You’ve spent a lot of time and money collecting digital music. And by now, you have a pretty sweet library of MP3s and AACs to show for the effort.

But let’s say you want to take that library to go? Before you start carrying around a huge hard drive, you might want to try streaming your tunes online instead. All it takes to start streaming your music over the internet is a playlist, a server with some storage space, and a software player that can open and play an internet stream.

Step 1: Host it somewhere

Most web hosts offer data plans around $10 per month that come with plenty of storage and bandwidth to hold and serve your music. The rates get steeper once you want to store more than 200 or 300 gigabytes. Also, when you’re streaming, you’re paying for bandwidth. So, if you’re looking to share your collection with your friends as a stream, you’ll have to monitor your usage more closely or else end up paying through the nose.

Besides the cost, you trade off a good deal of control over the data because it resides on some machine out there in the ether.

Hosting music on your own computer using a broadband connection is a preferable option, especially since you know exactly where it is and there’s is no need to transfer your music anywhere. However, unless you have a static IP address, finding your computer (and your music) in the vast expanse of the internet can be a hassle. If your network provider keeps changing your IP address on you, try setting up Dynamic DNS using a service like DynDNS.

Tip: Webmonkey.com has an excellent introduction to using Dynamic DNS.
Tip: Dan Hilgert also has an explanation of his Dynamic DNS setup and streaming music guide.

Step 2: Create a playlist

Perhaps the easiest way to get your music online is to use your favorite music player. Most music players, including iTunes, Windows Media Player and WinAmp all use common playlist formats to play music online.

A playlist contains the names and location of your music files. It is downloaded and used by your media player to play the music files as a stream. It works pretty well, although the music players don’t allow skipping, fast forwarding or rewinding.

The most-used music file formats are MP3, Windows Media Player’s WMA and Apple’s mp4 (also known as AAC). We recommend using only these player files for universality. If you’re not sure which format to use, we’d recommend you default to MP3 to ensure the ultimate in compatibility.

Extended M3U

The easiest and most reliable method for streaming is to use M3U playlist files in conjunction with iTunes or Windows Media Player. Open a streaming URL by pressing Control-U (or Command-U for Mac) in either program.

An extended M3U file format looks like this:

#EXTM3U

#EXTINF:Birds In The Belly http://www.soundsofarcadio.com/mp3/BirdsintheBelly.mp3

#EXTINF:Hock It Like You Own It http://www.soundsofarcadio.com/mp3/HockItLikeYouOwnIt.mp3

#EXTINF:Kid I Know http://www.soundsofarcadio.com/mp3/AKidIKnow.mp3

You can follow the format shown above. Open the code up in a text editor and just paste in your own song info and URLs. When you’re done building your list, save the result as a .m3u file and open it up in your player.

If you’re a Windows user, you can download M3U Creator. The free desktop application will let you create and edit .m3u playlists in an easy-to-use interface.

XSPF

Another common playlist format is XSPF (pronounced “spiff”). This method is more practical for streaming music via a web page or Flash-based players, though many third-party applications support XSPF. For example, Yahoo Music Jukebox uses XSPF as its default playlist format.

The XSPF format is below. Note the “L” in “trackList” needs to be capitalized for it to be recognized by players.

<?xml version="1.0" encoding="UTF-8"?>
<playlist version="1" xmlns="http://xspf.org/ns/0/">
     <trackList>

       <track>
         <location>http://www.soundsofarcadio.com/mp3/BirdsintheBelly.mp3</location>
         <creator>Arcadio</creator>
         <album>Early Demo</album>
         <title>Birds in the Belly</title>
       </track>

       <track>
         <location>http://www.soundsofarcadio.com/mp3/HockItLikeYouOwnIt.mp3</location>
         <creator>Arcadio</creator>
         <album>Early Demo</album>
         <title>Hock It Like You Own It</title>
       </track>

       <track>
         <location>http://www.soundsofarcadio.com/mp3/AKidIKnow.mp3</location>
         <creator>Arcadio</creator>
         <album>Early Demo</album>
         <title>A Kid I Know</title>
       </track>

     </trackList>
</playlist>

Again, to make your own playlist file, just copy this code into a text editor, change the song info and the URLs, and save the results with the extension .xspf.

For a list of players and uses for XSPF files, visit the XSPF applications page. Included in the list is an M3U to XSPF file converter and some command line tools used to generate XSPF files from various music libraries online.

There are also some handy validation tools to make sure your spiffs are well-formed.

PLS

The PLS format is another streaming playlist option, and used mostly by professional online radio broadcasts. You’ll find a good deal of PLS-streaming music stations on Shoutcast.

The PLS file format looks like this:

[playlist]
NumberOfEntries=3

File1=http://www.soundsofarcadio.com/mp3/BirdsintheBelly.mp3
Title1=Birds in the Belly
Length1=-1

File2=http://www.soundsofarcadio.com/mp3/HockItLikeYouOwnIt.mp3
Title2=Hock It Like You Own It
Length2=-1

File3=http://www.soundsofarcadio.com/mp3/AKidIKnow.mp3
Title3=A Kid I Know
Length3=-1

Version=2

Length refers to the length of the song. Use -1 to have the music player ignore it entirely.

