist=bar'))

Re: [Savonet-users] Metadata update according with live show info

Hi, Savonet Team!
Hi !
is it possible to update stream metadata using input.harbor headers?
i suggest i must do it this way, but it doesn't work. i get blank title
instead.
Yes, the liquidsoap language is a functional language. Hence, it is not
possible to change the value of a variable. This is done by redefining a new
variable.
For that reason,
x = y
is a boolean, true if x = y and false otherwise.
In some cases, however, this is not possible to redefine the variable
You can use the string.ref operator. This operators returns two functions, one
for reading the current registered value, and another one to register a new
value.
In your precise case, you can do even better, and avoid string.ref. This goes
like this:
def liveStart(headers)
log([LIVE-START]: live source goes up! Switching from playlist...)
title = headers[ice-name]
ignore(server.execute(liveMeta.insert title=\#{title}\))
end
liveInput = input.harbor(id=live,
live.ogg,
buffer=10.,
password=livePasswd,
on_connect=liveStart)
liveInput = insert_metadata(id=liveMeta, liveInput)
That way, a new metadata will be inserted each time the harbor input receives
a new connection.

Re: [Savonet-users] Weird problems when calling a playlist of only 1 title
Hi ! Le mercredi 10 juin 2009 02:46:55, Kero a écrit : My guess is : each time this playlist is refreshed, the bug makes the refresh going a little worse. At the beginning it's not that bad, but after a few dozens (hundreds?) of refreshes, liquidsoap really starts to lose control. Your analysis was correct. While preparing another commit (a nice surprise that David suggested), I realized there was a bug in the feeding task for the queued source and also the playlist source. Basically, the feeding was not doing what we wanted it to do, resulting in the possibility to spawn an important number of parrallel refresh when the initial request was failling..

Thanks to a very good suggestion from David, this should be fixed now ! Indeed, now queued sources (request.queue, request.equeue and playlist) take the estimated remaining time into account for fetching new files. This means that now these sources may fetch much less files in advance. By default, the first file should be sufficient. It can happen that two files are queued from time to time due to the estimated nature of the remaining time, but this should be very minimal. This also mean that now the secondary queue, the one that you can edit in request.equeue, should contain all queued files, and the primary_queue only the file currently being played. Default values have also been changed to enable this new behaviour. You can fallback to the old behaviour by setting back to old values (length=60.) and setting the new conservative option to true. Eventually, one must be carefull with the queue length. It is possible to set it to a minimal value, like 0.1 in order to be sure that only one file is loaded. However, when using an operator that buffers audio data in advance, like the crossfade, the new file may be ready too late. For instance, the crossfade sources buffer about 5 seconds of the end of each files. Hence, if the length is less than this value, the new file will not be ready quickly enough, leading to either the source being unavailable for a short time, or at least the crossfade transition being disabled.

There are several things you can do for that. First, you can use a partial application. For instance if you write: out.mp3 = output.icecast.mp3(stereo=true, restart=true, restart_delay=5, host=host0, port=port0, user=user0, password=passwd0, public=true, quality=0.2) The value out.mp3 is then a partial application, and you can use it to spawn several sources by passing it the missing arguments, for instance mount, name, description and source: out.mp3(mount=first,name=xx,description=yy,s) out.mp3(mount=second,name=xx,description=yys') If the repeated parameters are the same for each output.icecast.$codec, you can even write: def my_out(f) = f(stereo=true, restart=true, restart_delay=5, host=host0, port=port0, user=user0, password=passwd0, public=true) end And then: out.mp3 = my_out(output.icecast.mp3) out.vorbis = my_out(output.icecast.vorbis) out.aacp = my_out(output.icecast.aacplusenc) Hope that helps.

