Features ======== configurable audio streaming software ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ para_server streams binary audio data (mp3/ogg files) over local or remote networks. It contains two built-in streamers: the http streamer and the ortp streamer. para_audiod runs on the client side and connects to para_server. The audio stream is read back and sent through any of paraslash's filters (mp3 decoder, ogg vorbis decoder, volume normalizer,...) and the resulting stream is written to an external program's standard in, usually an audio player, like para_play that uses alsa. It is possible to grab the stream at any position in the filter chain. The receiving/filtering software is also available as standalone command line tool: para_recv grabs the http or ortp stream and writes to stdout; para_filter reads from stdin, converts the stream according to the given --filter command line options and writes the transformed stream to stdout. configurable audio file selectors: ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ There are three audio file selectors (aka "database tools") available: - random - plm (playlist manager) - mysql The first two of these are rather simple, and they are always supported. They allow streaming of randomly selected files or files given by a playlist respectively. The (optional) mysql selector is more involved. It manages statistics on your audio files and audio file selection is done by sending a user-defined sql-query to the mysql server. This allows rather sophisticated configurations and is explained in detail in README.mysql. It is possible to switch between all supported selectors at any time. small memory footprint: ~~~~~~~~~~~~~~~~~~~~~~~ paraslash is lightweight. The stripped binary of para_server with all its features compiled in (mysql/random dbtool, mp3/ogg support, http/ortp support) is about 110K on i386 under Linux. para_audiod is even smaller. command line interface, including shell: ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ para_client without arguments starts interactive (shell) mode. Otherwise, command is sent to para_server directly and output is dumped to stdout. This can be used by any scripting language to produce user interfaces with very little programming effort. authentication/encryption via openssl: ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 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/encryption. various user interfaces and utilities: ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ o para_gui. Curses based interface, displays information in a curses window and can be used to easily control para_server and para_audiod. o para_sdl_gui. Shows pictures (on a per song basis) and other information about the current audio file. Can be used as a screen saver. o para_krell. A gkrellm2 plugin that shows small pics and is able to launch 27 different commands by clicking on the image. o para_slider. User-friendly stream creator for people who don't like their keyboard. o para_dbadm. Simple curses interface for changing attributes. o para_fade. Simple volume fader and alarm clock.
