- para_server (obligatory):
This server listens on a tcp port and accepts commands such as
- play, stop, pause, next. However, there are many more commands.
+ play, stop, pause, next from authenticated clients.
- For audio streaming, at least one sender must be activated.
- At the moment, paraslash contains two internal senders:
+ For audio streaming, at least one of the three supported senders
+ of para_server must be activated:
The http sender is recommended for public streams that can
be played by any player like mpg123, xmms, winamp...
+ The dccp sender is experimental and requires kernel support
+ for the rather new datagram congestion control protocol.
+
The ortp sender is recommended for LAN streaming and for
private streams that require authentication.
All senders have the same set of commands that allow to
control the access permissions of the stream.
- para_server needs an "audio file selector" to work, mainly
+ para_server needs an "audio file selector" to work, mainly
to determine which song to stream next. There are three
selectors available: random, playlist and mysql. The former
chooses audio files randomly and playlist can handle, well,
- para_recv (optional)
- A command line http/ortp stream grabber.
+ A command line http/dccp/rtp stream grabber.
- para_filter (optional)
- An filter program that converts from stdin and writes to
+ A filter program that converts from stdin and writes to
stdout. This one is independent from the rest of paraslash,
so it might be useful also for different purposes.
the given filters are 'piped' together in-memory, i.e. without
calling any of the read(2)/write(2)/select(2) etc. functions.
-- para_play (optional)
+- para_write (obligatory)
- A small wav/raw player for alsa.
+ A modular audio stream writer. It supports a simple file
+ writer output plugin and an optional wav/raw player for alsa.
Debian package: libasound2-dev
- para_audiod (optional, but recommended):
- The local daemon that starts playback and collects information
- from para_server to be forwarded to local clients.
-
- para_audiod reads the audio stream from the network if
- para_server indicates that there is a stream available. It may
- be sent through any of the supported filters (see para_filter
- above) before the result is fed to the output software
- (default: para_play) which must be capable of reading from
- stdin, but is not restricted otherwise.
+ The local daemon that collects information from para_server. It
+ starts an appropriate receiver, filter and player as soon
+ as para_server announces the availability (and the type) of
+ an audio stream. para_audiod listens on a local socket and
+ sends status information about para_server and para_audiod
+ to local clients on request.
- para_audioc (optional, but recommended)
- A small client that can talk to para_audiod. Used to control
- para_audiod and to receive status info. It can also be used to
- grab the stream at any point in the filter chain. para_audioc
- is needed by para_gui, para_sdl_gui and para_krell, see below.
+ The client program which talks with para_audiod. Used to
+ control para_audiod, to receive status info, or to grab the
+ stream at any point in the filter chain.
+
+ para_audioc (hence para_audiod) is needed by para_gui,
+ para_sdl_gui and para_krell, see below.
-- para_gui (optional, but recommended):
+- para_gui (optional):
Themable ncurses-based gui. It calls para_audioc and presents
the obtained information in an ncurses window. para_gui
In any case you need
- gcc, the gnu compiler collection (shipped with distro): gcc-3
- or newer is prefered, but gcc-2.95 is still supported. Note
- that gcc-2.95 may spit out many warnings like unused function
- parameters and missing initializers. These are all harmless
- and may be ignored.
+ or newer is prefered, but gcc-2.95 might still work.
- openssl (needed by server, client): usually shipped with
distro, but you might have to install the "development"
If you want to stream ogg vorbis files you'll need:
- libogg, libvorbis, libvorbisfile, and a command line ogg vorbis
- player, e.g. para_filter or ogg123.
+ decoder, e.g. para_filter or ogg123.
