UPGRADE – Shoutcast DNAS Server 2.6.1 build 777

Der Shoutcast Server ist eine kostenlose Anwendung zum Streaming-Audio über das Internet, das für Windows- und Linux-Betriebssysteme entwickelt wurde.

Mit Shoutcast Distributed Network Audio Server (DNAs) kann jeder Audiodateien von einem PC auf Web- oder anderen IP-basierten Netzwerke streamen und übertragen.

Der SHOUTCAST-Server kann zum Streaming von Audio Live oder MP3-Inhalt verwendet werden, der auf dem Server  in einem Verzeichnis gespeichert ist.

Changes from 2.4.7 build 256 to 2.5.1 build 723:

• Added FLV containerisation support for MP3 and AAC streams (add ?type=.flv to compatible stream urls to use)
• Added support for sending title updates to Tunein for DNAS+ streams
• Added ‚minbitrate‘ and ’streamminbitrate‘ options to complement the ‚maxbitrate‘ and ’streammaxbitrate‘ options
• Added ’streambitrate‘ alias for setting both ’streammaxbitrate‘ and ’streamminbitrate‘ to enforce a single allowed bitrate
• Added the HTML5 player to /index.html?sid=0 page for all compatible streams (currently only MP3 streams)
• Added ‚type=x‘ parameter to force specific connection handling (e.g. type=http or type=.flv or type=sc1 or type=sc2 or type=html) irrespective of what the connection may indicate from header and user-agent values)
• Added unlimited listener support when setting ‚maxuser=0‘ to allow any listener connection (the server will still need to be able to support the number of requests when this is enabled to avoid streaming issues)
• Added frame syncing support on all source inputs (direct and relay) to filter out bad stream data
• Added ‚dns‘ mappings of the ‚ip‘ config options (e.g. publicdns -> publicip)
• Added modes to enable / disable only the source and only the listener debugging options via mode=debug?option=source and mode=debug?option=listener respectively
• Added StreamNext=’xxx‘ to the SHOUTcast 1.x-style in-stream title updates (will need listener software updates to be able to make use of this)
• Added samplerate reporting on the appropriate stream pages and log output
• Added rate limiting on all listener handlers to help reduce listeners getting too far ahead or adverts being resumed from at the in-correct position (or playing the filler as well as the adverts)
• Added ‚ratelimit‘ to enable control of the frame rate limiting feature (set ratelimit=0 to disable if it causes issues)
• Added ‚adtestfile‘, ‚adtestfileloop‘, ’streamadtestfile‘, ’streamadtestfileloop‘, and related handling to aid in testing advert triggers will work (see documentation for details)
• Added ‚adminfile‘ support which allows for restricting unwanted access to admin.cgi to only valid IP / hostnames added intto the ’sc_serv.admin‘ file (see documentation for details)
• Added ‚forceshortsends‘ support which allows for mimicking restricted network output which can occassionally be helpful for debugging
• Added ‚adminnowrap‘ support to allow for disabling some of the mobile friendly CSS / HTML changes for the stream admin page and its display of the listener list
• Added a sanitised configuration settings view mode for the server administrator to aid in checking that the DNAS is using the settings it is meant to be using
• Added /currentmetadata?sid=# which is a more accessible version of the admin.cgi mode=viewxml or mode=viewjson and page=5 requests for getting the extended stream metadata
• Added support to make better use of the X-Forwarded-For HTTP header (use usexff=0 to disable this change) which is helpful if all listeners appear to be connected from the local machine due to front-facing services
• Added proper handling of HTTP HEAD requests to resolve a number of issues with unexpected listener connections and failed source connections
• Added a ‚kick duplicates‘ option to the stream administrator page to make it easier to kick duplicate connections from the same user agent and address (see documentation for how to use this in a script)
• Added support for direct HTTP sources (e.g. Icecast based sources) to be accepted when providing MP3 and AAC based stream content)
• Added support for SHOUTcast 1.x sources to be accepted on ‚portbase‘ and not ‚portbase+1‘ as per the SHOUTcast 1.x protocol specification which makes it possible for all sources (1.x and 2.x) to be accepted on a single port instead of needing two ports (see documentation for details and limitations of this mode)
• Changed authhash management to improve integration with the Radionomy platform and services now being offered for SHOUTcast broadcasters
• Changed the default CSS / HTML output to adjustements to work better on mobile devices / small screens including consolidating and removing some of the information on the summary pages
• Changed the YP update to be able to do a full re-add of the stream on update incase of YP-side issues on add
• Changed the YP update handling to be more dynamic to aid with remote clustering fixes