Yes, that is the default behaviour. I mean it seams to me that the playlist is already being streamed (somehow somewhere - i guess this is the way you have built it, read the playlist and start playing it) and the exact time i stop my live stream the playlist starts at the point it is. Is there any way to start the playlist from the beggining and not from the middle of some song? Should this have to do with length in the playlist command? Is there any way to achieve this thing (to start the streaming of the playlist from the beggining of it every time)? You can look at fallback.skip in the utils.liq file. This operators skips the file currently being played when changing source. Hopefully this will be sufficient for you. If you look for a real restart of the playlist at its beginning, this should need more work, but could be done too.

It looks intereasting. For my own education, can you explain what's actually happening? Thanks. Internaly in liquidsoap, we have a modular support for metadata. Each resolver registers itself to the main system, and when trying to find the metadata of a file, the decoders are tried one by one. Each of these decoders may return a list of elements of the form (label,value). Each elements of this list is added to the list of metadata. If there was another element with the same label, it is overriden with the new value. For instance, the replaygain resolver only returns a list with a single element, which is added to the list of metadata. add_metadata_resolver is the export of this system to the liquidsoap language. You can use it to register your own resolver. It needs to be a function of the form: string - (string*string) list In other word, this function takes a string, which is the URI of the (local) file, and returns a list of elements of the form (label,value).

[Savonet-users] Liquidsoap 0.9.1 is out !
Dear all,
The release 0.9.1 of liquidsoap is now available [1] !
We have received in the recent weeks a bug report about playlist reloading,
and while investigating on it, we discovered an issue is the code involved to
fill request-based sources, such as request.dynamic, request.queue/equeue and
playlist.
We believed this issue was important enough to trigger a bugfix release, so we
started preparing a new release incorporating the bugfixes we already had.
Along this path, we also included several features that we believed were
stable enough to be added.
In particular, we have also backported the changes on request-based sources
that allow to take into account the estimated remaining time when feeding the
queues. This allows a request-based source to prepare titles only when the
current one is about to end.
For the 0.9.1 release, the old behaviour is still the default, but the next
stable release will switch to the new behaviour. If you want to test the new
behaviour, you can set the following options on request-based sources in
0.9.1:
conservative = true
Other important changes such as the switch to ocaml-cry, our custom
implementation of the shout library, and the rewrite of external encoders will
have to be tested more before being released. These two features will allow
liquidsoap to natively support AAC+ codec when sending to icecast, using the
external aacplusenc binary encoder.
The full list of changes is given in the following changelog:
0.9.1 (18-06-2009)
Bugs fixed:
- Fixed request task not ending properly for request-driven sources
(playlist, request.queue, request.equeue). Fixes a problem reported
when reloading an empty playlist multiple times. (#269)
- Fixed math.h usage in rgb_c.c.
- Fixed append operator. (#284)
- Fixed OSS compilation for non-linux systems.
- Disconnect idle harbor sources after timeout has expired.
Thanks to Roman Savrulin for reporting and fixing !
- Taglib metadata resolver is only used on files decoded
by the MP3 decoder.
New:
- Get a node's striping status when stripping
blank with strip_blank (#260).
- on_connect function for input.harbor now receives the
list of headers given by the connected source (#266).
- Added on_end operator, to execute a handler when a track ends.
- Added estimated remaining time in the queue length for request-driven
sources (request.{equeue,queue}, playlist). This allows these sources
to prepare less files in advance. In particular, primary queue may
only contain the file currently played. Default behaviour has been
set to the old behaviour, and a conservative option has
been added to switch to the new behaviour. New behavivour
will be the default for the next release.
fixes #169, references #146
We will update our custom stable packages very soon, as well as the official
debian ubuntu packages. We also hope this release will be rock stable and
perfect for production.
Of course, if you encounter any issue when running this release, please report
it on our trac:
http://savonet.rastageeks.org
Or on IRC, or to this mailling list (but preferably to the trac system..).
Cheers,
Romain

You can override this value by adding to your script: set(request.max_id,100) However, we often assume that the current value is correct and that if you reach this limit there is probably something going wrong, either in liquidsoap or in your script.

