e hatisitsoeng tokollo e kholo ea morero PipeWire 0.3.0, ho hlahisa seva se secha sa multimedia ho nka sebaka sa PulseAudio. PipeWire e holisa bokhoni ba PulseAudio ka bokhoni ba ho phallela video, ts'ebetso ea molumo o tlase oa latency, le mofuta o mocha oa ts'ireletso bakeng sa taolo ea phihlello ea sesebelisoa le boemo ba phallo. Morero o tšehetsoa ho GNOME mme o se o ntse o sebelisoa ka mafolofolo ho Fedora Linux bakeng sa ho rekota skrineng le ho arolelana skrineng libakeng tse thehiloeng ho Wayland. Khoutu ea morero e ngotsoe ka C le ajoa ke e fuoe laesense tlasa LGPLv2.1.

ka sehloohong fetola ho PipeWire 0.3:

• The thread processing scheduler e hlophisitsoe bocha ka botlalo. Liphetoho li entse hore ho khonehe ho tsamaisa lera ho netefatsa hore ho lumellana le seva sa molumo oa JACK, ts'ebetso ea eona e bapisoang le JACK2.
• E hlophisitsoe bocha mme e phatlalalitsoe e tsitsitse API. Liphetoho tsohle tse ling ho API li reriloe ho etsoa ntle le ho senya ho lumellana le morao-rao le likopo tse teng.
• E kenyelletsa mookameli oa seboka ea u lumellang ho laola graph ea multimedia node ho PipeWire, hammoho le ho eketsa melapo e mecha. Hajoale, mookameli o fana feela ka sete e bonolo ea mesebetsi ea mantlha mme nakong e tlang e tla atolosoa kapa e nkeloe sebaka ke khetho e sebetsang haholoanyane le e feto-fetohang, joalo ka. WirePlumber.
• Lilaebrari tse kenyelletsoeng li ntlafalitsoe ho fana ka ho lumellana le PulseAudio, JACK le ALSA, ho lumella PipeWire hore e sebelisoe le lisebelisoa tse teng tse etselitsoeng ho sebetsa le mekhoa e meng ea molumo. Laeborari ea ALSA e se e loketse, empa lilaebrari tsa JACK le PulseAudio li ntse li hloka mosebetsi. PipeWire ha e so itokisetse ho nka sebaka sa PulseAudio le JACK ka botlalo, empa litaba tsa khokahano e tla ba tsona tse tlang pele litokollong tse tlang.
• Ho kenyellelitsoe ke li-plugins tse ling tsa GStreamer bakeng sa ho sebelisana le PipeWire. Pipewiresrc plugin, e sebelisang PipeWire e le mohloli oa molumo, e sebetsa ntle le mathata maemong a mangata. Pipewiresink plugin bakeng sa tlhahiso ea molumo ka PipeWire ha e so na mathata a mang a tsejoang.
• PipeWire 0.3 tšehetso kopantswe ho mookameli oa fensetere ea Mutter e ntlafalitsoeng ke morero oa GNOME.

A re u hopotse hore PipeWire e holisa boholo ba PulseAudio ka ho sebetsana le melapo efe kapa efe ea multimedia mme e khona ho kopanya le ho tsamaisa melapo ea video hape. PipeWire e boetse e fana ka bokhoni ba ho laola mehloli ea video, joalo ka lisebelisoa tsa ho hapa livideo, lik'hamera tsa marang-rang, kapa litaba tsa skrineng sa ts'ebeliso. Mohlala, PipeWire e lumella lits'ebetso tse ngata tsa webcam ho sebetsa 'moho le ho rarolla mathata ka ho ts'oara skrineng se sireletsehileng le phihlello ea skrine e hole tikolohong ea Wayland.

PipeWire e ka sebetsa joalo ka seva ea molumo, e fana ka latency e fokolang le ho kopanya ts'ebetso PulseAudio и Jack, ho kenyeletsoa ho ela hloko litlhoko tsa lits'ebetso tsa profeshenale tsa audio audio, tseo PulseAudio e neng e sa khone ho li bolela. Ho feta moo, PipeWire e fana ka mofuta o tsoetseng pele oa ts'ireletso o lumellang taolo ea phihlello ho sesebelisoa le boemo ba molatsoana, 'me e nolofaletsa ho tsamaisa molumo le video ho ea le ho tsoa lijaneng tse ka thoko. E 'ngoe ea lipheo tsa mantlha ke ho ts'ehetsa lits'ebetso tse ikemetseng tsa Flatpak le ho sebetsa ho stack ea litšoantšo tse thehiloeng ho Wayland.
