New:

  • Added support for less memory hungry audio formats, namely pcm_s16 and pcm_f32 (#3008)

  • Added support for native osc library (#2426, #2480).

  • SRT: added support for passphrase, pbkeylen, streamid, added native type for srt sockets with methods, moved stats to socket methods, added socket() method on srt input/outputs (#2556)

  • HLS: Added support for ID3 in-stream metadat (#3154) and custom tags (#2898).

  • Added video.align.

  • Added string.index.

  • Added support for ffmpeg decoder parameters to allow decoding of raw PCM stream and file (#3066)

  • Added support for unit interactive variables: those call a handler when their value is set.

  • Added support for id3v2 v2.2.0 frames and pictures.

  • Added track.audio.defer to be used to buffer large amount of audio data (#3136)

  • Added runtime.locale.force to force the system's locale (#3231)

  • Added support for customizable, optimized jemalloc memory allocator (#3170)

  • Added source.drop to animate a source as fast as possible..

  • Added in house replaygain computation:

    • source.replaygain.compute to compute replaygain of a source

    • file.replaygain to compute the replaygain of a file

  • Added support for ImageLib to decode images.

  • Added support for completion in emacs based on company (#2652).

  • Added syntactic sugar for record spread: let {foo, gni, ..y} = x and y = { foo = 123, gni = "aabb", ...x} (#2737)

  • Added file.{copy, move} (#2771)

  • Detect functions defining multiple arguments with the same label (#2823).

  • Added null.map.

  • References of type 'a are now objects of type (()->'a).{set : ('a) -> unit}. This means that you should use x() instead of !x in order to get the value of a reference. Setting a reference can be done both by x.set(v) and x := v, which is still supported as a notation (#2881).

  • Added ref.make and ref.map.

  • Added video.board, video.graph, video.info (#2886).

  • Added string.getter.single (#3125).

Changed:

  • Switched to dune for building the binary and libraries.

  • Changed cry to be a required dependency.

  • Changed default character encoding in output.harbor, output.icecast output.shoutcast to UTF-8 (#2704)

  • BREAKING: all timeout settings and parameters are now float values and in seconds (#2809)

  • BREAKING: in output.{shoutcast,icecast}:

    • Old icy_metadata renamed to send_icy_metadata and changed to a nullable bool. null means guess.

    • New icy_metadata now returns a list of metadata to send with ICY updates.

    • Added icy_song argument to generate default "song" metadata for ICY updates. Defaults to <artist> - <title> when available, otherwise artist or title if available, otherwise null, meaning don't add the metadata.

    • Cleanup, removed parameters that were irrelevant to each operator, i.e. icy_id in output.icecast and etc.

    • Make mount mandatory and name nullable. Use mount as name when name is null.

  • reopen_on_error and reopen_on_metadata in output.file and related operators are now callbacks to allow dynamic handling.

  • Reimplemented harbor http handler API to be more flexible. Added a new node/express-like registration and middleware API (#2599).

  • Switched default persistence for cross and fade-related overrides to follow documented behavior. By default, "liq_fade_out", "liq_fade_skip", "liq_fade_in", "liq_cross_duration" and "liq_fade_type" now all reset on new tracks. Use persist_overrides to revert to previous behavior (persist_override for cross/crossfade) (#2488).

  • Allow running as root by default when docker container can be detected using the presence of a /.dockerenv file.

  • id3v2 argument of %mp3 encoder changed to "none" or version number to allow to choose the metadata version. true is still accepted and defaults to version 3. Switched to our internal implementation so that it does not require taglib anymore.

  • Moved HLS outputs stream info as optional methods on their respective encoder.

  • Changed self_sync in input.ffmpeg to be a boolean getter, changed self_sync in input.http to be a nullable boolean getter. Set self_sync to true in input.http when an icecast or shoutcast server can be detected.

  • Add sorted option to file.ls.

  • Add buffer_length method to input.external.rawaudio and input.external.wav (#2612).

  • Added full OCaml backtrace as trace to runtime errors returned from OCaml code.

  • Return a nullable float in request.duration.

  • Removed --list-plugins-json and --list-plugins-xml options.

  • Added --list-functions-json option.

  • Removed built-in use of strftime conversions in output filenames, replaced by an explicit call to time.string (#2593)

  • Added nullable default to {int,float,bool}_of_string conversion functions, raise an exception if conversion fails and no default is given.

  • Deprecated string_of in favor of string (#2700).

  • Deprecated string_of_float in favor of string.float (#2700).