I doesn't seem like a freeze. Apparently it switches to safe_blank, which is
the mksafe fallback I believe.
Could you send a similar bug with more verbosity:

Also, you can try to turn the conservative parameter to false for all sources
using playlist or request.{dynamic,queue,queue} and see if it helps.

You should use list.hd(get_process_lines()), get_process_output will have
the trailing \n at the end.
For debugging purpose, you can also print the retrieved URI before sending
the request:
def process () =

print(\n\n\nGot: #{s}\n\n\n)

All the servers were out of sync, so I made ntpdate on all the servers which were all 7000+ seconds later than correct time. Is it possible the timeout (today) and the too much latency were due to this synchro ? Yes, that is clearly the cause of the issue. Liquidsoap needs a time reference for checking that it is not late with respect to real time. Currently, this reference is the local time on the machine, which means that when changing it, you create an artificial delay for liquidsoap. We have discussed other implementations, but so far we believe that a server that goes out of sync with its local time is definitely a bad thing, since it will also mess with the other software in the streaming chain. Hence, it should be better to run regular ntpdate on the server. A small delay is ok with liquidsoap in this case.

File 1 start_next = 120, fade_out 120 File 2 (duration = 140), start_next = 50, fade out = 50 File 3 fade_in = 50 So 120 s before the end of file 1 we start playing file 2 and 90 seconds later we start playing file 3 but file 1 is not yet ended. There can indeed be some issues with the remaining time, in particular since this is an estimated value. However, the crossfade have a conservative option. Using this option, the data needed for the crossfade is buffered in advance at the beginning of each track. Did you try with this option ?

Re: [Savonet-users] periodic metadata rewriting
Le mercredi 08 juillet 2009 19:12:59, Gergely CZUCZY a écrit : Hello, Hi ! I'm back to this issue, now I'm facing the problem, I can't really get the stream I should be rewriting. Now I've got this piece of code: I think you're doing it the wrong way.. --- here --- -- function starts here def nextsong_cd(m) = # title=m[title] artist=m[artist] album=m[album] def insert_rnd(m1) = rnd=random.float(min=0.0, max=10.0) [(title, string_of(rnd)), (artist, string_of(rnd)), (album, string_of(rnd))] end cdradio = map_metadata(insert_rnd ,cdradio) system(/usr/local/bin/lstest.sh ^artist^!^album^!^title) end -- function ends here cdmdradio = on_track(nextsong_cd, cdradio) --- here --- Now, let's look at the the type of nextsong_cd: (string*string) list - unit This means that this function takes the metadata and does not return anything. In other words, this is a dead end function: it does whatever it wants and _voila_. However, you write, in the content of the function: cdradio = map_metadata(insert_rnd ,cdradio) When the function is executed, this line creates a source with random metadata. However, this source is not used anywhere after, so it is just cleared away when the function has finished.. The correct way would be to apply both function on the same source, but in the right order, of course :) This gives: --- here --- # This functions records the passed metadata def nextsong_cd(m) = # Get the variables title=m[title] artist=m[artist] album=m[album] # Call the script system(/usr/local/bin/lstest.sh ^artist^!^album^!^title) end # We call the above function on each metadata cdradio = on_track(nextsong_cd, cdradio) # This function replaces all metadata with random values. def insert_rnd(_) = rnd=random.float(min=0.0, max=10.0) [(title, string_of(rnd)), (artist, string_of(rnd)), (album, string_of(rnd))] end # Apply this function, set update to false to discard remaining entries cdradio = map_metadata(update=false, insert_rnd ,cdradio) --- here --- Now, the problem that you will have is about after a few frames put back the original metadata.. I don't have a magic solution for that. You could combine the use of insert_metadata and add_timeout. When receiving the metadata, in the nextsong_cd function, you could use add_timeout to rewrite the correct balues back after some time. However, I don't know what's the good some time..

