PipeWire har udvidede funktioner sammenlignet med PulseAudio til behandling af videostr\u00f8mme, mulighed for lydbehandling med minimal forsinkelse og en ny sikkerhedsmodel til kontrol af adgang p\u00e5 niveau med enkelte enheder og str\u00f8mmene. Projektet underst\u00f8ttes i GNOME og anvendes allerede som standard i Fedora Linux. Koden til projektet er skrevet i C og distribueres under LGPLv2.1.      <\/p>\n<p>Vigtige \u00e6ndringer i PipeWire 0.3.35:  <\/p>\n<ul>\n<li class=\"l\"> Underst\u00f8ttelse af S\/P-DIF protokollen til overf\u00f8rsel af digital lyd via optiske forbindelser og HDMI er blevet tilf\u00f8jet.\n<li class=\"l\"> Bluetooth-codecs er flyttet til separate plugins, som indl\u00e6ses dynamisk.\n<li class=\"l\"> En r\u00e6kke vigtige rettelser vedr\u00f8rende MIDI-support er blevet implementeret.\n<li class=\"l\"> Ydeevnen af skypeforlinux-applikationen er forbedret ved at tilf\u00f8je en binding, der tvinger brugen af S16-formatet til overf\u00f8rsel af oplysninger om lydindgangs- og -udgangsenheder. \u00c6ndringen har l\u00f8st et problem, der tidligere f\u00f8rte til manglende lyd fra den anden part i forbindelse.\n<li class=\"l\"> Antallet af lydformater til blanding er blevet udvidet.\n<li class=\"l\"> Et nyt interface til indl\u00e6sning af moduler er blevet tilf\u00f8jet. Plugins kan bruge dette interface til at anmode om indl\u00e6sning af spa-plugins.\n<li class=\"l\"> St\u00f8rrelsen p\u00e5 parameterr\u00e6kken er blevet \u00f8get, hvilket tidligere kunne v\u00e6re utilstr\u00e6kkeligt til at rumme alle egenskaber for noder med et stort antal kanaler.\n<li class=\"l\"> Driveraktivering ved installation af loopback-forbindelser er blevet sikret.\n<li class=\"l\"> I <a class=\"wpil_keyword_link\" href=\"https:\/\/prohoster.info\/da\/server\/dts-newyork\/\"   title=\"serveren\" data-wpil-keyword-link=\"linked\"  data-wpil-monitor-id=\"2670\">serveren<\/a> Device-restore-udvidelsen er implementeret, hvilket g\u00f8r det muligt at konfigurere IEC958 (S\/P-DIF) codecs, der underst\u00f8ttes af lydoutput-enheden via pavucontrol-v\u00e6rkt\u00f8jet.    <\/ul>\n<p>Lad os minde om, at PipeWire udvider PulseAudios anvendelsesomr\u00e5de ved at kunne h\u00e5ndtere enhver mediestr\u00f8m og er i stand til at blande og omdirigere videostr\u00f8mme. PipeWire tilbyder ogs\u00e5 muligheder for at styre video kilder, s\u00e5som video capture-enheder, webkameraer eller indhold, der vises af applikationer p\u00e5 sk\u00e6rmen. For eksempel giver PipeWire mulighed for at organisere samarbejde mellem flere applikationer med et webkamera og l\u00f8ser problemer med sikker sk\u00e6rmfangst og fjernadgang til sk\u00e6rmen i Wayland-milj\u00f8et.         <\/p>\n<p>PipeWire kan ogs\u00e5 fungere som en lyd <a class=\"wpil_keyword_link\" href=\"https:\/\/prohoster.info\/da\/server\/dts-los-angeles\/\"   title=\"server\" data-wpil-keyword-link=\"linked\"  data-wpil-monitor-id=\"3746\">server<\/a>, som sikrer minimale forsinkelser og leverer funktionalitet, der kombinerer mulighederne fra PulseAudio og JACK, herunder tager h\u00f8jde for behovene fra professionelle lydbehandlingssystemer, som PulseAudio ikke kunne opfylde. Derudover tilbyder PipeWire en udvidet sikkerhedsmodel, der muligg\u00f8r adgangsstyring p\u00e5 niveau med individuelle enheder og specifikke str\u00f8mme, og som forenkler h\u00e5ndtering af lyd og video fra isolerede containere og til dem. Et af de prim\u00e6re m\u00e5l er at underst\u00f8tte selvforsynende applikationer i Flatpak-format og arbejde i et grafisk stack baseret p\u00e5 Wayland.      <\/p>\n<p>Hovedfunktioner:  <\/p>\n<ul>\n<li class=\"l\"> Optagelse og afspilning af lyd og video med minimale forsinkelser;  <\/li>\n<li class=\"l\"> V\u00e6rkt\u00f8jer til realtidsbehandling af video og lyd;  <\/li>\n<li class=\"l\"> Multiprocess arkitektur, der muligg\u00f8r delt adgang til indhold mellem flere applikationer;    <\/li>\n<li class=\"l\"> Behandlingsmodel baseret p\u00e5 en graf af multimediaknuder med underst\u00f8ttelse af feedbacksl\u00f8jfer og atomare opdateringer af grafen. Mulighed for tilslutning af behandlere b\u00e5de internt i serveren og eksterne plugins;  <\/li>\n<li class=\"l\"> Effektiv gr\u00e6nseflade til adgang til videostr\u00f8mme via overf\u00f8rsel af filbeskrivelser og adgang til lyd via delte ringbuffer;  <\/li>\n<li class=\"l\"> Mulighed for behandling af multimediedata fra enhver proces;  <\/li>\n<li class=\"l\"> Tilstedev\u00e6relse af en GStreamer-plugin for at forenkle integrationen med eksisterende applikationer;  <\/li>\n<li class=\"l\"> Underst\u00f8ttelse af isolerede milj\u00f8er og Flatpak;  <\/li>\n<li class=\"l\"> Underst\u00f8ttelse af plugins i SPA-format (Simple Plugin API) og mulighed for at oprette plugins, der arbejder i h\u00e5rd realtid;  <\/li>\n<li class=\"l\"> Fleksibel system til koordinering af anvendte multimediaformater og tildeling af buffers;  <\/li>\n<li class=\"l\"> Brug af en enkelt baggrundsproces til routing af lyd og video. Mulighed for at fungere som lydenhed, hub til at levere video til applikationer (for eksempel til gnome-shell screencast API) og server til kontrol af adgang til hardwareenheder til videooptagelse.  <\/li>\n<p>Kilde: <a content=\"nofollow\" rel=\"nofollow\" href=\"https:\/\/www.opennet.ru\/opennews\/art.shtml?num=55777\">opennet.ru<\/a> <\/p>","protected":false,"gt_translate_keys":[{"key":"rendered","format":"html"}]},"excerpt":{"rendered":"<p>\u041e\u043f\u0443\u0431\u043b\u0438\u043a\u043e\u0432\u0430\u043d \u0432\u044b\u043f\u0443\u0441\u043a \u043f\u0440\u043e\u0435\u043a\u0442\u0430 PipeWire 0.3.35, \u0440\u0430\u0437\u0432\u0438\u0432\u0430\u044e\u0449\u0435\u0433\u043e \u043c\u0443\u043b\u044c\u0442\u0438\u043c\u0435\u0434\u0438\u0439\u043d\u044b\u0439 \u0441\u0435\u0440\u0432\u0435\u0440 \u043d\u043e\u0432\u043e\u0433\u043e \u043f\u043e\u043a\u043e\u043b\u0435\u043d\u0438\u044f, \u0438\u0434\u0443\u0449\u0438\u0439 \u043d\u0430 \u0437\u0430\u043c\u0435\u043d\u0443 PulseAudio.
