Icecast 2.3.2 ----------------------------------------------------------------------------- - Character set support. Most non-Ogg streams (eg MP3) send metadata as Latin1 but it could be in other character sets. As icecast uses UTF-8, we need to convert to UTF-8 so that web pages and stream directories render correctly, . Allow a per-mount setting. For when source clients do not indicate which character set is in use. . a charset= parameter to the metadata request. . Default for non-Ogg content is now Latin-1 (aka ISO-8859-1), Ogg content still use UTF-8. - Authentication . Each mountpoint authentication is isolated so one mount authentication does not slow another mountpoint authentication down. . XSL pages can require authentication. . Add some sanity checks for incorrect settings. - Listening socket update . Allow multiple ports to be allocated which allow multiple shoutcast source clients to stream on the same icecast instance. . No internal limit on the number of listen-sockets that can be used. . Allow for a listen-socket to be marked SSL capable. While any client could connect on these, the idea is really for /admin requests. . allow for a to bind to ipv4 and ipv6. BSDs may require to the use of bind-address. - XSL update . XSL pages include an xspf link for non-auth streams. . XSL pages in both webroot and adminroot can take a mount= arg to limit which stats are transformed. . XSL files can specify the content-type to return to the client. It is no longer fixed to html - Updates for stream directory handling. . A stream is not registered with the directory until after the first minute has passed. some streams have been stuck in a connect/disconnect loop. . Increase retry time on failure, if the stream add is rejected then it will be down to a misconfiguration so a long retry delay is performed. . A YP server that is not responding is ignored for a while - Updates for Win32 . Build cleanups, . Newer versions of dependency libs (libxml2/libxslt/libcurl etc) . buffer overflow fixes when many streams are active - Accept/Ban IP support. Now takes filenames for explicitly accepting or denying requests from specified IP addresses. Useful in cases where firewall access is not available. The files, if defined, are re-read automatically if updated. - A Mountpoint is exported to the slaves even if no mount section is defined for it. You can still use the hidden setting to prevent that from happening. - Relays handle redirection (HTTP 302) if one is received at startup. - Automatically generate XSPF playlist like we do with M3U, the mountpoint extension is .xspf - Header updates for proxy handling and certain clients like some shoutcast source clients and flash players. - Added Kate/Skeleton codecs to Ogg handler. - Various stats cleanups. Added some global stats (server ID, email contact etc). - Documentation updates. - The streamlist passed from master to slave had a limited length, so if there were many streams then some could of been left out. - Relay startup/shutdown is cleaner. - several build cleanups. - several resource leaks and race conditions fixed Icecast 2.3.1 ----------------------------------------------------------------------------- - new tag in state the trigger size (in KB) for cycling the log files. - new tag in enable (1) if you want to use a timestamp for an extension when cycling logs. - Handling of certain shoutcast source clients is fixed, this typically affected NSV source clients - A race in source shutdown when listeners are authenticated could lead to server crash - An audio glitch was possible in playback of vorbis streams when a new logical stream started (eg metadata update). - stats speedup. Processing large numbers of stats was slow. Typically only seen when using lots of streams on the same server. - 404 responses were being sent back in some places, now 403 is sent back. - Auth URL now handles the authentication to scripts better. The order in which username/password are selected is 1. url is http://user:pass@host:port/.... 2. and 3. with listener_add/remove, listener supplied username/password is used. - A streams intro file can now be changed, using HUP, on active streams. - mount without a name crashed the server - Various documentation updates Icecast 2.3 ----------------------------------------------------------------------------- **** New features for 2.3.0 **** - Streaming support for ogg speex, ogg flac, ogg midi - intro file support - per mount settable Intro files will play when a listener first connects to a stream. This is designed for station jingles and the like. If you don't broadcast in ogg vorbis, you must make sure the bitrate/samplerate/number of channels match up to your stream. - on-demand relays, global and per-relay settable On demand relays only connect to the relayed content when there are listeners attached to the relay. This can save bandwidth in certain cases. - fallback to file, extends on the intro file handling. With this feature, you can specify a "fallback file" which will be played in a loop and sent your currently connected listeners in the event of a source client disconnect. This means your listeners stay connected while you fix your disconnect problem. Same rules regarding bitrate/samplerate/ number of channels apply as with intro files. - new mount-level settings 1. public, type/subtype, genre settings, stream description, stream url, stream name, bitrate (override what is sent from the source client) 2. mp3 metadata interval 3. on-[dis]connect scripts can be stated per-mount, invoked at source start/stop and take 1 arg which is the mountpoint. - New URL listener authenticator. This delegates your listener authorization to an external application. URL calls are made on listener connect/disconnect as well as source connect/disconnect. It is meant for large broadcasters who have existing authentication systems that need to be integrated into. Included is an example php-based application that can be used in conjunction with the url authenticator to manage a simple subscription-based broadcast. - HTPasswd authenticator uses in-memory structures now. - On demand files now can be fed through an authenticator - Update to admin/web xslt interface - Icecast can now be installed as a win32 service **** Fixes for 2.3.0 **** - real/helix works - win32 access log correct - stats client is stable now (curl -X STATS http://admin@host:port/) - show mountpoints on stats that are inactive but have an active fallback - more updates over HUP possible - improved stability under heavy load - moving clients will no longer sometimes deadlock the server - avoid small writes to reduce TCP overhead. Icecast 2.2 ----------------------------------------------------------------------------- ****New features for 2.2 (in no particular order):**** - Theora Video support - Icecast now supports video streaming via theora. Currently, we require the latest (alpha 4) version of libtheora. This is an optional compile, so if you don't have theora then icecast will safely ignore it - Shoutcast style source client support - Icecast now supports the connection protocol used by the Shoutcast DSP source client. This is the same connection protocol used by their NSV encoding tools. This means that not only can you use the Shoutcast DSP to stream to icecast, but that you can also stream NSV via their tools. - AAC is added as a supported streaming format - Not too many source clients support streaming in this format, but we support it. - Cluster password - Now you can specify a cluster password as a option in the config. This will allow you to cluster multiple servers/mounts into a single listing on the stream directory. Note that this is different than "grouping" which groups together streams coming from the same physical IP and with the same stream name. Clusters are meant for relays of the same stream and will only be listed *once* in the stream directory. When a listener tunes into a cluster, they will be served an m3u file with all the clusters for that stream. - Playlist Log - This is an option setting that will create an audit trail of metadata that comes through icecast. It is a single file that contains information for all mountpoints. - Range Support for static files - We now support seeking in files served off the icecast fserve. - Metadata Update via Admin - We now support metadata updates via the admin interface for both MP3 AND Ogg Vorbis streams. - Per mount hidden stats and YP prevention - You many now indicate certains mounts to be excluded (i.e. hidden) from the main status.xsl page. This is useful when using local private relays. You can also override the YP setting (as in disable) on a per-mount basis. Also useful for local private relays. - Multiple example config files - We now have multiple config files for you to use as a base. A "simple" one for quick-start, and a more detailed "advanced" one with all the features, as well as a "shoutcast compatable" one, which shows how you'd config for using the shoutcast DSP. - Relay user/pass - You can now specify authentication used by a relay. This is for the case where you have listener authentication enabled for a mountpoint, and want to connect a relay to it. Icecast 2.1 11/04/2004 ----------------------------------------------------------------------------- ****New features for 2.1 (in no particular order):**** -Listener Authentication- Icecast now supports listener authentication. This provides a mechanism for creating/maintaining users and passwords for listeners. Currently, we only have implemented a simple, file-based storage for users and passwords. New authenticators are on the horizon (such as URL-based or possibly MySQL based) New admin pages were also added for the maintenance of users/passwords. Please check the docs for a more detailed description of this new feature. -Multi-Level Fallbacks- Multi-level fallbacks allow for specifications of a series of fallback mounts that you can use to automatically move listeners in the event of a source being disconnected. In the event of new listeners attaching to the source stream that has been disconnected, they are routed to the fallback mount (if specified). Icecast now has fallback-override capability as well which means that in the event of a source stream failure, listeners are moved to the fallback mount, and then automatically recaptured when the original source stream returns. -Burst-On-Connect- This is an new, optional config setting which will send a initial burst of data to connecting listeners. This has the effect of reducing (significantly) the startup buffer latency from the end-user perspective. This option is enabled by default. ****New Enhancements for 2.1**** -Update to admin interface- This interface has been cleaned up quite a bit and made a bit nicer. -Rewrite of the YP listing code- The icecast yp code has received a complete overhaul by karl, and it's a much more stable and failure-resistant implementation. -Lots and lots of bugs fixed- Check the ChangeLog for a complete list of these... ----------------------------------------------------------------------------- 2003-10-12 Added documentation 2003-04-23 Support aliases 2003-03-09 Support listening on multiple sockets. 2003-03-08 Support for shoutcast source protocol added. 2003-03-08 Started implementing generic admin interface. Supports (so far): - dynamic configuration of mount fallbacks /admin/fallbacks?mount=/mount&fallback=/fallback - setting of mp3 metadata /admin/metadata?mount=/mount&mode=updinfo&song=New%20Title - dumping raw xml stats /admin/rawstats - listing all connected clients on a mountpoint: /admin/listclients?mount=/mountname 2003-03-05 Implemented the ability to reread the config file on SIGHUP. For now, this does not affect configuration for currently running sources (only new sources and global parameters like max-listeners) 2003-03-02 More features: -- per mountpoint listener maxima -- static configuration of mountpoint fallbacks -- stream dumping (write incoming stream to disk) 2003-02-27 Fix log buffering on win32 - previously, logs were never flushed, so they only got output every few tens or hundreds of lines. 2003-02-27 Support new icy-audio-info header, to communicate various parameters to clients and yp servers, including sample rate, quality, channels, bitrate 2003-02-25 Full support for relaying mp3 metadata (if turned on in config file) 2003-02-25 Allow configuration of maximum client queue length (in bytes) 2003-02-14 Finished full IPv6 support. 2003-02-12 Allow configuring local mountpoint seperately from remote mountpoint for relays 2003-02-12 Per mountpoint usernames and passwords (for sources) 2003-02-11 Now that it's been officially assigned, use application/ogg instead of application/x-ogg 2003-02-07 Allow relaying of mp3 streams from icecast 1.x and shoutcast 2003-02-07 Added ability to configure individual relays (rather than just all streams from a single server). 2003-02-03 Added support for YP directory services listings are only used by the yp listing routines 2003-02-03 Support command line parameter -b to run in the background (not supported on win32) 2002-12-31 Implement configurable mountpoint fallbacks (on source exit, clients are transferred to another mountpoint automatically, without disconnecting them) 2002-12-31 Implemented full mp3 metadata support. (older stuff is missing from here)
