O PipeWire expande as capacidades do PulseAudio com recursos para trabalhar com fluxos de v\u00eddeo, permitindo o processamento de \u00e1udio com lat\u00eancias m\u00ednimas e um novo modelo de seguran\u00e7a para gerenciar o acesso em n\u00edvel de dispositivos e fluxos individuais. O projeto \u00e9 suportado pelo GNOME e j\u00e1 est\u00e1 sendo amplamente utilizado no Fedora Linux para grava\u00e7\u00e3o de conte\u00fado de tela (screencasting) e compartilhamento de tela em ambientes baseados no Wayland.

As mudan\u00e7as possibilitaram a execu\u00e7\u00e3o de uma camada para garantir a compatibilidade com o servidor de \u00e1udio JACK, cuja performance \u00e9 compar\u00e1vel \u00e0 do JACK2.\n<li class=\"l\"> Foi reestruturado e declarado est\u00e1vel <noindex><a rel=\"nofollow\" href=\"https:\/\/pipewire.github.io\/pipewire\/\">API<\/a><\/noindex>. Todas as altera\u00e7\u00f5es futuras na API est\u00e3o previstas para serem feitas sem quebrar a compatibilidade reversa com aplicativos existentes.\n<li class=\"l\"> Foi inclu\u00eddo um gerenciador de sess\u00f5es, permitindo gerenciar o grafo de n\u00f3s multim\u00eddia no PipeWire, al\u00e9m de adicionar novos fluxos. Por enquanto, o gerenciador oferece apenas um conjunto b\u00e1sico de fun\u00e7\u00f5es e ser\u00e1 expandido ou substitu\u00eddo por uma op\u00e7\u00e3o mais funcional e flex\u00edvel no futuro, como <noindex><a rel=\"nofollow\" href=\"https:\/\/gitlab.freedesktop.org\/gkiagia\/wireplumber\">WirePlumber<\/a><\/noindex>.\n<li class=\"l\"> As bibliotecas inclu\u00eddas foram aprimoradas para garantir compatibilidade com PulseAudio, JACK e ALSA, permitindo que o PipeWire funcione com aplicativos existentes que dependem de outros sistemas de \u00e1udio. A biblioteca para ALSA est\u00e1 quase pronta, mas as bibliotecas para JACK e PulseAudio ainda precisam de melhorias. O PipeWire ainda n\u00e3o est\u00e1 pronto para substituir totalmente o PulseAudio e o JACK, mas quest\u00f5es de compatibilidade ser\u00e3o uma prioridade em lan\u00e7amentos futuros.\n<li class=\"l\"> Alguns plugins do GStreamer foram inclu\u00eddos para intera\u00e7\u00e3o com o PipeWire. O plugin pipewiresrc, que usa o PipeWire como fonte de \u00e1udio, na maioria das situa\u00e7\u00f5es funciona sem problemas. O plugin pipewiresink para sa\u00edda de \u00e1udio atrav\u00e9s do PipeWire ainda tem alguns problemas conhecidos.\n<li class=\"l\"> O suporte ao PipeWire 0.3 <noindex><a rel=\"nofollow\" href=\"https:\/\/www.mail-archive.com\/release-team@gnome.org\/msg08297.html\">est\u00e1 integrado<\/a><\/noindex> no gerenciador de janelas Mutter, desenvolvido pelo projeto GNOME.\n<\/ul>\n<p>Cabe lembrar que o PipeWire expande a aplica\u00e7\u00e3o do PulseAudio ao processar quaisquer fluxos multim\u00eddia e \u00e9 capaz de misturar e redirecionar fluxos de v\u00eddeo. O PipeWire tamb\u00e9m oferece recursos para gerenciar fontes de v\u00eddeo, como dispositivos de captura de v\u00eddeo, webcams ou conte\u00fado de tela produzido por aplicativos. Por exemplo, o PipeWire permite que v\u00e1rios aplicativos trabalhem juntos com a webcam e resolve problemas com a captura segura de conte\u00fado de tela e acesso remoto \u00e0 tela em um ambiente Wayland. <\/p>\n<p>O PipeWire tamb\u00e9m pode atuar como um servidor de \u00e1udio, proporcionando lat\u00eancias m\u00ednimas e oferecendo funcionalidade que combina recursos <noindex><a rel=\"nofollow\" href=\"https:\/\/github.com\/PipeWire\/pipewire\/wiki\/PulseAudio\">PulseAudio<\/a><\/noindex> e <noindex><a rel=\"nofollow\" href=\"https:\/\/github.com\/PipeWire\/pipewire\/wiki\/JACK\">JACK<\/a><\/noindex>, incluindo as necessidades de sistemas profissionais de processamento de \u00e1udio, nas quais o PulseAudio n\u00e3o poderia competir. Al\u00e9m disso, o PipeWire oferece um modelo de seguran\u00e7a avan\u00e7ado que permite gerenciar o acesso em n\u00edvel de dispositivos individuais e fluxos espec\u00edficos, facilitando a organiza\u00e7\u00e3o do encaminhamento de \u00e1udio e v\u00eddeo de e para cont\u00eaineres isolados.
