Hi,

a happy new year!

Mostly we stream stereo but sometimes some sources are mono.
In the past we got Incorrect stream type! and fails, but then there was the 
audio_to_stereo invention.
I upgraded to latest hg and tried to switch from a stereo to a mono stream by 
using the audio_to_stereo operation applied to all sources.
Unfortunately this does not help and fallback is played as without 
audio_to_stereo.
Error messages is same as without audio_to_stereo: Incorrect stream type!

Do you have any idea?

Re: [Savonet-users] Rotating Archives

Hi, try this one:

I guess you are talking about audio archives and not about log archives...

output.file(
 %wav(stereo=true),
 /mnt/archive/raw/%Y-%m-%d/%Y-%m-%d-%H_%M_%S.wav,
 on_close=fun(s)-system(qwavheaderdump -F #{s}),
 reopen_when={0m0s},
 mksafe(radio)
)

this will hourly save a new audio archive file.

You need to install quelcom package to use qwavheaderdump (in case of any 
process stops, wav header will be correct)
You can remove on_close line, if you do not use it.
You could use other reopen_when intervals ({0m0s} is hourly, {0h0m0s} is daily.)
You can use other file directory and filenaming.

please see output.file docu for mor details
http://savonet.sourceforge.net/doc-svn/reference.html#output_file

 Hi,

 Do you mean an audio archive?

 At the moment, I'm trying to settle this in my project.

 I'm already able to transcode-record my stream in a local file and it
 works very well(24 Kb/s, 16 Khz, mono to save disk space).

 Now, I've planned to experiment on using unix logrotate utility to
 store daily a new time stamped archive, but not tested yet.
 This should work without needing to kill or restart the output stream
 and should be totally automated rotating on a monthly basis.

 Does this correspond to your needs?

Re: [Savonet-users] Incorrect stream type! on mono streams w/wo audio_to_stereo

Hi,

thanks for your fast answer.

In general I switch between several source streams, but do not know if they are 
mono or stereo.
As I understand the source() of your example this would handle all streams s as 
mono -
would this work even for stereo streams?

  Thus, you need to force the type to a mono stream this way:
  # Mono input.http
  s = (input.http(http://radiopi.org:8080/reggae;):source(1,0,0))

 Yes, there is a glitch that we need to document more: default source

 The restart argument was super seeded by a new on_error callback.
 This callback is executed every time an error occurs. It receives a
 string representation of the error that occurred and returns a float.
 If this float is positive, connection will be tried again after its
 value, in seconds. Otherwise, connection is not retried.

 Default callback is: fun (_) -  3., that is: restart after 3 seconds.

 Hi,

 The HTTP input has a url command that returns the current URL, or
 sets a new one if an URL is passed as argument. In the previous
 example, that would be live.url http://etc;.

 A combined command can be created from the following function:

 def start_live(url)
server.execute(live.url #{url})
server.execute(live.start)
 end

 If you want to use that command to change the URL of a HTTP input
 _while it is running_ you should execute live.stop before restarting
 it: otherwise it'll keep running with the old URL.

 Cheers,

We are using this feature intensively to switch between several radio stations.
 From my experience you should additionally wait some time (seconds)
  between stopping the old and starting the new stream.
If you start before the old one has really stopped, the old URL sometimes will 
be played again.

Re: [Savonet-users] New domain liquidsoap.fm and new flows services!

2011-11-28 Thread Peter Retep

Hi Romain,

thanks for update!
I have not sent any requests to the list during last time since liquidsoap ist 
still doing a
perfect 24/7 job for years at our radio network.

We are running mostly live content from the studios, so there are no metatags 
in the streams at all.
Title, URL, location and description of the current broadcast is given by an 
external calendar.
Additionally we have currently 4 geographically distributed locations we stream 
from, but we are sharing FM online time (only one station is online at FM 
transmitter at the same time).
Since we have had problems at the decoder side
  - using OGG CBR streams and
  - metadata updates from the calendar at the same time,
we finally disabled flows for stream stability reasons in live mode.

To re-join the flows network again I could create a separate liquidsoap instance
with flows enabled which just inserts the currently sending station's metadata 
to an empty stream,
but this seems resource overkill to me.

