PipeWire utvider PulseAudios muligheter med verkt\u00f8y for videostr\u00f8mmer, muligheten for lavlatens lydbehandling og en ny sikkerhetsmodell for tilgangsstyring p\u00e5 niv\u00e5 med individuelle enheter og str\u00f8mmene. Prosjektet st\u00f8ttes av GNOME og brukes allerede som standard i Fedora Linux. Koden til prosjektet er skrevet i C og distribueres under LGPLv2.1-lisensen.      <\/p>\n<p>De viktigste endringene i PipeWire 0.3.33:  <\/p>\n<ul>\n<li class=\"l\"> Muligheten for automatisk bytte mellom Bluetooth-profiler HSP (headset-modus) og A2DP (h\u00f8ykvalitets lydutgang) er implementert.\n<li class=\"l\"> I Pro Audio-profilen er st\u00f8tten for virtuelle lydkilder og utgangsenheter forbedret.\n<li class=\"l\"> Forbedret synkronisering av formatmodifikatorer ved felles bruk av direkte minneaksessbuffere (DMA-BUF) av flere klienter.\n<li class=\"l\"> I seksjonen for multimedia-noder er det implementert st\u00f8tte for samtidig bruk av flere samplingsfrekvenser (som standard deaktivert).\n<li class=\"l\"> I lagringslaget for kompatibilitet med PulseAudio er det implementert en modul module-switch-on-connect for \u00e5 emulere PulseAudio-adferd ved tilkobling av nye enheter.    <\/ul>\n<p>Vi minner om at PipeWire utvider bruksomr\u00e5det til PulseAudio ved \u00e5 h\u00e5ndtere alle multimedia-str\u00f8mmer, og er i stand til \u00e5 blande og omdirigere videostr\u00f8mmer. PipeWire tilbyr ogs\u00e5 muligheter for \u00e5 h\u00e5ndtere videokilder, som videoinnsamlingsenheter, webkameraer eller innhold som utgis av applikasjoner. For eksempel gj\u00f8r PipeWire det mulig \u00e5 organisere samarbeid mellom flere applikasjoner med et webkamera, og l\u00f8ser problemer med sikker innhenting av skjerminnhold og ekstern tilgang til skjermen i et Wayland-milj\u00f8.         <\/p>\n<p>PipeWire kan ogs\u00e5 fungere som lyd... <a class=\"wpil_keyword_link\" href=\"https:\/\/prohoster.info\/no\/server\/dts-los-angeles\/\"   title=\"serveren\" data-wpil-keyword-link=\"linked\"  data-wpil-monitor-id=\"3736\">serveren<\/a>, som sikrer minimale forsinkelser og tilbyder funktionalitet, der kombinerer mulighederne fra PulseAudio og JACK, herunder hensyntagen til behovene hos professionelle lydbehandlingssystemer, som PulseAudio ikke kunne opfylde. Desuden tilbyder PipeWire en udvidet sikkerhedsmodel, der muligg\u00f8r adgangsstyring p\u00e5 niveau med individuelle enheder og specifikke str\u00f8mme, og der letter organiseringen af lyd- og videopassthrough fra og til isolerede containere.