Download Software to Do It For You

Otherwise, you might want to give Shoutcast’s broadcasting tools a try. Shoutcast’s tools are extensions built on the Windows-only WinAmp music player, but some broadcasting tools for Mac and Linux are also available.

If you already have WinAmp, Spacial Audio Solutions offers a plugin to turn it into an internet radio station. Spacial also has software for the enthusiastic amateur and professional: SimpleCast and SAM Broadcaster.

iRadeo is a free streaming audio platform that allows anyone to start an online radio station. Once installed, iRadeo will automatically detect and stream any MP3 or WAV file formats that has been uploaded to the specified directory.

Finally, Peercast provides both direct and P2P streaming at the same time, allowing you to stream music online anonymously.

Don’t Feed the Lawyers

You could be fined for broadcasting music you don’t own the copyright to, and in most cases the penalties are pretty severe. There are also plenty of rabid music industry lawyers with a history of going to great lengths to prosecute copyright violators. That said, be careful how you distribute your streams.

Some of the software solutions listed here have built-in password protection. Otherwise, you’ll have to know some SSL and/or password protection web hosting configurations to lock down your stream.

Your other option — and probably the safest — is to just keep your station under wraps. You can listen to it freely, but don’t go spreading the word. Remember, the internet has ears!

A: Entweder sind Einstellungen in Traktor Pro oder der icecast.xml nicht korrekt oder eine Firewall verhindert den Zugriff auf den IceCast-Server

Vazaram na rede as imagens exclusivas do último podcast Na Varanda, feito ao vivo, no dia 08/08 do corrente ano. Imagens raras, perturbadoras e principalmente, constrangedoras, do primeiro podcast feito por homens grávidos do mundo. Uma noite lacinante. As imagens são fortes. Retirem crianças, cardíacos, pessoas com cistite, idosos com baixa imunidade e pessoas com uma perna mais curta que a outra da frente do computador. Nenhum código aberto foi maltratado durante este podcast.

Para os detratores, o podcast é realmente feito Na Varanda. Ao fundo o saudoso bambuzal

Centro de comando interativo. Nome luxuoso para o "cara que fica vendo Twitter e outras porcarias interativas". De costas, Jude Law

Simples ferramenta para streaming ao vivo em Software Livre, o Icecast, para provar ao ENIAC da EBC que não é preciso milhões e grandes parques computacionais para produzir conteúdo na rede

Momento TENSO! Âncora @fernandoike consola @cesaraovivo que está inconformado com a perda do bambuzal, observados por Cascardo e Lincoln (blusa verde).

Editor de som Audacity usado para gravar o podcast

Jude Law coordena a equipe na transmissão, sentindo cheiro estranho vindo do conteúdo. Equipamento: amplificador, mesa de som Behringer, mic de lapela e mic Shure

Termina o Na Varanda, o único podcast em que os apresentadores ficam bêbados ao longo do programa

Note: While this *can* be done on Windows, this guide will be for Linux. There are only minor differences, but I’ll let you work those out yourself.

Before you start, keep in mind that video streaming is VERY cpu and bandwidth intensive. Audio streaming is OK, but the methods described here uses transcoding, which means one decoder and one encoder will be active per stream. Music streaming at 128k should take about 10kb/s, and is a lot nicer to your cpu

Step 1. Setting it up!

1. Start by grabbing the packages icecast2, ezstream, ffmpeg2theora, madplay, podget. A few others may be required, but I think those should do for now.
2. Create a new user, ezstream, and change to its home directory /home/ezstream
3. Change ezstream’s cron with sudo -u ezstream crontab -e ; Create a script to run every hour, as “podget”

Step 2. Configuring podget

Sudo to ezstream with sudo -u ezstream bash. Create the folder ~/.podget and open ~/.podget/serverlist in nano. If it has contents in it, wipe it all out and then put in one line per podcast, looking like http://host.com/feed/rss.xml channel1. Replace channel1 with whatever you want to call the channel. You can add several feeds to several channels, just remember that the channel name can’t contain any spaces!

Now run podget and make sure that it works. Ctrl-C it and open ~/.podget/podgetrc in nano. Modify the download path to be /home/ezstream/media. Now go back out and create the media folder. Delete the old downloads folder, and run podget again. It should now download the content into the different channels. If you also changed the days to keep the file in podgetrc, old episodes will get automatically deleted.

3. We got the episodes, now what?

Next we need to create our playlist scripts. Open /home/ezstream/playlist/channel1 in nano, add the #!/bin/bash header and put in ls /home/ezstream/media/channel1/*.mp3 | sort -R | tail –lines 1 ; Save the file and make it executable. If you’ve got any media downloaded so far (it takes a while, so seriously, if you don’t; type “screen podget” and then detach. right now!) you can type /home/ezstream/playlists/channel1 and hit enter, and you should get a random media file in return. Sorted? Good!

