Au niveau de l'API et de l'ABI, la version 1.0 est r\u00e9trocompatible avec la branche 0.3. PipeWire est pr\u00e9sent\u00e9 comme un serveur destin\u00e9 \u00e0 remplacer le serveur audio PulseAudio et se distingue par l'ajout de moyens pour travailler avec des flux vid\u00e9o, la possibilit\u00e9 de traiter l'audio avec des latences minimales et un nouveau mod\u00e8le de s\u00e9curit\u00e9 pour g\u00e9rer l'acc\u00e8s au niveau des appareils et des flux individuels. Le projet est soutenu par GNOME et est d\u00e9j\u00e0 utilis\u00e9 par d\u00e9faut dans Fedora Linux, RHEL, Ubuntu, Debian, SUSE\/openSUSE et de nombreuses autres distributions Linux. Le code du projet est \u00e9crit en C et est distribu\u00e9 sous licence LGPLv2.1.      <\/p>\n<p>PipeWire offre des possibilit\u00e9s de traitement de tous les flux multim\u00e9dias, capable de mixer et de rediriger des flux vid\u00e9o, pouvant \u00eatre utilis\u00e9 pour g\u00e9rer des sources vid\u00e9o, telles que des appareils de capture vid\u00e9o, des webcams ou le contenu des applications \u00e0 l'\u00e9cran. Par exemple, PipeWire permet d'organiser une collaboration entre plusieurs applications avec une webcam et r\u00e9sout des probl\u00e8mes de capture s\u00e9curis\u00e9e du contenu de l'\u00e9cran et d'acc\u00e8s distant \u00e0 l'\u00e9cran dans un environnement Wayland.         <\/p>\n<p>PipeWire peut \u00e9galement agir en tant que serveur audio <a class=\"wpil_keyword_link\" href=\"https:\/\/prohoster.info\/fr\/server\/dts-los-angeles\/\"   title=\"de serveurs\" data-wpil-keyword-link=\"linked\"  data-wpil-monitor-id=\"3827\">de serveurs<\/a>, offrant des latences minimales et fournissant une fonctionnalit\u00e9 combinant les capacit\u00e9s de PulseAudio et de JACK, tout en tenant compte des besoins des syst\u00e8mes de traitement audio professionnels, ce que PulseAudio ne pouvait pas revendiquer. De plus, PipeWire propose un mod\u00e8le de s\u00e9curit\u00e9 avanc\u00e9 permettant de g\u00e9rer l'acc\u00e8s au niveau des appareils individuels et des flux sp\u00e9cifiques, facilitant le passage de l'audio et de la vid\u00e9o dans et hors des conteneurs isol\u00e9s.

Pour ALSA, la planification bas\u00e9e sur l'IRQ est activ\u00e9e dans le profil Pro-Audio, permettant d'atteindre des latences au niveau de JACK. Le support des anciennes et nouvelles versions de webrtc-audio-processing a \u00e9t\u00e9 ajout\u00e9. Dans pw-cat, le support des fichiers DFF DSD a \u00e9t\u00e9 ajout\u00e9.