  • Added settings.protocol.youtube_dl.timeout to specify timeout when using youtube-dl protocol (#2827). Use yt-dlp as default binary for the protocol.

Finally, the 1.0.0 release! It brings several important fixes, but also some nice novelties. The most outstanding difference concerns output.icecast(): its restart and restart_delay parameters are gone, replaced by a new on_stop handler which is called on every error (failed connection or disconnection) and returns the new restart delay. The on_error handler receives a string describing the error which enables user-friendly reporting, adaptative delays, etc. Note that on_error defaults to fun(_)->3. which is equivalent to having restart=true, restart_delay=3. in previous versions, NOT the same as the former restart=false default. As a result, liquidsoap won't fail to startup if an initial connection attempt fails.

Fixes:

  • LS-532,527: avoid freeze after errors in streaming threads or source initialization routines

  • LS-542: race condition in playlist*() breaking randomness

  • LS-489: double expiration lead to illegal queue length and freeze of request-based sources

  • Avoid multiple simultaneous reloading in playlist*(), thanks to Fabio Costa for his help on this one!

  • Pass charset information to icecast server to avoid encoding bugs

  • LS-555: timeout for icecast connection attempts

  • LS-559: permanent stop after disconnection on Ogg streams

  • LS-565: efficient and crash-free error handling in input.http/harbor() when the input stream has an invalid number of channels

  • LS-431: proper handling of duration in blank() avoids abusive empty tracks

  • LS-556: rework conversion operators, optimizations used to be unsafe & broken

  • LS-574: silent MIDI synthesis operators

  • LS-396: drop*()'s types reflect that they don't support variable arities

  • LS-442: allow comments not terminated by newline at end of file New:

  • on_error handler in output.icecast(), see above

  • New msg param in %mp3 for marking frame headers, defaults to version string

  • output.file(): new on_close parameter, may be used to write exact duration

  • delay() now has an "initial" parameter

  • LS-557: "server.timeout" setting can now be disabled by setting it to -1

  • LS-532: source.init() for selective init with a way to handle errors, plus settings "clock.allow_streaming_errors" and "init.force_stat" (or --force-start on the command line) for easing dynamic uses of liquidsoap Enhancements:

  • Panic crash to avoid frozen liquidsoap after duppy crashes

  • Text-to-speech: festival and sox are now only runtime dependencies

  • Fix: deadlock when disconnecting harbor users through server/telnet command.

  • Fix: dynlink detection in native mode with old versions of ocaml

  • Fix: playlist.safe() was unusable in beta2, as a side effect of removing duplicate "timeout" parameter in playlist().

This release introduces lots of fixes and cleanup, but also some new features. Major novelties: support for fast seeking and cue points, FLAC and improved AAC+ support, introduction of the liquidsoap yellowpages "flows", plugin support and improved messages for scripting errors Compatibility warning: insert_metadata has changed, and clock.assign_new() should be used instead of clock() to avoid some of the new static checks

Decoders:

  • New support for seeking and fast computation of durations in most formats

  • New decoders: FLAC (native & Ogg) and images using Camlimages

  • Fixes in Ogg decoding: LS-515 (loss of data) and LS-537 (segfault).

  • Fix LS-337: periodical failures when decoding AAC(+) streams

  • AAC(+): use new ocaml-faad with builtin mp4ff, easier to build

  • New detection mechanism mixing extensions and MIME types (when available), with corresponding settings decoder.file_extensions.<format> and decoder.mime_types.<format>.

  • Fix segfaults with ocaml-aacplus

  • Enhancement LS-441: filter metadata before encoding, based on the "encoder.metadata.export" setting.

  • Rework infrastructure of encoded outputs to fit all formats, outputs and styles of metadata handling, file reopening (#386)

Harbor:

  • New: output.harbor() which acts as a mini icecast server, accepting listeners directly. Encoding is shared among users, and is only performed when needed.

  • New: ability to register HTTP GET/POST handlers to create simpler web services, using harbor.http.register/remove().