When you have a script for each of your channels, you can move on to the next step.

4. Streaming it…

We will be using ezstream to decode the files and then pass them on to the icecast server. Grab the two templates, save them as /home/ezstream/conf/template-audio.xml and template-video.xml. Next, make a copy of one of these files as channel1.xml and open it with nano. Update the path and the password at the top, and make the playlist point to /home/ezstream/playlists/channel1. Save and exit. Create one of these for each of your channels. Now to launch the streams.

5. Really streaming it…

This part is far from the ultimate solution, but it works. use exit to go back to your normal user account, and type sudo nano /usr/bin/streamstart. Give it the bash header, and then put in: sudo -u ezstream ezstream -q -c /home/ezstream/conf/$1.xml > /home/ezstream/logs/$1.xml ; Go back out and create the ~/logs directory. Make the file executable.

6. Setting up Icecast

Piece of cake. Issue sudo nano /etc/icecast2/icecast.xml and hack away. Change the passwords as needed, increase the number of sources, save and exit. Try sudo /etc/init.d/icecast2 start and keep your fingers crossed. If you can access localhost:8000 in your web browser you have been successful. If not, work out the kinks and try again.

7. Going live!

At the prompt, issue streamstart channel1. This should fire up ezstream which should start re-encoding and streaming your media. Open the target URL in your media player to make sure everything is working. Congratulations

Possible improvements

• Rewriting the playlist script to check for new items and put them first, so that a news show will air while it’s “hot”.
• A streamstop command could find the pid for the ezstream command and kill it, thus stopping the stream.

Important! You are NOT blind. There are no downloads. YET! I will put them up asap.

I wanted to do a demonstration of live streaming using the <video/> tag for my talk at the upcoming Open Source Bridge conference; maybe a stream a surprise guest in, do some audience interaction, something fun. I figured the easiest way to test the streaming myself would be to use the webcam in my MacBook Pro’s built-in iSight camera.

I pinged Asa to get details about how he streams Air Mozilla, which brought Icecast into the picture. I found some old posts about using VLC on Linux to capture the external iSight, so tried it… but no dice, the capture module barfed when trying to talk to the camera. VLC ships with a capture module for the iSight, but hasn’t been updated to work with the internal iSight. Bah. VLC also supported transcoding to Ogg Theora, as well as streaming to Icecast servers, so it really seemed like it’d provide just about everything, if it only supported the camera.

I looked up the error I got from VLC, posted on the VLC forums, no answers. So I emailed the author of VLC’s Quicktime module, Pierre d’Herbemont, at the email he left in the source file. After a couple of emails, and less than 24 hours later, he’d checked in a fix. Open source FTW. Thanks Pierre.

The steps to get it working are enumerated below. At some point, the VLC fix will ship, but until then you’ll need to use nightly builds.

Install and configure the Icecast2 server:

1. Install MacPorts
2. In the Terminal: sudo port install icecast2. This installs everything into various dirs in /opt/local.
3. Edit /opt/local/etc/icecast.xml, set user/group it runs as (for logfiles, i set mine to _www, same as Apache), and change the default passwords in the authentication section.
4. Set permissions on /opt/local/var/log/icecast to be writable by the user you configured Icecast to run as.
5. In the Terminal, start the server: sudo icecast -c /opt/local/etc/icecast.xml -b
6. Test your install by checking the server’s status at http://localhost:8000/status.xsl
7. Watch the log in the Terminal: tail -f opt/local/var/log/icecast/error.log (Useful for confirming VLC access, as well as catching authentication problems)

Start the stream:

1. Download and install the most recent VLC nightly build
2. Open the terminal, and execute the command below
3. Open http://localhost:8000/stream/isight with Firefox 3.5b4 (or newer)

VLC Command (all one line):

/Applications/VLC.app/Contents/MacOS/VLC qtcapture:// –sout=”#transcode{vcodec=theora,vb=256,venc=theora,acodec=vorbis,ab=64,aenc=vorbis}: standard{access=shout,mux=ogg,dst=source:yourpassword@localhost:8000/stream/isight}”

It’s still not quite ready for practical use:

• There’s still some size distortion, maybe I have the aspect ratio wrong or something
• Still working on sound
• Lag is pretty bad

When coming from a working streaming server, adding static files streaming is rather simple. The only snag is with the <webroot> directive in the <paths> section.
When you change the <webroot> location to point to your MP3 collection, you will cripple part of your administration web-pages.
The way I solved this is to create a symbolic link in the by <webroot> pointed directory.
So, switch on the functionality for streaming static files by:
<fileserve>1</fileserve>
and then, if your <paths> section looks like this:
<paths>
<webroot>/usr/share/icecast2/web</webroot>
<adminroot>/usr/share/icecast2/admin</adminroot>
<alias source="/" dest="/status.xsl"/>
</paths>
you would create a symbolic link:
ln -s /path/to/my/mp3/collection /usr/share/icecast2/web/popular
To play a song: Point a streaming media player to:
http://icecast.myserver.priv:8000/popular/mysong.mp3

Now that I’ve got time at had, I picked up several projects that were left dangling due to projects that paid the rent…

I’ve come a long way with Nagios, PowerFuse and some others, but IceCast has some documentation and is the first to be published. It’s still a bit sketchy, but it gives an acual overview of what to expect: Something that I did not find elsewhere on the web.