Re: [Savonet-users] Fedora RPM Building
Hi ! Le lundi 27 juillet 2009 22:29:12, Chris Everest a écrit : So i started looking into building a Fedora RPM of liquidsoap. Thanks for this work, this is a great news ! I keep finding myself compiling (yuk) and have even resorted to running virtual Ubuntu instances, to make the liquidsoap install less painful. So here's my question: 1.) Do I need to split out lame dependencies (et al non-free library dependencies) to have this RPM distributed by the liquidsoap project? Clearly no. The stable and daily build packages are built directly from the full set of dependencies without individual packages. The problem can be for external dependencies like ocaml-pcre if they are not packaged for Fedora. In any way, you can distribute a binary package of liquidsoap without the need to also package the external dependencies that we ship. 2.) Maybe Axel from atrpms would dist? Or rpm fusion. I don't know how those orgs operate. I don't know. For reaching the most users as possible, it is always better to distribute the packages there and not in the project's website. I don't know how these sites work, though. In particular, you'd probably have to also package the dependencies in this case.

Re: [Savonet-users] Get current song
Hi all ! The two solutions mentioned by Bede are valid. I even believe we use the first one for dolebrai. Additionally, you can also use the on_metadata operator. This operator will call a function that you specifiy, which can be in particular a call to an external script, when it see new metadata. That way, you can register the latest metada in a database, for instance, and use it on the other computer in order to retreive the current song.

I installed all libraries what we need to run liquidsoup except ocaml-xml-light. Try this way- I installed but it's something wrong, but I really dont know. Yes, that's a well-known issue. The problem is that we had chosed ocaml-findlib to detect xml-light. However, we realized later that in fact, the support for ocaml-findlib in xml-light was a debian-specific patch.. Unfortunately also, xml-light is no longer maintained so there will be no release adding that support.. For the current developpement code, we have switched to xmlm which has a ocaml-findlib support and is maintained at the moment.

Re: [Savonet-users] Playing blank
Le vendredi 4 septembre 2009 02:28:05, vous avez écrit : Yes I used it in the previous version except the metadata change function. But in this time we stopped the radio every days (at 5 AM). Now the radios are playing for days. Moreover we were in a beta stage at this time (with some other problems due to our infra) so I'm not able to say if this specific problem was already present. Ok, thanks. I am considering either a bug in the scheduler, or a bug in the requests system. What you can do to check this is to allow a telnet server for each instance. A simple (and probably a bit hacky) way to do that could be to set the telnet port to the pid of the running liquidsoap: set(server.telnet.port,getpid()) set(server.telnet,true)' (Probably better at the end of the script) Otherwise, you can also pass the port as a parameter as you do for the other parameters. Then, as soon as an instance goes to blank, it would be interesting to try to connect to its telnet and issue some dummy commands. Simply connecting to telnet, if sucessful, shoud indicate that the scheduler is not the issue and then we could concentrate on the request system. Later on, if you need some work-around, in case the issue is not the scheduler, we should be able to provide you with a patch that allows to manually restart the failed queue.

Re: [Savonet-users] [Savonet] #303: Large tracks take long to load
Hi ! Le mercredi 9 septembre 2009 17:48:58, vous avez écrit : What I was hoping to see: Start your liquidsoap with a playlist designed to fit x # of hours. Put in a variable assuming that the first track is the track I want to play next (obviously common sense in every situation of listing things in a fresh manner of speaking), when the playlist has reloaded (and detected as a NEW playlist ie: ANYTHING changed... Size, Shape, Order, whatever I don't think it matters) ie: changes made to the playlist, but while starting at the top of the playlist after the track that is playing has finished. This would allow us to create day long playlists, and then updating the new playlist in the evening, rather than do substring cutting, and searching through a playlist file to see what has been playing. Thanks! Sorry if I sound like I'm complaining, this stuff is kind of difficult if you just learned linux a week ago :) No problem, you're much welcome ! However, please try to use the mail adress dedicated to user's support, which is: savonet-users@lists.sourceforge.net About your issue, my guess is that your needs will not fit the playlist design. The playlist in liquidsoap is really designed to be something flexible, where you put a bunch of songs to be played. If you need a more precise control over what you play, the best would be to have liquidsoap call an external script. Such a source can be created using the request.dynamic operator. Using this operator, each time liquidsoap needs to queue a new song, it will call any script that you provide it and use the returned value. That way, you can work out all your constraints outside of liquidsoap, using your prefered language etc.. All you need to do it to code a script that returns the new song to queue. A usage example would be: # Request function def request () = request.create(audio=true, list.hd(get_process_lines(/path/to/script)) end # The dynamic source: s = request.dynamic(request) The first part of the code is a function that calls the script /path/to/script and creates a new request using the the first line of its output. The second part is a source that calls the function request in order to get its new songs. Please don't hesitate to ask for more details if you need !