Is there a more simple way to just push the current metadata from the calendar 
directly to flows?
I can get the current broadcast title, URL and location from the calendar 
without any problem.
(Today we also push the current broadcast to twitter so this could be easily 
adopted to push to flows protocol additionally).

Thanks in advance!

Peter

Am 09.10.2011 22:21, schrieb David Baelde:
 Dear all,

 After several beta versions, a release candidate and lots of local
 tests... Samuel, Romain and I are proud to announce the release of
 liquidsoap 1.0.0!

 Although many people already use liquidsoap in various production
 settings, this is an important milestone for the project. We consider
 this version stable and well designed, we'll maintain it as it is,
 doing our best to ensure backward compatibility.

 Of course, we also already have several important ideas for the
 future, but we'll take a break before starting to move towards 2.0 ;)

 As usual, download from our sourceforge page:
http://sourceforge.net/projects/savonet/

 We hope you'll enjoy it. Don't hesitate to spread the word, and don't
 forget to register into the Flows which is absurdly Franco-French
 at the moment (http://savonet.sourceforge.net/flows.html).

 ** Background

 Liquidsoap is a programming language for multimedia stream processing,
 mainly used in building complex netradios. This design makes it a
 flexible tool: we believe that liquidsoap is easy to get started with
 for a simple project, but the programmability and the many features
 make it possible to extend your system beyond what any other tool can
 do in that domain.

 ** History  Credits

 Not counting a demo in 2004 at ENS Lyon, Liquidsoap's first release
 was the 0.2.0 in 2005. The 0.3.0 line brought the first stable
 versions, used in productions with uptimes of months. In 2009, we
 started the 0.9.0 line, determined to bring what we considered to be
 the missing features for 1.0.0: per-source stream types (mono in one
 source, stereo in the other, video in yet another) and clocks. The
 first 1.0.0 beta version came up in Sept 2010, and we've mostly been
 stabilizing since then -- although a few important features were also
 introduced, notably the seek support, v4l input, minimal HTTP
 icecast server capabilities, OSC support.

 Liquidsoap's main developers are David Baelde, Romain Beauxis and
 Samuel Mimram. But the project has benefited from the contributions of
 many more people, including Vincent Tabard, Julien Cristau, Stéphane
 Gimenez, and many more from year when liquidsoap was a students'
 project at ENS Lyon. We'd also like to thank the many people hacking
 liquidsoap scripts, building tools on top of it, who bring valuable
 feedback and ideas.

 ** Changelog

 This is the changelog for 1.0.0 only. If you're migrating from a
 version of liquidsoap older than the beta3, don't forget to check the
 full CHANGES file for migration tips!

 1.0.0 (08-10-2011)
 ==
 Finally, the 1.0.0 release! It brings several important fixes, but
 also some nice novelties.
 The most outstanding difference concerns output.icecast(): its restart
 and restart_delay parameters are gone, replaced by a new on_stop handler
 which is called on every error (failed connection or disconnection) and
 returns the new restart delay. The on_error handler receives a string
 describing the error which enables user-friendly reporting, adaptative
 delays, etc.
 Note that on_error defaults to fun(_)-3. which is equivalent to having
 restart=true, restart_delay=3. in previous versions, NOT the same as the
 former restart=false default. As a result, liquidsoap won't fail to startup
 if an initial connection attempt fails.
 ==
 Fixes:
 - LS-532,527: avoid freeze after errors in streaming threads or source
initialization routines
 - LS-542: race condition in playlist*() breaking randomness
 - LS-489: double expiration lead to illegal queue length and freeze of
request-based sources
 - Avoid multiple simultaneous reloading in playlist*(),
thanks to Fabio Costa for his help on this one!
 - Pass charset information to icecast server to avoid encoding bugs
 - LS-555: timeout for icecast connection attempts
 - LS-559: permanent stop after disconnection on Ogg streams
 - LS-565: efficient and crash-free error handling in input.http/harbor()
when the input stream has an invalid number of channels
 - LS-431: proper handling of duration in blank() avoids abusive empty tracks
 - LS-556: rework conversion operators, optimizations used to be unsafe  
 broken
 - LS-574: silent MIDI synthesis operators
 - LS-396: drop*()'s types reflect that they don't support variable arities
 - LS-442: allow comments not terminated by newline at end of file
 New:
 - on_error handler in output.icecast(), see above
 - New msg param in %mp3 for marking frame headers, defaults to version string
 - output.file(): new on_close parameter, may be used to write exact duration
 - %mp3.vbr/abr for variable bitrate MP3, %mp3 is now a synonym of %mp3.cbr
 - MP3 encoders now support ID3v2 tags
 - input.http(): new status command
 - LS-556