As you can see in the schematic overview, icecast is not meant to be used alone: At least a consumer is needed to listen to the stream.

Icecast has two major ways of providing content: By “static files” or through a stream. The diagram shows the necessary components to come from .OGG files to a live audio stream.

To cut to the chase: In order for icecast to stream audio it needs a source.
MPD can be such a source. There are others, see the mindmap)
In order for MPD to know what it needs to send, it needs input, “PitchFork” can be such a control program.
In short: MPD knows of a list of audio files, PitchFork can request this list of files and shows a neat overview, you select files to be played, PitchFork instruct MPD what to play and MPD sends it to IceCast to be streamed world wide.

En la insitiución donde trabajo se viene requiriendo configurar un servidor de streaming para tener una radio en linea, q será alimentado desde una tarjeta de sonido al cual estará conectado el equipo de radio, una arquitectura interesante, por lo que me puse  a investigar y como se dice una imagen vale mas q mil palabras, me encontre con esta imagen que resume todo lo q deseo hacer:

Imagen: http://federicosayd.wordpress.com/2007/10/12/una-radio-en-linux/

Bueno yo ya habia trabajado con shoutcast, el problema es que nunca le encontre un cliente para que alimente al servidor y que corra en linux ademas que no soporta el formato ogg. Por lo que le di una oportunidad a icecast, anteriormente lo habia probado pero tuve problemas para configurarlo, pero esta vez ya me funciona.

En esta parte explicare la configuracion de icecast y de ices, el primero es el servidor y el segundo es el cliente que alimentara a nuestro servidor:

• Instalamos icecast con los USE flags siguientes: “speex ssl theora yp”

# emerge -va icecast

• Configuramos icecast en el archivo /etc/icecast2/icecast.xml

• Creamos el directorio /playlist.ogg y agregamos los archivos ogg que queremos:

# mkdir /playlist.ogg

• Creamos el listado de los ogg que vamos  a reproducir:

# find /playlist.ogg/ -iname “*.ogg” > /etc/ices2/listado.txt

• Iniciamos los servicios:

# /etc/init.d/icecast start

# /etc/init.d/ices start

• Para que arranquen a la hora q inicia nuestro sistema

# rc-update add icecast default

# rc-update add ices default

Para reproducir nuestro streaming desde un navegador vamos a:

http://ip_server:8000/playlist.ogg.m3u

o sino en http://ip_server:8000 nos aparecera un  link hacia ese archivo que lo reproduciremos en mi caso con amarok.

Envie de partager vos excellents goûts musicaux et de faire un tour au tribunal? Faites de la radio et 3 mois de prison avec IceCast2 et MPD!

IceCast2

Icecast est le programme qui permettra de diffuser votre radio. Ce n’est pas un lecteur en lui même mais plutot un serveur. Première chose à faire: l’installer!

sudo apt-get install icecast2

Ensuite on détermine les mots de passe nécessaire a son administration en éditant le fichier suivant:

sudo nano /etc/icecast2/icecast.xml

<authentication>
        <!-- Sources log in with username 'source' -->
        <source -password>password1</source>
        <!-- Relays log in username 'relay' -->
        <relay -password>password2</relay>

        <!-- Admin logs in with the username given below -->
        <admin -user>admin</admin>
        <admin -password>password3</admin>
    </authentication>

source-password est le mot de passe qu’utilisera MPD pour se connecter à Icecast2
admin-password est le mot de passe de l’administrateur pour se connecter à l’interface web d’IceCast2
Nous n’utiliserons pas de “relay-password” mais il est préférable de le changer pour plus de sécurité.

Pour activer Icecast, éditez le fichier suivant:

sudo nano /etc/default/icecast2

et à la fin du fichier, changez “ENABLE=false” en “ENABLE=true”. Enfin lancez Icecast:

/etc/init.d/icecast2 start

Si tout va bien, vous devriez pouvoir accéder à l’interface Web via l’adresse suivante http://192.168.0.100:8000/ (en prenant soin de remplacer 192.168.0.100 par l’IP adéquate).

Rien a faire sur cette page, tout ce qu’il vous reste a faire est de configurer MPD.

MPD

MPD est le lecteur qui transmettra la musique à IceCast2 au format adéquat

Si vous ne savez pas comment installer MPD, suivez ce guide. Si vous avez déjà MPD d’installé et que vous voulez en lancer une seconde instance, suivez ce guide.