What do I name my script file? What do I put in it? Do I need to do a Single, and echo back something? Can you help. Well the script should be some sort of program of your own, all liquidsoap requires is that it writes to its standard output the name of the next song to queue. Then you can put all the details you need on this script. The dummy example to start with could be: 8--8 #/bin/sh # Dummy script that always returns the same song... echo /home/nocturnal/tunes/_TODAY/10.today.mp3 8--8 You save this content to a file, say /tmp/test.sh and then do: chmod +x /tmp/test.sh which will make it executable. Then on the previous code example I gave you, you replace /path/to/script by /tmp/test.sh. However, this is a stupid script, in order to have the scheduling you need you will need to write your custom script that returns exactly the song you want to play. The advantage of this method is that you are free to use whatever language you feel comfortable with, and you will not have to cope with the details about playlists in liquidsoap. Hope this helps..

Now I have two of the same track ready to play (...).. I just need to know how to tell Liquidsoap what to load. I don't know SH programming, I'm actually a pure PHP programmer. Ok, please apologize for my previous assumption then... But it's a real mystery here what your software wants to receive, and how it should be received. It's been a guessing game. The thing is that liquidsoap wants to keep in advance a queue of some requests in order to make sure that it will always have something to play. Hence the two songs that you see on the initial startup. Provided you have liquidsoap 0.9.1, you can however, use the new behaviour which will allow only one song to be requested at once. What you need is to do: request.dynamic(conservative=false, length=5., (...) That way, liquidsoap will estimate the length of the current song and only query for a new one when there are 5 (estimated) seconds remaining. The reason for this being an estimation is because mp3 format, for instance, does not allow a reliable length computation, hence computing the total length needs the decoding of the whole song, which we want to avoid :) Once I can dynamically talk to liquidsoap using the request.create (without every request being a duplicate, and without liquidsoap needing a new fallback to facilitate it during this dynamic method), I'll add a fallback playlist later. Right now I'm focusing on how to have full control over liquidsoap using request.dynamic, so I can begin writing a scheduler in PHP. Ok. I hope that with the above settings, you should have the full control of the scheduling in liquidsoap.