2011-10-03 Thread Peter Retep

Hi

  This one is a recurrent one.. Other user (Peter) reported that the

  problem went away by starting from scratch with a proper ./bootstrap


It think the deinstall/install of all soundtouch libs could have beed important.
Since this behaviour did only occur sometimes in the past, it could be related 
to update installation (or if any older soundtouch lib is installed) only.
I remember some threads on this a long time ago.

 Is Peter sure to have soundtouch activated?

Peter is sure:

  liquidsoap --list-plugins | grep soundtouch
  + soundtouch

For more convinience there could be a additional status line for doc generation

 Hi,
 Hi Peter!

 Switching the savonet homepage to web 2.0 by using jquery's show/hide 
 feature makes the site comfortable to use.
 Unfortunately deep links using #anchors do not work anymore everywhere .

 in case you are bored by fixing sound related errors I have some ideas on 
 this:

 For instance lets take the reference page: 
 http://savonet.sourceforge.net/doc-1.0.0-beta3/reference.html

 There are sections like source/output and elements like output.file.

 If one wants to reference one of both items, (as I tried to do in my last 
 mail to Josh)
 one could do this by using section/element anchors:
 http://savonet.sourceforge.net/doc-1.0.0-beta3/reference.html#SourceOutput
 http://savonet.sourceforge.net/doc-1.0.0-beta3/reference.html#output_file

 For users without javascript it would be helpful
   - to put aa name=output_file  before the links of sections and 
 elements.
   - to put the link href to this anchor. In this case the link href could be 
 set to #output_file.
 This enables browsers to jump to the right section/element when loading a 
 page, referenced like above.

 For users with javascript enabled, following code could be used to
 show all sections or elements that are addressed in the URLwhen the page 
 gets loaded :

  $(document).ready(function() {
  var parts=document.URL.split(#);
  if (parts.length1){
  var id=#+parts[1];
  $(id).parent().parent().show();
  $(id).siblings().show();
  }
  });

 This was working already today for elements, since they provide a id already 
 (like #output_file),
 It could work even for sections, but sections have no id today (like 
 #SourceOutput).

 These changes would make the sections and elements linkable with both web 
 1.0 and 2.0.

 A more generic and efficient way would be, to provide for both items 
 (sections and elements)
   - an anchor with the name of the link target
   - a link targeting this anchor
   - the content div which contains the id used to show/hide this element.

 example
 li
 !-- provide a section anchor --
 a name=SourceOutput /

 !-- set link target to section anchor --
 a href=#SourceOutputSource / Output/a

 !-- have an id at the content to show/hide the content --
 ul id=#SourceOutput class=liq-api-sec style=display: none;

 li class=liq-api-elem
 !-- provide a anchor --
 a base=output_file /

 !-- move id to content div, set link target to output_file --
 a href=#output_fileoutput.file/a

 !-- have an id at the content to show/hide the content --
 div id=output_file class=liq-api-content style=display: none;
 pre(?id:string,?append:bool,?dir_perm:int,?fallible:bool,.../pre
  ...
 /div
 /li
  ...
 /ul
 /li

 With help of this changes you could do directly
  $(id).show();
 instead of
  $(id).siblings().show();

 if id, anchor, and link target contain the same value,
 you could use the link target (href) to address the content div id, which is 
 to be shown/hidden.

 anyway, the page works good as it is.
 Thanks for all those suggestions! I have juste commited an
 implementation of it!!

 This is fixed now..

 2)
 documentation cannot be generated if libxml-dom-perl is not installed.
 Currently there is no info about this at the summary after configure.