Dans tous les cas, éditez votre fichier de configuration (mpd.conf) et dans la section “### AUDIO OUTPUT ###” commentez toutes les lignes et ajoutez celles-ci:

audio_output {
 type                    "shout"
 name                    "Le Nom De Votre Radio"
 host                    "localhost"
 port                    "8000"
 mount                   "/radio.ogg"
 password                "votre mot de passe"
#        quality                 "5.0"
 bitrate                 "98"
 format                  "44100:16:1"
}

type ne changez pas cela
name Le nom de votre radio
host l’IP de la machine ou se trouve IceCast2
port ne changez pas cela à moins d’avoir changé le port d’IceCast2
mount L’extension de l’adresse de votre radio. Dans l’exemple ci dessus (radio.ogg), l’adresse deviendra http://IP.IP.IP.IP:8000/radio.ogg
password le “source-password” défini dans /etc/icecast2/icecast.xml
quality et bitrate qualité et débit de l’encodage ogg-vorbis, choisissez-en un et commentez l’autre.
format le format en Hertz/Bit/Canaux

et surtout n’oubliez pas la dernière accolade “}”.

Une fois le tout terminez, lancez votre musique favorite et branchez vous sur votre radio (http://IP.IP.IP.IP:8000/radio.ogg) pour écouter votre travail pendant qu’il en est encore temps. VLC est parfait pour ce genre de job.

Notes

Partager de la musique sans soudoyer votre voisin c’est bien c’est mal, que ce soit de la musique libre ou soumise à des droits d’auteurs. Dans tous les cas on se fait baiser, il faut payer la SACEM un minimum de 60€ par mois.

“(…)même si l’oeuvre n’est plus protégée (domaine public), l’autorisation des titulaires de droits voisins (producteurs/artistes-interprètes) est également indispensable lorsqu’un disque (CD) est reproduit.

Ainsi l’enregistrement (au format MP3 ou tout autre format) pour mise à disposition sur les réseaux (Internet notamment), sans autorisation, constitue une contrefaçon aux termes du Code de la propriété intellectuelle, délit susceptible de poursuites pénales, et sur le plan civil, de dommages et intérêts.” SACEMal

This post discusses how to distribute music to a collection on locations around a single house, but it works equally well for distributing music across the internet since it involves creating an internet-based streaming “radio station” using icecast, as well as Airtunes.  It is an abbreviated version of the posting at the RoboSci blog that provides a lot more details.

I had hoped to get people dancing (and failed), but as an aside I arranged to broadcast music around the house to several locations on 2 floors. To do this, I used iTunes (on a Mac) to produce a playlist. The problem then, was how to distribute a synchronized playlist to at least 3 locations within the house. As an aside, I wanted to use icecast (i.e. shoutcast) so I could do other stuff as well like (later on) broadcast outside the house. The Shoutcast protocol can be used to broadcast to Macs, Windows, Linux, FreeBSD and Solaris (and more). Shoutcast is freeware while the compatible Icecast (or Icecast2) is true GPL (and I believe it was released before Shoutcast became free).

Option 1: Use Airport Express: The easiest way to do this is to use airport express wireless “bricks”. You can broadcast to these easily from iTunes, and it it just works. My problem was that I didn’t have enough Airport Express bricks; some locations had to be actual computers, but iTunes does not support broadcasting to another computer.

Option 2: Use Airfoil: There is a software package called Airfoil. This allows you to capture the audio output (from any program) and broadcast it to an Airport Express unit, or to a mac or Windows computer running their free Airfoil Speakers application. It’s very nice and only costs $25. Being a bit of a hard-core hacker, I was interested in an icecast solution I could roll myself, for several reasons including the fact it would allow me to subsequently broadcast content over the internet, for example to my office.

Option 3: Roll my own Icecast2 server: this is what I chose to do and what the details describe.

It is described in detail at http://www.dudek.org/blog/140

Icecast é um servidor para rádio web e transmissão de streaming.

Instalação do Icecast:

Instale os seguintes pacotes:

1. libogg
2. libvorbis
3. libxml2
4. libxslt
5. curl

Abra o terminal como root e execute:

# apt-get install icecast2

Configuração:

Abra o arquivo icecast.xml no diretório /etc/icecast2/ (onde vc tiver salvo)

<limits>

<clients> números de usuários conectados suportados pelo servidor
<sources> número total de fontes de streaming suportados pelo servidor

<autenticathion>

<source-password> senha para se conectar ao icecast
<admin-user> usuário para acessar a interface do icecast
<admin-password> senha de acesso à interface

<Configuração do servidor: endereço, porta>

<hostname> host ou IP do servidor

Rodando o Icecast:

Digite o seguinte comando no terminal:

# chown root.root icecast2

# chmod 755 icecast2

# /etc/init.d/icecast2 start

Verificar em:

http://hostname_ou_IP:800/status.xls

Bueno, hace mucho que no escribo por aquí, pero ahi vamos otra vez.

Esta vez vamos a referirnos a trasmitir “radio” desde Ubuntu, y cuando digo radio, me refiero tambioén a la radio.