Re: [Savonet-users] Metadata-based on/off switch for smart crossfading
Le dimanche 20 septembre 2009 10:30:07, David Baelde a écrit :
Hi,
Hi !
The smart_cross() operator takes a transition function of type (float,
float, [(string*string)], [(string*string)], source, source)-source).
This means that it is of the form fun (v1,v2,m1,m2,s1,s2) - ... where
v1/v2 are the volumes before/after the track change, m1/m2 the
metadata before/after the track change, and s1/s2 the source
before/after the change.
So, you can read the metadata attached to the next track using for
example m2[cross]==no.
Just to add more details. If you want an example of the use of a function for
smart_cross, you can look for the definition of smart_crossfading in utils.liq.
Now, if you want a metadata to prevent any transition, you could do:
def smart_crossfade (~start_next=5.,~fade_in=3.,~fade_out=3.,
~default=(fun (a,b) - sequence([a, b])),
~high=-15., ~medium=-32., ~margin=4.,
~width=2.,~conservative=false,s)
fade.out = fade.out(type=sin,duration=fade_out)
fade.in = fade.in(type=sin,duration=fade_in)
add = fun (a,b) - add(normalize=false,[b, a])
log = log(label=smart_crossfade)
def transition(a,b,ma,mb,sa,sb)
list.iter(fun(x)- log(level=4,Before: #{x}),ma)
list.iter(fun(x)- log(level=4,After : #{x}),mb)
if mb[cross]==no #
# no transitions#
then #
sequence([a, b]) #
elsif
# If A and B are not too loud and close, fully cross-fade them.
a = medium and b = medium and abs(a - b) = margin
then
log(Old = medium, new = medium and |old-new| = margin.)
log(Old and new source are not too loud and close.)
log(Transition: crossed, fade-in, fade-out.)
add(fade.out(sa),fade.in(sb))
elsif
# If B is significantly louder than A, only fade-out A.
# We don't want to fade almost silent things, ask for medium.
b = a + margin and a = medium and b = high
then
log(new = old + margin, old = medium and new = high.)
log(New source is significantly louder than old one.)
log(Transition: crossed, fade-out.)
add(fade.out(sa),sb)
elsif
# Opposite as the previous one.
a = b + margin and b = medium and a = high
then
log(old = new + margin, new = medium and old = high)
log(Old source is significantly louder than new one.)
log(Transition: crossed, fade-in.)
add(sa,fade.in(sb))
elsif
# Do not fade if it's already very low.
b = a + margin and a = medium and b = high
then
log(new = old + margin, old = medium and new = high.)
log(Do not fade if it's already very low.)
log(Transition: crossed, no fade.)
add(sa,sb)
# What to do with a loud end and a quiet beginning ?
# A good idea is to use a jingle to separate the two tracks,
# but that's another story.
else
# Otherwise, A and B are just too loud to overlap nicely,
# or the difference between them is too large and overlapping would
# completely mask one of them.
log(No transition: using default.)
default(sa, sb)

Re: [Savonet-users] What are the laws?
Hi all ! Le jeudi 24 septembre 2009 09:36:23, Gilles PIETRI a écrit : I've been reading for hours and I think Im more confused than ever. Does anyone have any experience with licensing? Anyone know if/how the laws apply to mixes and live broadcasts as opposed to singles playing? In France, no matter what you broadcast (remixes, bootlegs, live shows..), you have to get an agreement with several of the rightholders defenders.. That is the SACEM, SCPP, SCPF so on.. Even if you play unlicenced (or licenced but on other terms than theirs) music, there is some case you still have to pay a fee.. Which is rather irritating obviously.. And it's not cheap also ;) Hmmm. Do you also mean it for Creative Commons licensed music ? About the MP3 format, which was in the initial question, this depends. The basics of the license for using mp3 is the patents over the corresponding audio technologies. However, such patents are not filed worldwide but localy, one for the USA, one for Europe etc.. So if there is no patent in your country (say... Russia ?), then you don't have to pay a license. Furthermore, some countries, like the countries in European Union do not recognize software patent (to some extend), hence it is highly possible that such license fees would be illegal. (to be confirmed) In any way, one of the main purpose of the ogg codecs was precisely to have patent free technologies. So if you stream using one of the ogg codecs, say ogg/vorbis, you do not have to pay fees, and will never have. This fact, by the way, really makes me wonder why hardware manufacturers still push for patent-encumbered technologies, which is exactly like shooting its own foot where they could use patent-free technologies and save costs.. As for mixes or bootlegs, there are even artists who refuses them, in case you might alter how good their music sounds.. Hmmm... But I am not sure this is legal for the artist. So far, my understanding is that, in France, as soon as you pay the required fees you have the right to broadcast the artist's performance. This is probably linked to the legal requirement that an artist cannot cancel a publicaly exposed artistic thing. Most similar to the fact that they can't refuse a cover of their song, can they ? In particular, I remember that radio show on sunday on Skyrock when I was a teen that was playing bootleg lives for a couple of hours and was, I believe, totaly legal. Romain -- Come build with us!