 Instead there are following lines. I wish at least a WARN hint to allow grep
 for WARNings or ERRORs:

 Converting content/video-static.txt to html/video-static.html...
 -  You don't seem to have perl XML::DOM module installed.
 -  Language reference cannot be generated.

 For more convinience there could be a additional status line for doc
 generation at end of configure...
 You're right about this, we could make it more visible that this
 module is missing..

Re: [Savonet-users] using pulseaudio mix as input

Hi Romain,

Thanks for your input!

I totally agree, using a filesystem allows a lot of flexibility with a range
from using mounted external storages up to using distributed web storages (like
wuala, dropbox, etc) or any other virtual mapping.

Back to the topic itself: I made it using pacmd from pulseaudio-utils. paman
showed me the way to this.

example without soundcard:

pacmd list-sources | grep name:
name: auto_null.monitor

liquidsoap 'output.file(%mp3, /tmp/test.mp3
,input.pulseaudio(device=auto_null.monitor) )'

example with soundcard:

pacmd list-sources | grep name:
name:
alsa_output.usb-M_Audio_USB_Audio_Quattro-00-Quattro.analog-stereo.monitor

liquidsoap 'output.file(%mp3, /tmp/test.mp3
,input.pulseaudio(alsa_output.usb-M_Audio_USB_Audio_Quattro-00-Quattro.analog-stereo.monitor)
)'

the mp3.file contains everything that was played by vlc during the recording
time.
So basically this seems to work (I have made no extended tests up to now).

Good to know that you can just plug in any sound source to liquidsoap by still
using pulseaudio monitors!
Once more this shows to me the advantage of unix philosophy and of providing
generic interfaces! Thanks for supporting this!

Hi all !

I like the idea of a file system -- file systems and file hierarchy
always seem more intuitive to people..

One idea tho: what about actually running a _virtual_ file system
using fuse? You could then map a database and any kind of storage to a
fuse-based filesystem. User drops a file, DB is updated and file moved
to storage.. Also, all directories are created at once and the
structure can be constrained to only have valid path and perhaps files
etc..

Finally, you can easily map this to another view, for instance a web site..

BTW, concerning pulse devices, I think you can use pulse's tools such
as paman and the like..

2011/9/27 Peter Reteppeter_re...@gmx.de:
Hi Damien,

If a user does not follow the convention, his/her files will not be played.

Usually all shows are planned some weeks or days before. We use a google
calendar for planning this.
The calendar synchronisation creates all directories from this and
additionally creates the website entries with all show descriptions.
So mostly user dont need to create any directories, since this is
automatically done if the show is scheduled at the calendar.
So user just needs to drop its mp3 file into the right directory. If there
is a urgent need (e.g. someone has forgotten to schedule the show)
he sees all existing directories and can use them as template for the path
convention. User does not even has to take care of the file name or any
metatags
(except correct audio duration metadata).
The scheduler writes frequently current and next show to log. So you can
check for errors, before the scheduler (or a cron job) would try to start a
non-existing file.
Additionally I do not want to need the user to care about correct file paths
in the jobs.
All of this should help to prevent misconfiguration or user errors.

There are multiple reasons why I do not to use a cron job for this:

- Most users I know, do not know even what a cron job is or what faults you
can do when writing one.
Additionally I would not like a separate cron job for each show (imagine
24 shows a day, 365 days a year, ok, today we have only around 10
preproduced shows a week).

- If there are any changes needed, the user just needs to update the file
system.
So there is no database or any other redundant definition (like cron) of
what is to be played when.