Cómo vieron en el anterior tutorial, tenemos una placa de TV funcional bajo linux, y la misma tambien tiene radio. En la placa Encore, el dispositivo de radio es “/dev/radio0″.

Para escuchar la radio yo utilizo:

gnomeradio.

sudo aptitude install gnomeradio

o fm (línea de consola)

lo instalamos con:

sudo aptitude install fm-tools

para usarlo hacemos desde consola

“fm 95.1 65536″ o sea le decimos cual es la frecuencia y el parámetro de volumen.

Ahora si vamos a lo nuestro, primero tenemos que instalar el servidor de streaming, Icecast2 en este caso, y luego el programa source.

1 – instalacion y configuracion de icecast2.

la instalacion es muy simpl

sudo apt-get install icecast2

Luego sudo gedit /etc/icecast2/icecast.xml

[...]
    <authentication>
        <!-- Sources log in with username 'source' -->
        <source-password>password1</source-password>
        <!-- Relays log in username 'relay' -->
        <relay-password>password2</relay-password>

        <!-- Admin logs in with the username given below -->
        <admin-user>admin</admin-user>
        <admin-password>password3</admin-password>
    </authentication>
[...]

Aquí cambiamos el pass tanto para Source como para Admin.

sudo gedit /etc/default/icecast2

# Defaults for icecast2 initscript
# sourced by /etc/init.d/icecast2
# installed at /etc/default/icecast2 by the maintainer scripts

#
# This is a POSIX shell fragment
#

# Full path to the server configuration file
CONFIGFILE="/etc/icecast2/icecast.xml"

# Name or ID of the user and group the daemon should run under
USERID=icecast2
GROUPID=icecast

# Edit /etc/icecast2/icecast.xml and change at least the passwords.
# Change this to true when done to enable the init.d script
ENABLE=true

Ahora arrancamos  el demonio Icecast2

sudo /etc/init.d/icecast2 start

2 – instalacion y configuracion de ices2 u otro programa Source

Podemos usar IDJC (Internet DJ Console), para ello necesitamos JACK.

sudo aptitude install jackd idjc

arrancamos primero Jack Control y luego Internet Dj Console.

Podemos usar Muse tambien.

O podemos usar Ices2 y seguro otros más.Para Ices2

sudo aptitude install ices2

Copiamos un fichero default

cp ices-alsa.xml /home/tu_usuario/

cp ices-live.xml /home/tu_usuario/

editamos ambos ficheros a nuestro piacere y luego lanzamos:

ices2 ices-live.xml o el otro fichero.

Debemos jugar con las entrada Mic – Line, o Mic1 mic 2 en nuestro mixer.

y luego podemos ir a http://ip:8000/puntodemotaje.ogg y escuchar desde otro equipo

<password>hackme</password> in <password>primapassword</password>

Creare il file /etc/ices2/playlist.txt
find /etc/ices2/music -name *.ogg > /etc/ices2/playlist.txt

Riavviamo icecast e lanciamo ices2:
/etc/init.d/icecast2 stop
/etc/init.d/icecast2 start
ices2 /etc/ices2/ices-playlist.xml

Fine

J’ai personnellement un portable (ou plutôt 2, passons…) et un serveur. Le portable me sert pour surfer, t’chatter, blogger, bosser (accessoirement) et plein d’autre trucs comme tout le monde. Cependant je ne me vois pas avec toutes mes données directement dessus, premièrement d’un point de vu sécurité (comment faire si il tombe du 25ème étage sous les roues d’un semi-remorque…) mais aussi parce que avoir des données sur mon portables ça ne me permet d’y avoir accès que lorsque celui-ci est à coté de moi… et seulement pour moi. Dans cette optique et pour pouvoir mettre en pratique et expérimenter certaines chose en rapport avec mes études, j’ai mis en place un serveur sur lequel j’ai quelques services, dont un serveur de stockage (la base quand on se monte un serveur). Dans les données stockés, j’ai bien évidemment la musique que j’ai chèrement payé et ‘numérisé’ afin d’y avoir accès de tout mes postes simplement.

Cependant avoir votre musique sur un serveur chez vous et rien sur votre portable, ça vous donne des séances de projets tuteurés à l’université assez moroses. J’ai bien essayé un petite connexion SSH pour récupérer quelques pistes via scp, mais le tout est pas très rapide et pas très utilisable. À partir de là, une idée qui me trottais dans la tête depuis quelques temps m’a semblé devenir indispensable…

L’idée c’est d’implémenter un service de stream sur mon serveur qui diffuserai à la demande et de façon très restreinte la musique que j’ai. Après quelques recherches, j’ai trouvé une solution qui me convenait assez bien, à savoir MPD (que j’utilise déjà quand je suis en local) pour lire la musique sur le serveur, commandé par une interface web grâce à pitckfork, le flux produit par MPD étant dirigé sur Icecast2 afin d’y être transformé en flux stream. Ce flux reste en local car je ne souhaite pas que n’importe qui écoute en même temps que moi. Il sera donc nécessaire d’établir une connexion ssh avec redirection de port pour y avoir accès.