Its been working very well so far :-) However, here are some things Id like to see in a future release: Thanks for your encouragements ! 1) Better video support. I want to be able to broadcast video from DJs while they play live or from remote locations like clubs and parties. As it is right now, I will likely just use a 3rd party flash video streaming application but it will not be fully synced to the music. Idealy the best way is to do it all together in liquidsoap. Sure ! Video support is already an ongoing work. Current status is however half-baked and there are core changes that are waiting to be done. We are currently working on this, but this will be for liquidsoap 1.0, which will eventually land, but not in the short term. We will inform you and the other users as soon as we have something ready to be tested for production ! 2) Better support for external input and/or porting between programs. I am planning on setting up a web-based telephone switching board so listeners can call in a toll-free number to get on the radio. The DJ will be able to view the virtual switch board online and control who goes on air, view whose waiting, bridge them all in, just one, cut people off..etc. I can do this all through Asterisk (Open source PBX program), but I have no idea how to port this audio into liquidsoap...especially during a live broadcast. Maybe some way to merge a harbor input and an input.external? This should be feasible with an input.external. What you need is a program that is able to receive the calls and output the sound to its standard output in a pcm format. Then you should be able to have a new source using input.external and this program to acheive what you want. I remember that at least one user tried this recently. Romain -- Come build with us!

Re: [Savonet-users] Read error Unix.Unix_error(56, read, ) ???
Hi Gabriel ! Le dimanche 20 septembre 2009 21:20:08, Gabriel Afana a écrit : So today I had something unusual happen for the first time. A DJ was playing live (input.harbor) and about 40 minutes into his show, liquidsoap fell back to the playlist and continued playing the normal playlist that plays when there isn't a live show. The really strange part is I checked to logs thinking to see the DJ simply lost his connection, however this wasn't the case. The logs showed that he reconnected again and my on_connect and on_disconnect function logs show that he did connect again but never disconnected (i.e. he was still streaming). However liquidsoap was still playing playlist songs and wasn't going to the input.harbor source. This has never happened before. I had to go in and manually run the on_disconnect function since it never ran. I have a crontab running every minute that checks and disconnects the DJ the minute his timewinow is up (using telnet connection). Even if all else fails, this will disconnect his input.harbor connection and of course should run the on_disconnect function. The crontab ran and connected via telnet but the on_disconnect function never ran (leading me to believe he was never connected anyways because the radio was streaming the playlist and not his live show). However, he connected but never disconnected (but was no longer connected!!) haha confusing! I noticed an unusual error i've never seen. Maybe this is what caused this strange occurance? Ok, I am looking at your issue now. From what I see on the log, it seems like everything hapened has expected. The exception you saw on the log is generated because the reading on the socket failed, and as expected you see that the harbor source disconnects him. Then, the second request that you see on the logs is in fact a metadata update request. It means that the source client tried to do a metadata update request, which will suceed even if the audio feeding has failed. The thing that I don't see in the logs is the second source client connection on the harbor. Perhaps it should need to look later in the logs ? So, my understanding is: * The connection with the DJ was lost at some point * The behaviour after that was not what you expected Hence, as such I cannot reallt judge whether the problem after the deconnection comes from the source client (VirtualDJ) or from liquidsoap. It would be nice if you could send us more logs, in particular a bit before and after the issue so that we can see the harbor source client connections. Romain -- Come build with us!

I even tried using an aacplus stream for http.input, and I was surprised that worked.