  • Make all settings local: port, user and password can be set independently for each input.harbor() source

  • New: "metadata_charset" and "icy_metadata_charset" in input.harbor()

  • Fix: race condition possibly leading to abusive "source taken" (LS-500)

Icecast:

  • Add support for streaming native flac, only works when streaming to input.harbor(), not supported by actual Icecast servers

  • Restore output.pipe.external(), now called output.external()

  • New parameters for most outputs and inputs (start, on_start, on_stop, fallible); cleanup and uniformize implementations (LS-365)

  • New ALSA settings alsa.alsa_buffer, alsa.buffer_length and alsa.periods Setting periods=0 allows to not attempt to set the number periods, which is impossible on some devices

  • New preference order in input/output.preferred(): pulseaudio, portaudio, oss, alsa, ao, dummy

Operators:

  • New: support for cue points with cue_cut()

  • Change insert.metadata() which is now more script friendly, returning an insertion function rather than register a server command. The old functionality is available as server.insert_metadata().

  • New: rms() operator for getting RMS of a stream, and server.rms() which makes this information available as a server command.

  • New: track_sensitive mode for blank detection operators

  • New: playlist.reloadable() for playing a list once, with a command for restarting it.

  • Fixed double registration of server commands which resulted in broken "help" command (LS-521)

Script language:

  • Option "-i" doesn't show types for pervasives anymore

  • Pretty printing of types (LS-474) with indentation, also used in the documentation

  • Enhanced type errors (LS-459): no more traces, only the relevant part of types is displayed, plus a few special friendly messages.

  • Enhanced static checks (LS-123) thanks to the introduction of the active_source subtype, for unused variables and ignored values This should avoid common errors, help troubleshooting If needed, advanced users can work around errors using --check-lib and --errors-as-warnings

General:

  • Do not attempt to install "daemon" files if user/group have not been set, unless forced using "make INSTALL_DAEMON= install"

  • Fix several core "source protocol" bugs, causing assert failures and other crashes: LS-460 (source becomes not ready without operator knowing) #403 (information about being ready is not precise enough)

  • Fix incorrect image accesses (LS-430) by introducing a safer VFrame API Applies to most video operators ( video.fade(), video.text(), effects...)

  • Cleanup resource (de)allocation, which is becoming critical with dynamic reconfigurations (e.g., dynamic output creation, source.dynamic()) Enforce that server commands are always deallocated (LS-495) Attempt to stop sources when initialization fails, so they cleanup as much as possible (LS-503) Avoid deadlocks upon crashes in IoRing-based operators Share code for stoppable feeding threads, use it in input.harbor() Avoid useless initialization of SDL systems

  • Dynamic loading of lame and aacplus libraries, making it possible to ship them as separate binary packages. This is particularly useless for non-free libraries and for those that depend on X (e.g., SDL) which is often undesirable on servers

  • Support for separate compilation of most optional features as plugins Use --enable-<feature>-dynamic-plugin in ./configure and --dynamic-plugins-dir in liquidsoap

  • Better Win32 support, more version checks, separate compilation of C files and compliance with Debian's OCaml standards

  • Externalize many audio and video functions in the new ocaml-mm library Factorize and optimize various conversions

  • Rewrite harbor and server code using the new Duppy monad, introducing camlp4 into the build system

  • Fix: properly escape filenames in external file duration methods

This beta version introduces two major new features: heterogeneous stream types and clocks.

New:

  • Different sources can carry different types of content.

  • Encoding formats have been introduced to help infer stream content types. This brings static checking for bounds in encoding parameters.

  • Introduce conversions between stream contents (mono, stereo, drop audio, video, etc) and muxing.

  • Allow explicit type annotations in scripts.

  • Introduce clocks, cleanly allowing for the coexistence of different time flows, and avoiding inconsistencies that can result from it. Soundcard I/O and cross-based operators notably make use of it.

  • Remove root.sync, replaced by attaching a source s to clock(sync=false,s).

  • Enable dynamic source creation and source.shutdown().

  • Extend and adapt MIDI and video operators.

  • Introduce purely metadata streams (audio=video=midi=0 channels) and metadata stream decoder.

  • Support WAV streams in input.http/harbor().

  • Introduce static image decoder using SDL image.

  • Remove bound of request identifies (RID).

  • Experimental: source.dynamic() for advanced dangerous hacking.

  • Make path relative to script in %include "PATH", and introduce %include <...> where path is relative to liquidsoap library directory.

  • Add channels_matrix parameter to output.ao().

  • Add on_(dis)connect hooks in input.harbor().

Cleanup and fixes:

  • Lots of cleanup and fixes as with all major code rewriting.

  • Optimize video and stabilize it a little bit... still not perfect.

  • Rewrite stream and file decoding API, as well as file format detection.

  • Enhance shutdown and error message reporting, notably for icecast and request-based sources.

This release is a bugfix of the latest snapshot (0.9.2). It will be the last bugfix before 1.0.