Après la parlotte, passons à la pratique. Je vous laisse installer MPD, Pitchwork (ou autre, Pitchwork n’est pas la seul interface web pour MPD mais cependant je la trouve assez réussi) et Icecast suivant les distributions que vous avez. Je ne m’intéresserai qu’à la configuration de MPD et Icecast2.

MPD :

Dans /etc/mpd.conf hormis la configuration par défault qui consite à indiquer l’emplacement de votre musique, des playlist, de l’utilisateur pour lequel MPD est lancé etc… ce qui nous intéresse est ce qui se trouve sous la bannière :

################ SHOUT STREAMING ################

Je vous met à la suite la configuration pour l’un de mes flux (j’ai configuré MPD pour avoir un flux ‘haute qualité’ et un ‘moyenne qualité’ ) Le détail est en dessous

audio_output {
type “shout”
name “Thot’s HQ stream”
host “localhost”
port “8000″
mount “/hq.ogg”
password “abcdefgh”
quality “5.0″
# bitrate “128″
format “44100:16:1″
#
# Optional Paramters
user “source”
description “Flux Haute Qualitée”
genre “All”
}

audio_output{ } est obligatoire et indique la configuration d’une sortie audio (vous vous en seriez doutés) celle-ci peut etre pour une sortie physique ou comme ici vers un fichier, spécifié par l’argument ‘ type “shout” ‘.

Viens ensuite le nom que vous voulez lui donner, celui-là même qui apparaîtra dans Icecast. Host et port définissent où est envoyé le flux de sortie, en l’occurence sur le même hôte vers le port 8000.

Mount défini le ‘point de montage’ c’est à dire l’emplacement ou sera disponible ce flux Dans notre cas : http://localhost:8000/hq.ogg

Le mot de passe qui suit est celui qui servira entre MPD et Icecast. Notez le, il vous sera redemandé par la suite.

Viennent ensuite quelques paramètres de qualités que je vous laisse analyser, le paramètre ‘user’ qui définit le nom utilisé pour se connecter à Icecast et en ‘optional parameters’ des infos qui seront affichés en rapport au stream diffusé.

Pour MPD ça sera tout, si vous souhaitez plus de renseignement, n’hésitez pas à consulter la page MPD sur ubuntu-fr.org

Passons à Icecast :

Le fichier de configuration est au format XML et se trouve dans /etc/icecast2/icecast.xml

Je ne vous détail pas tout les paramètres, ils sont très nombreux et pas tous intéressants. Ce qui nous occupe se trouve entre les balises <authentification> :

<source-password>abcdefgh</source-password>

C’est ici qu’il faut placer le mot de passe spécifié dans mpd.conf

<admin-user>admin</admin-user>
<admin-password>change_me</admin-password>

Ces deux paramètre servent pour accéder à la partie admin de l’interface web.

Vérifiez aussi la balise suivante et la configuration pour une utilisation basique devrait être suffisante.

<hostname>localhost</hostname>

Il ne vous reste plus qu’à redémarrer mpd et icecast après quoi vous pourrer lancer la diffusion avec mpd (via pitchfork) et écouter ce qui en résulte avec VLC par exemple en choisissant la lecture d’un flux réseau pour lequel vous indiquerez donc :

http://ip_du_serveur:8000/nom_du_flux.ogg

Je ne saurais que vous conseiller de ne pas ouvrir ce port sur internet et, lorsque vous souhaiterez en profiter depuis l’extérieur, d’ouvrir une session ssh avec redirection de ce port pour une plus grande sécurité.

Si vous avez des soucis d’installation ou de configuration, je suis dispo.

After trying almost every audio media player out there for Linux, I finally found the most versatile and user friendly one – BMPx. What especially won me over about BMPx was the user interface. It is intuitive and organized with almost no settings to configure and no menus to get lost in. This is thanks to the fact that BMPx is fresh and it’s not trying to throw in a hundred useless features like the competition. It gets better, BMPx gives you 7 music sources: Shoutcast, Icecast, MP3’s, Podcast’s, Last.fm, audio CD’s and Jamendo. BMPx stands for Beep Media Player experimental and it is mainly coded by Milosz Derezynski. It’s an evolution of the previous Beep Media Player which was based on XMMS and Xine, now BMPx is all original and gstreamer based. You can download BMPx from its’ official home page and compile it yourself. If your distro is Debian based you are in luck, you can download the package from getdeb.net. I wouldn’t recommend downloading it from the universal repository as it will give you an older version of the player. To use it you will also need the appropriate codecs. You can download the individual gstreamer codec packages, but the easiest thing to do if you are using Ubuntu is to download the restricted extras package using “sudo apt-get install ubuntu-restricted-extras”. Finally, on to my review!