• Changed to use a new scheduler which allows the server to be more flexible and allows the rate limiting support to work correctly
• Changed to require a key press if running normally (non-daemon and non-service modes) when a major issue occurs of the server cannot be run
• Changed 1.x source handling to check the password earlier in the connection steps which allows for quicker checking and setup of the source or rejection as applicable
• Changed the the existing playing and admin metadata responses to include extended metadata (if available)
• Changed the tailing mode to match the 1.x DNAS so it will now only show the log output from when opening the tailing view
• Changed title update to clarify why certain title updates are being rejected
• Changed the way that advert triggers are detected and processed to increase the reliability of advert triggers being actioned
• Changed some of the page icons to appear more visible on dark backgrounds
• Changed log output to only show ‚Terminating listeners…‘ if there are listeners
• Changed some more internal data sctructures to provide additional memory reductions on per-listener basis
• Changed applicable timeout handling to go through a common handler which now ensures that per-stream overrides on the timeouts are correctly applied
• Changed to indicate CDN mode on backup relay connections
• Changed the internal handling of the config items to better handle large stream ids so as to save memory if not using sequential streamids (which speeds up config handling as well as potentially saving a lot of memory)
• Changed to check and abort starting the DNAS if no source passwords are specified
• Changed some of the log start-up wording messages
• Changed the Flash Policy Server to generate the response immediately to reduce time to provide a response
• Changed to not check for <policy-file-request/> if the Flash Policy Server is not enabled on the port
• Changed the HTTP handler to reduce the time to process requests when first processing the request
• Changed to show the bitrate of the skipped files to help with diagnosing why a file was skipped
• Changed handling of relay and direct 1.x sources to improve consistency between them and reduce the time to start a relay connection
• Changed the 2.x relay handling to reduce time to setup the relay connection as well as reducing memory for the connection setup
• Changed file / advert checking to also check the samplerate to improve reliabity of file / advert inserts
• Changed the stream login / logout options to have ‚Stream‘ in front of them to make it clearer vs the main Server actions
• Changed to look for SSLv2 / SSLv3 / TLSv1.x connections and abort them as we do not support HTTPS connections and this was causing false source connection attempts
• Changed debugging output to make it easier to see the full filepath of the control files being used
• Changed when the YP ‚add‘ is issued to prevent it spamming the metrics system if the connnection quickly fails (e.g. when running a relay that cannot connect to the source)
• Changed SHOUTcast 1.x and HTTP listener connection handling to be done separately which allows us to provide an optimised HTTP experience than the prior shared handling
• Changed the debugging options admin page to make it easier to enable groups of options and find other related usage changes
• Changed the help / documentation links to use a more complete page which better details information
• Changed the Windows version to make use of a modified pthread-win32 to make internal handling more consistent between OS platforms
• Changed the ‚kick all‘ button to span across all of ‚kick‘ actions and to respond to clicks anywhere in the element

• Changed the ’sources‘ page to show the direct stream urls of the configured streams
• Changed error message output to be more consistent between the platform versions
• Changed Windows Vista+ usage to better scale for larger listener numbers compared to using the Windows XP and prior mode

• Changed admin.cgi?mode=history to provide XML and JSON responses like the /played(.html) method can provide
• Changed to ignore empty icy-icq, icy-irc and icy-aim headers which some older sources send and which could cause the source to be incorrectly rejected

• Changed to use HTTPS for all communication the DNAS needs to make
• Changed to show the user agent in the banned connection log messages
• Changed to not save ’streamid‘ when re-writing or editing the config file as the DNAS is able to work this out without needing the option to be present (unlike with older 2.x releases)
• Changed to about direct source connections earlier on if the source password is incorrect than was previously being done
• Fixed handling of XML title updates with escaped characters leading to unexpected title update failures
• Fixed issues with excessive CPU usage due to connections to the DNAS not having enough data ready to be provided or received