Bugs fixed:

  • Add "audio/mpegurl" to the list of mime-type for basic playlist parsing.

  • Decode arguments passed to input.harbor.

  • Use Camomile framework to try to recode arguments and user/password passed to input.harbor.

  • Support Theora 1.1 API via ocaml-theora 0.2.0.

  • Fixed input.lastfm.

  • Fixed SDL output.

This release is a SNAPSHOT of upcoming features. It also contains several important bugfixes. As a snapshot, it contains experimental or unpolished features, and also breaks compatibility with previous versions. You should in particular notice the two "New" items below:

  • random(strict=true) is now called rotate();

  • request sources (playlists, request.*) have a new queuing behavior, check the doc (request-sources.html) or revert to conservative=true.

Bugs fixed:

  • Ogg encoder now muxes pages according to their ending time.

  • Support "ogg/audio" and "ogg/video" mime types for HTTP ogg streams.

  • Changed external encoder's "restart_encoder" to the more relevant "restart_on_new_track". Added optional "restart_after_delay" to restart the encoder after some delay. Also completely rewrite stop mechanism. Stop operation now waits for the encoding process to finish, allowing proper restart_on_new_track like for ogg encoded data.

  • Factorized buffered I/O code. Also added a blocking API, which avoids "no available frame" and "reader not ready" messages and audio glitches. It enforces that root.sync be deactivated for these sources, such that synchronization is done by the source. (#203)

  • Factorized file decoding code.

  • Fixed reversed order when parsing playlists using playlist.parse().

  • Avoid bad crashes when resources lack, e.g. no more memory.

  • Tighten and enforce the inter-source protocol.

  • All outputs: fix the autostart server command. With the former code, a modification of the autostart parameter was only taken into account one start/stop cycle later.

  • on_blank(): fix a bug that prevented the first call to on_noise.

  • Fixed estimated remaining samples on ogg files, fixes issues with operators relying on this value, in particular crossfade() and request-based sources when operating in non-conservative mode.

  • Fixed socket descriptor leak in input.http. (#318)

  • Fixed deadlock at init when an exception was raised at wake_up phase. (#319)

  • Fix delay() which could sometimes incorrectly declare itself ready, and thus try to get some data from its unavailable input source.

  • Bug in queue duration estimation led to infinite feeding of the queue, until all request IDs are taken.

  • Several fixes enforcing clean (non-deadlocking) sleep/shutdown.

New:

  • The operator rotate() replaces random(strict=true), and random() does not have a strict parameter anymore.

  • Switch to new behaviour in request-based sources. Use conservative=true to get to the old behaviour.

  • on_blank(): provide an on_noise handler.

  • playlist*(): add server commands for reloading the playlist and changing its URI.

  • Fallible outputs: all outputs now have a fallible mode, in which they accept fallible sources, and automatically start/stop when the child fails to stream.

  • EXPERIMENTAL ogg/dirac encoding support.

  • output.*.aacplus(): native outputs encoding in AAC+ using ocaml-aacplus.

  • Switched to a custom implementation of the various shout protocols. It notably allows arbitrary content-type settings which enables AAC+ streaming. Enabled wrappers for external encoders for AAC+ format aacplusenc (#220 and #136). Also added custom IRC, AIM and ICQ headers to shoutcast wrappers (#192).

  • Harbor now supports Shoutcast/ICY headers properly. This allows in particular the use of any supported data format for the source client.

  • Harbor sources now also consider "song" field when updating metadata.

  • Added built-in support for m4a audio files and metadata. Made external support optional through enable_faad.

  • Added optional resampling for output.external operators (#273).

  • Added optional host and port parameters for audioscrobbling submissions. Allows to use alternate systems, such as libre.fm of jamendo's compatibility API. Added nowplaying submission, and various wrappers, including a full submission process (now playing at beginning, submit some times before the end).

  • New variables in the script language: liquidsoap.version and configure.{libdir,pidfile,logdir}.

  • Added built-in support for replay_gain, through the replay_gain protocol (enabled by default) and the replay gain metadata resolver (to be enabled using enable_replaygain_metadata()). (#103 & #317)

  • Reverse DNS operations can be disabled using settings keys server.telnet.reverse_dns and harbor.reverse_dns.

Experimental:

  • MIDI: file decoding, synthesis, virtual keyboard.

Removed:

  • RTP input and output.

Bugs fixed:

  • Fixed request task not ending properly for request-driven sources (playlist, request.queue, request.equeue). Fixes a problem reported when reloading an empty playlist multiple times. (#269)

  • Fixed math.h usage in rgb_c.c.

