Projektet underst\u00f8ttes i GNOME og anvendes som standard i Fedora Linux, RHEL, Ubuntu, Debian, SUSE\/openSUSE og mange andre Linux-distributioner. Koden til projektet er skrevet i C og distribueres under LGPLv2.1.<\/p>\n<p>PipeWire er baseret p\u00e5 en multiproces-arkitektur, der muligg\u00f8r deling af indholdet mellem flere applikationer.<br \/>\nDer tilbydes muligheder for at behandle alle multimediestr\u00f8mme, blande og omdirigere videostr\u00f8mme samt h\u00e5ndtere video kilder som videofangst enheder, webkameraer eller indhold genereret af applikationer fra sk\u00e6rmen. For eksempel g\u00f8r PipeWire det muligt at organisere samarbejde mellem flere applikationer med et webkamera og l\u00f8ser problemer med sikker sk\u00e6rmfangst og fjernadgang til sk\u00e6rmen i et Wayland-milj\u00f8. <\/p>\n<p>N\u00e5r den bruges som lydserver, kan PipeWire sikre minimal latency og give funktionalitet, der kombinerer funktionerne fra PulseAudio og JACK, herunder at tage hensyn til behovene fra professionelle lydbehandlingssystemer, som PulseAudio ikke kunne im\u00f8dekomme. Derudover tilbyder PipeWire en avanceret sikkerhedsmodel, der muligg\u00f8r adgangsstyring p\u00e5 niveau med individuelle enheder og specifikke streams, hvilket forenkler organiseringen af lyd- og videopassering fra isolerede containere og til dem. Et af hovedm\u00e5lene er at st\u00f8tte selvforsynende applikationer i Flatpak-format og arbejde i grafiske stakke baseret p\u00e5 Wayland.<\/p>\n<p>I den nye version:<\/p>\n<ul>\n<li class=\"l\"> Model for processing data streams based on a graph of nodes has been enhanced with support for asynchronous processing, where the node graph does not block due to lack of output from a specific node, but continues operating using data from that node received in the previous cycle. Thus, at the cost of a one-cycle delay, it is possible to avoid situations where one node blocks the operation of other nodes in the graph.\n<li class=\"l\"> The concept of synchronized node groups (node.sync-group) has been implemented, allowing the creation of groups of nodes that can be activated simultaneously by the scheduler. This function can be used for the simultaneous scheduling of node activation during JACK transport startup.\n<li class=\"l\"> Error output in the configuration file has been improved, with the addition of a mention of the location where the error occurred in the settings (line number and position in line).\n<li class=\"l\"> Support for Explicit Sync technology has been added, allowing applications to inform the Wayland-based compositor about the readiness of the frame output on the screen, which reduces latency and eliminates artifacts in graphic output. Specifically, Explicit Sync addresses output disruption and hangs on systems with NVIDIA GPUs and Wayland support enabled.\n<li class=\"l\"> Muligheden for at definere obligatoriske metadata under godkendelsen af bufferparametre, der bruges til at sikre underst\u00f8ttelse af \u00abExplicit Sync\u00bb, er blevet implementeret.\n<li class=\"l\"> Support for creating and using multiple data processing loops (data-loop) in the client and <a class=\"wpil_keyword_link\" href=\"https:\/\/prohoster.info\/da\/server\/dts-newyork\/\"   title=\"serveren\" data-wpil-keyword-link=\"linked\"  data-wpil-monitor-id=\"2770\">serveren<\/a>. Data processing loops have been enhanced with capabilities for binding to specific CPU cores and setting priorities.\n<li class=\"l\"> The ability to change the debug levels controlling log output without restarting, using metadata, has been provided.\n<li class=\"l\"> The logic for binding peers (nodes in the data stream graph that represent external sources or receivers of data) has been reworked.\n<li class=\"l\"> Patches for handling devices marked as conflicting via ALSA UCM (Use Case Manager) have been accepted.\n<li class=\"l\"> The snapcast-discover module has been added for