I use the radio feature most of the time as I quickly destroy my own music collection by repeatedly listening to my favorite songs. BMPx has two of the most popular radio station directories to choose from: Shoutcast and Icecast. They are both integrated into the graphical shell, so there’s no need to open your browser to start a stream. Since Icecast doesn’t have that many stations, all 1,500 stations are loaded for you; but you will have to update the list manually from the menu during your first use. Shoutcast stations are loaded by genre due to the fact that there are a total of over 20,000 stations. If you are looking for a particular station, you can simply use the search bar at the top. The Shoutcast functionality is a bit more refined and it makes it easier for you to find a good station by giving you a list of the top 500 radio stations. Once you’ve picked out a few stations that you like you can then add them to your favorites; but unfortunatelyyou cannot later remove them from your favorites due to BMPx’s beta stage. As a bonus, most internet stations don’t have commercials, they don’t have any annoying chit-chat and they are streamed in CD quality sound.

If 21,500 radio stations are not enough to satisfy your music hunger, there’s Last.fm. What makes Last.fm unique is its’ audioscrobbler feature. The Last.fm audioscrobbler personalizes the music stream based on your personal music taste. You simply input the name of a song or artist and the audio scrobbler will try to match the exact initial song and then it will try to match the same taste of music in the following songs. Once you get Last.fm going, the top-left box will display relevant matches allowing you to choose exact track you had in mind. The right box will display all of the tags (eg. funk, rock, etc…) related to the song you are listening to; you can click on one of these to further fine tune your radio stream. The left-bottom box displays your information such as your personal music tags and what your friends are listening to. Once Last.fm has started playing your music you can skip songs and fine tune your stream even further by letting the audioscrobbler know what songs you like and dislike by pressing the appropriate button in the menu. In addition to that, you can let the audioscrobbler know which personal MP3’s and Jamendo tracks you like and dislike to further fine tune your radio stream. This all sounds great in theory, but I still prefer the playlist a live music DJ provides. In actuality, Last.fm makes listening to music boring as each track is almost like the previous one – variety is good.

Your personal MP3 collection is displayed in a systematic manner where by you first select the artist, then album and then the track, thus allowing you to manage your music accordingly. It couldn’t be any easier, but there were some problems. I did have a problem with one MP3 which was causing BMPx to crash, in addition to that I couldn’t get the cover art to display in the album box. Anyhow,besides having MP3 support, BMPx supports Ogg Vorbis, FLAC, MOD, MPC, MP4, AAC, M4A, WMA, SID, WAV and SPC codecs. You can explore your existing collection by right-clicking on the track to get more information about the artist from the internet. And if you would like to sing along, you can right-click on the track and download the lyrics from an internet server. The two former features are actually available globally, including in the radio, CD player and in Last.fm. Navigating through your music globally within BMPx is easy with a few keyboard shortcuts, there even is an option to enable global Linux hotkeys. BMPx minimizes to your tray while still giving you full control of the player. Right-clicking on the tray icon give you full track control and left-clicking restores the BMPx window. Hovering your mouse over the tray icon displays the track information, including cover art. For those of you who have a large MP3 collection, search is simply enabled by typing on the keyboard.

Managing your playlist in a single album is a breeze thanks to the boxes you check and uncheck to select the song that you would like to play. If you are creating a play list from multiple albums you have to right-click on the tracks the you would like to enqueue. What is really annoying about this feature is that you first have to left-click on the track before you can right-click on it. The playlists can be saved and exported in a variety of popular formats, but what is really impressive is the ability to create a playlist based on a Last.fm tag.

The podcast feature in BMPx is just as intuitive as all of the other features in BMPx. Your podcast link is even automatically pasted into the URL entry field when you select to add your podcast via the menu. Once added, the top pane will display your different podcasts, the left bottom box will display the actual downloaded podcasts and right-bottom box will display the actual podcast info. To delete an old podcast you simply uncheck the box beside the podcast. And when you are going to reformat your hard drive you can export your podcast list to a file.

Now I come to the most original BMPx feature – the Jamendo integration. Jamendo allows artists to share their music online for free based on the principal that if you like the music you will later buy it. To get Jamendo started first you will have to download the Jamendo music database onto your hard drive via a menu shortcut; this only takes about thirty seconds. Once you have downloaded themusic database you literally have over 6,000 original virtual albums on your computer. When you play your Jamendo music there only is about a three second delay between you pressing play and the song playing. Due to the fact that most of the artists are relatively new, you will not be able to retrieve any lyrics and artist information. As you start browsing through Jamendo’s large list of artists you’ll be blown away by the amount of good independent music.

I have presented to you the good and the bad of BMPx. The good news is that BMPx is only at version 0.40.13 so it is going to keep on getting better and the few bugs will eventually be eliminated; I’ve only experienced a crash once. There are a few features that I can think of adding, with a radio stream ripper being one of them. Also, BMPx does have an equalizer, so a few equalizer presets would be nice. The lack of not being able to delete favorite radio stations has been addressed in the forums, so that feature should be coming in the next version. Besides these minor issues BMPx is a full featured audio player that cannot be matched in ease of use and functionality by any other piece of software at this current time.