- Furthermore the scheduler checks frequently if the current show player
is running.
If not, the start of the show will be cutted and played from the
current position.
This is useful for reboots due to power outages and other outages like
process failures. The scheduler would be respawned by upstart on failure.
Another case like this: the user puts the file at the right directory
still one minute after the show should have been started (many users I deal
with deliver their productions at the last minute .-)

As you can see the scheduler does a lot more than still starting a file at a
certain time (e.g. logging, process audits, house keeping, etc.) to keep
everything running

Re: [Savonet-users] installation: required repositories/packages to build from HG (aac, aac+, soundtouch)

Hi Romain,

I retested with cleaning make, deinstall and install soundtouch libs and then 
it worked.
I am not sure in which situations it is necessary to remove/install soundtouch, 
I have seen this seldomly on several systems.
Sometimes I need to reinstall these libs before installation and sometimes it 
works without doing so.
Maybe it is enough to put this seldom case to the installation hints.

sudo make clean
sudo apt-get remove libsoundtouch*
sudo apt-get install libsoundtouch*
./configure
make
sudo make install

BR, Peter

PS: I am just wondering why I need to call make clean with super user rights.
Some files cannot be removed if I call it with the same user as I make it.
Are there some files created with super user at the source directories , when 
calling make install?

 That could work indeed.

 Installation without soundtouch worked if I removed all existing soundtouch

 I did not get it working with using soundtouch in the PACKAGES file.
 Since I do not need this, it is big no issue, I just remember I had the same

Hi Josh,

output.file( %mp3(bitrate=160), /tmp/%Y-%m-%d-%H_%M_%S.mp3, 
reopen_when={0m0s}, radio)

consists of:

%mp3(bitrate=160)

the encoder (mp3) and its options (mono/stereo, bitrate, frequency...)


reopen_when={0m0s}

creates a new file every hour (minute=00, second=00)


/tmp/%Y-%m-%d-%H_%M_%S.mp3

the output path/file pattern, containing the date and time when starting to 
record a file.
%Y is current year
%m is current month
%d is current day
%H is current hour
%M is current minute
%S is current seconds

this would create a file /tmp/2011-10-01_19-10.mp3 at

You can adopt this pattern to your needs.

[Savonet-users] web doc proposals

Hi,

Switching the savonet homepage to web 2.0 by using jquery's show/hide feature 
makes the site comfortable to use.
Unfortunately deep links using #anchors do not work anymore everywhere .

in case you are bored by fixing sound related errors I have some ideas on this:

For instance lets take the reference page: 
http://savonet.sourceforge.net/doc-1.0.0-beta3/reference.html

There are sections like source/output and elements like output.file.

If one wants to reference one of both items, (as I tried to do in my last mail 
to Josh)
one could do this by using section/element anchors:
http://savonet.sourceforge.net/doc-1.0.0-beta3/reference.html#SourceOutput
http://savonet.sourceforge.net/doc-1.0.0-beta3/reference.html#output_file

For users without javascript it would be helpful
  - to put a a name=output_file before the links of sections and elements.
  - to put the link href to this anchor. In this case the link href could be 
set to #output_file.
This enables browsers to jump to the right section/element when loading a page, 
referenced like above.

For users with javascript enabled, following code could be used to
show all sections or elements that are addressed in the URLwhen the page gets 
loaded :

 $(document).ready(function() {
 var parts=document.URL.split(#);
 if (parts.length1){
 var id=#+parts[1];
 $(id).parent().parent().show();
 $(id).siblings().show();
 }
 });

This was working already today for elements, since they provide a id already 
(like #output_file),
It could work even for sections, but sections have no id today (like 
#SourceOutput).

These changes would make the sections and elements linkable with both web 1.0 
and 2.0.

A more generic and efficient way would be, to provide for both items (sections 
and elements)
  - an anchor with the name of the link target
  - a link targeting this anchor
  - the content div which contains the id used to show/hide this element.

example
li
!-- provide a section anchor --
a name=SourceOutput /

!-- set link target to section anchor --
a href=#SourceOutputSource / Output/a

!-- have an id at the content to show/hide the content --
ul id=#SourceOutput class=liq-api-sec style=display: none;

li class=liq-api-elem
!-- provide a anchor --
a base=output_file /

!-- move id to content div, set link target to output_file --
a href=#output_fileoutput.file/a

!-- have an id at the content to show/hide the content --
div id=output_file class=liq-api-content style=display: none;
pre(?id:string,?append:bool,?dir_perm:int,?fallible:bool,.../pre
 ...
/div
/li
 ...
/ul
/li

 $(id).show();
instead of
 $(id).siblings().show();

you could use the link target (href) to address the content div id, which is to 
be shown/hidden.

anyway, the page works good as it is.