Still I'm looking forward to useing aacplus and will drop certain streams in favor of it. Thanks for the report ! The aacplus encoder is known to have issues with parametric stereo, which is used at low bitrates, such as 32k. So far, it performs quite good at 64k, which I would recommend for now. The nero AAC+ encoder has a much better quality at each bitrate. However, it is not yet possible to use it as an external encoder. I have requested the changes upstream, they say they will surely consider it, so we have to wait and see.. Romain -- Come build with us!

Re: [Savonet-users] log rotation

Hi!
Hi !
Can i use logrotate tool to rotate liquisoap log, or it has internal
capabilities to do this stuff?
Yes you can ! :-)
The basic logrotate script provided by liquidsoap is:
/var/log/liquidsoap/*.log {
compress
rotate 5
size 300k
missingok
notifempty
sharedscripts
postrotate
for liq in /var/run/liquidsoap/*.pid ; do
if test $liq != '/var/run/liquidsoap/*.pid' ; then
start-stop-daemon --stop --signal USR1 --quiet --pidfile $liq
fi
done
endscript
}
As you can see, you need to send the USR1 signal to liquidsoap after moving
the file away..

Re: [Savonet-users] Fading / Silence issues after version 0.3.8.1
Le mardi 29 septembre 2009 03:34:28, Frits Letteboer - St. Radio Twenterand a écrit : Hi there, Hi ! After checking out the latest SVN version there seems to be some issues between regular tracks. In the old version there's a smooth crossfade between regular tracks. In later / the latest version(s) this has changed to fade out - 10 seconds of silence - fade in to next song. The fades from/to jingles and commercials still work as expected. I'm pretty sure I screwed up somewhere, but I can't find where. So I've attached the script used in both cases. Thanks for the report ! There can be various possible reasons for your issue. The first and immediate that comes to my mind is the change in the default behaviour of request-based sources. Now, the new song request is triggered only 10 seconds before the previous song ends. So if the requests and song processing takes too long, you might experience this kind of issues. What you can do to test this assumption, is to pass the option conservative=true to request.dynamic, but also playlist if needed. Please let us know whether it helps, otherwise we would try to find another reason for your issue. Romain -- Come build with us!

Re: [Savonet-users] Considering shutting down my radio and possibly making my radio management system public
Hi Gabriel ! Le mardi 29 septembre 2009 21:35:14, Gabriel Afana a écrit : So I've been doing a LOT of research in the legality of running an internet radio and because of all the corrupt politians (at least in the USA), running a legal internet radio station is not really possible for most people due to the OUTRAGEOUS fees of SoundExchange. I've looked into running the radio in another country such as Canada which have less strict laws, but the radio is for an online community I run which is a legitimate business that I make my living off of. I dont want to merge shady business activies (such as moving the radio system to canada to avoid fees) with my legitimate business and have possible problems down the radio. Im REALLY upset about this because I spent the last several months developing this radio (spending 10-12 hours/day working on it). This is what I was doing full-time. I am really sorry to hear this. I understand why you want to do your business seriously and why you do not want to use alternative sneaky ways. I personaly believe the actual fees for net broadcasting are decided while consulting only the existing players, which already have a lot more income, and also for the most of them rely massively on traditional broadcasting, and for that reason do not have any interest into letting new concurrent appear on internet... I really hope that people like you with innovative ideas and willing to work full time on setting up new broadcasting systems for internet find their own economic equilibrium. However, if I end up shutting down my radio, I do not want all that work of mine to go to waste so I would like to share it with you guys. If this ends up happening, I'll be sure to give everyone a tour and explain how it works. In the very unfortunate case where this would happen, we would be pleased to host the source code, provided it is released under any open-source compatible license, which I am sure is what you have in mind. Another issue from our perpective would be the maintenance of the code, but that is another topic. Romain -- Come build with us!

Since delay is working flawlessly with that version and works great for queueing promotions and commercials. Could you also check whether the bug disapear when you remove the delays, please ? If I removed the delays I would be listening to commercials and jingles all the time? I will check this and report back. Hmm Sorry, it seems I have confused delay and lag..