  • Fixed append operator. (#284)

  • Fixed OSS compilation for non-linux systems.

  • Disconnect idle harbor sources after timeout has expired. Thanks to Roman Savrulin for reporting and fixing !

  • Fixed liGuidsoap to use the (not so) new metadata field initial_uri.

  • Fix bugs in the life cycle (sleep/wake_up) of queued request sources, which made say_metadata unfunctional.

  • Remove buggy unbuffered {input,output}.jack. (#231)

  • Fixed audio information sent to icecast. (#226)

  • Fixed global reset starting inactive sources. (#227)

  • Fixed shoutcast source initial answer in harbor. (#254)

  • Fixed frame and metadata duplication in cross operators. (#257)

  • Fixed several sources (outputs, external streams) that were not going to sleep correctly.

  • Fixed shutdown function. Fixes #153

  • Fixed input.oss. Liquidsoap now works with OSS4 ! Fixes #158

New:

  • Added a hook to execute a function when playlist.once ends

  • Enhanced smart_crossfade

  • Added string.case and string.capitalize

  • New "exec_at" operator, to execute a function depending on a given predicate

  • Added script example in the documentation to listen to radio Nova and get the metadata from a web page.

  • Added "primary_queue" and "secondary_queue" commands to request.queue and request.equeue sources. Also set the metadata "queue" to either "primary" or "secondary" for each request in the queue. Documented it too.

  • Insert latest metadata for a node of a switch source when switching back to it in a middle of a track.

  • Added a 'conservative' parameter to cross, smilar to the one in smartcross.

Internal:

Bugs fixed:

  • Now works on FreeBSD and hopefully other unices that are stricter than Linux about Mutex usage.

  • input.http() now has a bind_address parameter.

  • Harbor socket now has a timeout for lost connections.

  • smartcross() is now more compliant with the inter-sources protocol, fixes several "get frame didn't change the buffer" bugs.

  • Ogg packeting bugs.

  • Buffering policy in input.http/harbor().

  • No "." in IDs and labels.

  • Resources: FD leaks, useless threads (threads leaks?) in input.http().

  • fade.out() used to run into infinite loops when the delay was 0.

New:

  • New documentation system and website.

  • Self-documenting server with a more helpful "help" command.

  • Moved to duppy: less threads, lighter load, and an configurable scheduler.

  • Moved to Taglib for more reliable access to MP3 metadata.

  • MIME types, notably for playlists and MP3 files.

  • New Jack support. The old one has been renamed to in/output.jack.legacy().

  • Harbor: per-mount passwords and the stop command to kick a source client.

  • Official Last.FM client.

  • Metadata is no more punctual but interval-based, which suppresses some surprising behaviours.

  • Perfected daemon behaviour.

  • All output.file.*() now have the features that used to be only in output.file.vorbis(), notable re-opening. Added %w to the strftime-like format codes allowed in their filename parameter.

  • Add clear_metadata() and map_metadata(). Now, rewrite_metadata() is a simple specialization of map_metadata(), written in utils.liq.

  • Dynamic amplification factor in amplify(), e.g. useful for replay gain.

  • Lots of new functions in the scripting API: for lists, requests, system interaction, shutdown, command-line parsing, scripted server commands, etc.

As always:

Bugfix release:

  • Close Http socket

  • Add http socket timeout

  • Close playlist file after reading its content

  • Fix http redirect support for lastfm files

  • Fix file open leak in camomile support

Bugfix release:

  • Fixed #57: scpls and mpegurl playlist parsing

Notation: "-" stands for a change, "+" for an addition.

  • Language

    • Support for polymorphism, subtyping and basic ad-hoc polymorphism, which allows a much simpler API, notably for maths and serialization.

    • Added interactive_*() for mutable values.

    • The right syntax for settings is now set("var", value) and can be used anywhere in the scripts.

    • The volume parameters of most operators are now in dB.

    • Many builtin functions added.

    • Nicer type error messages.

  • Sources

    • Added input.lastfm() to relay last.fm streams.

    • Added input.harbor() to received Icecast2 source streams.

    • Added noise() to generate white noise

    • Reimplemented playlist support, added various xml and text formats.

    • Added mpd protocol to find files using mpd.

  • Operators

    • New effects: compress(), flanger(), pan().

    • New filters: filter.fir.*(), filter.iir.*(), filter.biquad.*(), comb().