[Savonet-users] installation: required repositories/packages to build from HG (aac, aac+, soundtouch)

I just tried to install current version from latest HG.

There are some install dependencies I cannot resolve.
As I have learned for most package I need the libxxx and the

E.g. I like the way like ubuntu wiki does, where you can copy a 'apt-get

installation.

 You could give me the output of ./configure run from this folder?

 Also, you should remove libsoundtouch-ocaml-dev and more generally any
 packaged OCaml module that you are also compiling from source, in
 order to avoid liquidsoap picking up the wrong version..

 In the past I did not use these modules (aac/soundtouch,..),

 Yes, I will do that for the release.. In the mean time, except for

http://packages.debian.org/source/sid/liquidsoap
 The only difference is that all X11 and python related packages are
 used to build stuff you probably dont need..

[Savonet-users] using pulseaudio mix as input

2011-09-27 Thread Peter Retep

Hi,

I am trying to use the pulseaudio mix channel as input for liquidsoap.

Do you know how I can find out the names of available pulseaudio devices?
I played around with the names I see at audacity but unfortunately I did not 
succeed.

e.g. the following line will not work, since 'mix' is not the right device name.

liquidsoap 'output.file(%mp3, /tmp/test.mp3 ,input.pulseaudio(device=mix) )'

Background:

As you might remember we always wanted to have some dynamic scheduler to start 
a show (a single audio file) at a certain date  time.
I have written now a small scheduler which frequently scans all subdirectories 
below a storage /mnt/storage/ where start date and time is mapped to the path 
by convention.
e.g. if file /mnt/storage/2011/09/27/20-00/show.mp3 exists, show.mp3 will be 
started at 2011-09-27T20:00:00.
Starting a file means starting a cvlc for playout. (At our studio we put the 
playout audio directly on the sound mixer).

Directories are automatically created from our program schedule, so user just 
has to drop a file in the right folder.
To delete or move a show, user can still delete or move the file.
The scheduler takes care of file changes, even for shows that are in the past 
(like a show is inserted to be started a half hour before now).
This works good for now and has a very small cpu and memory footprint.

Now I would like to build a continous stream with help of liquidsoap to make 
the scheduler useful for other people, too.

Best regards, Peter

Re: [Savonet-users] using pulseaudio mix as input

2011-09-27 Thread Peter Retep

Hi Damien,

If a user does not follow the convention, his/her files will not be played.

Usually all shows are planned some weeks or days before. We use a google 
calendar for planning this.
The calendar synchronisation creates all directories from this and additionally 
creates the website entries with all show descriptions.
So mostly user dont need to create any directories, since this is automatically 
done if the show is scheduled at the calendar.
So user just needs to drop its mp3 file into the right directory. If there is a 
urgent need (e.g. someone has forgotten to schedule the show)
he sees all existing directories and can use them as template for the path 
convention. User does not even has to take care of the file name or any metatags
(except correct audio duration metadata).
The scheduler writes frequently current and next show to log. So you can check 
for errors, before the scheduler (or a cron job) would try to start a 
non-existing file.
Additionally I do not want to need the user to care about correct file paths in 
the jobs.
All of this should help to prevent misconfiguration or user errors.

There are multiple reasons why I do not to use a cron job for this:

- Most users I know, do not know even what a cron job is or what faults you can 
do when writing one.
   Additionally I would not like a separate cron job for each show (imagine 24 
shows a day, 365 days a year, ok, today we have only around 10 preproduced 
shows a week).

  - If there are any changes needed, the user just needs to update the file 
system.
So there is no database or any other redundant definition (like cron) of 
what is to be played when.

   - Furthermore the scheduler checks frequently if the current show player is 
running.
 If not, the start of the show will be cutted and played from the current 
position.
 This is useful for reboots due to power outages and other outages like 
process failures. The scheduler would be respawned by upstart on failure.
 Another case like this: the user puts the file at the right directory 
still one minute after the show should have been started (many users I deal 
with deliver their productions at the last minute .-)

As you can see the scheduler does a lot more than still starting a file at a 
certain time (e.g. logging, process audits, house keeping, etc.) to keep 
everything running

BR, Peter

 That looks useful. What if a user doesn't follow the correct dir/file

Re: [Savonet-users] hang up on full disk

2011-09-26 Thread Peter Retep

Hi David,

thanks for your answer!

