See the user manual for details. ------------ -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 built-in 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 requires kernel support for the 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 storing e.g. album cover art. - - * lyrics table. For storing lyrics. - - * playlist table. Stores arbitrary many playlists for later use. - - * 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 -<< - README.afs ->> - - * rename detection. If files are moved or renamed, afs will - recognize 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 160K 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 -RSA key pair for authentication. The authenticated connection is -encrypted with a symmetric rc4 session key. - ---------- -para_recv ---------- - -A command line http/dccp/ortp stream grabber. The http mode of this -tool can be used to receive data from any http streaming source. - ------------ -para_filter ------------ - -A filter program that converts from stdin and writes to stdout. - -para_filter combines several decoders (mp3, oggvorbis, aac) and a -volume normalizer. New filters can be added easily. It is possible -to "chain" any number of filters, like UNIX pipes. - -para_filter does not depend on other parts of paraslash, so it can -be used as a stand-alone command line tool for audio decoding and -volume normalization. - ----------- -para_write ----------- - -A modular audio stream writer. It supports a simple file writer -output plug-in and optional wav/raw players for ALSA (Linux) and for -coreaudio (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. As soon as -para_server announces the availability of an audio stream, para_audiod -starts an appropriate receiver, any number of filters and a paraslash -writer to play the stream. It is possible to capture the stream at -any position in the filter chain. - -Moreover, para_audiod listens on a local socket and sends status -information about para_server and para_audiod to local clients on -request. Access via this local socket may be restricted by using Unix -socket credentials, if available. - ------------ -para_audioc ------------ - -The client program which talks to 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 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. ------- LICENSE
