-It contains the following programs:
-
------------
-para_server
------------
-
-para_server streams binary audio data (mp3/oggvorbis/m4a files)
-over local and/or remote networks. It listens on a tcp port and
-accepts commands such as play, stop, pause, next from authenticated
-clients. However, there are many more commands.
-
-It supports three builtin network streaming methods (senders): http, dccp,
-or rtp.
-
- * The http sender is recommended for public streams that can be played
- by any player like mpg123, xmms, itunes, winamp...
-
- * The dccp sender is experimental and requires kernel support for the
- rather new datagram congestion control protocol.
-
- * The ortp sender is recommended for multicast LAN streaming
-
-It is possible to activate more than one sender simultaneously.
-
-The built-in audio file selector of paraslash is used to manage your
-audio files. It maintains statistics on the usage of all available audio
-files such as last played time, and the number of times each file was
-selected.
-
-Its features include
-
- * attributes: Allow fine-grained audio file selection.
-
- * image table. For storage of e.g. album cover art.
-
- * lyrics table. For storage of lyrics.
-
- * playlist table. Stores arbitrary many playlists.
-
- * mood mode. Audio file selection works by specifying mood
- methods involving attributes, pattern matching for file names
- and more. This allows rather sophisticated configurations
- and is explained in more detail in INSTALL.
-
- * rename detection. If files are moved or renamed, afs will
- recognioze them despite of this change.
-
-Despite of all these features, paraslash is lightweight. The
-stripped binary of para_server with all its features compiled in
-mp3/ogg/aac support, http/dccp/ortp support) is about 150K on i386
-under Linux. para_audiod (see below) is even smaller.
-
------------
-para_client
------------
-
-The client program to connect to para_server. paraslash commands
-are sent to para_server and the response is dumped to stdout. This
-can be used by any scripting language to produce user interfaces with
-little programming effort.
-
-All connections between para_server and para_client are encrypted by
-default. For each user of paraslash you must create a public/secret
-key pair for authentication. The (authenticated) connection is encrypted
-with a symmetric rc4 session key.
-
----------
-para_recv
----------
-
-A command line http/dccp/rtp stream grabber. The http mode of this tool
-can be used to receive date from any http streaming source.
-
------------
-para_filter
------------
-
-A filter program that converts from stdin and writes to stdout. It
-is completely independent from the rest of paraslash, so it might be
-useful also for different purposes.
-
-para_filter combines several decoders (mp3, oggvorbis, aac) and a
-volume normalizer New filters can be added easily due to the modular
-design. If more than one filter is specified, the given filters
-are 'piped' together in-memory, i.e. without calling any of the
-read(2)/write(2)/select(2) etc. functions.
-
-----------
-para_write
-----------
-
-A modular audio stream writer. It supports a simple file writer
-output plug-in and optional wav/raw players for alsa (linux-only,
-Debian package: libasound2-dev) and Mac OS. para_write can also be
-used as a stand-alone wav or raw audio player.
-
------------
-para_audiod
------------
-
-The local daemon that collects information from para_server.
-
-It runs on the client side and connects to para_server. The audio stream is
-read from the network and sent through any of paraslash's filters (decoder,
-volume normalizer). The resulting stream is written to an output plug-in
-(writer), e.g. the alsa writer on linux systems. It is possible to capture the
-stream at any position in the filter chain.
-
-para_audiod starts an appropriate receiver, filter and player as soon as
-para_server announces the availability (and the type) of an audio stream.
-Moreover, it listens on a local socket and sends status information about
-para_server and para_audiod to local clients on request.
-
------------
-para_audioc
------------
-
-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
---------
-
-Themable ncurses-based gui. It calls para_audioc and presents
-the obtained information in an ncurses window. para_gui provides
-key-bindings for the most common commands and new key-bindings can
-be added easily.
-
----------
-para_fade
----------
-
-A (Linux-only) alarm clock and volume-fader.
-
----------------
-bash_completion
----------------
-
-A small bash script for inclusion in ~/.bashrc. It gives you command
-line completion for some paraslash commands.