Usually there is a housekeeping process which removes old files so there should 
always be enough free space.
Housekeeping just did not work under certain circumstances, which should be 
fixed by now - so there is no high priority on this issue.
I just learned that situations like this can happen even if one thinks about it 
before.
If a full archive device was not stopping the whole LS streaming process it 
could compensate admin failures and make LS even more robust.

I am still confused why ALSA and pulseaudio complain about missing space on the 
archive device,
since they are only used for reading from sound card, but not for output, but 
as told before, this is not high priority.

Best regards, Peter

PS:

I never would require LS to continue writing to disk, if disk is full.

Currently we have two outputs:
  - one to stream the content to the FM transmitter station and
  - one to archive the streamed content to disk (required by law in Germany).

There are two disks, one for running the system and a separate one used for 
writing archive only.
The archive disk was running full, the system disk was not full and the OS 
itself kept running.

 Hi Peter,

 First, thanks for the report and sorry for the very late reply.
 Unfortunately, I don't think we can do much about it, and I'm afraid
 it won't be our top priority. Most applications do not cope well with
 full disk -- or even full memory. Even if we could keep running part
 of the system when the disk is full, I'm not sure that a file output
 should keep running when it cannot write to disk anymore, as you're
 suggesting. It would be interesting to find a way to make this
 behavior optional, though.

 What is important however is (1) that liquidsoap is not the cause for
 the full disk and (2) that you can get enough info in the logs to
 figure out the problem, and fix it. As far as I can tell, this is more
 or less the case here.

 Cheers,

 The ogg is a litte trickier, i downloaded an swc library and the

 Would you recommend another technology to make an ogg/mp3 player?

 The problem is the iteration part where I return s,  else s0 ... which

 Am I close to it ?

 This was not the main motivation for adding it, but the new on_close
 will give you the actual filename which has been used, with the %H and
 other special things interpreted.

 A advantage would be that you dont need additional fix tools unless you use
 them.
 Yes, and it allows us to keep an encoder that works both for streams and 
 files.

 WAV: qwavheaderdump -F (quelcom package, tested).
 MP3: mp3check --fix-headers (not tested).
 Thanks for the reminder (though I don't know of any problem with the
 standard %mp3 output that needs to be fixed afterwards). Once you have
 tested one or both of these features, it would be nice if you could
 propose either a snippet for
 http://wiki.sourcefabric.org/display/LS/User+Snippets or a
 documentation paragraph for the %wav section of
 http://savonet.sourceforge.net/doc-svn/encoding_formats.html (or
 perhaps something to add to output.file's short documentation).

 Hi Peter,

 Romain and I didn't see a better solution than adding on_close, so I
 implemented it (commit b57a1b3bd7ae). Let me know how this works for
 you. For example, you may use
 output.file(%wav,file%Hwhatever.wav,on_close=fun(s)-system(qwavheaderdump
 -F #{s}),reopen_when={0m},...,source).

 Calling a external tool triggered by on_close would require to use the
 current filename in a command line, which is currently not supported.
 This was not the main motivation for adding it, but the new on_close
 will give you the actual filename which has been used, with the %H and
 other special things interpreted.

 A advantage would be that you dont need additional fix tools unless you use
 them.
 Yes, and it allows us to keep an encoder that works both for streams and 
 files.

 WAV: qwavheaderdump -F (quelcom package, tested).
 MP3: mp3check --fix-headers (not tested).
 Thanks for the reminder (though I don't know of any problem with the
 standard %mp3 output that needs to be fixed afterwards). Once you have
 tested one or both of these features, it would be nice if you could
 propose either a snippet for
 http://wiki.sourcefabric.org/display/LS/User+Snippets or a
 documentation paragraph for the %wav section of
 http://savonet.sourceforge.net/doc-svn/encoding_formats.html (or
 perhaps something to add to output.file's short documentation).

 Cheers,