    • Added support for LADSPA effects.

    • Added eat_blank() to remove blanks.

  • Outputs

    • Added non-default restart option for output.icecast.*().

    • Added the possibility to tweak some settings at runtime.

    • Split output.icecast.vorbis() into output.icecast.vorbis.*() to distinguish between encoding modes -- and similarly for output.file.vorbis and mp3.

    • Better handling of Icecast disconnections.

  • IO

    • Added portaudio support.

    • Jack support is now somewhat working.

  • Major cleanup of the core stream representation; moved to float arrays, removing several back-and-forth conversions and enhancing the perfs a lot; reviewed all sources and operators, made many minor enhancements btw.

  • Lots of sound processing operators: compand, compress, normalize, pitch, bpm, soundtouch, saw, square, etc. Add more shapes to fade.*().

  • New track processing operators: insert_metadata, on_track.

  • Smart cross: allows to select a transition based on the volumes around the end-of-track.

  • Support for AAC encoding/decoding.

  • Several fixes to output.icecast.mp3 in order to support shoutcast servers.

  • Automatic format recognition for input.http(), support for playlists.

  • OSS I/O.

  • Unbuffered ALSA I/O for low latency.

  • Server interface via UNIX domain sockets.

  • Better output.file.vorbis with support for re-opening the file, appending, interpolate strftime format codes, etc.

  • Add pre-processing and math primitives to the language, new _[_] notation for assoc(), ruby-style anti-quotation ("..#{..}.."), add_timeout(), execute(), log()...

  • Ability to tweak the internal PCM stream format.

  • Classify sources and operators in categories for more structured doc.

  • Started a few visualization operators, text and graphics based.

  • New portable output to speakers using libao().

  • Updated liGuidsoap to use it until ALSA gets enhanced.

  • Implemented a decent estimation of the remaining time in a track.

  • Added the cross() operator allowing cross-fading.

  • Generalized say_metadata() into append() and prepend().

  • Per-track settings for cross(), fade.*(), prepend() and append() using requests' metadatas.

  • Implemented input.http.mp3(), including support for icy metadata.

  • New pipe() operator which allows one to filter the raw audio through an external program. However, sox and other common tools aren't suitable for that because they don't flush their output often enough.

  • New on_blank() operator for calling a callback on excessive blanks.

  • Restart outputs on insane latencies.

  • Type checkings for settings.

  • Setting for not starting the internal telnet server.

  • Now handles old and new versions of Camomile correctly.

  • More standards-compliant tarball

  • Generate doc with locally built liquidsoap

  • Try to cope with ill-formed mp3

  • Updated for newer versions of Camomile

  • Many minor and major fixes at every level!

  • Conversion of metadata to UTF8.

  • Got rid of too many threads by scheduling all download tasks in a single thread, and handling all of the server's clients in another single thread.

  • Simplified the time interval syntax and integrated it to the script language.

  • New protocol: Wget for FTP, HTTP and HTTPS.

  • Ability to define a new protocol from the script, typically using an external app/script for resolution, such as bubble.

  • Ability to use an external app/script for dynamically creating requests.

  • New on_metadata operator for performing arbitrary actions (typically a call to an external script) when metadata packets occur in a stream.

  • MP3 encoding, to file or shout.

  • API renamings and simplification.

  • Supports transition, as functions of type (source,source) -> source in all switching operators: schedule, random, fallback.

  • Restart icecast2 outputs on failures.

  • Major changes to the scripting language which is more uniform and flexible, has functions, a helpful (?) type inference, and a simple Ruby-like syntax.

  • Timing constraints and synchronization are managed by Root in a centralized way, no more by the many outputs which need it.

  • Audio decoding is no more based on file extensions, but on the existence of a valid decoder.

  • Added the equeue operators which allows interactive building of playlists, supporting insertion and moving of queued requests -- queue only allows you to push requests and cancel queued requests.

  • A Python-Gtk GUI for controlling operators, or more specifically as a console for creating your live show -- to be updated, still unstable.

  • Alsa input and output.

  • Blank detection, automatically skips on too long blanks, or strip them.

  • Http ogg/vorbis relay, the way to relay live shows.

  • Interactive mixer.

  • The request system was mostly rewritten to really fulfill its specification.

  • The server is no more associated to the queue operator but is now something external, in which all operators can plug commands. This much more logical design lead to many more interactive controls. The syntax of command outputs was also simplified for easier automated processing.

  • Dynamic loading of plugins.

  • Release for academic demonstration, not functional.
