PipeWire é um servidor para streams de áudio e vídeo no Linux, chega a sua versão 0.3.52 para correção de bugs críticos, confira.

 

Lançado o PipeWire 0.3.52

PipeWire é um servidor para lidar com streams de áudio e vídeo e hardware no Linux. Foi criado por Wim Taymans da Red Hat. Ele lida com roteamento de multimídia e processamento de pipeline. Alguns de seus objetivos são: Trabalhar com aplicativos Flatpak em sandbox. Wikipédia

 

O anúncio foi feito em 09 de Junho de 2022

"Esta é uma versão de correção de bugs compatível com API e ABI com versões anteriores
0.3.x versões."

Destaques

• Adicionado 44,1 KHz às taxas de amostragem permitidas. O servidor agora pode alternar por padrão entre 48KHz e 44,1KHz.
• Os fluxos agora alocam menos recursos.
• Corrigido alguns bugs que poderiam fazer o servidor travar.
• O Bluetooth agora suporta o codec do fornecedor LC3plus.
• Muitas correções de bugs e melhorias.

Log completo no quadro abaixo.

PipeWire Add 44.1KHz to allowed samplerates. Avoid setting the locale. Avoid use-after-free when destroying a node from spa-node-factory. Avoid using reallocarray when not available. Set port alias is not otherwise set. Modules Improve filter-chain parsing and error reporting. Handle empty nodes. (#1950) Handle destroy of globals and factory in most modules. (#565) Add refcounts to client and resources to handle destroy of the protocol. (#565) Handle global node.name in filter-chain and loopback again, use it to construct unique stream names. Avoid a wrapped pw-node in the adapter. This reduces resources allocated for streams. Fix a crash when module-x11-bell was unloaded. (#2392) Add a new module-pipe-tunnel that can write/read data from a UNIX pipe. Tools Fix DSD playback again in pw-cat. Add -n option to pw-loopback to set node names. Add -P option to pw-cat to pass properties to the stream. Support stdin/stdout in pw-cat. (#2387) pw-dump now also dumps object removal when monitoring. (#2426) SPA Avoid duplicate param results in pw-dump for ports. Avoid endless loops in audioconvert for badly behaving client. (#2359) Scale max-error in alsa based on quantum and avoid logging a warning when starting. Improve debug of failed format conversion. (#2383) Handle offset in the audio dsp mixer inputs and clamp to the max buffer size. Add option to disable locale support for JSON number conversion. Add support for Astro A20 Gen2. Fix some of the test sources, the flags were not set correctly. Add camera location as property in libcamera and let the session manager Generate a localized description. Fix some crashes due to wrong vargar types in v4l2 controls. (#2400) Improve ALSA resync behaviour. (#2257) Add support for Komplete Audio 6 MK2. Improve loop cancel while iterating. Try not to mix surround channels and AUX channels. Make card with many ports look better when not using the Pro Audio profile. Vulkan filters were added. Bluetooth Add LC3plus vendor codec. Handle unsupported indicators better. Ensure multiple devices on an adapter use different codecs because one endpoint can only be used by one device at a time. Fix bitpool control as a follower. Handle bluetooth errors better. Speed up bluetooth connection by only waiting for the profiles supported by the adapter. The dummy AVRCP player is disabled by default because it seems to break more devices than it fixes. pulse-server Add initial stream latency property so that devices can be started with a resonably accurate latency. Fix ringbuffer underrun case. (#2366) module-native-protocol-tcp now has a auth-anonymous option to give full access to the clients. Report a node as being moved when it is still moving. This improves compatibility with pasystray. Avoid overallocating message memory. Don't export NETWORK nodes in zeroconf. (#2384) Fix stride for TrueHD and DTSHD passthrough. (#2284) Make sure we don't send too small audio fragments. Fixes capture from multiple tabs in Chrome. (#2418) Rework module handling some more. Use the new native module-pipe-tunnel for pipe-sink and pipe-source. Implement the STREAM_MOVED message when a stream got moved. (#2407) Fix a potential segfault when stopping the server and a TCP module as still loaded. ALSA Add support for updating sw_params at runtime, mostly the min-avail param. Capture and playback nodes are now assumed to use a different clock and will activate the adaptive resampler when linked. This assumption is removed in Pro Audio mode. This provide a better experience out of the box with most devices. JACK Fix setting properties with PIPEWIRE_PROPS again. Don't use 64 bits atomic operations for sync_timeout. (#1867) Cleanup in error cases was improved, avoiding some crashes. (#2394) GStreamer Fix pipewiresink in mode=provide. (#1980) Share memory into a new buffer in pipewiresrc to avoid buffer corruption. Fixes to the source and fd use. It is now possible to set client properties as well. (#1573)
