PipeWire 0.3.57 (2022-09-02)

This is a bugfix release that is API and ABI compatible with previous 0.3.x releases.

Highlights

• Support masking of conf.d/ files. (#2629)
• Use org.freedesktop.portal.Realtime when available. This does the correct PID/TID mappings to make realtime also work from flatpaks.
• Fix rate adjustement logic in pulse-tunnel. This would cause increasing delays and hickups when using tunnels. (#2548)
• Add OPUS as a new vendor codec. Add OPUS-A2DP spec. PipeWire can now send and reveive OPUS data over bluetooth.
• An AAC decoder was added so that PipeWire can now also function as an A2DP AAC receiver.
• Fix some issues where the wrong samplerate was used. (#2614)
• Fix rate match for sources. This fixes an error where follower sources would generate many resync warnings.
• Many more bugfixes and improvements.

PipeWire

• Support masking of conf.d/ files. (#2629)
• Add some more debug info to memfd.
• Improve data-loop invoke method. Also flush pending items. (#2631)
• Add a filter-chain systemd service file than can be used to start custom filters placed in ~/.conf/pipewire/filter-chain.d/ (#2553)
• Improve triggered timestamps for remote nodes.
• Fix some potential cross compilation problems due to wrong host_machine.
• Check return values of pw_getrandom().

Tools

• Updates to pw-cli manpages. (#2552)
• Remove the pw-cli dump command. It is mostly implemented as part of wpctl status, pw-dump, pw-link, pw-top and others.
• Clean up resource in pw-cat correctly on errors. (#2651)

Modules

• Fix compilation of AVB on big-endian. Enable AVB only on Linux.
• Use org.freedesktop.portal.Realtime when available. This does the correct PID/TID mappings to make realtime also work from flatpaks.
• Fix compilation of ROC module when headers are missing. (#2513)
• Improve some error cleanup paths in protocol-native. Improve connect and disconnect.
• Fix a potential crash in FFT unload in filter-chain.
• Implement PIPEWIRE_NOTIFICATION_FD for notification when the socket is ready.
• Try to use rtkit if set_nice() fails.
• Fix rate adjustement logic in pulse-tunnel. This would cause increasing delays and hickups when using tunnels. (#2548)
• Handle disconnect in pulse-tunnel.

Bluetooth

• Add OPUS as a new vendor codec. Add OPUS-A2DP spec. PipeWire can now send and reveive OPUS data over bluetooth.
• An AAC decoder was added so that PipeWire can now also function as an A2DP AAC receiver.

SPA

• Tweak the resampler window function some more. (#2574)
• Improve format convert performance in some fallback cases.
• Fix rounding in format conversion on ARM NEON.
• Fix libcamera build error. (#2575)
• Fix some issues where the wrong samplerate was used. (#2614)
• Don't wait for more samples that can fit in the ringbuffer in ALSA.
• Improve buffer size handling in audioconvert, scale the buffers based on the rate conversion and make things work with really large rate conversions as well.
• Add more and better debug for ALSA devices.
• Improve channel mix: Filter FC and LFE when copying from a different layout. Implement STEREO from FC. Avoid generating REAR from FC in PSD mode.
• Fix rate match for sources. This fixes an error where follower sources would generate many resync warnings.
• Improve ALSA format negotiation. If the ALSA node is not running and there was a previously configured format, close and reopen the device to enumerate and accept all possible formats again. (#2625).

ALSA

• The alsa plugin will now also save the volumes set with the control API. This saves the volumes set with alsa-mixer, for example.

Pulse-server

• Flatpak apps with devices=all (Zoom) will now be granted Manager permissions.
• Small tweaks to the amount of data sent to clients to work around an issue in freerdp.

JACK

• Clean up the transport correctly when closing a client. (#2569)
• Match context properties in addition to node properties for the jack client rules. (#2580)
• Make sure to return an error when disconnected from the server. (#2606)
• Fix thread cast problem in jack_client_thread_id().
• Increase jack_client_name_size() length and make sure we have space for the \0 byte.
• JACK clients from the same application will be added to the same group so that they share the quantum and rate.
