Streaming to Icecast with roard and RoarAudio PlayList? Daemon (rpld)

This tutorial is to tell you how to setup roard and RoarAudio PlayList? Daemon to stream to a Icecast server. This does not cover installint Icecast itself nor using a diffrent RoarAudio server than roard.

Introduction and Concept

As you may already have noticed the name of RoarAudio PlayList? Daemon (later rpld) contains the word PlayList?. This name is chosen for a simple reason: In fact rpld is not audio player or something like that. It's a playlist manager build on top of the RoarAudio sound system. It does:

  • Handle playlists
  • Push data from files or streams in playlist to the sound server
  • It controls playback by passing control information between clients and sound server

It does not:

  • Play back anything itself
  • Decode or encode audio

However because clients never be in contact with the sound server this may sometimes look a bit like rpld be a full audio player.

As rpld does not handle audio itself setup for streaming is done on roard's end. It is configured to have a so called 'output' to icecast and encoding as Ogg Vorbis.

Installation

Before we can start you need to install the following software:

  • roard from RoarAudio Package
  • rpld
  • rpld-tools
  • vclt-tools

You should also consider to install a nice client for rpld with GUI or something.

If your operating system ships them we suggest you to use those versions and not compile your own binary.

Installing on Debian

Just type as root:

 # apt-get install roaraudio roarplaylistd vclt-tools

Installing from source

Note: This is a very brief description and may or may not be extended later.

First go to http://roaraudio.keep-cool.org/downloads.html and download the packages listed above.

Before you continue you should install the following stuff, too:

  • Essential packages for compiling (compiler, linker, make, system headers,...)
  • libvorbis
  • libshout
  • libuuid (from e2fsprogs)
  • vorbis-tools

Don't forget to install the -dev or -devel packages. Some more libraries are listed in the READMEs for the packages.

For all the packages the building is done like:

 $ tar -xvzf package.tar.gz
 $ cd package
 $ ./configure
 $ make
 # make install

Setting up roard

After installing roard is basically already ready. All we need to tell it is to stream to to our Icecast server.

To do this we need to set the output driver to shout and device name to URL of the server including mount point and login. Such a URL may look like this:

http://source:hackme@streaming-server.example.org:8000/mountpoint.ogg

source is username (this is the default username, do not change if unsure) and hackme is the password.

on Debian

There is a configuration file at /etc/default/roaraudio you need to edit. scroll down to section Audio and Devices. Now set the following parameters:

 ROARD_DRIVER='shout'
 ROARD_DEVICE='http://source:hackme@streaming-server.example.org:8000/mountpoint.ogg'
 ROARD_DRIVER_OPTIONS='sync,codec=ogg_vorbis'

Note that you need to remove the leading #s.

Starting manually

If you start roard manually you must simply pass the parameters using -o, -O and -oO.

Example:

 $ roard -o shout -O http://source:hackme@streaming-server.example.org:8000/mountpoint.ogg -oO sync,codec=ogg_vorbis

Setting up rpld

After you installed rpld the following steps must be done:

  • Set up the store. This is where rpld saves playlists and such.
  • Import some music.
  • Hit play button.
  • Have fun.

Setting up store on Debian

You choose the right system. Store is already set up on Debian.

Setting up store manually and how to start rpld

To set up the store we need to create a directory accessible by the user running rpld. Normally this directory is /var/lib/roarplaylistd/ but you can use a directory within your home directory as well.

First create it. If using /var/lib/roarplaylistd/ we may need to do this as root, if it's located under your home directory just create it with mkdir(1) or how you prefer to create your directorys. If needing to do under root we may also need to set owner back to the user running rpld like this:

 # mkdir /var/lib/roarplaylistd
 # chown YOUR_USER:YOUR_GROUP /var/lib/roarplaylistd

You can get the values for YOUR_USER and YOUR_GROUP using id:

 id

It will list the username under uid and the group name under gid.

Next you need to initialize it. Do this with the following command:

 $ rpld --no-listen --store-path /var/lib/roarplaylistd --no-restore --store

To start rpld run it like this:

 $ rpld --store-path /var/lib/roarplaylistd

You can add a --play to start it in playing state.

Importing some music

To import some music you need a playlist of those music. If you already have some playlist skip next section and continue with Importing a existing playlist.

Generating a new playlist with dir2vclt

To generate a new playlist from a directory you can use the tool dir2vclt. It will generate VCLT? playlist from a directory or single file. Just run it like this:

 $ dir2vclt /some/data/path/with/music/ new-playlist.vclt

Note that dir2vclt currently requires absolute path name.

Importing a existing playlist

To import a existing or just generated playlist you can use the tools rpld-addplaylist and rpld-import or using a GUI you have installed. This document will tell you how to use the former tools.

To create a new playlist use:

 $ rpld-addplaylist 'playlistname'

To import a existing playlist:

 $ rpld-import 'playlistname' 'playlisttype' 'playlistfile'

While playlisttype is the type of the playlist:

VCLT
The playlist format used by dir2vclt. (recommended)
M3U
A common playlist format.
PLAIN
Single filename per line format
Others may also be supported.

Pressing play

To start playback just hit the playback button in the GUI or client you use or use the following command:

 $ rpld-play

Have fun

Now listen to your music and have a lot fun.
